The Gas Valve Train is a high-pressure double block and bleed system designed for directing flow of methane or ethane gas to 2-stroke dual fuel engines. In case of normal or emergency shutdown, the GVT MkIII will stop the gas supply to the engine and bleed through the vent header.
LNG significantly reduces or eliminates emissions of SOx and particulate matter. The reduction of NOx emissions depends on engine technology, but is typically well within the strictest International Maritime Organization NOx Tier III requirements in Emission Control Areas. When considering the complete lifecycle for LNG, the greenhouse gas savings amount to is up to 18% compared with traditional marine fuels.
