200-500 kWh

Corvus Energy was in 2018 selected by SEACOR Marine and Kongsberg Maritime as the supplier of lithium ion-based energy storage systems (ESS) for 4 platform supply vessels (PSVs) being retrofitted with a state-of-the-art hybrid power system. The Orca Energy ESS from Corvus will supply electrical power to the PSVs’ propulsion and dynamic positioning system’s electrical network to enable safe, environmentally friendly, and lower cost operations. Typical vessel operations will utilize the batteries to provide spinning reserve during critical vessel operations such as dynamic positioning, as well as to provide support for peak shaving, enabling the diesel engines to operate more efficiently. Utilizing battery power from the Orca ESS will not only reduce the environmental footprint of the offshore operations but will also significantly reduce operational costs, including fuel & maintenance on the engines.
