Damen Green Solutions’ InvaSave technology is nearing International Maritime Organization (IMO) Type Approval.
Results thus far have shown that it can provide IMO Type Approved backup in the event of a ship’s onboard ballast water treatment systems (BWTS) failing to uptake or discharge ballast water.
The InvaSave technology, which uses UV filtration without any chemicals, can also serve as a port-based alternative for ship owners that have not retrofitted their ships with an on-board ballast water treatment system (BWTS) or in the case a ship is deployed in a port with a sudden outbreak of marine invasive species.
The results of the InvaSave testing shows that the technology can meet the IMO’s D2 standard. The test series included high sediment waters of the River Hull and River Thames, UK. All testing was conducted by Marine Eco Analytics, Netherlands.
The system can be delivered in a self-sufficient mobile container for flexible placement in a service barge or for movement around the port on a trailer or a pontoon.
The technology is available at Groningen Seaports, Netherlands, which is the first port to provide this ballast water treatment service. Other ports that operate in sensitive areas, such as World Heritage Sites and Particularly Sensitive Sea Areas.
Damen Green Solutions’ Product Manager Matthijs Schuiten commented: “More and more countries are ratifying the IMO’s Ballast Water Management Convention (BWMC) and it could enter into force in 2017; in any case, it is only a matter of time. Damen is cooperating with the service providers in the ports to provide this ballast water treatment service. This is also relevant for all port authorities, who could face congestion problems if they don’t have a contingency/emergency service in place.”
Following the successful shipboard tests, IMO Type Approval is expected to be obtained later in 2016 with a current patent pending.
