Corvus Energy will supply a nearly 25 MWh lithium iron phosphate (LFP) battery system for the first-ever fully electric offshore vessel, set to enter service in 2027.
The electric Commissioning Service Operation Vessel (eCSOV) is being built by Spain’s Armon shipyard for UK-based shipowner Bibby Marine.
While the vessel will also be equipped with methanol engines, these will be used exclusively for charging, according to the manufacturer. Corvus Energy stated that this marks the largest LFP battery system ever deployed in a maritime project.
The battery-powered ship will rely on an optimized DC grid system to enhance efficiency and minimize energy losses. The engines will operate solely for charging at a constant load, extending battery lifespan and cutting emissions.
“A fully electric offshore vessel is something the industry has been working towards for a long time and marks a major milestone in offshore vessel operations,” said Pål Ove Husoy, VP Sales at Corvus Energy. “This eCSOV will be the first offshore vessel that can operate fully electric for a full day and will set a new standard for future offshore vessels.”
The battery system is scheduled for delivery to the shipyard in 2026, with the vessel expected to support offshore wind farm commissioning and operations from 2027.
