Damen Shipyards offers unique mobile ballast water treatment system

Damen’s InvaSave Mobile Ballast Water Discharge Technology is an alternative to retrofitting vessels that only needs to treat the ballast water on discharge.

The system which can be delivered in a container can be based in a port and transported to vessel that needs to treat its ballast water prior to discharge. InvaSave 300 container unit handles 300 cu m per hour, and it is easy to scale up by using multiple container units.

“We have been looking for what we can do to help our customers regarding ballast water treatment and finding alternatives for those owners who may not want to retrofit a ballast water treatment system, perhaps because their ships operate on fixed routes or their ships are too old and make the investment in a system prohibitively expensive,” said Gert jan Oude Egberink, Damen manager for ballast water treatment.

All vessels that ply international routes even shorthaul ferries will have to comply with the ballast water management convention when it comes into force.

The system could also be provided by ports as a back-up for shipboard systems if they fail.
