Wärtsilä to power LNG-fuelled RoPax ferry

LNG Industry,


A new passenger ferry being built for Swedish operator Rederi AB Gotland will be fuelled by LNG and will feature a Wärtsilä integrated solution.

The Wärtsilä 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.

Emission reduction

By fuelling with LNG, the new 200 m ferry will comply with the International Maritime Organization's (IMO) Tier III regulations regarding emissions of nitrogen oxides (NOx). It will also meet the sulfur (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. Additionally, the ferry will meet the requirements of the IMO's recently agreed IGF Code regarding the safety of LNG fuelled ships.

"This vessel will have a minimal environmental footprint and we are proud to be working with Wärtsilä to make this possible. Wärtsilä's know-how and experience with gas fuelled vessels is unmatched in the industry," commented Håkan Johansson, Managing Director of Rederi AB Gotland.

Dual-fuel engines

Wärtsilä's scope of responsibility includes four 50DF dual-fuel engines, two gearboxes, two controllable pitch propellers (CPPs) with remote control system, two Energopac rudders, two tunnel thrusters, four 20DF dual-fuel auxiliary generating sets, two LNGPac fuel gas handling systems, gas valve units, a compact silencer system (CSS), an IMO approved 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.

RoPax ferry

"Rederi AB Gotland will introduce a ground-breaking vessel design for its crown route, and Wärtsilä is proud to take a large share of the responsibility for its accomplishment. Together with Guangzhou Shipyard International in China and Danish designers OSK-Shiptech, we will realise the first of an entirely new generation of fast, yet environmentally sound RoPax ferries. Not only will Wärtsilä deliver the entire LNG fuel handling and power and propulsion system, we will also provide comprehensive project management services, such as integration engineering, on-site support and extended commissioning. We believe that this combination is a key success factor for this and other challenging ship building projects. It highlights Wärtsilä's position as the marine industry's leading provider of integrated solutions," added Wilco van der Linden, Director Business Development, Merchant Cruise and Ferry at Wärtsilä Solutions.

The ship will carry approximately 1650 passengers, will have 1750 trailer lane metres and can accommodate a corresponding number of passenger cars, campers and buses.
