Corvus Energy, one of the leaders in zero-emission solutions for the offshore and marine industry, will deliver a mega-size battery system for the first fully electric offshore vessel ever built.
The electric Commissioning Service Operation Vessel (eCSOV) will be constructed by Armon shipyard in Spain for UK-based Bibby Marine Ltd. Corvus Energy will supply its Blue Whale Battery Energy Storage System (BESS), delivering nearly 25MWh of power—the largest LFP (Lithium Iron Phosphate) battery system ever used in a maritime project.
“A fully electric offshore vessel has long been a goal for the industry, and this marks a major milestone,” said Pål Ove Husoy, VP Sales at Corvus Energy. The vessel will operate fully electric for a full day, setting a new standard for offshore operations with a hybrid system combining battery power and dual-fuel methanol engines to cut carbon emissions and enhance efficiency.
The innovative DC grid architecture ensures seamless power distribution, while offshore charging capabilities allow simultaneous battery charging while maintaining DP for station-keeping—an industry first.
Bibby Marine’s New Build Director, Gavin Forward, emphasized the importance of this collaboration, stating that Corvus Energy’s expertise and the safety, longevity, and reliability of LFP battery chemistry made them the ideal partner.
Corvus Energy will deliver the equipment in 2026, with the vessel entering operation in 2027, supporting offshore wind farm commissioning and operations. This landmark project brings the maritime industry closer to net-zero emissions.
