Dutch InvaSave ballast water treatment passes tests on German ship
DUTCH shipyard unit Damen Green Solutions has completed tests of its InvaSave ballast water management system (BWMS) from ballast water from the 800-TEU Henrike Schepers, owned by Germany's HS Schiffahrts, but operated by Iceland's Samskip.
InvaSave is designed as a port-based treatment alternative to shipboard systems and to be mounted ashore or on a barge, reports London's Marine Propulsion & Auxiliary Machinery.
It still needs the same type-approvals as conventional ship ballast water management systems though it has completed its land-based tests last year.
For the shipboard tests, said the report, ballast water was taken in untreated and the system's effectiveness was checked as it treated the water during discharge.
Tests showed that it met IMO's D2 standard, Damen Green Solutions, said in a statement. This included a test series conducted with the high-sediment waters of the River Hull and the River Thames in the UK.
All testing was conducted by the Marine Eco Analytics testing organisation in the Netherlands, which had also carried out the land-based tests.
"These tests have shown that the InvaSave is capable of providing an IMO type-approved back-up in a port in the event of a failure in a vessel's on board treatment systems, " the company's statement said.
Damen Green Solutions, a subsidiary of Damen Shipyards Group (1927), of Groningen, expects to obtain approval from the UN's International Maritime Organisation (IMO) by the end of the year.
