Norwegian company OceanSaver has secured a final type approval certificate from the US Armed Forces’ division, US Coast Guard (USCG), for being first ballast water treatment system supplier that uses electrochlorination.

With the certification, OceanSaver offers the only USCG-type approved system for both medium and large vessels, like LR1s, VLCCs, and large gas carriers.

According to US regulations, all ships trading in US waters need to treat their ballast water with USCG-type approved ballast water treatment system before discharge.

"We are very proud that OceanSaver has obtained the USCG type approval with no restrictions."

To date only OceanSaver has been able to offer the system, which comply with both US Coast Guard and International Maritime Organisation (IMO) standards, to the ship owners.

OceanSaver Sales and Marketing vice-president Alan Linderoth said: “The OceanSaver system is a perfect match for medium to large vessels with a system capacity of 1,500m³/h to 7,200m³/h, 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 USCG testing has been conducted using the company’s existing MKII system without significant modifications, thereby proving the efficiency as well as reliability of the system.

The USCG approval certificate does not impose any restrictions on daily vessel operations.

OceanSaver chief operating officer Helle Hundseid said: “We are very proud that OceanSaver has obtained the USCG type approval with no restrictions.

“This means that the operation of the system will not affect the vessel’s trade or cargo operation.”

According to Hundseid, OceanSaver is prepared for larger volumes and can provide financing packages as well as support ship owners in meeting future compliance dates.
