CHAPTER ONE

1.0 INTRODUCTION

1.1 THE SIWES

The Engineering discipline is practical in nature and mainly hinged on experience.

Hence there is great need for any student aspiring to be a professional engineer to

have some form of work experience while studying at school, in a reputable

engineering firm related to his/her course of study.

Students Industrial Work Experience Scheme (SIWES) is in accordance with the

federal government policy of technical education to enable students to be exposed to

the working experience in industries and to enable them to be useful to their

employers practically and not theoretically alone.

The Students’ Industrial Work Experience Scheme (SIWES) gives students the

opportunity to gain some relevant experience before leaving the campus. The

experience gotten by the students during the SIWES program would enable them

quickly fit into the industry upon graduation.

I had my work experience at the National Engineering and Technical Company

Limited (NETCO), a subsidiary of NNPC, and an indigenous engineering firm. At

NETCO, I learnt the fundamentals of electrical engineering; computer aided electrical

design, AutoCAD, and other relevant softwares such as Plant design management

system (a 3D drafting software), Chalmlite (a lighting design software). My day to

day activities at NETCO were recorded in the log book.

1

1.2 AIM

The Students’ Industrial Work Experience Scheme (SIWES) is aimed at giving

students the opportunity to have work experience and practically apply the theoretical

concepts learnt in the University. It is also aimed at widening the mental and creative

horizon of the students.

CHAPTER TWO

2.0 SIWES WORKPLACE (NETCO’s Profile)

Description of SIWES workplace:

NAME: NATIONAL ENGINEERING AND TECHNICAL COMPANY

LIMITED (NETCO)

ADDRESS: Stallion House. 2, Ajose Adeogun Street, Victoria Island, Lagos.

2.1 NETCO’s HISTORY

National Engineering and Technical Company Limited (NETCO) is Nigeria’s premier

indigenous engineering company. It is a fully owned subsidiary of the Nigerian

National Petroleum Corporation (NNPC), providing efficient and reliable engineering

base for the NNPC group and the entire oil and gas industry.

It was established in 1989 as a joint venture between the Nigerian National Petroleum

Corporation (NNPC), and Bechtel Incorporated of USA, a world renowned

engineering company as its technical partner.

Under the joint venture agreement, the NNPC maintained 60% shareholding while

Bechtel held 40%. Commercial business started in August 1990.

However, in December 1996, Bechtel exercised its options under the shareholder’s

agreement and formally pulled out of the Joint venture and subsequently sold its

equity share to the NNPC. NETCO thus became a fully owned subsidiary of the

NNPC from May 1, 1997.

NETCO’s motivation, drive and target are embedded in its vision and mission

statements thus:

Vision

“To be a world class Engineering Company.”

Mission

“To provide world class engineering services in the oil and gas industry.”

3

Quality Policy

“To satisfy and strive to exceed customer requirements through continuous

demonstration of quality and active participation of all employees”.

With the exit of Bechtel, potential and regular clients became sceptical with regards to

doing business with NETCO. In order to change the situation, NETCO decided to

retool, re-package and re-launch itself. To attain the retooling was a decision to

pursue and obtain the ISO 9001 Quality Certification. The re-launch took place during

the 1st Quarter of 1998 and it was very successful. Once again the clients were

confident in NETCO. Subsequently, NETCO executed many major engineering

projects amongst which were: - The Shell’s Cawthorne Channel Gas injection/supply

Project in consortium with Technip Geoproduction of France, detailed Engineering

design of the condensate stabilization unit of the NLNG Expansion Project. NETCO

which had generally been recording operational losses, started to record profits. In

May 2000, Bureau Veritas Quality International (BVQI) successfully audited and

subsequently awarded NETCO the prestigious ISO 9001 Quality Certificate. This

achievement is the first by any indigenous engineering company in Nigeria.

NETCO is managed by Nigerian engineers who have been trained locally and abroad

on live projects and in all engineering disciplines.

It is fully equipped to provide its services in all areas of the Oil & Gas industry.

CHAPTER THREE

3.0 PROJECT EXECUTION IN NETCO

3.1 PROJECT INITIALIZATION

NETCO’s business starts in the Business Development department when it receives

invitations from prospective clients to submit competitive bids for executing projects.

Relevant departments meet to decide whether the decision is worthwhile. A project

manager is appointed to coordinate the preparation of the bid. This usually involves

most of the departments. Finally, the Business Development department submits the

proposal and follows it up.

