Risk Assessment of Balikpapan-Samarinda Oil Distribution Pipeline Using Kent Muhlbauer Method

The planned relocation of the Indonesian capital city to East Kalimantan can lead to an increase in fuel consumption in the area, and to meet all these needs, a pipeline is planned to be built, to transport oil from the Balikpapan BBM Terminal to Samarinda and Palaran. The pipeline system is used for fluid transfer processes that are prone to damage where there are several potential hazards to pipelines and high costs for construction and maintenance, so it takes a lot of consideration in choosing the path to be built and risk assessment of the selected path. This study aims to select an alternative oil distribution pipeline, then identify hazards, analyze frequency, consequences, then represent risks and analyze mitigation efforts in overcoming the damage to the oil distribution pipeline. On alternative pipeline selection, the Analytical Network Process method is used. Alternative 5 was chosen, with combines of segment 1A (onshore), toll segment, Palaran segment, and Samarinda C segment. Then, for risk assessment, Kent Muhlbauer's model indexing method is used, and based on the results of risk representation by looking at the average relative risk score, which is 19 points when flowing gasoline, and 41 points when flowing gasoil, it is found that segments 3, 4, 2B, 1B, 1D, and 2A are the most vulnerable segments with a relative score below the average. After carrying out risk mitigation actions, it's found that the segments that are in a vulnerable condition exceed the average value of the previous relative risk score.
