Freight and Passenger Ferry Group Choose Neighbours to Power New Dual Fuel Ship

LNG Offers Operating and Environmental Benefits
Shipping News Feature
FINLAND – When freight and passenger group Viking line laid down plans to build a new luxury and environmentally friendly ferry at the Xiamen Shipbuilding Industry yard in China, it turned to neighbouring engine and vessel technology specialist Wärtsilä to provide both the dual-fuel engines, which will run primarily on liquefied natural gas (LNG), and much of the other equipment necessary to ensure the ship enjoys both low operating costs, and a minimal environmental footprint.

The six Wärtsilä 31DF which will power the vessel will be the first marine application for the dual-fuel version of an engine package which has achieved a Guinness World Record as the world's most efficient in its 4-stroke diesel configuration. The two Finnish companies agreed that the ship will also benefit from other Wärtsilä products including a LNGPac fuel storage and supply system, an advanced Compact Silencer System (CSS), high quality bow thrusters, the ballast water management system (BWMS), and the company’s Nacos Platinum integrated navigation system.

The Nacos Platinum system integrates various functions into a single system, allowing the vessel to be navigated, controlled, and monitored from several onboard positions, thus providing unequalled flexibility and convenience. The Wärtsilä BWMS is designed to render the ballast water discharge harmless of invasive species, as mandated by the IMO regulation which came into force in September.

The recently launched Wärtsilä SmartPredict system is also included in the overall fit out package. Described by the makers as ‘an innovation’ this is designed to provide ships with greater safety and more efficient operations by displaying a vessel's predicted future position and heading. It evaluates the wind and sea forces affecting the vessel to provide advanced motion prediction and has a configurable prediction time display. Roger Holm, President, Wärtsilä Marine Solutions, comments:

"A new era in ferry operations was established in 2013 when Viking Line's Viking Grace with Wärtsilä dual-fuel engines became the world's largest RoPax ferry to operate on LNG fuel. This latest Viking project represents another milestone as it will be the first vessel fitted with the highly efficient Wärtsilä 31DF engines. Both cases highlight the value our know-how and technology brings to our customers.”

Viking Line operates between Finland, the Åland Islands, Sweden and Estonia and the new ship, the first LNG fuelled ferry of this size and standard to be built in China and on which the shipping line has an option for a second vessel, will operate in the Baltic Sea between Turku, Finland and Stockholm, Sweden from early in 2021. Jan Hanses, President and CEO, Viking Line, observed:

"The value of operating with Wärtsilä engines fuelled by LNG has been well established through our experience with the Viking Grace. Furthermore, the LNGPac fuel system provides the necessary safety and non-stop operation required, so we had no hesitation in once again specifying Wärtsilä for this project.”
