Optimalisasi Schedule Maintenance Turnaround Hot Gas Path Inspection Turbin Gas Di North Duri Cogeneration Plant Menggunakan Metode Impact
North Duri Cogeneration Plant (NDC) is once of Chevron asset in IndoAsia
Business Unit. The NDC location is in Duri, Province of Riau, Indonesia. The
NDC has 3 units gas turbine and each unit has been combined with Heat Recovery
Steam Generator (HRSG). An unit gas turbine NDC is produce electricity of 100
MW. And 1 unit HRSG NDC is produce steam of 360.000 BCWEPD (Barrel
Cool Water Equivalent per Day). Hot gas path inspection (HGPI) is maintenance
activities gas turbine, which routine scheduled in NDC every 3 years per unit.
Maintenance schedule for turnaround HGPI gas turbine at NDC need to be
optimized. By optimized of HGPI maintenance schedule can be maximized work
plan, which is comply of 4 Key Performance Indicators there are Safety, Quality,
Schedule and Cost through Initiative for Managing PACesetter Turnarounds
(IMPACT). The result of optimal electricity production was increased by 13.174
MWh and the steam generated from units in NDC of mass total steam of 126.661
Mlbm and 371.827 BSPD (Barrel Steam per Day).
Key word: Maintenance, NDC, HGPI, IMPACT
