深水S型铺管作业参数敏感性分析

摘要

The sensitivity of parameters of S-lay was analyzed based on lumped mass method, considering seabed, discrete stinger and current boundary conditions, neglecting damping, friction and torsion.The influence of water depth, pipe diameter, wall thickness, radius and length of the stinger on the mechanical properties of pipeline was analyzed, which provides a reference for the design of S-lay installation in deepwater.%基于集中质量法原理,考虑海床、离散型托管架和海流等边界条件,忽略阻尼、摩擦和扭转,分析水深、管径、壁厚、托管架半径和长度等参数变化对S型铺设管线力学性能影响的一般规律,为深水S型铺设作业设计提供参考.
