IMO第二代完整稳性衡准对现有万箱船设计的影响

国际海事组织（IMO）正在制定基于水动力学的第二代完整稳性衡准，新衡准的实施必然对现有船舶的设计带来巨大影响。集装箱船大型化是航运界的发展趋势，万箱船船型订单近年也大幅上升。已有的事故发现大型集装箱船对参数横摇、过度加速度等衡准相对敏感，但现有船舶的设计对此类事故模式考虑较少，因此有必要开展相关研究。本文选取了某万箱集装箱船，对其大量装载工况进行四种稳性失效模式的计算分析，研究了第二代完整稳性的实施对大型集装箱船的稳性影响，并对其装载、设计等提出一定的建议。

Study of the Effect of IMO Vulnerability Criteria of Second Generation Intact Stability on the 10000TEU Container Ship

The Vulnerability Criteria of Second Generation Intact Stability based on hydrodynamics are developed by IMO. The implement of the new criteria may cause effect on the design of existing ship. Container ships have been getting bigger, and the number of orders is increasing in recent years. The accidents taken place show that the large container ships are sensitive to the criteria such as parametric rolling and excessive acceleration. Since the design of the existing ships seldom takes it into consideration, it is necessary to carry out relevant research. In this paper, four stability failure modes, including parametric roll, excessive acceleration, pure loss of stability and dead ship condition are calculated for a 10000 TEU container ship under lots of loading conditions. The effects of vulnerability criteria of second generation intact stability are studied, and some improvement recommendations for the design and loading conditions of the large container ships are put forward.
