Nevertheless increasingly strict emission regulation as well as high fuel prices create a demand for innovative solutions in ship propulsion. One way to deal with these challenges is the use of LNG as ship's fuel, thus significantly decreasing emissions of sulphur oxides, particles, NOx, and carbon dioxide. All major engine makers have their designs for gasfuelled or dual-fuel engines available, but on top of the engines such ships require additional systems for the storage of LNG under cryogenic conditions and for the processing of gas to a pressure and temperature as required by engines. Depending on the engine type these requirements may strongly differ,e.g. for two stroke engines following the Diesel principle the injection pressure is up to 300 bar g. As a world leading EPCS contractor for cargo systems for cryogenic gases like LNG, Ethylene and LPG, TGE Marine Gas Engineering is very familiar with cryogenic storage and processing on board of seagoing vessels and offshore platforms. TGE has transferred this vast experience into the design of LNG fuel gas systems for all types of engines. These fuel supply systems are ready for the market and proven to meet the requirements regarding safe and reliable onboard operation. A special focus has been taken on high-pressure gas supply systems to feed two-stroke engines like MAN ME-Gl These very sophisticated systems have been evaluated in detail and in close cooperation with the engine maker in order to make sure that they are ready for reliable operation. On top of the storage and processing system a LNG fuelled vessel will have a number of safety and auxiliary systems like fire & gas detection, ventilation, heating system as well as automation system. TGE's paper will also cover the main aspects of such systems that are mandatory for safe operation. Further to the onboard systems the bunkering of LNG is in a very early stage of development, only very few places in the world are prepared to fuel smaller ships. Bunker vessels to cover the requirements for larger vessels are not yet in operation. Using TGE's experience from the gas carrier market, we have developed solutions to close this gap in infrastructure in order to enable the LNG as fuel development to take off.
