基于IGC 2016的支线LNG船破舱稳性优化设计研究

Research on Optimizing Design of Damage Stability of Feeder LNG Carrier Based on IGC 2016

对12 000 m^3支线LNG船的市场和总布置进行简要介绍,对比《国际散装运输液化气体船舶构造与设备(IGC)规则》新旧版本在破舱稳性上的变化以及在12 000 m^3支线LNG船上的应用,探讨其对实船的影响;通过改变案例船舶的总布置、初始工况和开口位置来改善该船的破舱稳性,使其满足新IGC要求。

The market and general arrangement of 12 000 m3 LNG carrier is introduced.By comparing the difference between the old and new IGC on damage stability and their applications on 12 000 m3 LNG carrier,the paper discusses their effects to ships.By changing the arrangement of water ballast tanks,initial conditions and position of openings,the damage stability of 12 000 m3 LNG Carrier is optimized so that it can meet the requirement of new IGC.
