Corvus Energy (Corvus) today announced that it has been selected by Wärtsilä to supply its lithium ion based energy storage systems (ESS) for the retrofit of an offshore platform supply vessel, the Viking Princess.

As Ship & Bunker reported last week, Wärtsilä has signed an agreement with Eidesvik Offshore ASA (Eidesvik) to install a bunker-saving hybrid system with batteries onboard its liquefied natural gas (LNG)-powered Viking Princess.

"Corvus Energy is honoured to be working with Wärtsilä and Eidesvik once again, on the retrofit of the Viking Princess," said Halvard Hauso, SVP Business Development of Corvus Energy.

"The first Eidesvik ship powered by a Corvus ESS, the Viking Lady, has become a well-known industry case study of a hybrid-electric vessel. We are excited to demonstrate on the Viking Princess that the well-documented benefits of an ESS on offshore vessels can be achieved at a lower cost to ship owners, thereby improving the economic rationale for such deployments."

Corvus' 533kWh Orca Energy ESS is set be installed on the OSV in a hybrid arrangement, replacing one LNG genset, having been approved by DNV GL and NMA as spinning reserve that Corvus says will result in 1 tonne of fuel savings per day.

"Corvus Energy, and more specifically the Orca Energy ESS, was selected for its compelling safety, performance and return on investment," said Dag Håvard Håvardsholm of Wärtsilä.

"Based on the innovative approach of Orca and Corvus' industry leading experience, ship owner Eidesvik has complete trust in this solution."
