GE Gas Turbine manual Maintenance Philosophy, Some KEY Points

GE5-2 Gas Turbine

MAINTENANCE PHILOSOPHY

A fundamental philosophy of the new GE5 gas turbine is simplicity of design, layout and procedures. This affords the GE5 a position of market leadership in cost and availability through innovative programs for service and sparing, and through package assembly and disassembly flexibility. Drawing on GE’s undisputed leadership in the design and manufacture of both aero-derivative and heavy-duty machines, the GE5 represents a unique marriage of the best of both types of engines.

This provides customers with the benefit of a variety of cost-effective service programs (e.g., condition-based maintenance, site-based or exchange engine programs) and the ability to tailor the service offering to best suite the customer’s specific applications.

SOME KEY POINTS:

Annual borescope inspections are the basis of the condition based maintenance program.

The inspection of the hot parts is carried out approximately every two years. Major overhaul of the gas turbine is required at around 50,000 fired hours, and can be completed on site, or in a shop; effects of downtime can be minimized through the use of an exchange engine.
