Abstract
Nowdays, theusage of natural gas is very popular in the power plant industry compared to coal and oil. In 2016, natural gas-fired generators accounted for 42% of the operating electricity generating capacity in the United States. The use of natural gas is considered to be environmentally safe than coal and oil. Natural gas emits 50 to 60 percent less carbon dioxide (CO2) when combusted in a new, efficient natural gas power plant compared with emissions from a typical new coal plant. Besides, the natural gas power plant has an efficiency of 53% when combined. PT Nusantara Regas has an Onshore Receiving Facility (ORF) to flow the gas produced from the regasification process in the Floating Storage and Regasification Unit (FSRU) to three Power plants. One of them is PLTGU Muara Karang which capacity of 630 psi and 350 psi. In 2017, PLTGU Muara Karang will increase electricity capacity through Muara Karang Peaker MKP) which is planned to be operational in March 2020. One of the equipment at MKP that used to fluida is piping. When operating, and there is a failure in the piping that can effect in a gas explosion or flammable, this is caused by corrosion, over pressure or other errors that can damage the facility to shutdown the plant. Based on the Regulation of Minister of Energy and Mineral Resources Republic Indonesi No.18, 2018 that every company engaged in the oil and gas processing industry must inspect on any equipment in the plan, which has a level of risk or failure that can affect the overall system performance. An accurate inspection and scheduling program is needed to guarantee the life of each equipment, ensuring the plant is safe and safe for workers. Therefore it is necessary to conduct a risk evaluation for Process Gas Piping equipment using the Risk Based Inspection (RBI) method that refers to API 581. RBI is a systematic approach to inspection management on static equipment according to the level of risk. The acceptable risk level is then made as a reference to determine the next inspection. Whereas for unacceptable risks mitigation efforts must be made.
In determining the risk ranking and inspections plan, the risk value is required, which is a function of the probability of failure and the consequences of failure, also requires risk targets from the company to determine when the next inspection will be carried out. The risk value based on the calculation of pipe 12” – PG – 06251 – C is 0,412162146 ft2/year and for pipe 2” – PG – 06255 – C is 0,412173420 ft2/year. Both of the pipes don’t exceed the risk target and for the inspection carried out on March 24th, 2023.
