Rolls-Royce to equip hybrid system on new Norwegian Coastal Administration vessel

Rolls-Royce has won a deal from Norwegian shipyard Fitjar Mekaniske Verft to supply its hybrid battery system for a new multipurpose vessel known as OV Ryvingen, which is set to be owned by the Norwegian Coastal Administration.

Rolls-Royce has won a deal from Norwegian shipyard Fitjar Mekaniske Verft to supply its hybrid battery system for a new multipurpose vessel known as OV Ryvingen, which is set to be owned by the Norwegian Coastal Administration.

Ryvingen's hybrid system contains two generators and a battery pack and will have a capacity of 2,000kWh.

Rolls-Royce will also supply various other equipment under the new agreement, including a Bergen main engine, permanent-magnet azimuth propulsion propellers and thrusters. 

Additionally, the company is set to provide an automation device, a SAVe CUBE electrical system, a dynamic positioning (DP) unit and various control systems for Ryvingen as part of the deal.

The Rolls-Royce equipment will reduce the vessel's noise and vibration levels upon installation.

Rolls-Royce sales general manager John Roger Nesje said: “A complete systems delivery like this enables us to think efficiency and low emissions throughout the ship’s equipment.

“For example, the Ryvingen’s main engine will be connected to our electrical system, which means its rotational speed can constantly be varied depending on the load, so we save energy here as well.”

Ryvingen will feature a length of 46.6m and a width of 12m, and is expected to be delivered by the end of next year. The vessel will be capable of operating on a combination of diesel and battery-driven power.

It is set to join its sister ship, the hybrid vessel Bøkfjord, for carrying out various services such as oil spill protection and maintenance of shipping lanes.

Ryvingen’s operating profile will also allow it to run only on battery power for several hours if required.

The battery system has been specially designed to provide power when the vessel is docked, which means the diesel engines will not have to be kept running.
