1.1 The Team
G6 Tidal Solutions is made up of 6 team members. A tool that is now popular in team role selection
was used to determine the roles played by each team member. This tool is known as the Belbin
Team Roles Theory. It identifies the typical roles that can be characteristic to varying extents in
individuals working in a group dynamic. A Team Role came to be defined as “A tendency to behave,
contribute and interrelate with others in a particular way.” (Associates, 2007)
The members of the team are each dedicated individuals in pursuit of excellence. Each member
plays a role that is vital in order for the team to succeed as a united entity. There is also a degree of
flexibility with each role to allow for accountability and responsibility of the entire organization.

1.2
The Business Plan
In order for any company to break into a market it needs to have a solid business plan. G6
Tidal Solutions has the following business plan which will aid in the journey towards a bigger
market share.
1.2.1 Mission
The mission of the company is to become a leader in Engineering and Management
consulting by providing clients with best possible solutions and business services which can
fully satisfy their requirements.
1.2.2 Aims and Objectives
Aims: G6 Tidal Solutions aim to provide high quality goods and services to its clients
through intense customer involvement in the design of products.
Objectives:
To be selected from the client, University of Greenwich, as the leading consultingbusiness for the “Tidal-Test-Tank” project
Create and maintain strong client relationships
Become an established consultancy company in the region within the period of 3 to
5 years
To become a international organization after the first 5 years of operation
1.2.3 Marketing and Promotion Strategy
G6 will be employing various media in order to create an awareness of the services it
provides. Seeing as it is a new company, it is important to gain recognition in local areas and
in the rest of the UK as soon as possible. The first step towards becoming known is to list the
company in the Yellow Pages. The next step is to create a company brochure which will be
distributed to education institutions, professional institutions, as well as relevant exhibition
events that are to be attended by the organization. The brochure will be aimed at informing
potential clients of the organisation’s range of products and services. Furthermore the
8/10/2019 419 Instrument
http://slidepdf.com/reader/full/419-instrument 13/126
Tidal Test Tank Project Page | 13
leaflet will highlight G6 Tidal Solution Limited past experience, career highlights as well as
the expertise employed.
Digital advertising marketing will help the company to create awareness outside Greater
London area and outside the English border. The internet is able to give instant exposure to
a vast potential of clients nationally and internationally by combining interactivity,
transaction, and communication. This would allow for lead times to be reduced drastically.
Its usage will boost the business by drawing customers from all over the world. The
company’s website is thus included in any printed literature that the company G6 Tidal
Solutions distributes.
1.2.4 Competitive Advantage
The key advantages of the business are:
The firm is able to provide to customers robust products
Intense quality control and thus providing quality assurance to the client
Competitive prices
Provide optional service of commissioning and installations
Capacity to innovate and modify solutions in short lead times
Ability to work using best practice operations
Create and maintaining a great level of customer satisfaction by involving the
customer in the design of their required product
Strong initial advertising/marketing
Intense customer involvement in design to ensure customer requirements are best
met
1.2.5 Future Products and Services
The company’s focus will be on expanding and upgrading its services according to customer
needs and changes in the market in order to maintain client loyalty as well as the company’s
market share.

1.3
Issues and Constraints
The main issues and constraints faced by a company that is emerging into the business
world are that the organization is at a stage where its members are still building relations
with each other in order to have a truly functioning business. This means that although
individually experienced in respective fields, the members are still learning to work as
united entity whilst trying to build customer relations at the same time. Also, being a new
company, finances are relatively limited and this may make the organisation vulnerable to
losing clients to companies that have more money to spend on projects that are similar to
those pursues by G6 Tidal Solutions Limited.
G6 Tidal Solutions is an infant company that is not yet known by the targeted market. The
main hurdle at hand is to gain the contract with the University of Greenwich in order to
prove experience in the chosen business sector.

2 Project Description
The University of Greenwich’s School of Engineering is in need of a new Tidal -Test- Tank to
be one of the testing facilities in the Hydraulics laboratory. The aim of the group design
project is for groups to propose and tender an all encompassing design to the client, The
University of Greenwich. The School of Engineering is the main vendor and will therefore
select the most suitable design for use out of the 16 competing groups of final year
students.
2.1
Problem Analysis
G6 Tidal Solution was created so that it would be able to propose a design to the client. The
first part of the project is to be able to create a team that works and shows an
understanding of how professional engineering consultants work. That is to create an
identity and set up an organisation that has set work structures and policies that encourage
maximum individual performance.
The next part of the project is to demonstrate a systematic approach to designing and
problem solving. This requires due research to be carried out for the relevant product in
terms of Market research, Product research and all aspects of the product that need to be
considered in order to produce a product that is satisfactory for the client, and also
conforms to relevant Health and safety regulations, and Environmental regulations.

2.2
Team Strategy on Solution Formulation
The Belbin team roles identification tool was very useful in identifying the typical
characteristics of each team member. It aided the team in allocating basic team roles as
shown in Chapter 1.1.1. Once this was achieved, the team’s main strategy to ensure a
successful outcome to the project was as follows.
1. Maintaining high level of discipline to enable effective communication and time
management
2. Encouragement of intellectual input from all members in terms of the direction to be
taken by the team and direct involvement where major decisions needed to be made
3. Intensive research into the product and customer requirements
4. Identification of the different systems within the Main Tidal Test Tank System
5. Allocation of the design of various subsystems that make up the whole tidal test tank
main system to different team members.
6. Protection of confidential information
This strategy has proved to be successful in delivering a complete project within the giventimescales.
2.2.1 Project Management Tools
Each group of people working in a team is likely to have different of managing a project. G6
Tidal Solutions employed the following project management tools to ensure that the project
was carried out to the required quality and within the given time scales.
Time Management
Microsoft Project: The group used this tool to a plan of the tasks that needed to
be carried out and the time allocated for each task.
Every Wednesday from 11am till 5pm was also set aside for carrying out work
that needed to be done in Nelson Computer Labs. This enabled a good work
environment for the group as all members were able to collaborate and carry out
work without delay.
8/10/2019 419 Instrument
http://slidepdf.com/reader/full/419-instrument 17/126
Tidal Test Tank Project Page | 17
Communication
Meetings: Meetings were scheduled for every Tuesday morning from the time
when the project began in order for the team to provide regular updates on
progress made. This also enabled regular intervals to review progress for each
task and to prioritise the most important goals on a weekly basis. It also allowed
the whole team to be aware of what each member was contributing. All meeting
minutes were recorded to show agendas and actions carried out. Relevant
documentation can be found in individual logbooks.
Emails and telephone conversations were used as a means of maintaining good
communication links amongst group members. Emails were also used for
distributing any documentation generated by the tasks carried out by each team
member.
Interviews were carried out for the stakeholders and customers identified in the
report to enable the team to have an understanding of requirements so that a
suitable design could be produced.
Group Motivation
On several occasions the team went out on social luncheons as a team building
technique. This proved to be very effective for team motivation as the team
members were able to interact together in high spirits.
Team members also proved the ability to support each other where certain
members may have needed assistance.
Project Actions
Each team member was able to contribute to the team in an exceptional manner.
Although tasks were delegated by the team manager, team members showed
great initiative by volunteering to carry out tasks they felt they would be able to
deliver. All main decisions were discussed by the team and agreed on so that
work could move on to the next tasks.
The project plan was followed and reviewed and amended depending on the
progress made by the team.
8/10/2019 419 Instrument
http://slidepdf.com/reader/full/419-instrument 18/126
Tidal Test Tank Project Page | 18
Brainstorming: The group had several brainstorming sessions in order to identify
key tasks that needed to be done. Also, brainstorming was used as a means of
identifying the customer requirements and to rank them in order of importance.
Material selection software, CAD software as well as Microsoft package software
were used to produce the bulk of the documented work generated by the team.
The design process involved coming up with designs and ensuring that primary
requirements were satisfied. The design was amended several times in order for
a practical product to be proposed to the client. Some of the designs formulated
were abandoned due to cost factors, some for health and safety reasons, and
some for not being able to meet all primary requirements.
A Shared Drive was created for easy access to group information. All meeting
minutes as well as research literature were uploaded and shared on this system
so that each member of the team has easy access to group information.

