摘　　要：基于最新的HCSR规范,对一种典型超大型油船的破损剩余承载能力进行了相关的研究工作。首先对比计算分析了现行各规范分别在搁浅和碰撞工况下的破损范围;利用有限元计算了破损油船的剩余极限强度,并与规范计算极限载荷比对分析。研究结果表明:该油船各工况下安全系数满足规范强度要求且新规范下船体梁剩余强度安全性校核更加严格。Based on the damaged residual carrying capacity of latest HCSR specification and a typical super-large tanker,the damage range of the current specifications under grounding and collision conditions is compared and analyzed.The residual ultimate strength of the damaged tanker is calculated by finite element method and compared with the ultimate load calculated by the code.The results show that the safety factor of the tanker meets the requirements of the code strength under each working condition and the safety check of the residual strength of the ship body beam under the new code is more strict.
