Wartsila selects Corvus Energy to supply energy storage systems

Corvus-Energy-ITS-2010-18

Corvus Energy has been selected by Wartsila to supply energy storage systems (ESS) for three new battery hybrid ferries for Finnlines. The Finnish ferry operator with a fleet of 20 ships is part of Italy’s Grimaldi Group.

All three ships will have the RINA’s Green Plus class notation and will be the most modern and environmentally friendly Roll-on/Roll-off (Ro-Ro) vessels ever built. The ships are designed for flexible Ro-Ro cargo.

The vessels will be built with the latest technology to ensure the lowest CO2 emissions. In addition to Wartsila’s  Hybrid Power Conversion system which includes Corvus ESS that enables zero-emission operations in port, they will be equipped with Wartsila’s energy efficient engines, exhaust gas scrubbers and an innovative air lubrication system to reduce hull resistance.

The vessels’ hulls are similar to those of the “Grimaldi Green 5th Generation” vessels but are customized for Finnlines to meet their requirements of heavy cargo and operation in cold climates with the highest Finnish/Swedish ice class.

“There is significant potential for fuel and emissions reduction in Ro-Ro ships as they are normally on fixed routes,” said Roger Rosvold, senior vice president of Sales at Corvus Energy.

The vessels will be built at Nanjing shipyard and are expected for delivery in 2021 and onwards for operation in the Baltic Sea.
