Renewable Energy NDT Solutions

Overview

Where we work. Drone visual and zoom surveys of blades, lightning receptors and tower exteriors, with UT on welds and flanges. GPR and ultrasonic scanning of bases, grout and anchorage zones, where foundation problems usually begin. Radiometric thermal flights that locate hot spots, failed strings and diode faults across the whole array. ROV inspection of dam faces, intakes, penstocks and tailraces at operating level. No drawdown. Live thermal surveys of connections, switchgear and transformers, finding hot joints before they trip. Thickness and corrosion mapping on boilers, ducting and structures in hard, hot environments.

What we survey

Foundations: the part nobody sees. Turbine foundations crack quietly. Water gets into the grout and anchorage zone, the embedded can works loose by fractions of a millimetre, and the first visible symptom is expensive. Scanning the base with GPR and ultrasonics finds voiding, cracking and reinforcement issues while they are still a monitoring item rather than a layup. Pair it with our concrete and structural integrity service for strength and cover data on the same visit.

Thermography that pays for itself. On solar, a single thermal flight positions every underperforming panel for the O&M team and turns a vague yield shortfall into a work order. On grid assets, the same camera finds the resistive joint at a safe distance while everything stays live. Flights are flown under our CAA operational authorisation; the platform detail is on our drone surveying service page.

Scan before you repair. That is the standing advice for every Renewable Energy client, and the reason NDTScan reports what the concrete contains before anyone specifies what to do about it.

Services Available Nationwide

GPR Concrete Scanning Pre-drill and pre-coring surveys, rebar and mesh mapping, post-tensioned tendon detection, void detection, slab thickness and cover estimation and RAAC identification.
Ultrasonic Testing of Concrete Ultrasonic pulse velocity, pulse echo and SONREB for uniformity, thickness, delamination and compressive strength estimation where GPR alone cannot answer the question.
Concrete Compressive Strength Assessment Rebound hammer, UPV combined method and managed core extraction to BS EN 13791, with independent reporting for engineering acceptance and building control.

About NDTScan

NDTScan is a specialist non-destructive testing company based in Oxford and led by Neil Smuts. Its core disciplines are GPR concrete scanning, ultrasonic testing and in-situ compressive strength assessment, brought together in its concrete scanning and structural condition survey service. NDTScan is a Level 4 UKCSS Operator, the first in the UK to achieve that certification. Renewable Energy and the whole of the United Kingdom are within the company's everyday working area, and all work is reported to a standard suitable for engineering acceptance. RAAC identification is covered on the RAAC surveys page, and steel on the ultrasonic thickness and corrosion mapping page.

Renewable Energy NDT FAQs

Frequently Asked Questions.

Common questions about renewable energy ndt solutions from NDTScan, answered by the team that does the work.

Can you inspect wind turbines without taking them offline for long?

Drone surveys of blades and towers need only a short pause per turbine rather than a rope-access campaign, and tower welds, bolted flanges and foundations are inspected with the turbine generating wherever the method allows.

What do you check on wind turbine foundations?

GPR and ultrasonic methods scan the reinforced concrete base for cracking, voiding and reinforcement layout, and check the grout and anchorage zone around the embedded can or anchor cage, which is where foundation problems usually start.

How does solar farm thermography work?

A drone with a radiometric thermal camera flies the array and finds hot spots, failed strings, faulty diodes and soiling patterns across thousands of panels in a single flight, with each anomaly positioned for the O&M team.

Can you inspect hydro assets underwater?

Yes. ROVs with imaging sonar and HD video inspect dam faces, intakes, penstocks and tailraces at operating level, so the survey does not cost generation.

Do you work on operational substations?

Thermal imaging surveys of connections, switchgear and transformers are done from a safe distance on live equipment, finding the hot joints before they become outages.
