海底天然气管线泄漏模拟及安全影响分析

The Numerical Simulation and Safety Analysis on Leakage of Subsea Gas Pipeline

海底天然气管线泄漏发生后,由于天然气的扩散特性以及天然气和水较大的密度差,可能会对周边通航船舶、救援、修复设备产生安全影响。有必要针对海底天然气管线泄漏扩散开展动态模拟研究。本文利用FLUENT软件对海底天然气管线泄漏扩散动态进行模拟研究,并根据模拟结果开展安全影响分析。分析结果对水面船舶和水下机器人的航行安全提供一定的参考和帮助。

Due to the diffusion characteristics of natural gas and density difference between natural gas and sea water,the occurring of subsea gas pipeline leakage will impact the safety of ships and equipments.It is necessary to simulate the leakage and diffusion of natural gas from subsea pipeline.In this paper,the FLUENT software is used to do the numerical simulation work.The safety analysis is carried out according to the simulation results.The analysis results can provide some help for the safety of the ship and remote operated vehicle.
