RELIABILITY IMPACTS ON THE AVAILABILITY OF TURBINE DRIVEN POWER GENERATION FOR OFFSHORE PLATFORM IN MALAYSIA

The availability and reliability have become the Key Performance Indicator (KPI) in drawing the line how good the turbine driven power generation system is performing particularly for offshore oil and gas productioin facilities. Availability is defined as the percentage of time that the equipment will be available to meets the customer requirements. The equipment availability requirements is typically set at 99.99% meaning that the power generatioin system is supposed to be running continuously throughout the year. The determination of the availability would very much depend on the reliability of the system. Reliability is a measure of the ability of the equipment to perform its function over a period of time and it is normally set at 99%. Thus, this paper investigates the impact of equipment reliability in terms of maintainability or turn around time on the availability of an individual gas turbine driven power generation system particularly for offshore structures in Malaysia. The equipment availability model is based on an individual equipment setting and data obtained from one of the offshore oil and gas production facilities off the east coast of Oeninsular Malaysia.
