RELIABILITY AND MAINTENANCE OF GAS TURBINES FOR MARINE APPLICATIONS

This thesis proposes to analyze the reliability and availability of current gas turbine power plants available for marine usage. Actual service data was obtained and the calculations gave an indication of the expected failures of components within the gas turbine. From the data, it was found that to achieve a reasonable level of system reliability, the two worst subsystems causing breakdowns were the control and fuel supply subsystems. Improvement in reliability of the subsystems is advocated, possibly by replicating in the double or treble parallel redundancy mode. Three types of ship are considered for which the gas turbine could be applicable and the overall system reliability is carried out to determine the net effect of altering the reliabilities of individual components and recommendations are made with a view to improving the overall system. It is also proposed to define current maintenance practices applicable to gas turbines in industry and to apply these practices to the betterment of maintenance and repair carried out on board ship. A discussion of gas turbine maintenance and repair costs follows, in which an attempt is made to pinpoint certain important maintenance costs.
