Rope Access Structural Inspection, NDT and Coating Survey

Rope access solves an access problem and not an inspection problem. For a structure that would otherwise need scaffolding, a crane-mounted platform or a shutdown, rope access gets a technician onto the surface within hours and not weeks. The structural inspection that follows is the same one, to the same standard, by the same qualified people. itmad provides rope access structural inspection, NDT and coating survey, with IRATA-certified teams working alongside ISO 9712 qualified inspection personnel. itmad operates across the Middle East, Asia and Europe. Last reviewed: October 2026.

How the service is delivered

The access itself is done by IRATA-certified teams working to recognised industry practice, with the supervision ratios, rescue provision and equipment inspection that the discipline requires. Technicians at IRATA Level I, II and III are assigned according to how complex and risky the access is. itmad supplies the inspection side: it decides what has to be examined and against which criteria, performs or directs the examination, and writes the report against the governing code or specification.

That combination matters. A rope access technician who is not a qualified inspector produces photographs, while a qualified inspector who cannot reach the surface produces nothing, so the work is only useful where both are present on the same scope.

What is delivered by rope access

Non-destructive testing at height covers ultrasonic thickness measurement, magnetic particle inspection, dye penetrant and visual examination, carried out by technicians qualified to ISO 9712 or ASNT SNT-TC-1A Level II in the method applied. Structural inspection examines steelwork, connections, welds, corrosion and coating breakdown close up, at the elevations where deterioration concentrates: splash zones, stress concentration points, crevices and areas where water tracks. A coating survey assesses condition, measures dry film thickness to SSPC-PA 2, tests adhesion and detects holidays, and maps how far the breakdown extends so that remedial work and paint specification can be planned.

Where it applies

Flare stacks, chimneys and vent structures; storage tank shells, roofs and internals; process structures, pipe racks and elevated pipework; offshore platforms, jackets, splash zones and underdeck; jetties, quay structures and berthing dolphins; bridges, towers and masts; building facades, atria and high-level structures; and confined and restricted access voids.

Standards and qualifications

NDT carried out by rope access is governed by the same standards as ground-level work, so ASME, AWS, ISO and client specifications apply without modification. Technicians hold ISO 9712 or ASNT SNT-TC-1A Level II qualifications in the methods they apply, and the rope access teams are certified to IRATA standards, which govern technician qualification levels, supervision ratios, rescue provision and equipment inspection.

When rope access is the right answer

Choose it when access is the main cost, when the structure cannot carry or accommodate scaffolding, when other trades must keep working below, or when the job is short compared with the time that conventional access would take to erect and strike. Typical mobilisation is one to two days, against two to four weeks for scaffolding on a flare stack or tank shell.

Avoid it when the surface is large and continuous, when long periods of close work are needed everywhere, or when wind, nearby hazards or operational limits make suspension unsafe. Scaffolding or powered access is better in those cases, and itmad will say so and will not sell the harder method.

What the client receives

An inspection report that identifies the structure and the areas examined, the method applied and the standard or specification followed, and the findings with location, dimension and photographic evidence. Thickness readings or coating measurements are included where they were the scope, together with an assessment against the acceptance criteria in the specification. Areas that could not be reached are stated and not omitted, and the report gives technician qualification and equipment calibration traceability.

Scheduling

Rope access inspection is used at industrial facilities, refineries, tank farms, ports and offshore installations. Work is planned around how the plant operates, including shutdowns, where the access window is fixed.

Frequently asked questions

What is rope access inspection and when is it used?

It uses IRATA-certified rope access teams to position qualified inspectors on structures such as flare stacks, tank shells, bridges, offshore platforms, jetties and facades, where scaffolding or powered access would be impractical, slow or costly. The inspection is the same examination, to the same standard, as ground-level work.

What NDT methods can be carried out by rope access?

Ultrasonic thickness measurement, magnetic particle, dye penetrant and visual examination, all by technicians qualified to ISO 9712 or ASNT SNT-TC-1A Level II in the method used. Coating surveys can be done by rope access too, covering dry film thickness, adhesion and holiday detection.

What certifications do the rope access teams hold?

The rope access teams are certified to IRATA standards, which govern technician levels, supervision ratios, rescue provision and equipment inspection. The inspection personnel hold ISO 9712 or ASNT Level II qualifications in the methods applied.

When is rope access the wrong choice?

For large, continuous surface areas where prolonged close work is needed at every point, or where suspension is unsafe because of wind, proximity hazards or operational constraints. Where scaffolding or powered access is better, itmad says so.

How much faster is rope access than scaffolding?

Typical mobilisation is one to two days, against two to four weeks for scaffolding on a flare stack or tank shell. It puts a technician on the surface in hours and not weeks.

What does a rope access inspection report include?

The structure and areas examined, the method and standard applied, findings with location, dimension and photographs, thickness or coating measurements where in scope, assessment against acceptance criteria, and technician and equipment traceability. Any areas that could not be reached are stated and not omitted.
