This paper discusses the technical issues and business con siderations involved in the application of advanced technology to gas turbine replacement parts. Today's gas turbine owners are fac ing increased demands on their older machines in the areas of in creased fuel efficiency, increased power output, and reduced oper ating costs. These demands can only be met through the use of superior replacement parts, which is made possible through the ap plication of state-of-the-art technology. This

... hnology is being made available for most turbine, combustion, and controls replace ment parts. sometimes frustrating because it requires upgrading only part of a machine, given the restraints of existing design on the other parts. Consequently, getting the combination of enthusiastic and high-quality design efforts on a project can be difficult. 3. Adequacy of Market Research -Understanding what the marketplace wants is one of the most important issues. This is costly; it requires extensive market research to ensure that
