The start-up engineering and operational background of the TDS engineers and technicians provides the basis for the TDS In-Service Inspection (ISI) Programs. TDS provides competent and knowledgeable engineers specializing in turbine generator equipment. Our specialized, in depth knowledge of the design parameters and normal operating conditions of turbine generators,  is applied to our ISI Program to recognize nonconforming conditions with the machine in service. 


The TDS In-Service Inspections (ISI) are conducted at normal high load steady state operation to evaluate the condition of the turbine generator and its subsystems.A thermodynamic performance analysis is conducted with long term tracking of the operational parameters. ISI Programs are intended to improve unit operating reliability through the identification of impending problems and they offer useful recommendations for immediate and planned maintenance activities. Correction of impending problems before they become a forced outage, improves the reliability and availability of the unit and enhances your bottom line dollars.

Steady State vibration data is collected on the turbine generator bearing vibration probes or temporary probes (if necessary) and a vibration analysis is conducted. Vibration, three phase motor currents, and operating conditions will be monitored on all the subsystem motors, pumps and blowers and the data trended for degrading conditions. All of the automatic pump start tests will be initiated to verify the proper start sequence of backup pumps. All valve tests and normal on-line testing will be conducted to verify proper action of the tests. Gas turbine ISI Programs are available and performance models have been developed by our gas turbine start-up engineers.
