Corvus Energy announced that it has been selected by Rolls-Royce as the supplier of a lithium ion based energy storage system (ESS) for the Norwegian Coastal Administration’s new multipurpose vessel OV Ryvingen.
Under the agreement, the Orca Energy ESS from Corvus will supply electrical power for all-electric propulsion and for electrical needs while docked.
The OV Ryvingen is the Norwegian Coastal Administration’s second vessel to combine traditional diesel power with battery-driven operation and the fourth vessel in the Norwegian Coastal Administration’s fleet renewal programme, consisting of six to eight ships in total. The Ryvingen is a multipurpose vessel, which performs operations relating to oil spill protection and the maintenance of shipping lanes.
The Orca ESS will have a capacity of 2938 kilowatt hours (kWh), that will allow the Ryvingen to run on battery power alone for several hours, without using the diesel engine. In addition, the batteries will provide power when the vessel is docked, so the diesel engines will not have to be kept running. The batteries will be recharged from an onshore power supply in ports where this is available. The complete equipment package will also cut noise and vibration levels on board.
The 46.6m long and 12m wide OV Ryvingen is scheduled for delivery towards the end of 2018.
“The electrification of vessels will see an increasing utilization of higher battery capacities”, says Halvard Hauso, Senior Vice President of Business Development of Corvus Energy. “As with the Ryvingen, an increasing number of vessels will use the Orca energy storage system to deliver a greater proportion of the vessel’s power.”
