受限空间跨接管吊装作业仿真模拟研究

Research on Simulation of Lifting Operations for Cross-Pipeline in Confined Spaces

摘要: 受航路上船舶安全通航作业全需要，通航区内水下油气生产设施需安装在泥面下的钢圆筒内。水下设施的前期安装、后期维护均需潜水员进入钢圆筒内部施工。钢圆筒内为受限空间，且设备密集，跨接管吊装作业存在较大安全风险。为验证设计方案可靠性，同时降低施工风险，可利用仿真模拟系统进行跨接管在受限空间内的施工演练。本文以锦州25-1油田西1井区钢圆筒内受限空间为模拟作业环境，详细阐述了受限空间水下生产设施跨接管吊装作业仿真建模方法，包括跨接管水动力模型、跨接管与基盘接触相互作用模型、吊装作业装备运动模型等。

Abstract: In order to ensure the safe navigation of vessels on the navigation route, underwater oil and gas production facilities in the navigation area need to be installed in steel cylinders beneath the mud surface. The initial installation and subsequent maintenance of underwater facilities require divers to enter the interior of the steel cylinder for construction. The interior of the steel cylinder is a confined space with dense equipment, and there are significant safety risks associated with cross-pipeline lifting operations. To verify the reliability of the design scheme and reduce construction risks, a simulation system can be utilized to conduct construction drills for cross connection in confined spaces. This article takes the confined space inside the steel cylinder in the West 1 well area of the Jinzhou 25-1 oilfield as the simulated operating environment and elaborates in detail on the simulation modeling methods for the cross-pipeline lifting operations of underwater production facilities in confined spaces, including the hydrodynamic model of the cross-pipeline, the interaction model between the cross-pipeline and the base plate, and the motion model of the lifting operation equipment.
