Rolls-Royce to Power Havila Kystruten’s New Ferries

Norwegian shipowner Havila Kystruten has hired engineering company Rolls-Royce to provide power and propulsion for its new Ro-Pax vessels.

Rolls-Royce will provide a fully integrated LNG power and propulsion solution to all four Havyard 923 design ships. This includes two LNG fuel tanks with process system, and control and safety systems, four Bergen gas engines, main propulsion thrusters of type Azipull with Permanent Magnet (PM) drive motor, PM tunnel thrusters, and stabilisers of type Neptune 200.

The LNG fuel system from Rolls-Royce will supply Bergen gas generator sets. Each vessel will have two engines with nine in-line cylinders, and two with six cylinders. The engines can operate on variable speed to reduce both fuel consumption and emissions.

The Bergen engines series reduces total greenhouse gas (GHG) emissions by about 20 per cent compared to a similar diesel engine, and is IMO Tier 3 compliant, according to Rolls-Royce.

“Havila Kystruten has chosen a LNG fuel system that builds on our long experience with these type of systems, designed to be robust and reliable in rough weather conditions. No less important is the fact that the system and its engines will provide a significant reduction in emissions compared to conventional diesel engines,” Steinar Oppedal, Technical Product Manager for LNG Fuel Systems, Rolls-Royce – Commercial Marine said.

The four vessels are scheduled to start operating on the coastal route between the cities of Bergen in south western, and Kirkenes in northern, Norway from January 2021.

Havila Kystruten contracted Spain’s Astillero Hijos de J. Barreras shipyard to build two of the cruise ferries and Turkey’s Tersan yard to construct the remaining two.