3 Research
In the engineering Industry or any other industry, every project undertaken by any
organisation requires a level of professionalism that is relevant to the industry. The main
method of ensuring that high standards of professionalism are employed in company
projects is to carry out relevant research before the project is set in motion in order to avoid
epic failures that lead to catastrophe, loss of money, and loss of market share.
3.1
Market Research
Market Research is a systematic, objective collection and analysis of data about a particular
target market, competition, and environment.
The purpose of any market research project is to achieve an increased understanding of the
subject matter. With markets throughout the world becoming increasingly more
competitive, market research is now on the agenda of many organisations, whether they
are large or small. (Definition of Market Research, 2005-2011)
3.1.1 Market Analysis
To fully understand the targeted market and to efficiently meet customer requirements,
suggestions and complaints from clients have been analysed and evaluated. Additionally,
detailed research on the project, industries and companies related to the subject has been

Low-cost design
From investigations so far completed, it is possible to confirm there is a market for the
offered system. Consequently, G6 Tidal Solutions will release further production of the
system as the demand grows. Therefore, the market can be defined as a Bull Market.
A Bull Market is defined as a
financial market of a group of securities in which prices are
rising or are expected to rise. The term "bull market" is most often used to refer to the stock
market, but can be applied to anything that is traded, such as bonds, currencies and
commodities. (Bull Market, 2011)
3.1.3 Target Market
The target market of the business is small to medium sized businesses and educational
institutions around the United Kingdom that are particularly interested in Marine
Engineering and Management solutions. The company will work on a basis of submitting
proposals in response to requests by potential customers. Necessary research will also be
carried out for potential customers to ensure that the organisation builds relations with
customers that share similar business interests and policies with G6 Tidal Solutions.
3.1.4 Existing Customers
The University of Greenwich is the first client of the organisation although the clientele base
is predicted to grow as the company begins to be known and recognised by other
organisations in the Marine Industry.
3.2
Customer Requirements
Customer requirements for any project or product show detail of the customer’s
expectations from the particular product, usually in their own words. The customer
requirement information is sourced through inquiry and person to person interview with
the customer in question. The customer requirements usually, but not in all cases have
primary (very important), secondary (not so important) and secondary (can be done
8/10/2019 419 Instrument
http://slidepdf.com/reader/full/419-instrument 21/126
Tidal Test Tank Project Page | 21
without) requirements that has to be met by any service provider or product designer as the
case may be.
In some cases like a project, there may be multiple customers to make use of the same final
product. In such cases, retrieving the customer requirements is more tedious as multiple
customers are involved. This is where it becomes very important to identify the
stakeholders for the project at hand.
3.2.1 Stakeholders
The stakeholders of a project are the people that are of interest in the project; these are the
people who are affected by the main decisions made with regards to a project. The
following lists the project stakeholders identified by brainstorming
Mr Rodney Beams
Mr Peter Snelling
Students
Mr Bruce Hassan
Mr Vic Cosgrove
Mr Ian Cakebread
Dr Malcolm Butler
Professor Ndy Ekere
Commercial Port Operator
Other Technical staff
Other Universities
Local Community
These listed stakeholders were classified in their order of importance and direct
involvement with the final product. See classification schematic below of the stakeholders
8/10/2019 419 Instrument

Tidal Test Tank Project Page | 22
Figure 4: Tidal Test Tank Project Stakeholders
The stakeholders of a project can lead to identifying the parties that have the highest
influence where the design of a product is concerned in a situation where there are multiple
customers. It is therefore important to note that “all the customers of the project are
stakeholders, but not all stake holders are customers”.
Figure 5: Customer and Stakeholder Relationship
This shows a relationship /link between the stakeholders and customers of a particular
project. The broken line shows that not all stakeholders are customers; while on the otherhand, all the project customers are stakeholders. In this project, the stakeholders who were
8/10/2019 419 Instrument
http://slidepdf.com/reader/full/419-instrument 23/126
Tidal Test Tank Project Page | 23
not considered to be customers were mostly the tertiary stakeholders. This simple
relationship and the classified stakeholders, helped in identifying the parties whose primary
requirements were priority.
3.2.2 Stakeholder Requirements
The selected stakeholders from the above classification, who were perceived to be
customers of the project, were then interviewed to obtain individual requirements that
translated into stakeholder requirements. The selected stakeholders that were interviewed
include:
Mr Rodney Beams (Main Project Client)
Mr Peter Snelling (Client Representative)
Mr Bruce Hassan (Technician)
Mr Ian Cakebread (Technical Manager)
End User (Students)
Figure 6: Stakeholder Requirements

