Rolls-Royce has announced a contract to deliver a battery pack for Norwegian Coastal Administration’s new multipurpose vessel »Ryvingen«. It is the second one that combines traditional diesel power with battery-driven operation.
The battery pack will have an available capacity of[ds_preview] 2,000 kWh. A substantial increase from the 850 kWh capacity that is installed aboard its hybrid sister ship »Bøkfjord«. It also has twice the capacity of Norway’s first fully electric car and passenger ferry, »Ampere«.
According to Rolls-Royce the »Ryvingen« has an operating profile that allows it 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 can be recharged from an onshore power supply in ports where this is available.
»Ryvingen« is part of a fleet renewal program
Both the »Bøkfjord« and the »Ryvingen« are multipurpose vessels, which perform operations relating to oil spill protection and the maintenance of shipping lanes. They are the third and fourth vessels in the Norwegian Coastal Administration’s fleet renewal program, comprising of six to eight ships.
Rolls-Royce has signed the contract to deliver the hybrid system with the shipyard, Fitjar Mekaniske Verft, in Norway. This partnership has resulted in state-of-the-art technological advances. For example the »Ryvingen«’s ability to reuse heat from the vessel’s engine in an environmentally friendly manner sets it apart from its sister vessel. The vessel stores and reuses the surplus heat from its main engine to heat the crew’s quarters when the ship is in port, Rolls-Royce stated.
In addition to the hybrid system with two generators and the battery pack, Rolls-Royce will also deliver an extensive equipment package, including: a Bergen main engine, permanent-magnet azimuth propulsion propellers and thrusters, the automation system, SAVe CUBE electrical system, Dynamic Positioning (DP), and control systems.
The 46.60 m long and 12 m wide »Ryvingen« is scheduled for delivery towards the end of 2018.
