Abstract

It is well known that the installation loads during offshore pipeline installation are usually higher than the operation ones. FRP materials for offshore pipeline applications seems to be very promising due to their high strength, light weight, and excellent corrosion and fatigue resistance. However, during S-lay installation high bending stresses that may cause material failure or buckling take place. Due to the anisotropic nature of the multi-layered FRP pipelines, the permissible bending curvature is difficult to be estimated. Few published works have proposed the framework for bending stress calculations and have provided complex equations that is not convenient to be used. In the present work, an open numerical code in Mathematica® is offered for the first time. Numerical results for S-lay installation of representative pipelines are provided and commended.

海上s层玻璃钢管道安装的计算机辅助设计。开放规范第1部分:弯曲应力

众所周知，海上管道安装过程中的安装载荷通常高于运行载荷。玻璃钢材料用于海上管道的应用似乎非常有前途，因为它们具有高强度，重量轻，优异的耐腐蚀性和抗疲劳性。然而，在s层安装过程中，高弯曲应力可能导致材料失效或屈曲。由于多层玻璃钢管道的各向异性，其允许弯曲曲率难以估计。很少有已发表的著作提出了弯曲应力计算的框架，并提供了不方便使用的复杂方程。本文首次在Mathematica®中提供了一个开放的数字代码。给出了具有代表性的s层管道安装的数值结果，并对其进行了评价。
