Hazard and Operability (HAZOP) Study at Separation System in the Offshore Platform

Energy is needed to maintain the cycle of life. It could come from natural oil and gas. Energy sources (oil and gas) are obtained by mining activities on land or sea. At sea, the offshore platform plays very important function in the exploration of natural oil and gas. It consists of several systems; one of these systems is a separation system, which is useful for separating oil, gas and water from the hydrocarbon stream. The separation system consists of several types of equipment such as separators, filters, pumps, pig launchers, and others. Therefore, it is necessary to carry out periodic maintenance activities for equipment on the offshore platform. Maintenance activities could be carried out by knowing the risk level of each equipment on the offshore platform. This research uses the hazard and operability study in order to determine the level of risk in each equipment in the offshore platform as a case study. After the risk level is obtained, the intensive maintenance activities can be carried out on the equipment that has the highest risk level. In this research, it is known that the two types of separators have the highest risk level. Therefore, intensive maintenance activities should be carried out on the two equipments.
