近年来,燃料气体已成为IMO的主要讨论议题,且其商议结果已取得成效。从某一层面上说,考虑到液化气运输技术取得众多进步,气体航运业已修改了其管理气体运输船设计、建造和设备的标准。同时,海事部门已着手制定了一套新的国际标准,来管理以气体为燃料的船舶。由于预计以液化天然气(LNG)为动力的船舶在今后数年里数量将激增,作为让船舶所有人遵守日益严格限制船舶大气排放的一种途径,其主要焦点已集中于LNG。同时,该新标准也为船用推进系统中使用替代性低闪点气态或液态燃料留有余地。
In recent years, fuel gas has become the main topic of discussion of IMO, and the result of its deliberation has achieved results. At one level, considering the many advances in liquefied gas transportation technology, the gas shipping industry has revised its standards for the design, construction and equipment of gas carriers. At the same time, the maritime sector has embarked on a new set of international standards to manage gas-fueled vessels. As LNG-powered vessels are expected to soar in volume over the coming years, their main focus has been on LNG as a way for shipowners to comply with the increasingly stringent restrictions on atmospheric emissions from ships. At the same time, the new standard also leaves room for the use of alternative low flash point gaseous or liquid fuels in marine propulsion systems.
