HAZARD IMPLEMENTATION AND OPERABILITY STUDY (HAZOPS) IN THE PROCESS OF RISK ANALYSIS ON BOILER UNIT PEMBANGKIT TENAGA GAS DAN UAP (PLTGU) KERAMASAN PALEMBANG

Abstract

PLTGU Keramasan is a company engaged in electricity in South Sumatra with a total capacity of 1.082.12 MW. PLTGU Keramasan has an important component in power plant that is boiler, turbine and condenser. Boiler is part of PLTGU system as a water heater to drive turbines that generate electricity. Failure of the boiler may occur at any time leading to the cessation of the generating unit, so risk analysis is needed to identify risk assessment and risk evaluation with the Hazard and Operability Study (HAZOPS) method. The method of hazard identification and HAZOPS risk is syestematically review the process of the system and to determine the deviations that may lead to undesirable events.This research use qualitative design and presentation of data in the form of HAZOPS worksheet table. The result of risk analysis using HAZOPS method in PLTGU boiler is high and extreme risk on each node causing leaking boiler and fire. It can be concluded for tackling hazards are routine calibration of the transmitter, redundant transmitter,  instalation of pressure alarm and emergency responce plan (ERP) on boiler area
