【摘要】 阐述液化天然气运输船蒸发气再液化的必要性,分析再液化技术原理和再液化系统。对传统蒸汽动力装置船舶和带再液化装置的低速柴油机动力装置船舶分别进行燃料费用、LNG消耗费用、维修保养费用、设备投资比较计算,得出每年节约费用、动力装置投资节约费用、提高运输量等重要参数,并在经济性上给予了充分论证。对再液化装置的可靠性方案进行分析和探讨,实际数据证明液化装置装船后具有很好的环保性。更多还原

【Abstract】 The necessity re-liquefaction of the BOG in LNG cargo in LNG carrier,the principle of re-liquefaction technology and re-liquefaction system were introduced.The economic evaluation was carried out to the LNG carrier without re-liquefaction plant or with it by using a diesel power plant respectively.The fees of fuel,LNG loss,repairing and maintenance,as well as the investment of re-liquefaction plant were calculated to obtain some important parameters of vessel saving per year,power investment saving and the increase of transport and so on.The economy,safety,feasibility and environment protection of the re-liquefaction plan were discussed.更多还原
