"In our attempt to be proactive with our 35 gas turbines, APS frequently performs borescope inspections utilizing the borescope services from ATS and the OEM’s. I felt it was necessary to let you know after reviewing many borescope inspection reports, some with significant issues identified, that ATS’ borescope inspection services appear to be far superior to the OEM’s. A few of the reasons ATS’ borescope inspection services are superior are as follows.

  • Borescope inspections are very thorough and the pictures are clear and high quality
  • Inspectors always reference any prior issues identified in the borescope inspection reports and re-inspect these issues
  • Multiple high quality pictures are taken of any indications at different angles such that a proper evaluation can be performed
  • Measurements of indications are shown directly on the borescope pictures (not just a measurement range in the notes) and appear to be very accurate
  • Turbine preparation documentation is provided to maximize efficiency and help prevent schedule delays
  • A Borescope Preparation Procedure is provided with clear direction and pictures which is extremely helpful to plant personnel
  • ATS maintains a thorough knowledge of fleet issues and understands specific issues on various turbines
  • ATS’ blending services reach beyond the capabilities of the OEM’s
  • During forced outages, ATS typically responds within 24 hours
  • Pricing for borescope inspections is typically lower than the OEM’s
  • Preliminary borescope reports are provided promptly such that there is opportunity to prepare and plan to promptly address any issues

Your company has certainly helped us reach some of our goals for availability and reliability, and has made my job a little easier. Please let your inspectors know as well how pleased we are with ATS’ services."

Thanks again for your help.

"I just wanted to take a moment to say thank you to everyone at ATS for supporting our Fall outage inspection needs. I appreciate all of your efforts in supporting our schedule and being flexible with some minor changes we had to make. As usual, all members of the inspection team were professional and courteous and were pleasure to work with. Michael, I appreciate you sending the reports in a timely manner. Thanks again and I will be in touch in the near future.

Great job by your engineers !!! Not only they showed extreme proficiency but also professionalism and sensitivity to our customer needs. Rick & Steven came up with suggestions to minimize BSI duration in order to provide the customer with quicker preliminary findings thus allowing MPSA and the customer more reaction time in the event that corrections are needed. The customer was equally impressed !!

This is the third time that ATS participates in one of my projects and I am glad to know that your services are not limited to BSI inspections, we will certainly talk in the near future about your other offerings. In the meantime please make my comments extensive to Rick & Steve and thanks for the good work.

Best regards,

Thanks for the report and the inspection. This will give us something for engineering to review and determine repairs. Robert was very easy to work with, self supportive, and did a high quality inspection that we always get with ATS.





Thanks you very much for the prompt report. I also appreciate the flexibility in being able to schedule the repairs and professionalism of your personnel who were on site.

There is no questions we will continue to work with ATS in the future for our inspection and repair needs.
