Damen’s InvaSave external ballast water treatment system has received IMO type approval

Damen’s InvaSave external ballast water treatment system which is designed primarily for use in ports and harbours has received IMO type approval.

The Damen InvaSave treats ballast water to the IMO D-2 standard, for ballast water received from inbound ships. It can also deliver water treated to the same standard to outbound vessels. Its mobile, containerised format means that it can be operated from the dockside or from onboard a vessel alongside, receiving or delivering water to a ship.

Marcel Karsijns, managing director of Damen Green Solutions, said: “InvaSave solves the ballast water challenge in ports. We are very proud to receive IMO type approval – it proves the capabilities of this product, something that we have believed in for a long time now. We are looking forward to providing this solution to the market.”

Damen InvaSave is a single-pass system and uses mechanical filtration and ultraviolet radiation to remove and eradicate invasive organisms, and has been tested in fresh, brackish and marine water, including coastal water with a high sediment load.

The system is designed to be able to treat water with a low turbidity and a UV Transmission of down to 20%.

The InvaSave’s application goes well beyond the relevance it has for ports too. In many cases, it offers vessel owners a viable and cost-effective alternative to retrofit. And, in the event of failure in an on-board system, it ensures that owners have a means by which to access water treatment quickly, without downtime.

After the 8 September 2017, unmanaged ballast water is not allowed to be discharged by law. Any vessel that cannot take in or discharge its ballast water after that date will be restricted in its operations and there may be financial implications due to demurrage costs.

Damen has dedicated years of research on the development of the InvaSave, including collaboration with some of the leading research institutes in the Netherlands - Groningen Seaports, Wagenborg, MariFlex and Waddenfonds.
