In December 2019 XMAN oilfield experienced problems with oil production loss due to several factor of surface facilities problem: leakage of subsea pipeline, power supply problem, etc. This incident had a negative impact on the performance of PEP Asset 3 caused the production target not to be achieved, increased maintenance costs, and lead environmental issue. Based on production data record 2020-2021, there were top 3 surface bad actor identification that caused an contributor of oil loss production. The surface bad actor could classify into 3 categories: leakage of 12” subsea pipeline MOL XAP - BLG, GTG 1A & 1B problem, and leakage of 12” subsea pipeline MOL XMA-XAP. To find the root cause and the most dominant factor of the problem, the researcher carried out Fishbone diagrams and Failure Mode Effect Analysis (FMEA) combined with Pareto diagrams. By using the value-focused thinking method, the researcher and the team in the focus group discussion develop alternatives that can be implemented to achieve the fundamental objectives that have been set. There are 4 alternative solutions can be used to solve this problem: Segmental replacement of 6 Km 12-inch subsea pipeline from XAP to MOS Balongan, Total replacement 28 Km of 12-inch subsea pipeline from XAP to MOS Balongan, Chemical Continues injection, Rent a floating production storage and offloading (FPSO) unit. This research will use the Analytical Hierarchy Process (AHP) method to determine the best solution. Based on the results of the interviews obtained 3 criteria in the value tree. The criteria are in the form of Cost, Benefit, and Risk. The Cost criteria has 2 sub-criteria, namely the capital cost and operation & maintenance cost. the benefit criterion has 4 sub-criteria consisting of operation ability, maintainability, oil gain and Installation time. And the last criterion is risk, that has 1 sub-criteria: potential of hydrocarbon release or oil spill. The calculations using the AHP methods obtained the Segmental replacement of 6 Km 12inch subsea pipeline from XAP to MOS Balongan become the best solution.
