Norway-based ballast treatment system maker Optimarin has confirmed receipt of a revised IMO G8 certificate for its ballast water treatment technology.

The news ensures complete global compliance for a growing customer base, with the very latest orders received from  Arriva Shipping, for its fleet of advanced dry bulk vessels, and Østensjø Rederi, for four newbuilds currently under construction at Spain’s Gondan shipyard.

The latest development follows a successful testing programme at Norway’s NIVA facility, from September 2019 to June 2020, where a total of 32 IMO and USCG tests were run in parallel with two filters simultaneously across three salinity conditions (fresh, brackish and marine water), with zero interruptions or mechanical issues recorded.

“Our simple, easy to install and environmentally friendly UV-based technology has a history of reliable operation, both at sea, with our customers, and in the most stringent testing environments,” commented Leiv Kallestad, CEO, Optimarin. “Market leading compliance, reliability and performance have been central to building our reputation in the market. We’re pleased to move forwards with a certificate for a top-class system that ensures our customers can enjoy flexible, worldwide operations with complete peace of mind.”

The revised IMO G8 guidelines come into force on 28 October. All systems installed after that date must meet the new, stricter criteria to comply with IMO’s Ballast Water Management convention. The regulations do not affect systems installed prior to the deadline.

“Shipowners and operators looking to select systems need to ensure that technology is future proof in terms of regulations,” Kallestad noted. “Suppliers, like Optimarin, that can offer full USCG and revised G8 certification, alongside a long history of operational success, will provide that reassurance. It’s important to identify suppliers that actually have the paperwork now, rather than promising they will get it, to make sure installations and operations proceed with the minimal of disruption… or disappointment. In other words, choose a partner you know you can trust.”
