Advanced Technology turbine components have been developed for the GE MS5002 line of gas turbines that permit operation at a higher firing temperature. Those components include directionally solidified (DS) GTD-111 alloy stage-one buckets — the first GE application of a DS alloy in heavy-duty gas turbines. The Advanced Technology uprate improves turbine performance and extends turbine inspection intervals.

This paper provides an overview of the field modification of 21 mechanical drive units in Indonesia. The user’s technical objectives and uprate requirements are discussed along with installation experience and operating results to date. Advanced Technology component design features are illustrated and discussed in some detail with reference to their application in field units.
