Ballast Water Convention

Case Study

Challenge


Vedam


The introduction of harmful aquatic organisms and pathogens to new environments, including via ships„ ballast water, has been identified as one of the four greatest threats to the world„s oceans

- Secretary General, IMO, 2003


Vedam


In Feb 2004, IMO adopted an

INTERNATIONAL CONVENTION FOR THE CONTROL AND MANAGEMENT OF SHIPS' BALLAST WATER AND SEDIMENTS

(commonly known as “Ballast Water Convention”)

Objective – to regulate

discharges of ballast water and

reduce the risk of introducing non-

native species from ships’ ballast

water.


Vedam


Applicable to all vessel types operating in aquatic environment which are designed to carry ballast water & are entitled to fly the flag of a Party to the convention

Regulates the discharge of BW either by BW exchange (Reg.D1) or by treating ballast water to meet certain standard (Reg.D2) by gradual implementation of convention depending on ships‟ build date and quantity of ballast carried on-board.

Convention also issued Guidelines – G1 to G14

The requirement of TREATMENT comes from Reg D2.


Vedam


Organism Category Regulation

Plankton, >50 μm in minimum dimension

< 10 cells / m3

Plankton, 10-50 μm < 10 cells / ml

Toxicogenic Vibrio cholera (O1 and O139)

< 1 cfu* / 100 ml or less than 1cfu /g (wet weight)

Escherichia coli < 250 cfu* / 100 ml

Intestinal Enterococci < 100 cfu* / 100 ml

Sets standard for the Treatment systems to comply

Treatment Systems must be tested and approved in acc

with IMO Guidelines - G8 (&G9 if active substance used)


Vedam


USCG has proposed a regulation to be implemented in two phases: ◦ Phase 1 same as IMO-D2.

◦ Phase 2 is around 1000 times stringent

applicable for ships built after 2016,

Ships built before 2016 should comply first docking or Five (5) years after phase 1 implementation (greater)

Practicality review is proposed in 2013 to evaluate availability of technology to achieve set standards.

Multi Location Installation

Deciding Factors –

availability of space

installation accessibility

Minimum modifications (structural, piping, electrical)



Vedam


Machinery Spaces

• Access for maintenance

• Additional ventilation for storage of chemicals

Pump Room • Explosion proof systems

Exposed Deck • Explosion proof systems in case of tankers

• Increase in GT if enclosed compartment added

In Situ pipe fabrication & installation

◦ Less engineering required

◦ High chances of rework for clash removals

◦ High Wastage of material & time

◦ High down time for ship

Manual measurement onboard, 3D Routing & pre-fab ◦ Less down time of ship

◦ Pipes fabricated at workshop – good quality

◦ Large amount of engineering time spent onboard for measurement

3D Laser Scan, 3D Routing & pre-fab ◦ Less time spent onboard

Methodology


Vedam


At docking/Quay side ◦ Ship offhire for the period of retrofit

◦ Must in case of in situ fabrication (hot work) & installation

During sailing/operation ◦ Pipe can be pre-farbciated using Pre-fabrication drawings from 3D model

◦ Installation can be done during operation (cold fitting) with least interferance in normal operation

Execution


Vedam


Class Approvals

◦ Approvals for Retrofit Drawings

◦ Coordination for Class survey onboard

Workshop Coordination

◦ Technical Specification for retrofit

◦ Job work order & Workshop Selection

Supervision

◦ Quality inspections (critical for in-situ fabrication)

◦ Workshop inspections for pre-fab pipes

Feasibility & Costing

◦ 32,000 Bulk Carrier

◦ Ballast Pumps - 2x700 CuM/hr Pumps,

◦ Ballast Capacity - Total 12,000 CuM

◦ Equipment with different treatment methods analysed

◦ Capex ranges from Aprox 800,000 To 1.3M USD

◦ Annual Expense ranges from 7,000 To 25,000 USD


Vedam


Total 60,000 Ships required to be retrofitted in a short period of time.

All existing ships must start retrofitting by 2015.

The price of equipment have drastically reduced in last two years. However, this may see reverse trend post ratification.

Sudden Demand for retrofits :

◦ Equipment - High Cost / High Lead time / Non Availability

◦ Long Class approval Time

◦ Premiun Engineering Hrs
