Ulstein orders Corvus batteries for Olympic offshore

Marine battery solutions provider Corvus Energy has won an order from Ulstein Power & Control to deliver energy storage systems for two Construction Services Operation Vessels (CSOVs) to be built for the Norwegian owner of Olympic offshore vessels.

The two offshore wind service vessels, based on the Ulstein SX222 design with Twin X-Stern from Ulstein Design & Solutions AS, will have hybrid battery propulsion.

During operation, ships remain positioned at the turbines most of the time, and with the main propellers forward and aft, these ships will reduce power requirements to a new level when in DP.

Ulstein Power & Control is the integrator and chose Corvus Orca Energy, which Corvus says is the marine ESS with the most installations in the world – for the two new buildings.

Pål Ove Husøy, Vice President of Sales, Corvus’ newly opened sales office in Fosnavåg, Norway, said the company sees increased interest in batteries from across the offshore wind segment as well as increasingly larger battery installations.

“Due to the operational profile of SOVs, the potential for reducing emissions and costs by installing batteries is very high. This contract will be the largest battery installation for SOVs to date,” he said.

Pål Ove adds: “This segment is also next on the list of total zero emissions operations. With demands for even larger battery systems, we see that our new Corvus Blue Whale ESS has great potential for this type of operation. Blue Whale is a ground-breaking energy storage system specifically designed to meet large energy requirements and can enable emissions-free operations for much longer periods of time.

Vessels are prepared for methanol fuel and have space available for additional battery capacity for fully electric charging when the infrastructure for this is available. The ships are expected to be delivered in the spring and summer of 2023.
