Corvus Energy reports that it has received an order from Wärtsilä for four energy storage systems (ESS) for installation in offshore support vessels operated by New Orleans headquartered Harvey Gulf International Marine.

The order follows the successful sea trial of Harvey Energy, the first PSV in the Americas to be retrofitted for LNG battery hybrid operation.

“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,” says Harvey Gulf CEO, Shane Guidry.

Wärtsilä will integrate the battery-based ESSs, each with a capacity of 745 kWh, into the vessels’ LNG-fueled hybrid-electric propulsion system. The ESS and Wärtsilä energy management system (EMS) will allow the vessels to operate in dynamic positioning 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.

Wärtsilä again selected Corvus Energy’s Orca Energy ESS as the battery type for this application.

“We are very proud and pleased to be selected again by Harvey Gulf and Wärtsilä,” says Sveinung Odegard, Vice President 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 serve the integrator and vessel owner in the years to come.”

The four LNG-battery hybrid vessels Harvey Liberty, Harvey Power, Harvey Freedom and Harvey America will be fitted with the 1,100 V DC – 745 kWh ESSs in 2021 and are expected to go into service with it in early 2022.