Tidal Test Tank Project Page | 24
Customer requirements can finally be drawn from the above requirements stated by each
stakeholder/customer.
3.3
Final Customer Requirements
This was done by selecting any requirements common to all the listed stakeholders, and
then taking requirements of more important customers into consideration. Please see listed
customer requirements below, not necessarily in order of importance
Test tank should be a cheap, cost effective solution
Must be simple and easy to use / operate
The tank should be capable of performing simple tidal test
Tank should be capable of simulating the tidal behaviour of another river or marine
environment
Safe for all users to operate (very important )
Easy to set up for testing
Safe location and safe working height
Reliable, durable and requires less maintenance
Capable of being self maintained
Should be physically accessible for users
The tank should have a long life span (at least 25 years)
Should provide accurate and reliable test results to users (especially students)
The diagram below is a summary of the process of determining customer requirements.
Figure 7: Flow Diagram for Determination of Customer Requirements
These customer requirements listed above are the backbone on which the project/product
design is made and completed, as the customer has to be satisfied in the listed ways. It is
important to note that the customer requirements listed could be further classified into
groups in order of importance from primary to tertiary. It should also be noted that not all
8/10/2019 419 Instrument
http://slidepdf.com/reader/full/419-instrument 25/126

the requirements were supplied by the customer as they may not know what they want
sometimes, but know what they do not want.
3.4
Product Life Cycle
The product life cycle (PLC) of a product is the life path of the product from conception to
disposal. When a new product is conceived and introduced into the market, it goes through
a stage concept development where no profit is made as the product is not yet released to
the market. It then goes through a stage of research and development where customer
surveys and prototype development. Again, at this stage, no sales have been made yet, thus
the product is still not yet profitable. When the product has been proved to work and
relevant market research has been carried out, the product is then introduced to the
market. At the level, customers are neither familiar nor loyal to the product.
The product’s life continues into the growth stage where it begins to gain reputation and
customer loyalty. This results in increased sales volume of the product. The maturity of the
product in the market begins when the product has a good reputation and continues to see
constant sales volume. After spending some time in maturity, the product starts to see a
decline in the sales volume as a result of age, lack of improvement and even market
saturation.
Improvements to products and new market strategies at intervals when the product
experiences some decline, can increase the life span of the product. After complete decline
of the product it can be disposed appropriately. The producer can begin to change its
facilities so that it begins to produce alternative products. This pattern of product life cycle
is general for all products and can be configured to suite special situations.
The life of a product experiences changes in the marketing situation, and maybe the sales
outcome of the product as a whole may be declined. When this happens, the manufacturers
have to device a means to increase the sales volume of the product back to an acceptable
level even if not as much as the previous sales volume before the decline.

Figure 8: Product Life Cycle Diagram Invalid source specified.
The Tidal Test Tank is a one off product, but experiences the same life cycle as any other
product would, from inception, to decline and disposal. The life cycle can be suited to the
status of the test tank as a special case. Below is a schematic of the tidal test tank PLC
Figure 9:Tidal Test Tank Product Life Cycle Diagram
The sales axis of the tidal tank is represented by the product’s functions in the above
schematic. The test tank will be contracted out to the company; hence the customer for the
product is already available. This means that the product does not have to go into the
market for sale after the design and manufacture. Interestingly, in the concept and designstage, the product sees no sale (functions) as the product is not yet realised. The
8/10/2019 419 Instrument
http://slidepdf.com/reader/full/419-instrument 27/126
Tidal Test Tank Project Page | 27
introduction stage is represented by the testing and maximising the tank’s operational
functions. This involves testing the different systems that make up the product, and then
making needed adjustment so that the product is used at its optimum operation conditions.
The introductory testing stage passes and ushers in the product multiple functions provided
by the product in its operational life. This stage sees the increased functions of the product
and it represents the growth and maturity stage of the test tank. After some time of being
used, the factors of age, wear and tear on components start to show as the components of
the system start to break down. Most common examples of this include corrosion which can
further lead to failure of the critical components such as pumps and valves. This
phenomenon therefore reduces the functionality of the test tank, and marks the onset of
the product decline.
The decline of the test tank can be delayed by carrying out major service as indicated at set
intervals, or even component change, for example changing pumps every 2 or 3 years. It is
however important to note that, the service and change carried out on the tank would not
restore it to its initial level of operational functionality, as indicated on the PLC diagram
above. The decline stage can then be allowed to fully set in when the expected operational
life (about 25 years) of the product has been fulfilled or when the product becomes
redundant.
The disposal of the product after its service is very important and marks the end of the PLC.
Disposing of the tank system involves firstly assessing the extent of disposal that has to be
done. When this is completed, the components of the tank that could still be useful for
other purposes are identified and dismantled off the main system. The rest of the system
can then be dismantled, with the recyclable parts sent off for recycling and the non
recyclable parts disposed off appropriately.

3.5
Medway River Research
The purpose of the tidal test tank is to be able to mimic the tide characteristics of the
Medway River. The first step towards being able to simulate the Medway River tides was to
find out the tide behaviour of the river. The Medway river average tidal range is known to
be 5.7m (East, 2007). A study of free tide charts indicated that the highest tides in Chatham
can reach heights of 6.65m at high spring tides. (Admiralty, 2011)
Another factor to be considered is the type of water that flows in the Medway River. In
order to design as tank that holds a close resemblance to the Medway River, it is important
to also know the condition of the water that flows in the river. It would be easy to assume
that the river Medway contains fresh water. However, because it is a tidal river, it has a back
flow of sea water. This water is saltier than fresh water, however less salty than sea water.
This is known as brackish water. The water in the river becomes more salty in the direction
of the sea. The concentration of salt in sea water is an average of about 35g of salt per litre
of sea water. Brackish water ranges from 5g to 30g of salt per litre of water. (Crest, 2010)
3.5.1 Types of Ports
It has not been stated what kind of port for which the tidal test tank will be used to test port
operations. Thus it made sense to research on the types of ports that exist. There are 3
types of ports. The first is known as a closed port. An example is Medway port. This is a port
where by basins are created that are accessed by ships through locks. The water in this type
of port is kept at a constant level. As a result, the port operations within the basins are not
affected by the rise and fall of the tide. However, the ships are scheduled to go in and out of
the port depending on the tides; if the tide is too low then the ships have to wait for it to
rise again before they can leave or enter the port.
The second type of port is known as a open port. An example of an open port is Sheerness.
The water level in the port rises and falls with the tide. This means that ships have a limited
amount of time to load and unload.
8/10/2019 419 Instrument
http://slidepdf.com/reader/full/419-instrument 29/126
Tidal Test Tank Project Page | 29
The third type of port is known as a dry port. This is a type of port that is used for ship
maintenance amongst other port operations. This type of port is known as a dry dock
because the basin where the ship s contained has the water in it fully drained when the
ships are being handled.

3.5.2 Typical Test tank facilities
The different tests that a towing tank is used for tests on ship models. Such tests include
resistance tests, cavitation tests, propulsion tests and open water test amongst other tests
that can be carried out on scaled down models of ships. The most common tanks are towing
tanks that are much bigger that is required in this project. As a result it was necessary to
deviate from the normal type of towing tank designs.

