摘要:
对于液化天然气(LNG)/柴油双燃料船舶,爆炸性、可燃性或有毒性气体的意外泄露和累积对船舶、人员和设备的安全存在极大风险。为保障20 000箱LNG/柴油双燃料远洋大型集装箱船在相对狭小的机舱空间里能有效地排放危险气体,对该型船的机舱通风系统进行优化设计与配置。首先根据本质安全型机舱的要求,给出本质安全型机舱通风系统总体设计方案;然后通过耗气量和通风量分析计算,给出机舱通风容量、主机供气管路及燃气阀组单元(GVU)通风容量、发电机管路及GVU通风容量、锅炉管路及GVU通风容量以及燃气处理间通风容量的计算及风机选型;最后给出LNG燃料供给系统主机供气管路和发电机供气管路,以及相应GVU通风配置方案。分析计算表明设计和配置的通风系统既能为主要设备提供足够的空气量,又能将危险气体量控制在安全范围内,保证船舶的正常安全运行。
Abstract:
For liquefied natural gas (LNG)/diesel dual fuel ships, accidental leakage and accumulation of explosive, flammable or toxic gases poses a significant risk to the safety of ships, personnel and equipment. In order to ensure that 20 000 tanks of LNG/diesel dual fuel ocean-going container ships can effectively discharge dangerous gases in relatively narrow cabin space, the cabin ventilation system of this type of ship is optimized and configured. Firstly, according to the requirements of the intrinsically safe cabin, the overall design scheme of the quality and intrinsically safety cabin ventilation system is given. Then, through the analysis and calculation of air consumption and ventilation, the calculation and fan selection of ventilation capacity are finished for the cabin, the main engine supply pipeline and its Gas Valve Unit, the generator pipeline and GVU, boiler piping and GVU, and gas processing room; finally, the configuration scheme of the main engine supply line, the generator supply line, and the corresponding GVU ventilation of the LNG fuel supply system are discussed. The analysis and calculation show that the designed and deployed ventilation system can not only provide enough air for the main equipments, but also control the amount of dangerous gas in a safe range to ensure the normal and safe operation of the ship.
