A Fundamental Study on Damage Assessment of the 30-Inch Gas Pipeline

Oil and gas contribute significantly to achieving the growing demand for energy, which is rising in parallel with population growth. The pipeline system is the main transport system used in the distribution of oil and gas because the pipeline system is considered the most effective and efficient system. The distribution system for gas and oil must guarantee security and safety. Analyzing the pipeline is necessary to ensure distribution security and safety. In this study, a finite element analysis of the gas pipeline specimen was conducted. This analysis is carried out in two stages, first structural analysis and continued with damage analysis, where the damage used is a dent. In the dent analysis, environmental conditions are applied, namely non-pressure, pressure, and full pressure. Then assessed all the results of the analysis of each stage, the assessment was carried out by verifying the results of the analysis with the applicable standard rules. So that the characteristics of the pipeline can be recognized and work accidents caused by operating pipeline failure can be avoided.