If the bid is successful, NETCO management appoints from various departments a

Project Manager and other personnel that will form the project team.

The Project Manager maintains a harmonious relationship with the client and ensures

that his personnel have the right facilities and a conducive working environment to

execute the project.

The Finance and Accounts department prepares invoices and collects payments from

clients. This helps to maintain a positive cashflow and to ensure that funds are

available for the payment of wages and other corporate expenses.

A typical project team usually comprises mainly of personnel from the Engineering

department.

3.2 THE ENGINEERING DEPARTMENT

The Engineering department is the ‘engine room’ of NETCO’s operations. The

department is directly involved in the execution of jobs and on whose shoulders the

responsibility of meeting client’s specification, quality, work procedure, standards and

schedule rests.

The department is divided into discipline groups. A manager, who reports to the

Executive Director Operations, is Head of the Engineering Department. The role of

the department is fulfilled by a team of Engineers of the various discipline groups. An

Engineer who is more knowledgeable in the activities of the group leads each of the

10

discipline groups. The lead discipline Engineers report to the Engineering manager

on issues regarding project execution and coordination of the groups’ activities.

Figure 2 shows the organizational structure for the Engineering department.

CHAPTER FIVE

5.0 SKILLS AND PRACTICES ACQUIRED AS AN INDUSTRIAL TRAINEE

As a student under the SIWES at NETCO, I was exposed to standard Engineering

design practices. The projects executed at NETCO ensured that Engineers worked

in teams, hence, I was taught to be a team player, and a good one at that.

I received training in the following areas of electrical engineering practice:

1. Computation of Load list:

This is one of the starting point for the electrical group activities. For any given

project, it is important to know the specific number of electrical loads on site. This

is to ensure adequate sizing of power sources, cables, distribution boards etc. I

learnt how to compute a load list, which is usually a Microsoft Excel document

showing all intended loads, their tag numbers, current, voltage and power ratings,

efficiencies, power factors, and service duty.

Table 1 below shows a sample load list which I developed for a given offshore

platform.

Table 1: Load List for an Offshore Platform.

2. Generation of single line diagrams:

There were many instances where I was required to develop one or single line

diagrams. The electrical load list came in very handy in such instances. A single

line diagram is a schematic drawing that uses graphical symbols and standard

nomenclature to illustrate the overall configuration of an electrical system. The

single line diagram shows diagrammatically the conceptual/detailed design for

power generation and distribution on a site, interconnections between various

19

loads, Generation philosophies, load layouts, busbars and their respective voltage

levels, system protection devices, amongst others. These are well shown on single

line diagrams with standard electrical symbols. I received extensive training on

the use of autoCAD, which is the software used by the electrical group to draw

one line diagrams. Figure 3 below shows the single line diagram which I drew

with the aid of autoCAD for the offshore platform whose load summary is shown

in Table 1.

20

Fig.3 – Single line digram for the Offshore Platform.

3. Equipment sizing and Cable sizing:

Areas covered here includes Generator sizing, Transformer sizing, circuit breaker

sizing, and cable sizing calculations. I also learnt about the relevant standards and

codes as regards equipment sizing and cable selection, such as the National

Electric Code (NEC), and the National Electric Manucfacturers

Association(NEMA) codes.

As part of my training, I was given an assignment on equipment and cable sizing

in the Bechtel project. The calculations I carried out are shown below:

4. Electrical Layout drawings (Earthing, Cable, and Lighting layout):

An electrical layout drawing gives a plan view of an area (e.g a flowstation), and

shows by means of appropriate sign conventions, such features as the earthing

grid(earthing layout), electrical cable route(cable routing layout), location of

lighting towers/fixtures(lighting layout) etc. I was trained on how to draw layout

drawings using autoCAD. I learnt about the various factors to be considered

before layout drawings/designs are produced.

5. Hazardous Area classification/drawings:

I was also trained on how to produce hazardous area drawings using autoCAD. A

hazardous area is a three-dimensional space in which a flammable atmosphere

may be expected to be present at such frequencies as requires special precautions

for the construction and use of all electrical apparatus.

The purpose of these drawings is to provide assistance in selecting the correct

certified equipment for hazardous zones (as will be clearly noted on the drawing)

such as petrochemical plants, refineries, gas plants, oil terminals, etc.

