Abstract

Generator turbin gas merupakan salah satu peralatan penting dalam industri eksplorasi dan produksi minyak dan gas yang berfungsi sebagai sumber tenaga utama. Keandalan operasional Generator turbin gas sangat mempengaruhi kontinuitas produksi, sehingga diperlukan strategi pemeliharaan yang efektif untuk meminimalkan downtime dan biaya perawatan. Perawatan pada turbin gas dilakukan pada komponen kritis yang ditentukan dengan metode FMECA hingga didapatkan 2 komponen kritis dengan kategori very high – unacceptable yaitu gas filter untuk G-1201A dan inlet guide vanes untuk G-1201B. Metode age replacement dengan kriteria minimasi downtime juga dilakukan sebagai bentuk preventive maintenance yang dilakukan pada kedua komponen kritis dengan syarat memiliki karakteristik increasing failure rate (IFR). Interval pergantian pencegahan gas filter G-1201A pada hari ke 60 dengan downtime minimal 0,009591 dan nilai reliability 54,39%. Interval pergantian pencegahan inlet guide vanes G-1201B pada hari ke 74 dengan downtime minimal 0,0064123 dan nilai reliability 61,94%. Pemodelan parameter variabel proses untuk komponen gas filter G-1201A dan inlet guide vanes G-1201B dengan menentukan nilai average detection ditemukan sebesar 80 detection dengan parameter variable proses gas filter differential pressure dan 129 detection dengan parameter variabel proses intake air temperature.

Gas turbine generators are one of the important equipment in the oil and gas exploration and production industry that serves as the main source of power. The operational reliability of gas turbine generators greatly affects production continuity, so an effective maintenance strategy is needed to minimize downtime and maintenance costs. Maintenance on the gas turbine was carried out on critical components determined using the FMECA method until 2 critical components were obtained with a very high category – unacceptable, namely the gas filter for the G-1201A and the inlet guide vanes for the G-1201B.. The age replacement method with downtime minimization criteria is also carried out as a form of preventive maintenance carried out on both critical components on the condition that it has the characteristics of increasing failure rate (IFR). The interval of G-1201A filter gas prevention change on day 60 with a minimum downtime of 0.009591 and a reliability value of 54.39%. The interval of the inlet guide vanes G-1201B prevention change interval on day 74 with a minimum downtime of 0.0064123 and a reliability value of 61.94%. Modeling of process variable parameters for G-1201A gas filter components and G-1201B inlet guide vanes by determining the average detection value was found to be 80 detections with variable parameters of the process gas filter differential pressure and 129 detections with variable parameters of the process intake air temperature.
