Abstract

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.

Abstract

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.

Abstract

Transportation oil and gas mostly used pipelines transportation. The condition of a pipeline must be continually monitored to ensure that defects do not cause it to fail and operate optimally. Pipeline has the possibility to experience defects during operations such as general corrosion, fatigue, crack, and others. Defects that occur in the pipeline during operation have serious consequences including loss of property, personal injury, or even loss of lives and serious ecological pollution. Awareness of the importance of conducting pipeline monitoring and safety issues for workers and residents around the pipeline site, emphasizes the importance of developing a technology for conducting pipeline monitoring activities in real time. The new technology for detecting metal defects is by using piezoelectric material. Based on laboratory scale, piezoelectric sensor can be applied to monitor pipeline defect. However, it is necessary challenges to scaling up in real application are following: (1) financial investment, (2) human behavior surrounding pipeline area, (3) receiving signal in long distance, (4) protection of piezoelectric sensor, (5) combination survey for future development.

Abstract

Maintenance is one of the important things to maintain a company in the industry. A company, such as LNG production company, must be able to produce and meet energy needs independently to support all operations, such as cooling water system that functions to control the temperature and pressure so that the production process runs optimally. If this system is disrupted, there will be excess use of water, waste water, and energy costs needed which result in higher total operational costs. With good and right care, it can reduce all risks posed. One component that plays a role in the cooling water system is a pump. This pump serves to flow the cooling water which is seawater to the LNG industry plant. At present, the amount of Work Order data recorded from the problems obtained from the pump requires maintenance updates. In this study, the method in the maintenance programs are used based on the Reliability-Centered Maintenance (RCM) implementation. RCM will increase cost efficiency, reliability, pump uptime, and propose maintenance tasks. Beside pump, the reviewing also involve supports components that affect pump optimization. In this paper, the functions, causes, and effects are identified and the new scheduled maintenance tasks are shown.

Abstract

Pressure relief device serves to control and limit the pressure by directing the flow into an additional path. In the process of purification of oil and gas, application of PRD are found in production gas separator system. However, based on API 581, the PRD also has a risk of failure that every oil and gas company needs to conduct regular inspections to ensure the reliability of PRD. One approach to evaluating critically the PRDs for arranging and scheduling programs is to use the risk-based inspection (RBI) method. The RBI is a systematic approach to the method of inspection management of equipment or works unit based on the level of risk that the equipment or work units. Risk assessment for production gas separator system’s PRD has based on API RP 581 third edition. After knowing the level of risk for PRD, the risk needs to be evaluated. For acceptable risk, it can be used as a reference to determine the next inspection until risk target. Meanwhile, unacceptable risk should be inspected immediately after RBI analysis.

Abstract

RBI analysis for heat exchanger tube has been explained by API 581. Two types of PoF determination using statistical data is provided to determine the PoF category. Both Weibull parameter and generic failure frequencies are the methods that will be analysis in this present study. PoF determination using Weibull distribution gives the exponential value of PoF in a certain of time. This method only consider failure modes and the failure rate of heat exchanger tube without considering possible active damage mechanisms in the tube. However PoF determination using generic failure frequencies gives more complex consideration. It considers not only failure and possible active damage mechanism, but also the effect of management system facilities of the heat exchanger on the integrity of the plant.

Abstract

PHE – ONWJ platform personnel found 93 leaking tubes locations in the fin fan coolers/ gas-cooling heat exchanger. After analysis had been performed, the crack in the tube strongly indicate that stress corrosion cracking was occurred by chloride. Chloride stress corrosion cracking (CLSCC) is the cracking occurred by the combined influence of tensile stress and a corrosive environment. CLSCC is the one of the most common reasons why austenitic stainless steel pipework or tube and vessels deteriorate in the chemical processing, petrochemical and maritime industries. In this research purpose to determine the appropriate inspection planning for two main items (tubes and header box) in the gas cooling heat exchanger using risk based inspection (RBI) method. The result, inspection of the tubes must be performed on July 6, 2024 and for the header box inspection must be performed on July 6, 2025. In the end, RBI method can be applicated to gas-cooling heat exchanger. Because, risk on the tubes can be reduced from 4.537 m2/year to 0.453 m2/year. And inspection planning for header box can be reduced from 4.528 m2/year to 0.563 m2/year.

Abstract

Logistics costs for Main Distribution Material (MDU) of Low Voltage Switchgear Devices (PHBTR) increased from IDR 12.5 billion in 2023 to IDR 13.9 billion in 2024, alongside persistent delivery delays beyond the Service Level Agreement (SLA) standards (30 days for Sumatera and Jamali; 45 days for Kalimantan and Sulmapana). In 2023, 172 Detailed Contracts (8.35%) experienced delays, affecting 2,223 units (12.18%), while in 2024, 149 contracts (6.34%) were delayed, impacting 1,448 units (7.17%). The key challenge is developing a distribution allocation model that considers supplier cost differences and Unit Induk demand to improve transportation efficiency and reduce delays. This study applies a quantitative approach using internal secondary data from PT PLN Quarter III 2025, involving 17 suppliers and 22 Unit Induk. The Weighted Goal Programming method is employed to address multi-objective trade-offs between minimizing transportation costs and fulfilling regional demand. Modeling using LINGO software produced an optimal transportation cost of IDR 2,129,998,480 with zero deviation, indicating full demand satisfaction. Compared to the initial allocation cost of IDR 2,704,828,480, the optimized model generated savings of IDR 574,830,000 (approximately 21.25%), particularly for the PL-250-2-LBS, PL-400-2-LBS, and PL-400-4-LBS variants. The proposed model offers a practical decision-making framework to control logistics costs and enhance service reliability..
