Parts

GE Power Systems maintains a large volume of replacement parts to cover the requirements of gas tur-
bine owners. The parts protection system is designed for rapid response; however, there are periods of
heavy demand where certain parts may not be readily available for planned inspections.
It is strongly recommended that high probability parts be available on site prior to the start of inspections.
Spare and Renewal Parts sales personnel have responsibility for customer contact, to advise scheduling
of maintenance parts and identify additional parts needs. Local Spare and Renewal Parts sales personnel
can present operations spare parts recommendations and factor individual needs into gas turbine mainte-
nance philosophy as well as to provide for planned maintenance parts, including time tables and making
suitable recommendations concerning design improvements and modifications to improve reliability,
maintainability or reduce operating cost. In addition gas turbine parts programs such as interchangeabil-
ity, exchange plan, warehousing program, and repair and return policy can be identified.
