Permian Basin Gas Plants

An Operator with 22 Gas Plants in the Permian Basin required to bring all pressure vessels into API 510 compliance

The plants ranged in age from new to 30+ years. Many had been through multiple owners and a lot of the original construction data for older plants was missing.

There were 4412 total pressure vessels, 90% were overdue for inspection

The objective was to bring all vessels into API 510 compliance while minimizing the duration of plant outages

The results

Houston Integrity Consultants supplied a team of experienced engineers and technical specialists to perform a Qualitative RBI assessment. The assessment was then modified based on any historical results.
