OceanSaver becomes the first electro-chlorination BWMS system to be type approved by the US Coast Guard

The US Coast Guard (USCG) has granted its second and third ballast water management system (BWMS) type approvals, to Alfa Laval and OceanSaver.

On 23 December the agency announced that Alfa Laval’s PureBallast 3 system and OceanSaver’s BWTS MKII had been granted certification.

OceanSaver’s electro-chlorination (EC) system, with treatment capacities from 200-7,200m3/h, is the first EC system to be granted approval. The manufacturer claims the EC method is more suitable for medium and large vessels – including LR1 tankers, VLCCs and large gas carriers – than ultraviolet (UV) light treatment.

Alan Linderoth, vice president sales & marketing, OceanSaver, said: “The OceanSaver system is a perfect match for medium to large vessels, meaning that owners now have USCG certified systems available for small, medium and large vessels. It is also promising to hear that other makers are in the process of obtaining the USCG type approval.”

The US Coast Guard noted that its approval only covers the 300m3/h and 1,000m3/h variants of the Alfa Laval UV reactor – although these reactors can be used in series or parallel to treat larger flow rates up to 3,000m3/h. “Future approval of the 170 and 600 reactors is dependent on Coast Guard approval of the UV reactor scaling studies, which are currently under review by the Marine Safety Center,” the agency said.

The approvals follow the granting of the first USCG type approval for BWMS to Optimarin on 2 December.
