A robotic, data-driven way to inspect critical plant assets — without putting people in harm’s way.

Just days

Full critical-asset assessment in days not weeks.

5 mm

Wall-thickness reading every 5 mm — dense, repeatable, audit-ready coverage.

24 probes

Measuring in parallel at 9 m/min scan speed — fast coverage, no compromises.

↓ 90%

Far less human exposure to confined spaces, work at height and hazardous zones.

The challenge

Industrial inspections are still done the old way.

Manual workflows, dependence on access and sparse data — three structural limits that make outages slow, expensive and risky.

01

Safety exposure

Inspectors enter confined spaces, work at height and operate in hazardous zones. Every entry adds permits, supervision, rescue planning — and a longer exposure window.

02

Access & scaffolding

Traditional methods burn shutdown time on access preparation before any data is collected. Scaffolding adds cost, planning complexity and dependency on external resources.

03

Sparse, spot-check data

Conventional inspections rely on spot checks rather than full coverage. Gaps between measurement points make repair prioritization and lifetime assessment harder.

Why it matters

The cost of looking the wrong way.

Wall thinning, corrosion and fatigue failures rarely show up at the few points a manual inspection happens to touch — they show up between them.

Unplanned downtime

Tube failures, leaks and forced outages cost days of production per incident.

Safety incidents

Confined-space incidents and hazardous-zone exposure remain serious operational risks.

Over- or under-scoped repairs

Without dense data, teams either over-replace good steel or miss thin spots until they leak.

Inspection uncertainty

Sparse data weakens lifetime assessment, RBI models and the next outage’s planning.

The solution — NURA

Robotic NDT, where people don’t have to go.

NURA is a modular, automated ultrasonic-testing platform engineered for high-precision inspection of boilers, vessels and hanging-tube banks — collecting dense, audit-ready wall-thickness data while keeping operators out of the hazardous zone.

Safer by design

Operators stay outside the hazardous zone. The robot climbs walls and follows tubing.

Faster & denser

Parallel probes scan with dense pitch — coverage that is impossible manually within an outage window.

Decision-ready

Output is delivered as 2D/3D heat maps and integrated reports — not raw waveforms.

NURA inspection operator and boiler wall

The NURA robot

One modular platform.
Many geometries.

Engineered for high-precision automated NDT, NURA reconfigures to match the asset — from boiler walls to free-hanging tubes — without losing data density.

01 Boiler walls

Horizontal and vertical orientation, full coverage of center-to-center distances including larger pitches.

02 Independent hanging tubes

Clamp-based mounting, follows tube bends and supports indexed measurement tracks per tube.

03 Vessels & flat surfaces

Large-CTC and flat surfaces — no custom scanning rigs, full data precision retained.

04 Surface compatibility

Ferromagnetic surfaces for wall inspections and non-ferromagnetic mode for independent tubing.

Inspection modes

Three asset types. One platform. Same data quality.

Mode 01

Boiler wall inspection

Parallel probes for fast, repeatable coverage on horizontal and vertical walls.
5 mm scan pitch — thickness captured every 5 mm for high-density mapping.
Bent tube sections do not affect data — geometry is compensated.
Real-time analysis drives same-shift maintenance decisions.

Mode 02

Large CTC & flat surfaces

Flexible configurations — adaptable across different geometries.
Efficient scanning of larger gaps without losing precision.
No custom rigs required for wide-pitch boiler banks or flat vessel walls.
Lower inspection cost through reuse of one standard platform.

Mode 03

Independent hanging tubes

Clamp-based holding securely positions NURA on single or multiple tubes.
Dynamic tube adaptation follows bends without data distortion.
3 circumferential tracks per tube for fuller wall assessment.
Single-pass coverage across multiple parallel hanging tubes.

Approach — bank inspection

Superheater / evaporator / economizer.

A structured scan plan per row and per side — selectable measurement angles cover the high-risk circumferential positions on every accessible tube.
