Largest Battery System Delivered for First Fully Electric Offshore Vessel

Corvus Energy, a leading provider of zero-emission solutions for the offshore and marine industry, has announced the delivery of a mega-size battery system for the first fully electric offshore vessel ever to be constructed. The vessel, an electric Commissioning Service Operation Vessel (eCSOV), will be built by Armon shipyard in Spain for UK-based shipowner Bibby Marine Ltd. This groundbreaking project marks a significant milestone in offshore vessel operations and emphasizes the industry’s commitment to sustainability.

The Blue Whale Battery Energy Storage System (BESS) from Corvus Energy will supply close to 25MWh of power for the vessel, making it the largest LFP (Lithium Iron Phosphate) battery system ever delivered to a maritime project. This innovative system design, incorporating both battery power and dual-fuel methanol engines, will greatly reduce carbon emissions and increase energy efficiency for demanding offshore wind and renewable operations. The vessel will operate fully electric for a full day, setting a new standard for future offshore vessels.

Corvus Energy has collaborated closely with the shipowner, designer, and integrator to optimize the system design, utilizing the large battery pack as the primary power source. The vessel’s engines will run solely for charging at an optimized load, maximizing efficiency, extending battery lifespan, and reducing emissions. The unique DC grid architecture further enhances system performance by minimizing energy losses and ensuring seamless power distribution. The vessel is scheduled for operation in 2027, supporting the commissioning and operation of wind farms.

Gavin Forward, New Build Director at Bibby Marine, expressed excitement about the project, noting that it sets a new benchmark for sustainable offshore operations and drives the future of zero-emission vessel technology. Corvus Energy was selected for its expertise in delivering complex vessel projects, while the LFP battery chemistry was chosen for its alignment with the eCSOV’s operational profile. This project promises to accelerate the maritime sector’s path to net-zero emissions, offering enhanced safety, longevity, and reliability in the pursuit of sustainable operations.
