小型液化气船结构设计

Structural Design of Small Liquefied Gas Carrier

小型液化气船机动灵活、支线调度周转快、受航道水位和桥梁净空等条件的制约小,可用于装载极低温的易燃化学品,发展前景广阔。通过解读IGC Code和船级社对液化气船的规范要求,剖析关键技术,以22000m^3 C型双耳罐液化气船为载体,从5个方面讨论该船的结构设计,为同类船型的设计提供参考。

Small liquefied gas carriers are maneuverable in navigation, flexible in feeder scheduling, seldom restricted by water depth and bridge clearance, and suitable for transporting flammable chemicals of extremely low temperature, so there are broad prospects for development. The key technologies for the kind of ship are analyzed through interpretation of IGC Code and the rules & regulations of the classification societies. A 22 000 m 3 liquefied gas carrier with type C bi-lobe tank is taken as the target ship to discuss the structural design from five aspects, in order to provide reference for the design of similar ship types.