4 Product Analysis
In order for any designer to be able to design a product that is required by his client, it is
important for an analysis of the product to be carried out. Such an analysis enables the
designer to identify any constraints that need to be overcome in order for the product to
have certain attributes required by the client. A designer is thus able to identify the tools
needed for a solution to be formulated with regards to satisfying customer requirements.
4.1 Functional Analysis
A product function is defined as the normal actions that are performed by the particular
device or product (WebFinance Inc, 2011). Where the tidal test tank is concerned, the
product functions would be what the tasks the tank is expected to perform and any other
functions that may come as a by-product of having the tidal test tank. An obvious function
of the tidal test tank is “tidal testing”, which could be regarded as a primary funct ion of the
product. All other functions that the tank can satisfy that are not as important as the
primary function can be considered to be secondary and tertiary functions.
On another hand, functionality is the ability for a product to perform a particular task or
function (Farlex Inc, 2011). This implies that the functional analysis of a product not only
shows the intended and possible functions of the product, but also the expected ability of
performing the named product functions.
The above named function is however not all the possible functions of the tidal tank, hence
the tank functional analysis shows all the functions of the tidal tank, both intended and
possible and also its expected capabilities in a hierarchical order of importance. The product
function analysis was obtained through interaction with the customers and by
brainstorming within the group. The functional data in table 3 was a result of the analysis
carried out.

In the above functional analysis also show functional requirements of the tidal test tank
product. The hierarchy of classification is as follows
Primary Functions: The functions of the product that are basic/necessary to its
operation.
Secondary Functions: These are not basic to the operation of the product, but are
however desired by the user with relatively less significant importance compared
with the primary requirements.
Tertiary Functions: These are desired functions that hold the least importance. They
can only be achieved when all the primary and secondary functional requirementshave been achieved.
4.2
Customer Attributes to Product Characteristics Conversion Analysis
The customer attributes are expectations of the customer in terms of requirements from
the product of interest. These attributes cannot be quantified or measured as they are
desires; hence the service provider has to determine a way to relate to the attributes. On
the other hand, characteristics are the physical properties of the product that can be
8/10/2019 419 Instrument
http://slidepdf.com/reader/full/419-instrument 34/126
Tidal Test Tank Project Page | 34
quantified/measured and therefore controlled. These then enable the designer to set limits
for the design so that the customer attributes are provided.
CUSTOMER ATTRIBUTES PRODUCT CHARACTERSITCS

5 The Solution
The product developed to be designed is a tidal test tank aimed as simulating the tidal
motion of the Medway River. The tank also has the capabilities of simulating tidal
movement of other Port environments around the world. This product will be designed to
be mostly automatic and simple to operate and use. The automated parts of the system
limit the amount of manual control by the test tank operator, making the system safe.
Different system parameters are specified in this chapter, some of which are driven by
customer requirements and also government policy. The set parameters will then be used
to design a product that satisfies the customer and the stakeholders.
5.1
The Different Solutions
After having set all the parameters that were to be designed for, a number of solutions were
formulated in order to create a test tank system capable of satisfying all basic customer
requirements. Brain storming is the main tool that was used to determine the way in which
each requirement was to be satisfied. Following brainstorming, different solution design
solution ideas were generated and were then considered one after another. The most viable
idea at a time was chosen and critically examined including the feasibility and realisation of
the solution.
This method of generation the solution to the tank design problem helped the group have
multiple design ideas that could be employed with minimal modifications as the problem
solution. When the likely design was chosen by the group, unfolding developments at the
time forced the group to review and modify the design to suite the situation, solving the
problem or eliminating it completely. After this stage and all design integrity have been met,
the design was finalised as the group’s solution to the tidal test tank project. In summary,
the design solution involved the following steps in sequence
Generate Design Ideas – Consider Ideas – Choose Design – Review Design – Finalise Design
8/10/2019 419 Instrument
http://slidepdf.com/reader/full/419-instrument 36/126
Tidal Test Tank Project Page | 36
5.1.1 Tide Simulation
In order to be able to simulate the tide movements, it was determined that the tidal test
tank would need to have a reservoir that would contain the volume of water required to
produce the rise and fall of water level in the tidal test tank. This was the main concept
around which most of the detail of the design was based on.
The next consideration was the duration of the testing times. The tide in the river rises and
falls every 6 hours. It would be very time consuming to carry out tests on a real time basis.
Also, the users of the tank, the university students, would use the testing facility during a
laboratory session. The laboratory sessions at the university last for 2 hours. It would thus
make sense to simulate a tide rise/ fall in 2 hours. Water level in the test tank would change
from high to low, or low to high in a 2 hour laboratory session.
5.1.2 Water Level Control
Having reservoir means that a means of moving water between the test tank and the
reservoir is needed. The two tanks would be arranged so that the reservoir can be at high
level, and gravity could be used to move the water from the reservoir to the test tank. A
pump would thus be used to pump water back to the reservoir. This method was not
adopted as it provided no means of a controlled flow rate of water from the reservoir to the
test tank. The flow rate of water would be highest when the reservoir is full, and then
reduce as the water level in the reservoir drops. As a result, this arrangement was not used.
5.1.3
Salinity Control
It was considered to have a dosing unit for the test tank in order to make brackish water for
the tidal test tank. The dosing unit would have a concentrated solution of brine and then be
used to make the required concentrations of brackish water in the test tank. Water
becomes saturated with salt at about at concentration slightly higher than sea water levels.
With a dosing unit at this concentration, the dosing unit would need to have a mixing tank
that is about the same size at the test tank. Consequently, this was not to be pursued for the
test tank on account of the system becoming complicated and unnecessarily costly.

Tidal Test Tank Project Page | 37
5.1.4 Temperature Control
A temperature range is required for the tidal testing facility. This is 0oC to 40oC. There are
many ways in which water can have heat added to it or removed from it. The most viable
solutions formulated for this were the use of electrical heating elements to heat the water,
and to use a chiller to cool the water.
5.1.5 Test Tank Dimensions
As mentioned earlier in the report, most test tank facilities that exist tend to be very large.
In this case, research revealed that only one ship model needs to be tested at a time during
any laboratory sessions. The largest model is about 2m long. The tidal test tank needs to be
able to accommodate such a model, so its’ length is to be no less than 2.5m.

Quality Function Deployment
The quality function deployment (QFD) is a visual decision making tool which shows how
existing and proposed solutions for a certain application are matched with customer
requirements (WebFinance Inc, 2011). It transforms the customer requirements into design
quality which can be used to deploy functions to meet that stated design quality. The QFD
matrix is also known as the House of Quality (HOQ Matrix) and is comprised of various
rooms interacting with each other to make up the entire house.
The rooms are Customer Requirements: this is where customer requirements are represented in
their own words.
Planning Matrix: this room shows how existing products including this company’s
product fairs with the named customer requirements.
Technical Requirements: this room is also known as the engineering characteristics.
The information here is developed by the design team who identify the measurable
characteristics of the product that are related to meeting the customer
requirements.
Interrelationships: this is the main body if the HOQ matrix and it identifies the
relationship between the customer requirements and the technical requirements.
Roof: this identifies the areas where the technical requirements that characterise the
product support or impedes one another.
Targets: this is the last room in the HOQ matrix and it summarises the data
contained in the other rooms and final design targets.

