BERGEN, Norway and VANCOUVER – Wärtsilä has ordered energy storage systems (ESS) from Corvus Energy for four Harvey Gulf offshore support vessels.
Wärtsilä will integrate the battery-based Orca Energy ESSs, each with a capacity of 745 kWh, into its LNG-fueled hybrid-electric propulsion system. The ESS and Wärtsilä energy management system are expected to allow the vessels to operate in dynamic position mode on a single engine augmented by battery power, to operate more efficiently in transit and other operational modes, and to operate on battery-power only when stationary.
The four LNG-battery hybrid vessels Harvey Liberty, Harvey Power, Harvey Freedom, and Harvey America will be fitted with the 1100VDC – 745 kWh ESSs in 2021 and are expected to go into service in early 2022.
The orders follow the successful sea trial of Harvey Energy, the first-ever LNG-battery hybrid retrofit of a platform supply vessel in the Americas.
