Worlds most powerful LNG-ferry for Gotland

The launching of Rederi AB Gotland's new LNG ferry in China on Monday the 24th of July. This is the 2nd LNG ferry that the Chinese yard, GSI, builds for Rederi AB Gotland. The vessel is to be delivered in 2018.

MV THJELVAR, the last of two newbuilt vessels for Rederiaktiebolaget Gotland, was launched July 24th 2017 from slip no. 2 at Guangzhou Shipyard Intl. Co. Ltd in China.

Together with newbuilding VISBORG, which launched in November 2016, THJELVAR will be among the world's most powerful and fastest LNG-fuelled RoPax-ferries and will service the route between Nynäshamn and Visby, Gotland (Sweden). OSK-ShipTech A/S has been consulting naval architects for both owner, during concept and contract designs, as well as yard for basic naval architectural design.

OSK-ShipTech has also been interior designers on the project.

OSK-ShipTech A/S to China
Danish naval architect consultancy, OSK-ShipTech A/S and GSI (Guangzhou Shipyard International), China have signed a contract for continuation of design works in relation to the new RoPax ferry recently contracted between GSI and one of Sweden’s leading passenger shipping companies, Gotlandsbolaget. The ferry will service the route between Nynäshamn and Visby, Gotland, and will be one of the world’s most powerful and fastest ferries to be powered by LNG (Liquefied Natural Gas).

Higher capacity, lower fuel consumption

The 200 meter long vessel will have a deadweight capacity of approximately 4,800 tonnes, room for about 1650 passengers and 1750 trailer lane meters. Despite the vessel having a 1200 ton larger displacement than Gotlandsbolaget’s existing two RoPax vessels MS Visby and MS Gotland - also build by GSI and delivered in 2003, the design team involved in the project has ensured significant reduction on fuel consumption. “We have experienced excellent cooperation between OSK-ShipTech, the owners, GSI and the test tank Marin with lots of in-house CFD optimization, tank testing and retesting. Bearing the given constraints of the project in mind, I think we have pinched every possible saving out of the hull lines” says Kristian Carøe Lind, OSKShipTech’s Head of Department in the Aarhus headquarter.

Prior to the contract between GSI and Gotlandsbolaget, OSK-ShipTech A/S was assigned by Gotlandsbolaget to prepare contract designs and specifications. Now working for GSI, OSK-ShipTech A/S will head the basic and detailed design process, primarily on exterior/interior designs, safety and environmental arrangements as well as general project coordination.

Powered by LNG and with an array of energy saving applications, the new ferry will provide an environmental and friendly addition to the existing fleet of Gotlandsbolaget including large savings on emission of CO2, NOx and SOx.