Figure 13: Tidal test Tank QFD Matrix
Having identified QFD as a viable quality tool, the group decided to carry out a QFD analysis.
The illustration in figure 14 is the result of the QFD analysis carried out by the group to
check the quality and integrity of the design. Have such a QFD analysis, the group can
determine the acceptance of the product by providing customers with what they require,
hence avoiding failure.
As a summary, the group took careful solution steps in a systematic sequential order to
achieve the optimum solution to the problem at hand. See the schematic below for a
summary of the solution tools used by the group to achieve the final solution

Quality Assurance Management System
In order to develop a quality product, the company has established an effective quality
management system. The foundation of a quality organisation is the concept of the
customer and supplier working together for their mutual benefits; consequently the
customer-supplier interfaces are extended into and outside the organisation.
Quality Management System will help to direct and control the business in order to
continually improve the effectiveness and efficiency of its performance.
Thanks to this system two basic requirements will be met:
Customer’s requirements: confidence in the ability of the organisation to deliver the
desired design and service consistently meeting their needs and expectations
Organisation’s requirements: efficient use of the available resources at an optimum
cost
Quality Management Systems are used in all sectors of the business and it will:
Set direction and meet customer’s expectations
Improve process control
Reduce time and wastage
Lower costs
Increase market share (QUALITY MANAGEMENT SYSTEM (QMS) STANDARD, 2011)
5.3.1 Standards
The following standards will be used to monitor the quality of the product and service:
ISO 9000: 2000 – Quality Management Systems – Fundamentals and Vocabulary
ISO 9001: 2000 – Quality Management Systems – Requirements
ISO 9004: 2000 – Guidelines for Performance Improvement
ISO 1400 – Environment Management Standard (Summers, 2000)
8/10/2019 419 Instrument
http://slidepdf.com/reader/full/419-instrument 43/126
Tidal Test Tank Project Page | 43
These standards are built around business processes, with a strong emphasis on
improvement and a focus on meeting the needs of the customers. In fact, the family of ISO
9000 contains eight quality management principles, upon which to base an efficient,
effective, and adaptable QMS, which are applicable throughout industry, commerce and
service sectors:
Customer Focus
Leadership
Involving People
Process Approach
Systems Approach
Continual Improvement
Factual Decision Making
Mutually Beneficial Supplier Relationships (Quality Management Systems, 2011)
5.3.2 Ergonomics
The Company in order to develop a quality design has followed these standards:
ISO 7250: 1996 Basic Human Body Measurement for technological design
ISO/TR 16071: 2003 Ergonomics of Human System Interaction- Guidance on
Accessibility for human-computer interfaces
ISO/TR 16982: 2002 Ergonomics of Human System Interaction- Usability methods

Process Flow Design
Figure 18: The path taken by water in the system
8/10/2019 419 Instrument
http://slidepdf.com/reader/full/419-instrument 49/126
Tidal Test Tank Project Page | 42
The Process flow design illustrates the path taken by the water when it is moved for the
tidal simulations.
On initial set up, the main test tank will be filled to the High Water Level from the mains in
order to provide the full volume of water required in the system which is about 3000 litres.
Water from the test tank will be fed to the reservoir by means of gravity through an
actuated control valve. The control valve will limit the flow rate to required amounts. The
reservoir is only large enough to hold the required movable water to create tide simulations
in the tide testing facility. The volume of movable water needed for tidal rise and fall in the
test tank is 1800 litres. This amounts to a low and high level of 0.2 m and 1 m respectively.
When the reservoir contains water at the High Water Level (HWL) mark (0.45m), the test
tank is at Low Water Level (LWL) (0.2m), which is the lowest water level allowed in the test
tank. When water in the test tank is at the HWL mark, then the reservoir is at its LWL mark.
From the reservoir, water is moved by a single phase pump at full speed through a flow
reducing throttle valve. At this point, any excess water from the pump is sent back to the
reservoir, and the required flow rate is sent directly to the test tank. Alternatively, water can
be fed to the test tank via the chiller when the water needs to be chilled.
When water reaches the LWL in the reservoir, a switch is triggered in the reservoir that
stops the pump, preventing overflow in the test tank and potential damage to the pump.
This means that the test tank is full and the test tank is at HWL. At this level, the actuated
valve at the test tank outlet can then be opened so that it begins to feed water back to the
reservoir. Then when water reaches LWL in the test tank, the actuated valve is commanded
to shut fully.
When the water reaches the HWL in the reservoir, a switch is triggered that will start the
pump so that it feeds water to the test tank. This means that the system can run tide cycles
automatically whilst the user carries out measurements. The automatic cycles range from 2
hours to 6 hours depending on the set flow rates for the experiments. The flow rates can be
set on the Labview PC.

Control system Design
The test tank is designed to simulate tidal characteristics in real and scaled time as
required. Also to be controlled by the test tank are the water salinity, water temperature
and water flow rate. These requirements necessitated the design of a control system to
monitor and control the named parameters. In the process of designing this control system,
different control techniques came up and were briefly investigated to choose the best
option. They are
Mechanical Control: This involves the use of mechanical instruments to monitor andcontrol the said parameters. For example, using a hydrometer to measure the
salinity of the water.
Instrumentation: This involves the use of electronic instruments that have been pre-
programmed to measure and possibly control certain quantities.
Electronic Programmable Circuits: Sensing instruments are employed and controlled
using self programmed electronic circuits.
Figure 19: Control Technique Comparison

