碰撞和搁浅是大型船舶事故的主要占比之一，在发生碰撞和搁浅事故时通常伴有破舱浸水，破损稳性不满足要求的船舶存在发生倾覆的危险，严重危害船上人员生命安全。因此，大型船舶的稳性研究是船体设计的重点和难点之一。本文基于船舶时域破损稳性的数值预报方法，以某大型船舶为例，利用时域破损仿真CAE软件Proteus对在危险工况下的时域破损进行研究分析，探讨了利用横贯进水舱室改善船体破损稳性的可行性和应用效果，给出能够提升破损稳性安全的舱室布置优化方案，为后续船舶的自主研发和创新提供技术手段。
Collision and grounding consist of the majority of large ship accidents, where flooding occur due to damaged compartments. Ships with insufficient damage stability have the potential risk of capsize, which severely harms the life safety of people on board. Therefore, stability analysis is one of the key points and difficulties for the general design of the large ship. Based on the numerical method for time domain ship damage stability simulations, taking a large ship for example, this study uses the CAE software Proteus imported from abroad to perform the time domain damage stability analysis of the target ship under critical conditions, and discusses the feasibility and effect of the cross-flooding tank to improve the damage stability. The optimized compartment design layout is proposed, which provides the technical tools for the self development and innovation of subsequent ships.
