Ballast Water Treatment – Retrofitting Challenge

– Akshay Jain


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

BW Convention


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”)

BW Convention

Objective – to regulate discharges of ballast water and reduce the risk of introducing non-native species from ships’ ballast water.


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.

BWC - Summary


Organism Category Regulation

Plankton, >50 μm in minimumdimension

< 10 cells / m3

Plankton, 10-50 μm < 10 cells / ml

Toxicogenic Vibrio cholera (O1and O139)

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

Escherichia coli < 250 cfu* / 100 ml

Intestinal Enterococci < 100 cfu* / 100 ml

BWC – Regulation D2

Sets standard for the Treatment systems to comply

Treatment Systems must be tested and approved in accordance with IMO Guidelines - G8 (&G9 if active substance used)


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.

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

BWT - InstallationMethodology


At docking/Quay side◦ Ship off-hire for the period of retrofit◦ Must in case of in situ fabrication (hot work) & installation

During sailing/operation◦ Pipe can be pre-fabricated using Pre-fabrication drawings from 3D model◦ Installation can be done during operation (cold fitting) with least

interference in normal operation

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 approx 800,000 To 1.3M USD◦ Annual Expense ranges from 7,000 To 25,000 USD



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◦ Premium Engineering Hrs
