World’s 1st Fully Electric Offshore Vessel To Enter Operation In 2027

Corvus Energy, a leading supplier of zero-emission solutions for the maritime and offshore industry, has announced that it will provide a massive battery system for the world’s first fully electric offshore vessel.

The vessel, an electric Commissioning Service Operation Vessel (eCSOV), will be built by Spain’s Armon shipyard for UK-based shipowner Bibby Marine Ltd. It is expected to enter operation in 2027 to support the commissioning and maintenance of offshore wind farms.

Corvus Energy will supply its Blue Whale Battery Energy Storage System (BESS), which will provide close to 25MWh of power, making it the largest Lithium Iron Phosphate (LFP) battery system ever used in a maritime project.

A Corvus Energy spokesperson stated that the offshore industry has been working towards a fully electric vessel for a long time. The eCSOV will be the first offshore vessel capable of operating fully on battery power for an entire day, setting a new standard for future offshore vessels.

The ship will also include dual-fuel methanol engines, which will work alongside the battery system to reduce carbon emissions and improve energy efficiency while maintaining high reliability and performance.

Corvus Energy has collaborated with the shipowner, designer, and integrator to optimise the vessel’s power system. Unlike traditional hybrid vessels, this eCSOV will use its large battery pack as the main power source, while the engines will be used only for charging at a constant optimised load.

This approach maximises efficiency, extends battery life, and significantly reduces emissions. The vessel will also feature an innovative DC grid architecture, which will minimise energy losses and ensure seamless power distribution.

Additionally, the ship will introduce offshore charging capabilities, allowing the battery to be recharged while maintaining Dynamic Positioning (DP) for station-keeping. This will be the first time such a system is implemented in a Service Operation Vessel (SOV).

A representative from Bibby Marine stated that the company is excited to work with Corvus Energy on this groundbreaking eCSOV project.

The company selected Corvus Energy for its expertise in handling complex vessel projects. The LFP battery technology was specifically chosen due to its safety, long lifespan, and reliability, making it a perfect fit for the eCSOV’s operational needs.

The battery system is scheduled for delivery to the shipyard in 2026, and the vessel is expected to begin operation in 2027.

Corvus Energy is a leading global supplier of energy storage systems (ESS) for maritime, offshore, and port applications. The company offers modular lithium-ion battery systems and Hydrogen PEM fuel cell systems, supporting various vessel types.

With experience in over 1,200 projects, Corvus Energy powers more than 50% of the world’s zero-emission vessels.
