Optimarin bags USCG's first US type-approval for ballast water management

In a significant development the US Coast Guard issued the first US type-approval certificate for a ballast water management system to Optimarin.

The Coast Guard Marine Safety Center issued the certificate Friday after Optimarin's application for US type-approval was reviewed and determined to meet USCG's requirements contained in 46 C.F.R. § 162.060.

'While this is a significant milestone, it is the first of multiple system approvals that are needed to mitigate the threat of harmful aquatic invasive species,' noted Rear Adm. Paul Thomas, assistant commandant for prevention policy. 'One size does not fit all, so we will continue to evaluate other systems submitted by multiple manufacturers with the intent to provide options that meet shipping’s varying needs.'

The Optimarin Ballast System is based on filtration as pre-treatment and high doses of UV irradiation for inactivation of marine organisms, viruses and bacteria. Ballast water is UV-treated during ballasting and de-ballasting to ensure the dual UV effect. The water is filtered only during ballasting. The system does not use or generate chemicals or biocides in its treatment or cleaning processes and is certified to operate in all salinities.

Optimarin is based in Sandnes, Norway, and has offices in six countries, including the US, in Stamford, Connecticut, plus sales representatives in further locations worldwide.
