Corvus to supply ESS for US offshore support vessel fleet

LinkedIn +

Corvus Energy has received an order from Wärtsilä to supply four energy storage systems (ESS) to equip the offshore support vessel fleet operated by Louisiana-based Harvey Gulf.

The orders follow the successful sea trial of Harvey Energy, the first-ever LNG-battery hybrid retrofit of a platform supply vessel (PSV) in the Americas, and operated by Harvey Gulf. The company’s CEO, Shane Guidry, reported that clients and investors are increasingly demanding energy efficiency and emissions reduction: “This fleet of vessels will be crucial in assisting our clients’ efforts to achieve net carbon zero, and we will continue to listen to them and invest in technology that will assist with their goals.”

Wärtsilä will integrate the battery-based ESSs, each with a capacity of 745kWh, into its LNG-fueled hybrid-electric propulsion system. The ESS, combined with the Wärtsilä EMS, will allow the vessels to operate in dynamic position mode on a single engine augmented by battery power, while also allowing them to function more efficiently in transit and other operational modes. In addition, they will be capable of running on battery-power only when stationary.

Wärtsilä selected Corvus Energy’s Orca Energy ESS for this specific application, with the company claiming that its robust design, high C-rate and proven performance makes it the ideal fit to meet the demanding load profiles on the offshore platform supply vessels.

“We are very proud and pleased to be selected again by Harvey Gulf and Wärtsilä,” noted Sveinung Odegard, VP sales, North America, and president of Corvus Energy, USA. “Our technology, understanding of customer needs and commitments towards lifecycle support is again being acknowledged by receiving this order. We look forward to continuing to serve the integrator and vessel owner in the years to come.”
