Wärtsilä, Shell To Promote LNG As Marine Fuel

Posted on September 8, 2011

Wärtsilä and Shell Oil Co. have signed a joint cooperation agreement aimed at promoting and accelerating the use of liquefied natural gas (LNG) as a marine fuel. The agreement was signed in August and will run for several years.

Supplies of low cost, low emissions LNG fuel will be made available to Wärtsilä natural gas powered vessel operators, and other customers by Shell. The agreement will focus first on supplies from the U.S. Gulf Coast, and then expand their efforts to cover a broader geographical range, according to the companies.

Gas-fuelled marine engines are seen as a logical means for ship owners and operators to comply with environmental legislation. This agreement looks to increase and ease the availability of natural gas for marine engine use, as well as develop the supply chain and infrastructure to facilitate the bunkering of LNG fuel. The two companies will jointly move these developments to marine markets.

Wärtsilä already has developed dual-fuel engine technology, allowing the same engine to be operated on gas and diesel fuel. This dual-fuel capability means that when running in gas mode, the environmental impact is minimized since nitrogen oxides (NOx) are reduced by about 85% compared to diesel operation; sulfur oxide (SOx) emissions are eliminated as gas doesn’t contain sulfur; and emissions of CO2 are lowered. Natural gas has no residuals, meaning the production of particulates is non-existent.
