Rolls-Royce to supply diesel-battery hybrid power for NCA’s latest workboat
The vessel, due for delivery late in 2018 from Norwegian shipyard Fitjar Mekaniske Verft, will be the second to have a hybrid set-up, but its battery capacity of 2,000 kWh will be significantly higher than the 850 kWh of capacity installed on board sister ship Bøkfjord, named last September. This will enable the OV Ryvingen to operate on battery power for several hours, and batteries will also be used when the vessel is in port, where they can be recharged if power supplies are available.
The 46.6m-long OV Ryvingen will incorporate a range of other innovative features. For example, the vessel will store heat from the main engine and reuse it in port to heat the crew’s quarters. Rolls-Royce will also provide other key components including a Bergen main engine, permanent magnet azimuth propellers and thrusters, automation and electrical systems, dynamic positioning and a control system.
The two vessels are the third and fourth in the NCA’s fleet renewal programme comprising six to eight ships in total. NCA vessels carry out a range of functions including oil spill protection and the maintenance of shipping lanes.
