A new passenger ferry being built for Swedish operator Rederi AB Gotland will be fuelled by liquefied natural gas and will feature a Wärtsilä integrated solution.
The Wärtsilä integrated solution includes a complete LNG-powered propulsion- and fuel storage and supply system, as well as comprehensive project services.This will be the first Swedish flagged LNG-powered passenger vessel and the first LNG fuelled high speed RoPax ferry in the world. The vessel is being built at the Guangzhou Shipyard International (GSI) yard in China and when delivered, will sail between the Swedish mainland and the island of Gotland. GSI placed the contract with Wärtsilä in November.
By operating on LNG, the new 200 metre long ferry will comply with the International Maritime Organization’s (IMO) Tier III regulations regarding emissions of nitrogen oxides (NOx). Furthermore, it will meet the sulphur (SOx) emissions limitations required for operating in the Northern European sulphur emissions controlled areas (SECA), while emissions of particulates will also be reduced to virtually zero. In addition to its compliance with emissions legislation, the ferry will also meet the requirements of the IMO’s recently agreed IGF Code regarding the safety of LNG fuelled ships.
In addition to the complete LNG-powered propulsion and fuel & storage system, the Wärtsilä integrated solution will include services relating to project management, integration engineering, on-site support and overall commissioning responsibility.
Wärtsilä’s scope of responsibility includes four Wärtsilä 50DF dual-fuel engines, two gearboxes, two controllable pitch propellers (CPPs) with remote control system, two Energopac rudders, two tunnel thrusters, four Wärtsilä 20DF dual-fuel auxiliary generating sets, two Wärtsilä LNGPac fuel gas handling systems, gas valve units, a compact silencer system (CSS), an IMO approved Wärtsilä Aquarius UV ballast water management system, an Oily Water Separator together with a Bilge Water Guard to monitor and prevent oily water being discharged to the sea, project management services, integration engineering services, commissioning services and on-site supervision during installation. Delivery of the Wärtsilä equipment will begin at the end of 2015 and the ship is scheduled to be in operation in 2017.
The ship will carry approximately 1650 passengers, will have 1750 trailer lane metres and can accommodate a corresponding number of passenger cars, campers and busses. It has been designed to meet the DNV-GL classification society’s high comfort ratings for climate, noise and vibrations.
