'MV Egbert Wagenborg' discharged its ballast water to the containerised InvaSave 300 on the quayside

Damen’s award-winning and IMO certified InvaSave ballast water management system (BWMS) has gone into commercial operation following a public demonstration at Groningen Seaports in The Netherlands.

The launch marks the culmination of a seven-year programme to develop an effective mobile BWMS for use in ports.

Philip Rabe, InvaSave sales at Damen, said: “We’re delighted that the Damen InvaSave is finally operational in a commercial environment. It is a unique product and, in many cases, it enables ports to offer vessel owners a viable and cost-effective alternative to retrofitting on-board systems.”

He added that the system also comes into its own in the event of failure of an onboard system. It allows ports to offer owners a means by which they can access ballast water treatment at short notice, ensuring minimal downtime.

At the demonstration, the newly launched MV Egbert Wagenborg was brought alongside a quay and the containerised InvaSave 300 mounted on a barge in front of the bow.

Ship-to-ship operator MariFlex then quickly connected the vessel and InvaSave using a convenient standard hose connection. The ballast water was then pumped out of the ship and passed through the InvaSave for treatment before being released into the harbour.

The IMO-approved Damen InvaSave has been designed primarily for use in ports. The system receives ballast water from inbound vessels and treats it to IMO D-2 standard to eliminate potentially invasive marine micro-organisms. 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.

Damen's new unit is now ready for operations at the harbour of Delfzijl and Eemshaven for vessels either without, or with malfunctioning, onboard BWTS capability. MariFlex also plans to have a second operational in Rotterdam ahead of the September implementation of the IMO Ballast Water Management Convention.
