A wide range of maintenance and inspection services for onshore and offshore wind turbines.
Tru-Tec NDT’s Advanced technicians enable the inspection and maintenance of wind turbines throughout various stages of the project lifecycle. Tru-Tec NDT offers a complete range of maintenance and inspection services for both onshore and offshore wind turbines.
The maintenance and inspection of turbines are critical to meet insurance policies and statutory requirements.
Tru-Tec NDT’s maintenance technicians effectively inspect and maintain turbines. This prolongs the lifespan, productivity and the return on investment of turbines.
Tru-Tec NDT provides:
Volumetric inspections are implemented to ensure products are acceptable and are compliant to the required acceptance criteria using:
Manual Ultrasonic Testing (UT) – applied for the inspection of weldments, corrosion mapping, thickness examination and lamination inspections.
Time of Flight Diffraction (TOFD) – TOFD transmits ultrasonic waves which are diffracted, and reflected sound waves separated by time. The difference in time is used to locate and size discontinuities. TOFD is used in the examination of piping and pressure vessels because of its advantage s over pulse echo which include, speed, objectivity, repeatability, insensitivity to weld surface condition and discontinuity orientation. Assessment of results can be interpreted in real time or recorded for post examination review. This technique can utilise automatic scanning system with an encoder to confirm 100 % coverage and eliminate human error.
Phased Array Ultrasonic Testing (PAUT) – PAUT uses phased array beams which can be steered, scanned, swept and focused electronically, unlike conventional single probe ultrasonic testing. The technique can be used for the inspection of welds, Wrought products and castings. Assessment of results can be interpreted in real-time or recorded for post-examination review. This technique can utilise automatic scanning system with an encoder to confirm 100 % coverage and eliminate human error.
Radiography Testing (RT) – Applied to the examination of weldments.
Computer Radiography Testing (CRT) – Applied to the examination of weldments.
Vibration and Acoustic Emission Analysis (AE) – to detect turbine failures at their earliest stages.
Surface inspections are implemented to ensure products are acceptable and are compliant to the required acceptance criteria using:
Magnetic Particle Testing (MT) – Applied to Ferrous material, MT can be carried out using colour contrast and fluorescent techniques using portable yokes.
Liquid Penetrant Testing (PT) – Applied to non-ferrous material, PT can be carried out using colour contrast and fluorescent techniques.
Visual Testing (VT) – Applied to all material ensuring the surface condition is suitable for examination and ensuring visible defects are not present. Tru-Tec NDT also remotely visually examines internal bores and weldments using borescopes, which can record examinations.
Eddy Current Testing (ET) – Applied to coated surfaces, ET can effectively and efficiently detect surface breaking discontinuities without the need for coating removal and re-application.
Alternating Current Field Measurement (ACFM) – Applied to coated surfaces, ACFM can effectively and efficiently detect surface breaking discontinuities without the need for coating removal and re-application. ACFM can systematically measure the length and depth of surface-breaking discontinuities, which are recorded and reported for repeatable examination and remote witnessing/inspection of test results.
Drone Inspection – To employ remote visual inspection with thermographic imaging for surface breaking discontinuities. Tru-Tec NDT’s qualified personnel work in accordance with health and safety regulations, Civil Aviation Authority (CCA) & Permission for Commercial Operations (PfCO).
Hardness Testing – Tru-Tec NDT provides hardness testing in accordance with Rockwell, Brinell and Vickers.
