To meet domestic demand, Indonesia has pipelines spread across many regions, which indirectly increases the risk of failure in certain pipeline segments. The consequences that occur as a result of these failures can be in the form of environmental pollution, financial loss, material failure for the company, even endangering the lives of the people around the pipeline. By implementing good operational risk management, security and safety in the oil and gas industry can be guaranteed and prevent fire incidents that can endanger lives and the surrounding environment. Based on this background, this undergraduate mandate is made in the form of a case study that focuses on the risk assessment of pipelines using the Muhlbauer method and API RP 581. In this thesis defense, an analysis will be carried out on a 26-inch offshore pipeline in the Jakarta Bay area that carries natural gas. The risk assessment was carried out using a semi-quantitative method following API RP 581 and modified by Muhlbauer 2015. From the analysis results, there is only one segment with a green risk level, two segments with a yellow risk level, two segments with an orange risk level, and three segments with a red risk level. In addition, based on parametric study, an increase in operating pressure will have a significant effect on the area consequences of small and medium-sized leak holes and will not have any effect on large-sized leak holes.
