Due to the specialized nature of the components it consults on, TTI has integrated a variety of technical disciplines in order to provide the types of solutions commonly sought by the power plant industry.

Quick profile

• Independent consulting firm located in Rochester, NY
• Ongoing steam and gas turbine research efforts being performed by the Electric Power Research Institute (EPRI)
• Specialized in power generation equipment engineering and related research
• Technically equipped to solve aero-thermal, aero-fluid dynamics and mechanical problems.
• Provides third party solutions to plant operators, insurance carriers, part suppliers and equipment manufacturers by conducting comprehensive research studies.
• Deals with both reliability and performance issues both on the turbine deck and by mean of advanced computer simulations.

Typical applications

• Root failure cause investigation
• Risk analysis
• Insurance claim adjustment
• Repair/replacement strategies
• Remaining life assessment
• Design optimization
• Performance upgrade strategies

General approach to problems

• Familiarity with common turbine problems used to first access options, and then to define additional technical scope.
• Field experience used to access balancing and alignment related problems
• Computer simulations used to aero fluid dynamics, operating stress and temperature etc
• Stress and temperature next related to sources of damage (LCF, HCF, TMF, CAF, SCC and Creep)
• Operating history is taken in conjunction with material properties and component condition to recreate the accumulation of damage.
• Results are present in explicit detail to establish a consensus on conclusions and to support our recommendations.
