DNV type approval for ballast water treatment system
DNV has issued its first type approval certificate for a ballast water treatment system.
The system has been developed by Alfa Laval.
Together with Alfa Laval and the Norwegian Institute for Water Research (NIVA), DNV oversaw intensive tests to ensure that the product is ready for installation on board ships.
IMO has adopted a new Ballast Water Convention that is expected to come into force in the next few years after the required number of ratifications has been achieved.
Once the convention has been ratified, systems to prevent the spread of organisms through ballast water will be mandatory. In a transition period different systems for exchanging the ballast water will be accepted, but ballast treatment systems will be required to be installed from 2012 - 2016, dependent of ship size and age.
The type approval certificate has been issued on behalf of the Norwegian Maritime Administration and confirms compliance with MEPC.125(53) and MEPC.126(53)