Tidal Test Tank Project Page | 45
6.3.1 Control System
The schematic above was used as a comparison tool between the three control techniques.
Instrumentation was chosen to be used in the control system design. This meant that
sensors and similar instruments to measure control the stated quantities had to be selected
in the process of designing the control system
Figure 20: Control System Design Process (Dorf & Bishop, 2005)
The above design process was followed to select the necessary instrumentation in the
process of designing the control system. The goal of the control system, was to achieve a
fully or semi automatic control of certain quantities. The important quantities to monitor
and control were
Water Temperature
Water Salinity
Water Level
Water Flow Rate
8/10/2019 419 Instrument
http://slidepdf.com/reader/full/419-instrument 53/126
Tidal Test Tank Project Page | 46
The listed quantities can be monitored and controlled using electronic instruments and
sensors. The sensors can only be selected by carefully determining the requirements it has
to meet in terms of performance, dimensions, protection against adverse conditions etc.
These considerations were used to write up a specification for the level control sensor.
PARAMETER VALUE UNIT REASONS
LIQUID SENSED SALT AND/OR FRESH
WATER
The test tank would normally contain salt or fresh
water which is the working fluid of the system
LEVEL RANGE TO
DETECT
0 – 1.2 m The transducer must measure water levels up to 1.2
m above the minimum (i.e. zero level). The
maximum water level in the tank is 1 m, hencehaving more level measurement capacity will check
for overflow
ACCURACY CLASS ±0.5 %FS Sometimes referred to as tolerance. The output
must be within a small percentage of the full scale
value
OPERATING
TEMPERATURE
RANGE
0 - 40oC The transducer should be capable of working in
fairly diverse temperatures. The test tank can be
used to simulate any particular marine region/area
at any weather
SPECIFIC GRAVITY
AT MAXTEMPERATURE
1.02 Dimensionless ratio of the density of the fluid
compared to a standard density. This value varieswith temperature and could affect suspended
particles
RATED OUTPUT ±5 VDC The output of the transducer should be a
reasonable DC voltage signal to allow for accurate
measurement
RESOLUTION 0.05 m The transducer must be capable of measuring small
level changes of at least 0.05 m, to have more
sampled level data and accuracy
SUPPLY VOLTAGE 5 – 15 VDC Transducers usually require excitation voltage to
operate
MAXIMUM MASS 0.75 Kg Low mass is a desired if the sensor will be placed in
the tank. There would be no distortion of results
OUTPUT
INTERFACE
USB USB serial connection to computer software should
be available. The software will assist in level
monitoring, control and data recording
CONTROL PROGRAMMABLE The sensor should be capable of being programmed
further to aide with overall system control and data
manipulation
PROTECTION CLASS IP58 Minimum The transducer must be protected against salt and
other particles. It should also be protected from
continuous immersion in water
Table 7: Level Transducer Specification
8/10/2019 419 Instrument
http://slidepdf.com/reader/full/419-instrument 54/126
Tidal Test Tank Project Page | 47
The specification was used to search for suitable level transducers for the control system.
Two transducers were identified and reviewed
1. Flowline Inc’s Echopod which uses ultrasonic means of sensing, to switch and
control the level as desired
2. Honeywell Limited’s LLE Series optical sensor, which uses infrared technology to
sense and transmit result to the controller
The two transducers were reviewed and the Honeywell optical level sensor was chosen for
the control system. Some of its features include
Small size, thereby needing less space
Digital output
Microprocessor compatible, hence programmable
Pre-wired
The above specification writing and selection method was implemented for the other
sensors and instruments and equipment used in the control system. A list of the selected
instruments and equipments can be found later in this report. The instrumentation
schematic in figure 19 shows the interaction between the sensors in the system
The chiller is shown independent on the schematic as it will not be automatically controlled
from the PC interface like the other sensors and equipment. The sensors in the control
system are to be strategically placed inside or outside the test tank as required by their
function. The measured parameters are sent back to the PC interface via hardware USBinterface. The Labview PC software interface will be used on the control panel to monitor
and control and output and inputs of the sensors in the system.

Electrical Systems Products and Design
An electrical system plays a significant role in the tidal test tank system. Several electrical
components have been selected based on the main supply voltage. A single phase 240V/ac
is set out as a main supply. On the basis of this restriction the components have been
selected to meet the requirements.
6.4.1 System Requirements
Control Panel: The control Panel is mainly used for the purpose of controlling the
system as a whole. Therefore the control panel will need to have several
characteristic and parameters.

Tidal Test Tank Project Page | 52
Transformers: A transformer is used to step down the voltage to the required output
voltage for several components within the system, due to their operating voltage
characteristics.
Voltage Regulator AC to DC: Several components are operating at a lower voltage
than specified, therefore AC to DC conversion will be required in order for the
components to operate accordingly
Wiring Cables: Different types of electrical wiring cables are used depending on the
components operating parameters. The length and diameter each cable will changebased on the operating voltage and current of each component.
Relay Switch: The relay switch is used as a circuit break from the main control panel.
5 relay circuit breakers will be required to protect the component from overload or
short circuit.
6.4.2 Electrical System Design
A design has been carried out based on the system requirements. As shown in Figure 12 the
control panel consists of 5 relay circuit breaker to protect all the components used.
Primarily one relay will be used to operate the water level sensor, temperature sensor, and
flow sensor because their operating voltage falls between 4.5 -12V/DC. Hence a transformer
is utilised to step down the voltage from 240V AC – 50V AC. Additionally, because the
sensors are operating on DC characteristics, a voltage regulator is required for the
conversion of AC to DC. The pumping system will use one relay circuit breaker given that it is
operating at 230V AC at 3.3A. Furthermore, the pumping system will have its own
Emergency Stop Push Button (ESPB) in case of a malfunction in the pumping system.
Other components such as water heater, Digital thermostat, and water chiller will have their
individual relay circuit breakers. These components will not require transformer or voltage
regulator since they are operating above 230V AC.

Moreover the value readings from the water heater, Digital Thermostat, water level sensor,
temperature sensor, and flow sensor are ought to be interfaced to a PC using a standard
USB cable.

7 Manufacturing Plan
The time and cost of manufacturing systems is affected by the uniqueness of the components that
it comprises of. G6 Tidal Solutions proposes a design that consists mainly of standard components.
This means that the test tank, the reservoir, sensors, and all other parts of the testing facility can be
purchased “off the shelf” from various suppliers. This then gives the advantage of reduced lead
times and also guarantees that components can be sourced and easily replaced once the testing
facility becomes operational.
Detailed plans have been made by the company to manage the time and cost effectively. A Gantt
chart showing the time estimation for project implementation and realisation if given the chance in
the way of a contract by the client is shown below
Figure 24: Project Implementation Gantt Chart (Time Estimation)
The above chart shows a total of 70 working days the company estimates for completion of the
project if given the contract by the client. This translates to 4 months and 2 weeks to finish up the
project and have the product running and ready for the customer. It is important to note that this
8/10/2019 419 Instrument
http://slidepdf.com/reader/full/419-instrument 63/126
Tidal Test Tank Project Page | 56
time given is only an estimate and should be treated as such as other factors like public holidays,
supply chain difficulties, labour work difficulties and similar problems can prolong the stated time
to deliver the final product to the customer.
Also detailed below is a network analysis of the tasks required to realise the project for the client as
desired. This was derived from the estimate Gantt chart above

9.3
Electrical Health and Safety
Working with electrical equipment is made safe by carrying out suitable checks, such as inspection
or testing on all electrical equipment and components to ensure that they are in suitable working
condition. The level of inspection or testing should depend upon the risks. It is hazardous for to
work within areas with unprotected live wires.
The most common hazards that occur with electrical equipment or installation are as follows:
1. Poor maintenance of electrical equipment
2. Exposure to mains electricity supplies where UK currently supplies 240volts
3. Incorrect use of electrical equipment in potentially explosive areas
4. Poor electrical installations and faulty electric appliances are often the root cause fire
accident.
5. Avoiding of any contact with live parts causing shock and burns
6. Fixed electrical installations should be inspected and tested by a competent person at least
every three years.
7.
A test certificate confirming the date and results of the inspection and test should beprepared and displayed at all time.
8. Precautions against the risks caused by flammable or explosive hazards, electrical
equipment.
9. Electrical shock hazards: All persons should not touch electrical controls in a tank area, such
as a pump power, electrical switch; when standing on a wet floor as this can be fatal.
The client is recommended to take necessary measures to avoid such hazards and
any life threatening hazards related to working with electricity that may not be
mentioned in this document.

