Pipeline systems are a vital transportation component in Indonesia's energy sector, given the large amount of investment in the exploration and production of crude oil, natural gas and condensate. As an important aspect, the integrity of the pipeline system must be maintained, which refers to the stable and uninterrupted condition of the pipeline so that it can optimally deliver resources at all times during the operational life of the pipeline. The existence of pipeline road crossings used for truck transportation routes is one of the conditions that can disrupt the integrity of buried pipes. This study was conducted to ensure the safety of buried pipelines at various crossing points. In this study, the buried piplines analyzed consisted of a gas pipeline, a condensate pipeline, and a water pipeline. The analysis consisted of crossing location assessment based on API RP 1102, stress analysis based on ASME B31.4 and ASME B31.8 codes by simulatiopn using AutoPIPE software, and quantitative risk assessment (QRA) based on BS PD 8010-3:2009+A1:2013. From the assessment conducted, it was concluded that the pipelines analyzed was safe at each of the crossing locations reviewed. The stress analysis results showed that the pipelines was safe, with a maximum code-based stress ratio of 0.85 for the gas pipeline at crossing #3. The risk analysis yielded the highest individual risk value of 3.60E-06 for the gas pipeline at crossing #4 and the worst societal risk criterion of Tolerable if ALARP for the gas pipeline at crossing point #4-#8. It is hoped that this research will be useful for future pipeline studies.
