What Sentinel Integrity Solutions does

Sentinel Integrity Solutions, Inc. is a privately held, Houston-based non-destructive testing (NDT) and inspection services firm founded in 2006 that serves the U.S. petrochemical, refining, LNG, and pipeline industries. The company operates from five offices across the Gulf Coast (Houston, Port Allen/LA, Corpus Christi, Nederland) and the Pacific Northwest (Ferndale, WA), and has accumulated more than 12 million safe man-hours. Its service portfolio spans Turnaround Services, On-Stream/Nested Inspection, Asset Integrity Management Services (AIMS), Conventional NDT (UT, LPI, MPT, PMI, RT), Advanced NDT (AUT, PAUT, TOFD, MFL, ECA, RTR, HTHA, Pump Can Inspection), Storage Tank Inspection, Rope Access Inspection, Refractory Inspection and Testing, Tubing Inspection, and Radiography Services.

The company's technology stack is anchored by certified inspector expertise (API 510/570/653/936, AWS) and a small set of proprietary inspection methods, most notably an in-situ vertical pump can inspection technique that does not require equipment removal and a patent-pending pulsed eddy current (PEC) system for corrosion under insulation detection. Automated Ultrasonic Testing (AUT) platforms support high-speed data acquisition (up to 20 inches per second) with sub-thousandth-inch encoded scanning accuracy, and Sharck Probes deliver eddy current array inspection of carbon steel welds at up to 100 feet per hour. The AIMS division adds program-level capabilities including RBI assessments, PSM compliance auditing, and software-platform expertise (Meridium, PCMS, Shield, UltraPipe).

Sentinel generates revenue through project-based professional services contracts tied to specific inspection scopes during refinery and petrochemical turnarounds and on-stream operations. Go-to-market is direct enterprise field sales led by the CEO, President, and VP of Sales & Marketing, supported by regional Division/Operations Managers; marketing relies on industry reputation, technical content, safety thought leadership, and conference participation. Pricing is quote-based and not publicly disclosed, with scope, duration, and certification requirements driving contract value. Named enterprise customers include ExxonMobil (Baton Rouge Refinery), Shell (Polymers Pennsylvania Chemicals Project), Philadelphia Energy Solutions, and AlonUSA (Krotz Springs Refinery).

Core offering

Sentinel Integrity Solutions provides comprehensive inspection and non-destructive testing (NDT) services to petrochemical, refining, LNG, and energy industry clients. The company delivers turnaround inspections, on-stream/nested inspections, asset integrity management, conventional and advanced NDT, storage tank inspection, refractory inspection, rope access inspection, tubing inspection, and radiography services using API-certified inspectors and proprietary methods.

Product overview

Sentinel Integrity Solutions is a petrochemical inspection services company offering a comprehensive portfolio of non-destructive testing and inspection services organized around two main pillars: conventional NDT methods (UT, LPI, MPT, PMI, RT) and advanced NDT techniques (AUT, PAUT, TOFD, MFL, ECA, RTR, HTHA). The company's service ecosystem includes Turnaround Services with pre/post turnaround planning and digital reporting tools; Asset Integrity Management Services (AIMS) for mechanical integrity program optimization; Storage Tank Inspection with internal/external capabilities and drone technology; Rope Access Inspection; Refractory Inspection and Testing with mobile laboratory; and specialized Tubing Inspection using electromagnetic techniques. The company operates as a service-delivery model rather than a software platform, providing certified inspectors and technicians for on-stream, nested, and turnaround inspection activities across the Gulf Coast region.
