新修订的IGC规则对37,500方LEG运输船破舱稳性的影响研究

提要：新修订的IGC规则对液化气船压载航行状态的破舱稳性提出了明确的要求,本文针对压载工况纳入破舱稳性计算中初始工况的问题,对江南造船(集团)有限责任公司自主研发的全球最大型液化乙烯气体运输船——37,5000方LEG运输船进行了破舱稳性方面的计算研究,得出了新要求对该船的破舱稳性计算结果的影响,并通过调整压载水装载方案,对不满足新修订的IGC规则的破舱稳性的工况作出了改进,并满足了这一新的基本要求,保持了江南造船在液化气船研发领域的技术领先优势,为公司后续接单做好了技术准备。

Research on Damage Stability of 37500m3LEG Carrier according to the Revised International Gas Code

The revised international gas code requires the damage stability calculation of ballast conditions of the liquefied gas carriers definitely. This paper, aiming at the damage stability calculation in the initial ballast conditions, computed and researched 37,500m3 LEG carrier, which was the world's largest LEG carrier and researched by Jiangnan Shipyard (Group) Co., Ltd. independently . Through the research and calculations, we concluded the impacts of the revised IGC requirements on the damage stability. By adjusting the loading of ballast water, writers had improved the ballast conditions which did not satisfy the rules of the revised IGC to meet the new basic requirements. This study not only maintains the leading-edge technology of Jiangnan Shipyard in the liquefied gas carrier research and development, but also makes a good technical preparations for follow-up orders in the future.
