Norwegian ballast water treatment (BWT) specialist Optimarin has become the first system supplier to gain full USCG type approval.

The Optimarin Ballast System (OBS) utilises a combination of filtration and powerful 35kW UV lamps to treat ballast water without the need for chemicals. So far, over 300 units have been installed worldwide with another 500 on order. Its modular nature ensures it is also easy to install on any vessel, newbuild or retrofit

Optimarin’s technology is certified by a comprehensive range of classification organisations, including DNV GL, Lloyd’s Register, Bureau Veritas, MLIT Japan, and American Bureau of Shipping. Apart from the USCG approval, the system has also been approved by the IMO.
