Non-Destructive Testing (NDT)

Radiographic inspection support for evaluating internal weld and material conditions in difficult-access industrial locations.

Radiographic Testing (RT)

Electromagnetic inspection for detecting and sizing surface-breaking cracks in conductive materials and welds.

ACFM Inspection

Difficult-access coating and corrosion inspection support for industrial structures, piping, tanks, and vessels.

NACE / Coating Inspections

Targeted thickness measurement and condition profiling for elevated and difficult-to-reach piping systems.

Pipe & Line Profiling

Hands-on access to difficult bridge components for visual inspection, documentation, NDT, and condition assessment.

Hull Inspections

Controlled access for inspection and condition assessment inside tanks, vessels, shafts, and restricted environments.

Confined Space Inspections

Ultrasonic inspection for material thickness, corrosion monitoring, and internal discontinuities in difficult-access assets.

Ultrasonic Testing (UT)

Advanced ultrasonic inspection providing detailed imaging of welds and materials in difficult-access locations.

Phased Array Ultrasonic Testing (PAUT)

Rope access support for API-based inspection programs involving piping, vessels, tanks, and industrial assets.

API Inspections

Quality assurance and quality control access support for construction, fabrication, maintenance, and industrial projects.

QA/QC Inspection Support

Inspection, NDT support, cleaning, coating repair, and localized maintenance for tanks and process vessels.

Vessel Inspection & Maintenance

Rope access inspection support for hulls and marine structures in shipyards, ports, and dry docks.