10 Services
A good consultancy company provides solutions for its clients either by designing new products or
by designing modifications to the client’s already existing equipment. An excellent consultancy
company continues relations with customers after implementing solutions by recommending
methods of best practice as well as good maintenance plans. G6 Tidal Solutions offers this service
to all its clients.
10.1
Maintenance Program
G6 Tidal Solutions an organization that is committed to provide an excellent maintenance service by
providing prompt responses to problems faced by customers. As shown in the Product Life cycle, all
equipment starts to deteriorate with time and use. It is therefore necessary to be able to
recommend maintenance programmes that would enable the product’s lifespan to be lengthened.
That way, the client is able to use the equipment as long as possible.
10.2
Tank Maintenance
The main tank is made of 40% glass fibre ABS material. This material has good resistance to
chemical attack; however it is not immune to degradation caused by:
Visible light
Ozone and other extraneous pollutants
Intrinsic manufacturing impurities
Oxygen
Heat
Consequently deterioration-fighting chemicals are added to the material during the manufacturing
of the product. Moreover to extend the life span of the product, dirt and grime can be cleaned with
distilled or deionised water and strains can be removed with a non-ionic detergent. It is advisable to
avoid using solvents, as the material is likely to have a strong reaction to the solvent leading to
cracking to the product. (Restoring plastic based items, 2011)
It is also important to check for leaks periodically. The tank is made up of separate panels. Although
a sealant is used within the joints, leaks may be experienced in areas where the sealant is not
8/10/2019 419 Instrument
http://slidepdf.com/reader/full/419-instrument 78/126
Tidal Test Tank Project Page | 71
evenly distributed, or simply where the sealant has failed. Another area to regularly check for
leakages is in joints where the tank is joined to pipes and instruments (Brown, 2011). The test tank
will be containing salt, so it would be advisable to rinse out the tank with fresh water when it is fullydrained to avoid a build up of salt crystals on the walls of the tank.
10.3
Reservoir Maintenance
The reservoir is made of the same material as the tidal test tank. It would then have the same
maintenance routine as the tidal test tank. The reservoir would require occasional freshwater
rinsing to remove salt crystals. A routine check for leaks can be coincided with that of the Tidal test
tank. Focus should be made on the joints and connection for pipes and instruments.
Cracks and other signs of fatigue can be checked for every 3 years. It is important to do this as the
tank experiences cyclic loading by the pressure exerted on its walls due to the rise and fall of water
level.
10.4
Components Maintenance
Every system is as robust as its weakest component. It is therefore important to recognise that
practicing the best methods of operation includes carrying out the relevant and necessary routine
and long term maintenance procedures for the various parts that make the entire system.
10.4.1 Sensors
These can be considered to be consumables. This means that they can be replaced when they cease
to perform their required function.
8/10/2019 419 Instrument
http://slidepdf.com/reader/full/419-instrument 79/126
Tidal Test Tank Project Page | 72
10.4.2 Pump
The pump is one of the key components of the system, thus it is of great importance to keep it well
maintained. It is recommended to flush it with fresh water when it completes its service with saline
water. This will prevent the collection of salt crystals in the pump, and lengthen its lifespan. The
pump is a component that will not have the same lifespan as the tank. Consequently, every time a
main overhaul is carried out, the pump may have to be replaced, depending on its condition at the
time when the planned maintenance occurs.
10.4.3 Valves, Pipes and Fittings
The valves and pipes can be subject to clogging due to scale built up. It is recommended to de-scale
them at set intervals of the year in order to maintain high system performance.
10.5
Platform Maintenance
The platform will be used by people. It is therefore recommended that the platform be inspected
on a monthly basis to ensure that it is intact for health and safety reasons. Inspected platforms
should be tagged accordingly to ensure that they do not fail when they are in service.
10.6
Breakdown
The Tidal Testing facility has been designed in a way that avoids complete system breakdown. Each
part of the system can be independently dismantled. This enables maintenance to be carried out on
specific areas of the testing facility without disassembling the entire system.
10.7 Recommended Planned Maintenance Schedule
During the operational phase, Tidal Test Tank is recommended to be overhauled every 3 years for
inspection and repairs of any components demonstrating reduced performance.
Machinery maintenance takes place periodically when the tidal test tank is in operation. Important
environmental aspect to take under consideration is:
Discharges
Waste Management and treatment
Noise and dust emission

11 Environmental Impact and Consideration
Designing waste disposal facilities that meet the environmental rules and regulations is a complex
task because of the large number of factors that influence waste. As a result, customers are
becoming mindful of the way in which their operations affect the environment. An Environmental
Impact Assessment is required for any project that is likely alter the environment significantly.
Planning authorities require the developer to produce an environmental statement including.
A description of the development and data on the main impact it is likely to have on
the environment
A description of the likely significant environmental impacts including direct and
indirect impacts
Impact on human beings
Impact on landscape and cultural heritage
Reduce
Reuse
Recycle
Responsible
Disposal
Figure 29 :"Reduce, Reuse, and Recycle" Waste management (the 2e element)
11.1 What are the overall impacts on the environment from the project?
The project may have some significant impacts on the environment due to the use of excessive salt
water which needs to be disposed at least once every six month. In addition at the end of the
materials product’s life cycle and how it is disposed may play a significant role on the environment.

