Optimarin has demonstrated how easy it is for existing Optimarin Ballast Systems (OBS) to be upgraded to full USCG compliance with a visit onboard Subsea7’s Seven Pacific.

The ballast water treatment (BWT) specialist, the first manufacturer to achieve USCG approval in December 2016, originally installed its UV-based technology onboard the advanced offshore construction and pipe-laying vessel in 2015. Since that point the 667-m3 market proven system has, according to Seven Pacific Chief Engineer Oddgeir Refvik, been running smoothly, with minimal maintenance and easy operation.

Easy does it

Refvik described the upgrade as “very straightforward”.

“It only took a couple of hours to perform,” he explains, “basically being a software modification. The service engineer brought an updated manual and information plate onboard, upgraded the software and then took us through the changes. That was it. We can now easily change the operation mode of our Optimarin BWT system between IMO or USCG mode.”
