摘　　要：为了对比新的散货船、油船协调共同规范和旧的双壳油船结构共同规范,选取两艘具有水平桁结构和两艘具有槽型舱壁油船作为研究对象,对这两种不同结构形式的油船,分别按HCSR和CSR规范的要求,进行加载分析计算疲劳寿命,并基于CSR规定,比较底边舱下折角位置处的疲劳寿命。认为HCSR疲劳载荷选取更加合理,评估体系更加严格。For comparing the two fatigue assessment system of oil tanks given by HCSR and CSR-OT, two oil tanks with hor- izontal stringer and corrugated bulkhead were selected as research objects. The hot spot stress FEA was carried out with two kind of different applied loads according to HCSR and CSR-OT respectively so as to calculate the fatigue life. The results of fatigue life of the hopper knuckle were compared, showing that HCSR has more reasonable loads and more strict assessment system.
