Explore the fundamentals of an overview of gas turbine and maintenance tasks relating to the drivers, strategy, structure and different maintenance approaches. Maintenance cycle, maintenance schedule and equipment reliability will be examined. Different maintenance activities commonly undertaken on a gas turbine package at different time intervals and takes a closer look at condition maintenance. Finally, simulations of a real-life gas turbine maintenance task of calibrating a pressure transmitter is provided to guide students through the entire process for undertaking this activity.
