Stress Analysis for GASCO Piping System

Established in 1978, Abu Dhabi Gas Industries Ltd. (GASCO) is the operating company responsible for processing the natural and associated gas produced from onshore oil operations in the Emirate of Abu Dhabi. The project aimed at conducting a stress analysis to determine the causes of flange gasket leakage in Units 391, 392, 393, and 394 of the Habshan Gas Processing Facility owned and operated by GASCO.
The analysis was carried out using the pipe stress analysis software CAESAR II, with due consideration of Process Piping Code B31.3 of the American Society of Mechanical Engineers (ASME). The analysis covered an assessment of the adequacy of pipe supports, as well as an investigation as to whether there were excessive piping system loads at flange locations.
The project was concluded with a stress analysis report covering the four units (a total of 32 process lines). The report included rerouting recommendations for the piping system to resolve the leakage problem.
