Analytical Hierarchy Process Method to Engineering Companies Selection for Remaining Life Assessment of Oil and Gas Equipment and Installation in Indonesia

Oil and gas industry has an important role in receiving state revenues and national energy endurance. Equipment and installations are the main components of the oil and gas processing. Safety, security and reliability of equipment and installation guarantees must be maintained to realize safe, effective, efficient and reliable. Safety inspection of operating equipment and installations can be conducted periodically based on a certain period or the results of a risk analysis. ESDM Regulation No. 18 of 2018 concerning Safety Inspection of Installation and Equipment in Oil and Gas Business Activities, states that equipment and installations that have exceeded the design life span can still be used after evaluating the remaining life assessment and are declared to have extended service life. The evaluation of the remaining life assessment can be carried out by the Engineering companies which already has a permit from the Director General of Oil and Gas. This research uses the AHP method to determine which engineering companies will be selected to carry out work the remaining life assessment of oil and gas equipment and insulation. Criteria and sub-criteria are taken from journal references which are then validated by experts from inspection service companies, associations, academics and oil and gas companies.
