The development of a risk-based maintenance flowchart to select the correct methodology to develop maintenance strategies of oil and gas equipment

Abstract

There are hundreds, even thousands of equipment that are installed on an Oil and Gas Plant. The equipment can be static equipment, rotating machinery, or protective devices. Each type of equipment has a unique failure mechanism and failure mode. Maintenance tasks should be performed to prevent these failures from being happened. The maintenance task should be developed based on the methodology, which will capture the failure mechanism yet to prevent it from being more severe. Before March 2018, the Indonesian government has adopted a time-based maintenance policy for all static equipment operated by oil and gas companies operating in the Republic of Indonesia’s territory. Every three years, the static equipment that works must be inspected and recertified. In March 2018, the Minister of Energy and Mineral Resources issued regulation No. 18, which allows the use of risk analysis methods to determine maintenance strategies, known as risk-based maintenance, for all equipment operated by oil and gas companies operating in Indonesia. This paper will develop an initial flowchart to select the correct methodology to develop maintenance based upon the dominant failure mode. A case study to demonstrate the flowchart has also been performed in an Onshore Receiving Facility (ORF).
