基于局部线性化方法的瘫船稳性敏感性分析及衡准完善
Sensibility analysis and further development for dead ship stability criteria based on local linearization method
摘要
Abstract
[Objectives]The dead ship stability,which is defined as a ship losing its power and rolling after turning into beam seas,is recognized as a dangerous stability failure mode. The International Maritime Organization(IMO)and its sub-committee on Ship Design and Construction(SDC)are expected to finalize the second-generation intact stability criteria in 2019,while a number of sample calculations are currently required for its perfection.[Methods]In this paper,a Level 2 criterion for dead ship stability is conducted for three container ships based on the local linearization method.[Results]Ship design parameters which can influence the probability of capsizing are investigated,and it is concluded that a ship's capsizing probability may first decrease and then increase as draft increases. Besides,standard value for Level 2 criterion is proposed and several suggestions are raised for the improvement of IMO dead ship stability criteria.[Conclusions]This study has a certain value in engineering application and provides technical support for the further development of dead ship stability criteria.关键词
