Damen Shipyards’ containerised ballast water management system InvaSave performed its first commercial treatment last week (25 April), the company announced yesterday (3 May).

It was carried out by a barge-mounted system for Royal Wagenborg’s 14,000 dwt newbuilding, the open top multipurpose ice-classed Egbert Wagenborg and appears to have taken place before the ship was formally handed over: the ship’s operator has reported a delivery date of 28 April and a maiden voyage on 30 April.

Egbert Wagenborg was brought alongside a quay in the harbour of Delfzijl and Eemshaven and the barge carrying the InvaSave 300 was positioned ahead of it. Ship-to-ship operator MariFlex – which is providing the treatment service – connected the vessel to the InvaSave using a 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.

Anneke Schäfer, director of nature and environment at Federation Groningen, started the equipment and made a speech welcoming its arrival. Spectators included representatives from port operators and authorities, shipowners and other maritime organisations.

Philip Rabe, responsible for InvaSave sales at Damen, commented in the company’s statement that it is delighted the system “is finally operational in a commercial environment.”

The unit is now available for use in the harbour for vessels either without their own BWMS or with malfunctioning equipment. MariFlex plans to have a second unit operational in Rotterdam before IMO’s Ballast Water Management Convention comes into force on 8 September.
