TECHNOLOGY BALLAST WATER<br />

TANKER<br />

<strong>Operator</strong><br />

Missing procedures almost in place<br />

Centres prepare to deliver type testing certification for ballast water treatment systems, discovers Brian Warshaw.<br />

As previous articles in <strong>Tanker</strong><strong>Operator</strong><br />

have demonstrated, there is no lack<br />

of conceptual designs for the treatment<br />

of ballast water, in order to remove or<br />

to render harmless invasive sea-borne<br />

species of organisms and pathogens.<br />

Chemical, mechanical and physical<br />

equipment and processes have been built,<br />

operated and evaluated; but for these to<br />

become endorsed for service on vessels<br />

operating internationally, two pieces of<br />

the procedure have been missing. First<br />

has been an internationally defined test<br />

outcome, and second, recognised facilities<br />

where the tests could be undertaken.<br />

The first of these, a standardised test<br />

outcome was resolved in July last year,<br />

when the IMO's Marine Environmental<br />

Protection Committee (MEPC) agreed to<br />

Resolution MEPC 123 during its 53rd session.<br />

Under the general heading of<br />

'Guidelines for Ballast Water Management<br />

Equivalent Compliance (G3)', Annexes 3<br />

and 4 provided the missing information.<br />

Annex 4, 'Guidelines for the Approval<br />

of Ballast Water Management Systems<br />

(G8)', provided the procedure for the<br />

administration of designated bodies<br />

which will assess whether ballast water<br />

treatment systems meet the requirement<br />

of Regulation D-2 of the convention governing<br />

the control and management of<br />

ships' ballast water and sediment. The<br />

document also gave guidance to manufacturers<br />

and shipowners as to how equipment<br />

should be constructed, controlled<br />

and monitored.<br />

Testing will have to take<br />

place at both land-based<br />

facilities and at sea. If the<br />

system is successful in meeting<br />

the targets, the administration<br />

will issue a type<br />

approval certificate relating<br />

specifically to the system<br />

tested. Land-based testing of<br />

the ballast water management<br />

system (BWMS) can be<br />

undertaken at a laboratory,<br />

an equipment factory or a<br />

pilot plant, including a<br />

moored barge, or on a test<br />

ship. The G8 guidelines provide<br />

details of the pre-evaluation<br />

documentation<br />

required from the manufacturer,<br />

the test and performance<br />

specification, the<br />

requirements for the environmental<br />

evaluation, and<br />

the analytical methods to be<br />

used to determine the biological<br />

constituents in the<br />

discharged ballast water.<br />

For the sea-trials, a fullscale<br />

BWMS must be<br />

installed on the vessel undergoing<br />

testing. Under certain<br />

criteria, the G8 document has<br />

indicated that the equipment<br />

used for land-based testing<br />

could be scaled in size.<br />

For those systems that use an active<br />

substance, that is one that uses an organism,<br />

including a virus or fungus that acts<br />

against harmful aquatic organisms and<br />

pathogens, Annex 4, 'Procedure for<br />

Approval of BWMS that make use of<br />

Active Substances (G9)', also received<br />

approval. This provides similar information<br />

to that of G8, but relates also to the<br />

storage, handling and testing of the active<br />

substances.<br />

For some time, a programme to construct<br />

suitable testing centres has been<br />

ongoing, especially in the US. Towards<br />

the end of 2001, the US Coast Guard,<br />

together with the Environmental<br />

Protection Agency (EPA), asked for privately<br />

owned test and research facilities<br />

that could participate in testing ship ballast<br />

water treatment (BWT) technologies.<br />

The two organisations have agreed to cooperate<br />

in using the environmental technology<br />

verification (ETV) programme to<br />

assess the performance level of BWMS<br />

that are commercially available.<br />

The programme was looking for facilities<br />

that could provide a natural body of<br />

marine or fresh water, which included<br />

natural assemblages of organisms sufficiently<br />

large to permit sample collection<br />

and system operation, together with a<br />

pump delivery and discharge system.<br />

Flow temperature, pressure and sample<br />

monitoring were required, as were sample<br />

holding tanks, and a water tank that could<br />

Introducing the 5100 Marine Portable Gas Analyser<br />

to allow for offloading ballast water from<br />

Approved to the latest electrical and mechanical hazardous area safety <strong>standards</strong> the new unit replaces the trusted<br />

OA 262 oxygen analyser. With ease of operation designed in right from the start, operations such as<br />

gas freeing can now be made even safer.<br />

Based on the same non-consumable paramagnetic technology used in our 1800MV inert gas<br />

system analysers and 1900MV vapour control system analysers, you can depend on<br />

it being ready for use whenever you need it.<br />