Tidal Test Tank Project Page | 74
11.2
Trade effluent
Trade effluent is any liquid waste that is discharged from premises being used for a business, trade
or industries. This project in particular has considered two methods of disposing systems due to
the involvement of relatively large amount of salt water effluent involved. On the one hand, salt
water can be disposed of via waste disposing companies. A contract can be made with companies
to collect and dispose salt water on regular intervals of the year. A potential company that would
be suitable for this purpose is Envirogreen. On the other hand, salt water can be disposed of using
the mains sewerage system. However this option requires certain regulations to be obeyed by the
company or the user responsible for discharging trade effluent to a foul sewer. These are explored
later in the report. Some of the factors of concern where large volumes of salt water are being
disposed of in the sewerage are:
Damaging the sewers
Damaging the sewer treatment works
Cause a health hazard for sewerage workers or the general public
Harm the environment
11.2.1 Water Pollution Regulations
It is important to be aware of the effect of water pollution when disposing salt water. It can be
considered as a substance which capable of entering surface waters or groundwater. The following
legislations have been used as a guide to the way in which G6 Tidal Solutions recommends for salt
water disposal.
The Anti-pollution Works Regulations 1999 water resources, England and Wales No. 1006
The control of pollution ( Applications, Appeals and registers) regulations 1996
The Hazardous Waste Regulations 2005 (which implement the provisions of the European
Hazardous Waste Directive 91/689/EEC) provides a consistent definition of Hazardous
Waste and ensures environmentally sound management and regulation of such waste.
8/10/2019 419 Instrument
http://slidepdf.com/reader/full/419-instrument 82/126
Tidal Test Tank Project Page | 75
11.2.2 Saltwater Disposal
Several investigations have been made to find a solution for the problems outlined above. Hence it
is important that the company or the user complies with the restrictions regardless of how much
trade effluent is been discharged. Hence there needs to be a trade effluent agreement with the
local water and Sewerage Company before discharging any trade effluent to the sewer.
Disposing salt water via waste disposing companies will depend upon the user’s location, how the
chemical is contained as well as the type of chemical that needs to be disposed. In this case, the
effluent is 3000l of brackish water, with a potential maximum concentration that reaches seawater
levels. From the research carried out it has been concluded that to collect and dispose of hazardous
wastes, there is a minimum collection charge of £320.00 including VAT (Envirogreen).
Having listed out the environmental problems and solutions previously, it is important to outline
the responsibilities of the general user of the product as follows
Notification and registration to relevant authorities
Selection and approval of specialist contractors for the disposal of Hazardous Waste
Provision of advice to Schools and Departments regarding classification of Waste Schools
and Departments are responsible for
Ensuring they have systems for risk assessment, identification, and suitable packaging
available for the management of Hazardous Waste
Monitoring that staff, students and contractors are following the necessary systems Staff,
students and contractors are responsible for
Staff contractors who generate hazardous waste are responsible for ensuring that it is
packaged properly

Tidal Test Tank Project Page | 76
11.3
Disposing Tank Materials
According to the product life cycle the tank and any other component parts related to the tank will
be dismantled and disposed of, or reused for other purposes.
11.3.1 Reusing Components in the System
Once the product has fulfilled its purpose, some of the components may need to be reused for
suitable applications. The following components could possibly be reused depending on their
operating conditions and the state they are in when the product has reach the end of its estimated
lifespan.
Pump
Sensors
Pipes PVC material
GFRP reservoir
There are some advantages in that some components, such as the sensors, have no direct contact
with the salt water hence the likelihood of damaging them is low compared to the pump. The pumpis exposed to the salt water during laboratorial operations. Also the effects of salt water on PVC and
stainless steel materials are insignificant.
Figure 30 End-of-life FRP Components
As mentioned above some components may need to be reused on the bases of their functionality.
However when recycling or disposing large amounts of materials some legislation may need to be
8/10/2019 419 Instrument
http://slidepdf.com/reader/full/419-instrument 84/126
Tidal Test Tank Project Page | 77
considered. As the waste Framework Directive requires that the waste to be classified by the type
and the purpose of its use, Generic Fibre Reinforced Polymer (GFRP) waste can be classified under
several codes of the EU waste list as follows
Frame work Directives (75/442/EEC) in 1975
Additional related document including 91/156/EEC
European waste list (commission Decision) 2000/532/EEC
11.3.2 Complete Disposal of the System
Alternatively, if there is no usable application for the components in the system, complete disposal
is the only remaining option. There are different regulations and requirements for the disposal of
materials such as GFRP, pipes, fittings and valves, and for the disposal of electrical components
such as pumps and sensors and the PC.
The estimated cost for incineration of GFRP is £120 to £150 per tonne (National Composites
Network). Other components in the system

APPENDIX 5 – SALT WATERCREATION

http://slidepdf.com/reader/full/419-instrument 106/126
Tidal Test Tank Project Page | 99
Water Salinity
The Medway River contains brackish water as mentioned before. The salt content in the
water consists of a wide variety of salts and not just sodium chloride. As a result, it has been
decided that marine salt can be used in order to provide the Medway Estuary conditions.
The salt content in brackish water ranges from 5g of salt per litre of fresh water, to 30g of
salt per litre of fresh water. However, to allow for more flexibility of testing conditions,
calculations have been made so that the salinity in the tank can range from fresh water
conditions to sea water conditions.
Instructions for making the salt water in required concentrations from fresh water
1. Ensure entire system empty (test tank, pipe work and reservoir)
2. Make sure all valves to and from the test tank are closed
3. Half fill the tidal test tank ( to the 1500litre mark) with fresh water from the mains
source
4. Raise water temperature to about room temperature.
5. Add the required salt i.e. 5kg to 105kg of salt. Do not handle more than 25kg of salt
at a time.
6. Evenly distribute the salt in the tank to avoid creating a lump of salt collecting one
section of the tank
7. Allow the salt to dissolve till the water is saturated
8. Add the remaining fresh water in intervals, allowing the salt to mix in the water
9.
Fill the tank to the 3000litre mark
10. Check if salt is completely dissolved then distribute the water to the reservoir.
Low Concentration to High Concentration salinity
Example, if concentration is at 10g/l then 30 kg of salt is already in the water, to increase
salinity to 25g/l, simply add a further 45kg of salt to the water in the test tank and allow it to
dissolve

Suppliers
This is a table of possible suppliers that can be used for the supply of bulk sea salt. If the
same supplier is used on a regular basis, then a contract can be set up in order to reduce the
cost of the salt per unit mass.
Salt Supplier Cost Contact
Kent Reef Salt Coventry Aquatics £1.90 per Kg Tel: (024) 7650 3050
Instant Marine Salt 123 Aquatics £2.00 per Kg Tel: (017) 3346 8677
Sea Salt Summer Naturals £0.90 per Kg Tel:(016) 1338 2256
Red Sea salt Amazon £1.97 per Kg Amazon.co.uk
Caution:
Health and Safety regulations;
o Do not lift more than 25kg of salt at a time.
Allow salt to fully dissolve in the test tank before distributing water through the
piping and pump system to avoid moving solid salt particles.
Note: Evaporation of water from the test tank due to warm conditions in the testing
environment can lead to higher concentrations of salt water as the water evaporates into
the atmosphere.
