Corvus Energy Orca ESS to power one of the world’s cleanest offshore platform supply vessels

Corvus Energy’s next generation Orca Energy ESS has been selected by Wärtsilä to provide battery power to the Eidesvik Viking Princess

Richmond, B.C. – May 30, 2017 – Corvus Energy is pleased to announce that it has been selected by Wärtsilä as the supplier of lithium ion based energy storage systems (ESS) for the retrofit of an offshore platform supply vessel, the Viking Princess. Corvus will be supplying the industry leading Orca Energy ESS solution for the project. The Viking Princess is the second Eidesvik platform supply vessel to adopt a Corvus energy storage system, following the Viking Lady.

The Viking Princess is a state-of-the-art offshore supply vessel designed to safely service offshore installations in the extremely harsh waters of the North Sea. The 533kWh Orca Energy ESS will be installed on the vessel in a hybrid arrangement, replacing one LNG genset, approved by DNVGL & NMA as spinning reserve resulting in 1 tonne of fuel savings per day.

“Corvus Energy is honoured to be working with Wärtsilä and Eidesvik once again, on the retrofit of the Viking Princess”, says 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 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.”

As the leading manufacturer of energy storage systems for maritime applications, Corvus designed and built the Orca ESS solutions portfolio based on the experience from 70+ installations utilizing a Corvus ESS, totaling over 35MWh and 1 million operating hours. Rather than a single product, the Orca ESS product line delivers a range of products which are designed to meet the needs of various marine customers.
