摘要
船舶舱室强度试验一般在码头阶段进行,借助外界水的浮力和压强平衡强度试验产生的压力,以提高试验安全性,却也大幅延长了码头周期。文章以18600 m³LNG加注船为例,以有限元仿真计算为基础,开展坞内强度试验技术研究。通过分析选定坞内强度试验的目标舱室,策划强度试验方案,编制坞墩布置图,并借助有限元仿真计算验证坞墩布置的合理性,最终实现了干船坞下的舱室强度试验,为围护系统的提前施工创造条件,有效缩短LNG加注船整体建造周期。
Ship cabin strength tests are generally carried out at the dock stage.With the help of the pressure from the external water buoyancy and pressure balance strength test,it can improve the test safety.But it greatly prolongs the terminal cycle.The article takes the 18600 m³LNG bunkering vessel as an example and carries out the research on the strength test technology in the dock based on the finite element simulation calculation.By analyzing the target cabins of the strength test in the selected dock,planning the strength test plan,and preparing the dock pier layout plan,with the help of finite element simulation calculations to verify the rationality of the pier layout,the cabin strength test under the dry dock is realized finally.It creates conditions for the advance construction of the containment system and effectively shortens the overall construction cycle of LNG bunkering vessels.
