Deepwater Gas Pipeline Leak Numerical Simulation Study
Abstract: This paper presents the numerical simulation results for a subsea gas pipeline release, which was designed to expert high pressure nature gas from Deepwater offshore platform to the onshore re-ceive terminal. 32 leak scenarios were simulated using OLGA® and concluded the initial leak rate, leak duration and released mass weight in 4 water depths, 3 hole sizes and 2 flow rates. The re-search assesses the influence of subsea pipeline’s elevation, riser inventory, subsea safety isolation valve, external hydraulic pressure, leak detection, emergency shutdown and blowdown from onshore terminal. The research results could be used as critical input for the further risk analysis and emergency preparedness analysis meanwhile could be the important technical support to emergency response and mitigation actions.
