Why PSI
Bigger capability.
Single-source accountability.
PSI is not just another contractor. We combine engineering expertise, ASME and NBIC code authority, field execution, fabrication, portable machining, and rotating equipment service under one organization — so the work moves and the accountability never gets handed off.
Safety
EMR 0.77 in 2026. Stop-work authority for every craftsperson on site.
Engineering
ASME and NBIC code expertise integrated with field execution.
Single Source
Eight specialty service lines under one accountable organization.
Speed
24/7 emergency mobilization nationwide.
Precision
Controlled shop fabrication with hold-point inspection on every job.
Accountability
One project manager. One safety standard. Documented turnover.
Trusted where the standards are highest.
When SpaceX prepared a Starship booster at Starbase, our tooling and trailers were on site. It is a reminder that the same teams, standards, and tooling that serve the Gulf Coast's largest refineries and chemical plants are trusted by the organizations pushing the hardest frontier in American industry.
