Six dual fuel Gas Turbine Generators (GTG) are used to generate power in the Banyu Urip oil production facility. The fuel gas system started to experience multiple challenges starting from unreliable Fuel Gas Compressor (FGC), fuel gas valve problem, and off-spec fuel gas due to scale formation at tube-bundle of Acid Gas Removal Unit Wet Surface Air Cooler (AGRU WSAC). Those multiple issues in the fuel gas system caused frequent use diesel fuel for GTG thereby increasing GTG’s operation cost. This paper shares how an integrated approach can deliver significant diesel fuel reductions by thorough surveillance, improving operational procedures and eliminating reliability issues. Root cause analysis was carried out on each issue that caused an upset in the fuel gas system, afterwards action items were assigned to several departments. With excellent collaboration between Engineering, Operations, and Maintenance, the improvement plan was successful. Our result shows a nearly 50% reduction in diesel fuel consumption in 2021 compared to the previous year.