6. Supplementary drawings (Cable schedules, Distribution board schedules,

Schematics and Interconnection drawings, Installation details,

Specifications):

These drawings are also produced at later electrical design stages for a project. I

was also opportuned to see how these drawings were produced and their relevance

to the project.

The training I received involved the use of the following computer aided

design/application softwares:

AutoCAD

Chalmlite ( a software for lighting design and calculations).

Plant design Management system (PDMS).

27

AutoCAD

It is a computer aided drawing software. It is used by the electrical group to draw

single line diagrams, electrical layout drawings, hazardous area drawings, distribution

board schedules, schematics and interconnection diagrams, power layouts etc.

The AutoCAD design package is a general purpose software. It is an extremely

powerful tool. The speed and ease at which a drawing can be prepared and modified

using a computer offers a phenomenal advantage over hand preparation. There is

virtually no limit to the kind of drawings that can be prepared using the software.

AutoCAD provides a set of entities for use in constructing a drawing. An entity is a

drawing element such as a line, circle, or text string annotations. The effect of every

change appears immediately, thus enabling the designer to take immediate decisions

concerning size, aesthetics and taste of the designer.

Other AutoCAD functions allow modifications of the drawing in a variety of ways

e.g. erasing or moving entities or copying them from repeated patterns. The view of

the drawing displayed on the screen can be changed, or information about the drawing

can be displayed. The use of layers and assigning colours to the different layers

enhances the appearance of the end product and aids in detecting errors in the drawing

that would otherwise have gone undetected. The final drawing can then be plotted

with a pen plotter or printer plotter.

The importance of this software can be more appreciated in that is saves time and cost

in the production of drawings, by providing the engineer with a mature tool to work,

thus, ensuring a more professional and accurate output.

The activities of the electrical group to which to which I was attached, involved the

extensive use of autoCAD.

28

Chalmlite:

It is a computer aided lighting design software. It is used by the electrical group to

carry out lighting design/calculations (general lighting, fence lighting, interior lighting

etc). With the aid of this software, an area could be lit to any required illumination

level, with appropriate fixtures/lighting towers positioned at appropriate locations.

Illumination levels at various locations are automatically calculated and displayed.

Design specifications such as maintenance factor, mounting height, aiming point, type

of fixtures, etc are usually supplied by the client. Design is thus based on client

specifications, with allowance made for suggestions to the client from the electrical

group.

The activities of the electrical group to which to which I was attached, also involved

the extensive use of chalmlite.

The lighting calculation results as computed by the Chalmlite Lighting Design

Program indicating the illumination level at different points in the defined

area(Tuomo flowstation) and target grid summaries are as shown below as Fig 4 and

Table 3 respectively. The lighting towers are shown on the figure as FT-1 to FT-17

respectively. This design is for general lighting of the area under consideration.

Plant Design Management System (PDMS)

This is an advanced drafting software. Three dimensional models can be made with

the aid of this software. This software is more versatile than autoCAD as far a 3-D

work is concerned. Some of the applications of PDMS are routing a sequence of cable

34

trays and piping components, structural designs, HVAC design, and lighting design. I

received basic training in the use of PDMS.

5.0.1 SKILLS ACQUIRED

By virtue of the training I received and exposure, I have acquired the following skills

from the SIWES workplace (i.e. NETCO):

Proficiency in the use of AutoCAD.

Proficiency in the use of Microsoft EXCEL for the development of spreadsheets.

Ability to use chalmlite to carry out lighting design and calculations.

Ability to use Plant design Management System (PDMS) – a 3D drafting

software.

Ability to work effectively in a team, and to communicate effectively with others.

CHAPTER SIX

6.0 CONCLUSION

35

The SIWES has positively contributed to my training as a future Electrical/Electronics

Engineer. At the SIWES workplace (i.e. NETCO), I was able to reconcile theoretical

principles learnt in school with real Electrical/Electronics engineering design practice.

I also learnt various software applications relating to my discipline such as AutoCAD,

Plant Design Management System(PDMS), Chalmlite, Microsoft EXCEL, Microsoft

Word, etc. Furthermore, I received extensive training on electrical design

fundamentals which included the following: Development of load and single line

diagrams, Design of electrical layout drawings(cable, earthing and lighting layout

drawings), Hazardous area classification drawings, Equipment sizing, cable and

circuit breaker sizing, preparation of material take-off and bill of quantities, lighting

design/calculations, and schematic/interconnection drawings.

SIWES gave me the opportunity to learn about good work ethics, good interpersonal

and communication skills.
