摘要：

海洋管线在海洋工程装备中应用广泛,在黑暗未知的海底极易受到船锚、深潜器等水下结构物的意外破坏,开展海洋管线平衡位形状态监测研究可有效保障管线的安全.本文基于逆有限元法开发了海洋管线在三维背景洋流作用下的位移场反演模型,包含输入参数模块、坐标转换模块和位移重构函数模块,考虑了悬链线型海洋管线曲率大、三向耦合大位移、局部翻转等特征,解决了三维背景洋流作用下悬链线型管线位移场低模态、不规则给位移场反演带来的技术难题,研究了监测点数量和监测点布置位置对位移场反演精度的影响.测点间距100 m、30° 布置的方式可满足工程精度要求,研究结果可为海洋管线健康监测系统设计提供一定的思路和方法.

Abstract:

Marine pipelines are widely used in offshore engineering and are highly vulnerable to accidental damage caused by underwater structures such as ship anchors and deep-sea submersibles, especially in the dark and unpredictable marine environment. Research on configuration monitoring of marine pipelines is essential to ensure their operational safety. This paper develops a displacement field inversion model for marine pipelines under the influence of three-dimensional background ocean currents, based on the inverse finite element method. The model consists of an input parameter module, a coordinate conversion module, and a displacement reconstruction function module. It takes into account key characteristics such as large curvature, three-dimensional coupling with large displacements, and local flipping behavior. The proposed approach addresses the technical challenges associated with low-order deformation modes and irregular displacement patterns. The impact of the number and layout of monitoring points on the accuracy of displacement field inversion is studied. The results show that the layout with a monitoring point spacing of 100 m and an angle of 30° can meet the engineering accuracy requirements. The findings of this paper can provide valuable insights and methods for the design of marine pipeline health monitoring systems.
