基于全耦合时域模型的J型铺管管道内力敏感性分析
|
摘要
通过建立船体-托管架-管道的全耦合动力定位模型,在海洋环境荷载作用下,开展J型铺管动力全耦合时域反应分析,对影响海底管道J型铺设的因素,包括管道初始铺设角度、管道尺寸、水深以及环境荷载等进行了探讨。结果表明:初始倾角和荷载方向是对管道受力影响最大的两个因素,在管道铺设过程中要尽量避免逆向及横向铺管;管道湿重越大,等效应力越大;波浪荷载对管道影响很小,基本可以忽略。
A coupling model of vessel,stinger and pipeline is developed combining the dynamic position system.The dynamic analysis of fully coupled J-pipelay system in time domain is conducted,which subjected to the ocean environment loads.The factors affecting the J-lay submarine pipeline such as the initial pipe laying angle,pipe size,water depth,wave and current loads are discussed.The initial pipe laying angle and direction of environment loads have the most significant effect on the pipeline response during pipelay.Meanwhile,J-lay pipelay in the transverse and reverse directions to the incoming wave and current should be avoided.The von Mises stress increases with the increasing submerged weight of pipe.The effect of wave load on J-pipelay is small,so it can be ignored.
