Viking Grace

Wärtsilä supplied the propulsion machinery for the Viking Grace, the world’s first LNG powered passenger vessel.

According to the agreement, Wärtsilä's scope of supply includes four Wärtsilä 8L50DF main engines, the transverse bow and stern tunnel thrusters, as well as two stainless steel fixed pitch propellers with propeller shaft lines including environmentally sound shaft line seal systems, the LNG tanks and fuel supply and handling equipment with safety and automation systems. Due to the lowest possible pressure impulses generated by the propellers, the vibration level in the stern hull is very low. Wärtsilä will supply a sound-absorbing system to minimise noise generated by the engine, thus increasing passenger comfort. A low noise level is also important as the vessel's route passes through the Turku and Stockholm archipelagos.

Thanks to Wärtsilä’s dual fuel technology, the vessel can operate without restrictions in SECA and NECA sulphur and nitrogen monitoring areas.

Viking Line and Wärtsilä have for a long time successfully cooperated on ship propulsion systems. Over the years Wärtsilä has been the main supplier of diesel engines for Viking Line’s new vessels.

“It is in our best interests to co-operate with Wärtsilä since they are experts in the development of new types of engines and the use of alternative fuels, thereby lowering specific fuel consumption and enhancing environmentally safe operations. Wärtsilä is a close, domestic supplier who offers us the opportunity to collaborate in improving our operations and engine maintenance capabilities, through technical training and field testing. All this is very important, especially now that Viking Line is entering a new era of gas-electric driven operation.”
Tony Öhman, Technical Director in charge of Marine Operations and Newbuilding at Viking Line.
