International Inspection

What International Inspection does

International Inspection LLC is a U.S. nondestructive testing (NDT) and nondestructive examination (NDE) service provider founded in 1967 as Ronald Nisbet Associates and operating under its current name since 1997. The company delivers on-site inspection services across five offices on the U.S. West Coast (Seattle, Portland, Santa Fe Springs/Los Angeles, San Diego) and Gulf Coast (Houston), serving maritime, construction, fabrication, petrochemical, communications (cell tower), and geophysical end-markets. Core technical capabilities span ultrasonic testing (UT), industrial radiography (RT) using Iridium-192 isotopes with mobile darkrooms, magnetic particle (MT), liquid penetrant (PT), visual testing (VT), positive material identification (PMI) via handheld XRF, ground penetrating radar (GPR), and subsurface interface radar (SIR), plus rope access NDT via SPRAT-certified technicians.

The company earns revenue primarily through project-based professional services engagements billed per inspection, with pricing varying by scope, complexity, and geography. Named enterprise customers include Carnival Cruise Lines, Guam Shipyard, USS Missouri, Harley Marine, Greenberry Industrial, Disney California Adventure, Puget Sound Naval Shipyard, and Zidell Marine; the Seattle office alone runs approximately 3,000 x-ray welder qualification tests per year for the Navy and 1,000+ for private West Coast clients. Competitive positioning is built on seven classification society certifications (ABS, Lloyd's Register, DNV, NKK, RINA, Bureau Veritas, IRS), ASNT Corporate Partnership, ISNETWORLD membership, and a 50+ year operating record. Since September 2018, International Inspection has operated as a wholly owned subsidiary of Applied Technical Services (ATS), an Atlanta-based testing, inspection, and engineering consulting firm, using the partnership to expand Gulf Coast and East Coast marine services.

Direct peers

• Team Industrial Services: Specialty NDE and inspection services firm focused on refining, petrochemical, pipeline, and power, with substantial field-deployable NDT capability and a similarly enterprise-driven GTM. Directly comparable on technical method mix and customer profile.
• Mistras Group: Leading NDE/NDT service and product company offering similar inspection methods (ultrasonic, radiographic, eddy current, acoustic emission) with strong positions in oil & gas, aerospace, civil infrastructure, and power — a head-to-head competitor in many of International Inspection's verticals.
• Acuren: Large North American NDT and inspection services provider serving oil & gas, petrochemical, power, and pipeline markets with similar methods (UT, RT, MT, PT, VT) and an enterprise field-sales model closely aligned to International Inspection's core business.
• Applied Technical Services: Parent company of International Inspection since September 2018. ATS provides testing, inspection, and engineering consulting with 50+ years of experience and offers overlapping NDT capabilities (mechanical, chemical, electrical, NDT) across multiple industries, making it the most directly comparable peer.

Broad incumbents

• Bureau Veritas: Global Testing, Inspection & Certification (TIC) incumbent; International Inspection is one of its recognized external specialists for hull gauging. Overlaps heavily in marine classification society services but operates at much larger scale across many industries.
• SGS: World's largest TIC company with broad industrial inspection, marine surveying, and NDT service lines. Competes for the same shipowners and industrial customers but as one of many service lines in a global portfolio.
• Intertek: Global TIC incumbent providing asset integrity management, NDT, and marine services to oil & gas, power, and transportation. Comparable on classification society work and structural inspection, but as part of a much wider portfolio.
• TÜV SÜD: Global TIC player with industrial and marine inspection services, particularly in Europe and Asia. Overlaps with International Inspection on industrial NDE, weld inspection, and certification-related services.
• Terracon Consultants: US-based engineering consulting firm with a national geotechnical and materials testing footprint including NDT-related services for infrastructure. Comparable on the concrete/structural inspection side but with a much broader engineering focus.

Regional players

• ECS Group: European-rooted TIC group providing marine and industrial NDT/inspection services. Comparable technical service offering but primarily serves European and Asian shipyards rather than the US West/Gulf Coast focus of International Inspection.
