Thanks for your continued involvement and diligence on PBOP Hazops. I don’t know what the PBOP Project would do if we did not have you involved…  So, the project and I truly appreciate your personal effort – the project’s success and future safety are in large part due to your involvement.

Thanks again!

Dr. Summers,

I thoroughly enjoyed the SIL Verification class this past week.  Thank you for taking time out of your busy schedule to provide this instruction.  I found it extremely valuable.

Saulsbury-Feagan/Midmar Hazop


Worked with Kent Mitchell this week on a PHA for Feagan’s Midmar gas treating and processing facility.
The effort was well conducted, Kent is very knowledgeable and thorough and easy to work with.
I think we all remained friends during the week!

I would look forward to his stewarding another PHA/Hazop and would recommend him to other clients.

Midmar Gas PHA

Last week I had the pleasure to work with Kent Mitchell conducting the PHA on the new plant for Midmar Gas. He was very helpful and very professional in his job. He kept the team focused on the objectives and we completed the task ahead of schedule. It would be a pleasure to ask Kent back out to Odessa whenever needed for future business.

Thank you,

Tom Brown Plant Supervisor



“A great technical forum that provided new learning’s, an exchange of established practices and procedures and the introduction of new teammates. These opportunities can only help to drive forward good engineering practice for the management of safety instrumented systems”

Young Professionals

Hi Angela,

Just wanted to drop a line to thank you for presenting at the YP session last Friday. We have received very good feedback about your presentation. Good presentations like yours greatly contributed to the success of the conference which continues to be a popular resource to the Texas petrochemical industry.

Thank you again,

Brookhaven National Laboratory

Bill Hearn and SIS-TECH worked seamlessly with Brookhaven National Laboratory to provide a clear, concise safety integrity analysis of the proposed NSLS-II protection designs, including suggesting a modification that increased the design final effectiveness by more than 10X at low cost. He also suggested many modifications to the system that will improve the overall reliability that the system will achieve. Bill had the opportunity to present the results of the study to our management, they were satisfied with the results and left the meeting with a sense that the job was done accurately and was presented in a way that they could understand. I would use Bill for the next study that our facility requires.”

I really appreciate all the time and effort that went into getting this SIS project completed on time.

We had a tight schedule to start with, and then it was made even tighter … I am very happy that you and the others in your company that worked on this project were able to come through for us. I have heard many people at this plant site make the comment that this project has been a success beyond their expectations … I know the project was only a success due to the major efforts made by you and all the others involved. Your skills were a true asset to this project and you have been a great resource to call on when Triconex issues have arised during the project.

I too look forward to continue to work with you and everyone else at SIS-Tech.”
