SMC Team,

On behalf of MP, I would like to thank you for the successful design and fabrication of (2) meter skids to be used at our facilities in OK and IL. It has been my pleasure to establish a working relationship with your company, and I hope other project leaders are able to experience the same on future projects. The team-oriented atmosphere is evident, and I certainly appreciate your willingness to work with our inspectors and coordinate weekly with the project team. As with any first-time project, we encountered several hurdles but I believe SMC and MP have both learned from the events to mutually benefit future work.

I’d like to thank the following personnel specifically for their assistance in making this project a success:

Structural Welding – DM, KD, SC, DA and BB laid many beads on these large structures. All welds passed visual inspection and random mag. Thank you for your dedication to this project.

Pipe Welding – BB and TC combined for only (1) repair on over 100 butt and fillet welds for skids. Speaking from experience, welding of pipe components at MP gathers intense scrutiny and documentation. I appreciate your willingness to work with inspection to coordinate these efforts, and having welded myself, I have respect for the talent needed to do your jobs.

Saw Work – Thank you JS for adhering to all approved drawings and changes while cutting pieces for this job. Your efforts allowed the “puzzle pieces” to fit together correctly, which makes everyone around you more efficient. Thanks for your efforts.

Hydrotesting – MP and JW assisted by following our guidelines for pressure testing. This is another area that gathers intense scrutiny at MP and requires significant documentation. Thank you for working with inspection to verify the correct documentation was gathered and the test was run successfully.

Painting – MH, HS, and DD helped to put together perhaps the most easily scrutinized component of any MP skid; the white paint coating. I appreciate your efforts to apply the paint to company specifications, and your attention to details such as thorough bolt painting and touch-ups to vendor-purchased materials damaged in shipment.

Project Management – CW and SS played a critical role in the interface between MP and SMC. I specifically appreciate your transparency and proactive mindset toward making this project a success. Speaking from personal experience, this is a welcome exception to the standard skid fabricator interaction. My comments in Paragraph 1 above are a direct reflection of the quality of your work.
