Risk Mitigation of Buried High Temperature Gas Pipeline Construction

Natural gas is selected as transition energy to achieve net zero emissions. Gas pipeline construction is developed in accordance with Sustainable Development Goals on Industry, Innovation & Infrastructure, Clean & Affordable Energy, and Climate Action. The potential risk of the heat transfer process from the pipeline to the ground surface temperature can create a potential hazard that can cause pain/injury to human skin if it exceeds the pain threshold temperature. This study aims to investigate the best method for risk mitigation of heat transfer from gas pipelines to the ground surface, through alternative solutions such as burial deepening options, insulation options, or air cooler at well site options. These options are studied as part of the risk mitigation strategy for the buried high-temperature gas pipeline construction. These risk mitigation options consider technical and economic feasibility studies at the conceptual stage presented in this study to identify the best option to mitigate the potential injury risk to humans. The result with a buried insulated pipeline is the best option for controlling heat transfer compared to the air cooler option. The constructability of burial deepening up to 8 m is not feasible, especially the 6m depth of the groundwater table observed.
