Corvus Supplies ESS for Edda Freya

Corvus Energy, Siemens AS and Ostensjo Rederi strengthen their partnerships with a second offshore vessel project.

The new 150m MPSV to be named the Edda Freya will incorporate a 1050VDC, 546kWh Corvus ESS consisting of 84 Corvus Energy AT6500 advanced lithium polymer battery modules.

This new project follows from the Edda Ferd hybrid platform supply vessel (PSV) project completed by the same partners in 2014. The Corvus ESS will again be integrated with the Siemens BlueDrive PlusC™ electric propulsion solution that will provide efficient hybrid propulsion to the new MPSV and also provide backup power in the case of blackout, the company explained.

Edda Ferd and Edda Freya are part of Ostensjo Rederi’s environmental concept “Mindset”. The vessels optimize the use of diesel generators and the ESS to significantly reduce fuel consumption and emissions, allowing a 20 to 25% energy savings over comparable vessels, Corvus added.

“We are very pleased to partner again with Siemens and Ostensjo, this time on the Edda Freya MPSV,” said Andrew Morden, President and CEO, Corvus Energy. “Balancing environmental protection and profit is not an easy task in the North Sea.  We are proud to supply an ESS to the vessel that can meet the operational rigors of offshore service.”

Corvus’ lithium polymer energy storage technology is an effective solution for hybridization of commercial vessels with dynamic duty cycles. It provides the consistent power and reliability to support greatly improved efficiencies of marine propulsion systems.
