DESMI BWTS accepted by US Coast Guard

The AMS acceptance covers all salinities ranging from freshwater to marine water, something that only eight out of 52 issued AMS acceptances have achieved to date.

In addition, the RayClean BWTS AMS acceptance contains no limitation with regard to temperature of the water to be treated. The acceptance also covers the record setting wide UV-Transmission range, meaning the RayClean can treat dirty and unclear water that no other UV system on the market is currently approved for.

“The general awareness about limitations of type approved ballast water treatment systems is growing amongst shipowners. They have realised that the risk associated with having a BWTS on a vessel, which is not approved for treatment of water with low salinity or low temperature, is not acceptable,” said Rasmus Folsø, CEO of DESMI Ocean Guard.

“It can lead to fines, detainments in port and ultimately require installation of a new system,” he added.

RayClean was developed on the back of DESMI’s OxyClean BWTS, which was the first system in the world to receive the IMO and AMS approvals in all water salinities. The company says the development has been focused on creating a system that is simple, will work in all salinities and temperatures and in the most challenging unclear water conditions.

DESMI is now working on obtaining a full USCG type approval for the RayClean system.
