摘要

管中管(PIP)系统具有良好的结构阻力和有利的隔热能力,已广泛应用于深水石油和天然气开采。本文利用 OrcaFlex 软件开发了用于深水 J-lay 作业的 PIP 系统简化等效数值模型,以评估外管和内管在水动力载荷和铺管船运动共同作用下的动态响应。对本等效模型和其他现有 PIP 模型的机械响应进行了比较,以验证其合理性。考虑到船只运动、管道与土壤相互作用、波浪和水流,从弯矩、有效拉力、等效应力和应变等方面评估了内外管道的动态行为。随后,系统研究了关键几何参数对 PIP 系统动态特性的影响,包括外管和内管的直径与厚度比以及核心厚度。研究结果将为采用深水 J-lay 作业的 PIP 系统的结构设计和安装分析提供很好的指导。

Evaluation of dynamic behaviour of pipe-in-pipe systems for deepwater J-lay method

The pipe-in-pipe (PIP) system, with good structural resistance and favourable thermal insulation capacity, has been extensively applied in oil and natural gas exploitation in deep waters. In the present paper, a simplified equivalent numerical model of the PIP system for deepwater J-lay operation was developed to evaluate the dynamic response of the outer pipe and the inner pipe under the combined hydrodynamic load and pipelay vessel motion by the software OrcaFlex. The comparison of mechanical responses between the present equivalent model and other available PIP models was performed to verify its reasonability. Considering vessel motion, pipe-soil interaction, wave and current, the dynamic behaviour of the outer and inner pipes was evaluated on aspects of the bending moment, effective tension, equivalent stress and strain. After that, the influences of key geometric parameters on the dynamic behaviour of PIP systems were systematically studied, including the diameter-to-thickness ratios of the outer pipe and inner pipe as well as the core thickness. The findings would provide good guidance for the structural design and the installation analysis of PIP systems using the deepwater J-lay operation.
