A gas turbine / turbo generator preventive maintenance schedule lists the checks and jobs done on the equipment at fixed intervals, how long each takes, and in what order of frequency, so problems are found before the gas turbine / turbo generator fails. This page gives the schedule used in the PlantOps360 task library for gas turbine / turbo generator, which follows common industry practice for general-purpose equipment. It is also searched for as gas turbine, GT, turbine generator, power turbine.
The maker’s manual and your site safety procedures always come first where they differ. Intervals set by law differ by state.
