12000m^(3) LNG加注船液货舱初步设计分析

Analysis of Preliminary Design of Cargo Tanks of the 12000 m^(3) LNG Bunkering Vessel

针对中国海油计划建造的12000 m^(3)LNG运输加注船,结合LNG加注船技术特点及国际现有和计划建造的LNG燃料动力海船情况,对液货舱的舱容确定、型式选择、材料选择、设计蒸汽压力确定等方面进行分析,形成12000 m^(3)LNG运输加注船的液货舱基础参数方案,同时分析液货舱罐体尺寸初步选择及优化需要考虑的因素,为后续液货舱进一步设计提供技术基础。

Focusing on the 12000 m^(3) LNG bunkering vessel planned to be built by China National Offshore Oil Corporation(CNOOC),based on the technical characteristics of LNG bunkering vessels and the situation of existing and planned international LNG fuel-powered seagoing vessels,the determination of tank capacity,type selection,material selection and determination of design vapour pressure for liquid cargo tanks were analyzed,so as to form a basic parameter plan for the liquid cargo hold of the 12000 m^(3) LNG bunkering vessel.At the same time,the factors to be considered in the preliminary selection and optimization of the size of the cargo tank were studied,which can provide a technical basis for further design of the cargo tank of the LNG bunkering vessel.
