Our Renewable Energy-Focused Services
Non-Destructive Testing (NDT) for Renewable Assets
OADR delivers certified, precise NDT to identify defects, corrosion, fatigue, and material issues in critical components without causing damage or downtime. Key applications include:- Ultrasonic Testing (UT) & Phased Array UT – blade spar cap delamination, tower weld inspections, foundation bolt integrity, and thickness gauging on monopiles/tubular structures
- Magnetic Particle Testing (MT) & Liquid Penetrant Testing (PT) – surface crack detection on tower flanges, nacelle components, and bolted connections
- Radiographic Testing (RT) – internal weld flaws in critical structures
- Visual & advanced inspections – blade leading-edge erosion, lightning protection systems, and composite material assessment
These techniques detect early-stage damage from environmental loads, lightning strikes, or manufacturing issues, extending asset life, reducing O&M costs, and preventing costly failures in wind turbines and solar infrastructure.
Industrial Rope Access for Renewable Energy Environments
Our IRATA-certified Rope access teams provide safe, efficient, low-impact access to elevated or confined areas — minimising the need for heavy cranes, scaffolding, or full shutdowns. Typical renewable applications include:
- Wind turbine blade inspections, repairs, leading-edge protection, and lightning receptor checks
- Tower internal/external inspections, painting, bolt torquing, and flange maintenance
- Nacelle, hub, and yaw system access for close-up NDT or repairs
- Solar tracker mechanisms, mounting structures, and elevated inverter/transformer inspection
- CSP mirror/heliostat cleaning, alignment checks, and structural assessments
Rope access enables rapid, targeted work at height, enhances technician safety in remote wind or solar sites, and supports minimal disruption to energy generation.

Drone Mapping, Surveying & Aerial Inspections for Renewables
Leveraging SACAA-approved advanced UAV technology, OADR provides fast, safe, high-accuracy data capture for large-scale renewable sites. Our services include:
- Wind farm blade & tower inspections (visual, thermal, and close-up imaging for cracks, erosion, lightning damage)
- Solar farm panel inspections (thermal hotspot detection, soiling assessment, string-level fault identification, and PV array mapping)
- Site topographic & Ortho mosaic mapping for project planning, layout optimisation, and progress tracking
- Volumetric analysis (e.g., earthworks, stockpiles) and environmental/rehabilitation monitoring
- 3D modelling of turbines, solar arrays, and infrastructure for digital twin creation and change detection
- Thermal imaging for electrical faults, overheating components, or performance inefficiencies
Drones reduce personnel risk in high-wind or elevated areas, cut inspection times dramatically (e.g., full wind farm scans in days vs. weeks), deliver centimetre-level precision, and enable frequent, cost-effective monitoring to support predictive maintenance and higher energy yield.
