Redesign Support dan Analisis Tegangan Pada Sistem Perpipaan Line Gas Sales Receiver akibat Soil Settlement

Abstract

Abstract – The gas sales receiver piping system in one of the companies engaged in the oil and gas industry is experiencing a problem of soil subsidence on the support. The subsidence on the support has resulted in a reduction in pipe support. Due to the reduced pipe support, stress analysis needs to be conducted, and the repositioning of the supports based on the stress analysis results is necessary. After the stress analysis, the highest sustained stress value obtained from the software is 31,860.9 psi with a ratio to the allowable stress of 159.1%. After the repositioning is done, a reanalysis is conducted in the software, and the stress value obtained is 14,363.7 psi with a ratio to the allowable stress of 71.8%. From these results, it can be confirmed that the pipeline system with the new supports can function properly.
