Safety is an important aspect of the industrial process. Failure of system and mechanism endanger both human and environmental safety. Safety is obligated to be implemented precisely and thoroughly to prevent failure consequences. One of the preventive implementations is to map out safety devices in the form of SIS (Safety Instrumented System) and other layers of protection. However, to acknowledge this safety device performance used SIL (Safety Integrity Level). This final research is intended to analyze Fuel Gas systems on Onshore Receiving Facilities (ORF). HAZOP (Hazard Operability Study) as process hazard analysis with deviation during the operation so that the risk level is known. SIL verification towards SIL target is SIL-2 refer to IEC 61511 standards by FTA (Fault Tree Analysis) method. From the HAZOP study can be concluded that over-pressure becomes a top hazard to all nodes due to the most severe consequences, the highest likelihood (medium risk). The calculation result of PFDavg is Node 1 (Fuel Gas Scrubber V-6060) is 6,22E-03, Node 2 (Fuel Gas Filter Separator S-6060A) is 1,24E-03, Node 3 (Fuel Gas Filter Separator S-6060B) is 1,24E-03, Node 4 (Fuel Gas Superheater E-6060) is 1,21E-03, and Node 5 (Instrument Gas Receiver V-6070) is 2,23E-03. The conclusion of this research shows that five components of the Fuel Gas System fulfill the SIL-2 target, therefore, doing a re-design to add a safety device is unnecessary.

In the oil and gas industry, the purification and handling of oil and petroleum gas, the cycle of warmth transformation is expected to isolate the H2S and CO2 from natural gas with an amine. The cycle happens inside the amine reboiler which is a shell and tube heat exchanger type. Cycle liquid streaming in the Amine Reboiler are Lean Amine on the shell side (HEXSS) and Therminol-55 on the cylinder/tube side (HEXTS). With such synthetic arrangement, worked with high weight and temperature, makes the liquid into a destructive climate for Amine Reboiler. Along these lines, an exact review and planning program is needed to guarantee equipement’s life, guaranteeing the protected establishment and wellbeing of laborers. Thus, it is important to direct a danger assessment for shell and tube heat exchanger gear utilizing the Risk-Based Inspection technique which alludes to the API RP 581. The danger of Amine Reboiler is a mix of the Probability of Failure (PoF) and the Consequence of Failure (CoF). From the PoF and CoF acquired, the HEXSS hazard level on the danger lattice at the RBI date and RBI plan date are ordered as Low Risk and Medium Risk. While the danger level of HEXTS on danger network at RBI date and RBI plan date both are ordered as Medium-High Risk. At that point the prescribed date to do the assessment is January 1, 2020.

The process of natural gas into LNG (Liquefied Natural Gas) requires many steps and various types of chemical products. The process also produces waste. The Liquid Incinerator treats waste from LNG process. This unit often experiences damages which causes the plant do not work properly and even a down/trip problems due to the continuous operation and the absence of maintenance program, especially for rotary equipments. This causes environmental pollution because the waste is unprocessed and could have an impact on the increased cost to treat the waste elsewhere. One of approaches to analyze the causes of the damage, the impact and effective treatment for equipment is using Reliability Centered Maintenance (RCM). The RCM method is expected to be able to identify the primary and secondary functions of the system, possible failure function, Failure Mode and Effect Analysis (FMEA), and the maintenance actions on the plant. The FMEA result will be used to determine the proposed maintenance task. Based on the proposed maintenance task, the maintenance interval for each equipment is obtained. After RCM analysis is done on 4 equipments, liquid waste feeding pump (34-G-2), quencher pump (34-G-3), scrubber pump (34-G-4) and air compressor (34-K-4). For 34-G-2 failure mode, requires 78% preventive maintenance and 22% corrective maintenance, 34-G-3 requires 87% preventive maintenance and 13% corrective maintenance, 34-G-4 requires 87% preventive maintenance and 13% corrective maintenance and 34-K-4 requires 70% preventive maintenance and 30% corrective maintenance. Workpackage for each interval is created from every failure mode for each interval for maintenance / inspection.

The gas central processing plant as a facility used to process natural gas had a variety of components that were so complex and many in number. To reduce the risk of failure of these components it was necessary to carry out maintenance. But it would be very inefficient if all the components were treated at the same level, considering that there were so many and the human resources that were owned were very limited. Therefore, in taking care of these components it was necessary to prioritize them according to their critical level. In this research, in determining the critical level of a component using risk-based methods according to the available standards, namely NORSOK Z-008. By making a hierarchy and asset level register of all components, then the value of the probability rating and consequence rating was determined. So that the criticality ranking of each component was obtained according to the criticality risk matrix that was converted from the company's risk matrix, so that the critical level of the component was obtained in the levels of H (high), M (medium), and L (low). With the critical level of this component, the company did not need to take care of all the components. In this research, there was 33 equipment with 140 subunits/subsystems, and the total number of components was 674. Of the 674 components as many as 28 components had a critical level of H (high), 192 components had a critical level M (medium), and 454 components had L critical level (low) of each critical level that has been obtained, it is not necessary to carry out maintenance with the same level to all components. In this research, every component that has H (high) criticality level will be treated as a Preventive Maintenance, while a component with a critical level of M (medium) will be Preventive Maintenance if needed, and a component with L critical level (low) will be treated Corrective Maintenance.
