The Norwegian company OceanSaver has received the final type approval certificate for its Ballast Water Treatment System (BWTS) from the US Coast Guard (USCG).

This means that a USCG type approved system is now available for medium and large vessels like LR1s, VLCCs, and large ga[ds_preview]s carriers the company stated.

US regulations require all vessels trading in US waters to treat their ballast water with USCG type approved ballast water treatment system before discharge. But until now only less systems had passed the stringent requirements of USCG. That means that only less systems are approved until now. OceanSaver is now able to offer BWTS in full compliance with both US Coast Guard and IMO standards.

OceanSaver‘s BWTS is available for small, medium and large vessels

According to the OceanSaver their system is for vessels with a system capacity of 1,500 to 7,000 m3/hour. That means that owners now have USCG certified systems available for small, medium and large vessels.

According to the Norwegians the USCG testing has been carried out with OceanSaver’s existing MKII system. Overall the MKII system has been through more than 60 tests over the past years as part of development of the system, class certification, IMO- and USCG approval processes. It’s performance is confirmed by operational experience and continuous customer feedback.

OceanSaver’s BWTS is based on electrochlorination. The company is partly owned by the energy shipping company BW Group.
