Risk Assessment of Subsea pipeline using standard DNVGL-RP-F107

To avoid fuel scarcity, exploitation activities must be carried out to meet the needs of oil in Indonesia. In the process of oil exploitation, facilities are needed to carry out a fluid transfer system from one place to another. One way to carry out the process of fluid transfer at an offshore location is the use of an underwater piping system. However, in the transfer of fluid from one place to another there is a danger that can cause failures in the pipeline system. For example, if an underwater gas pipeline is in the shipping lanes, international and national vessels, there is a possibility of danger that could occur due to a third party. In making this thesis the risk assessment is assessed using the DNVGL-RP-F107 standard. Based on the DNVGL-RP-F107 standard, hazards that may occur in underwater gas pipelines are hazards caused by falling or dropped anchors, anchored dragged pipes and destroyed ship (ship sinking). In risk assessment using the DNVGL-RP-F107 standard, the consequence analysis conducted refers to the damage to the subsea pipeline. After getting the analysis results from the index values that have been made, proceed with making a risk representation using the Risk Matrix. Pipelines that have been evaluated and representations in the risk matrix are in the ALARP zone (as low as reasonably practical) and in acceptable zone.
