Marine LNG Engines
Dual fuel engines are fuelled by either marine grade diesel, heavy fuel oil, or liquefied natural gas (LNG). Having multiple fuel options will allow vessels to transit without relying on one type of fuel. Studies show that LNG is the most efficient of fuels although limited access to LNG fueling stations limits the production of such engines. Vessels providing services in the LNG industry have been retrofitted with dual-fuel engines and have been proved to be extremely effective. Benefits of dual-fuel engines include Fuel and operational flexibility, high efficiency, low emissions, and operational cost advantages. Liquefied natural gas engines offer the marine transportation industry with an environmentally friendly alternative to provide power to vessels. In 2010 STX Finland and Viking Line signed an agreement to begin construction on what would be the largest environmentally friendly cruise ferry. Construction of NB 1376 will be completed in 2013. According to Viking Line, vessel NB 1376 will primarily be fuelled by liquefied natural gas. The cruise ferry will have an emission reduction comparison to diesel-fuelled engines of approximately 90%. Vessel NB 1376 nitrogen oxide emissions will be almost zero and sulphur oxide emissions will be at least 80% below the International Maritime Organization’s (IMO) standards. Rising greenhouse gases linked with global warming has become a major world problem. Environmentally friendly innovations in marine propulsion technology are necessary and the use of LNG fuel is a step toward achieving a healthier planet. Company profits from tax cuts and operational cost advantages has lead to the gradual growth of LNG fuel use in engines.
