Abstract
The maintenance history of GE Frame 7 gas turbines has been reviewed. Twelve users of this equipment were surveyed. The survey addressed the physical configuration of hardware and accessories necessary to achieve minimum downtime following a forced or scheduled shutdown. Guidelines identifying areas of concern were established to improve the maintainability of gas turbines in power generation service. These criteria were reviewed with the General Electric Company's 7001F gas turbine design team during September 1984 for applicability to this new model. Several major tasks were reviewed by The Dow Chemical Company's (DOW) maintenance technicians to indicate an industrial's approach to maintenance. Goals are provided for certain tasks complete with an example of a typical hot gas path inspection, and a typical major inspection. The examples are broken down in some detail with a Critical Path Map (CPM) included in the appendix. The availability of DOW's three Frame 7 E's since installation is shown with their complete list of outages. 7 tabs.
