Ballast treatment via containerised ballast water management systems are now available at 10 north European ports, according to a statement this week (20 December) from Netherlands-based Damen Shipyards Group.

Damen Group members Damen Green Solutions (DGS) and Damen Shiprepair & Conversion (DSC) have cooperated to provide ballast water reception and bunkering services using Damen’s InvaSave system in Rotterdam, Amsterdam, Brest, Dunkerque, Vlissingen, Den Helder, Stellendam and Harlingen. These are in addition to two Dutch ports served under a different arrangement.

DGS is in talks with several other ports and harbour service providers around the world to offer the InvaSave service, the statement said, quoting DGS sales manager Philip Rabe, who said the company’s goal “is to build up a reliable worldwide ballast water service network.”

As examples of vessels that would find the service useful, he mentioned those that need salt water to make free chlorine, which will not always be able to function in freshwater ports such as Amsterdam, he said. Unmanned barges that cannot perform mandatory ballast water exchanges would also benefit, he suggested.

This arrangement is not related to a deal made in December 2016 between DGS and MariFlex. BWTT reported that development in January and it became the year’s most-read news item.

At the time, the proposal was to provide InvaSave services in all Dutch ports and in April 2017, it led to Groningen Seaports commissioning an InvaSave 300 port-based ballast water treatment system to serve the ports of Delfzijl and Eesmhaven, making them the first harbours in the world to offer a commercial IMO-certified ship-to-ship ballast treatment service.

One pre-delivery demonstration on a newbuilding was described as the service’s commercial debut in late April but no other commercial customers have since used the service. In the future, “we believe that the number of customers will increase in line with the enforcement of the ballast water regulations,” the Damen Group told BWTT today (22 December).

MariFlex still offers that service in those ports but its plan to have a second service operating in Rotterdam by the time the Ballast Water Management Convention came into force in September did not come about. That port is now part of this latest initiative.

BWTT has asked Damen when this DSC/DGS service became available at the various ports and will update this item in due course.
