Safety first: NDT protocols for offshore wind turbine testing

Offshore wind farms are often located in an environment with challenging conditions – wind, rain, sun, and seawater. 

How do you ensure the safety of NDT technicians when working in offshore wind farms? 

What can you do to guarantee their safety when conducting wind turbine testing? 

This blog looks at the protocols that NDT professionals can follow when conducting wind turbine testing, as well as the emerging technologies that are used to enhance safety. 

From unmanned aerial vehicles to artificial intelligence, these advancements are reshaping the landscape of wind turbine testing, steering the industry towards greater reliability and sustainability. 

Comprehensive training programmes

The first line of defence against potential risks in offshore wind farms is a well-trained workforce. 

At NDT Group, rigorous training programmes are designed to equip our workers with the knowledge and skills needed to navigate the specific challenges of offshore environments when conducting wind turbine testing. 

This includes instruction on emergency procedures, equipment operation, and awareness of environmental hazards. 

By ensuring that every team member is adequately trained, we lay the foundation for a safer working environment.

At NDT Group, our technicians hold IRATA rope access level qualifications, meaning we can offer our inspection services at height and in difficult-to-access areas. 

Every team member working in the sector is GWO-certified, ensuring that they are trained to reduce the risk associated with working in the wind turbine industry.

Personal protective equipment (PPE)

Specialised Personal Protective Equipment (PPE) designed to withstand harsh conditions can be worn when carrying out wind turbine inspections. 

Workers are equipped with waterproof and wind-resistant clothing, helmets, safety goggles, and non-slip boots. 

Harnesses and life jackets are mandatory, especially for tasks conducted at height or near the water’s edge. 

Regular inspections of PPE are conducted to identify any signs of wear or damage, ensuring the continuous protection of our workers.

Emerging technology

Undoubtedly, technology is one of the safest ways of carrying out wind turbine testing. 

The use of mobile NDT technologies is safer, faster and more cost-effective than using manual inspection methods in wind turbine inspections. 

Here are some of the NDT technologies that we use in the Renewable Energy sector: 

Unmanned aerial vehicles (UAVs)

Unmanned Aerial Vehicles, commonly known as drones, have become indispensable in the maintenance and inspection of offshore wind farms. 

Equipped with high-resolution cameras and sensors, UAVs offer a bird’s-eye view of wind turbine structures, enabling rapid and comprehensive visual inspections. 

Drones are particularly valuable for assessing hard-to-reach areas, reducing the need for manual inspections and enhancing overall safety.

Remotely operated vehicles (ROVs)

Under the sea, inspections pose unique challenges in offshore wind farms, and Remotely Operated Vehicles (ROVs) are the solution to these challenges. 

These remotely controlled underwater robots navigate the depths to inspect submerged components of wind turbines, such as foundations and cables. 

ROVs equipped with cameras and sensors provide real-time data, allowing for efficient and accurate assessments without exposing human divers to the risks of deep-sea operations.

Condition monitoring systems

Continuous monitoring of the condition of critical components is essential for maximising the lifespan and performance of offshore wind turbines. 

Condition monitoring systems use sensors and data analytics to assess the health of various components, detecting early signs of wear, fatigue, or potential failures. 

This proactive approach enables you to schedule maintenance activities strategically, minimising downtime and reducing overall operational costs.

Artificial intelligence (AI)

The integration of Artificial Intelligence has revolutionised the analysis of vast datasets generated by offshore wind farms. 

AI algorithms can identify patterns, predict potential faults, and optimise operational parameters. 

Machine learning models enhance the accuracy of predictive maintenance, allowing for timely interventions to prevent equipment failures. 

This data-driven approach not only increases reliability but also contributes to the overall efficiency of offshore wind energy production.

Augmented reality (AR) for remote diagnostic support

AR technology is making gains in remote diagnostic support for offshore wind farms. 

Maintenance personnel can wear AR-enabled devices, such as smart glasses, providing them with augmented information and guidance during inspections or repairs. 

Technicians located onshore can remotely visualise the situation, offer real-time support, and even overlay digital information onto physical components, streamlining decision-making and improving the accuracy of diagnostics.

Fully autonomous inspections

The future of offshore wind farm inspections is leaning towards full autonomy. 

Fully autonomous vehicles, both aerial and underwater, can conduct routine inspections and assessments without human intervention. 

These systems use advanced sensors, AI, and navigation technologies to navigate complex environments, ensuring thorough inspections while minimising operational costs and risks to human personnel.

Safety in wind turbine testing

The incorporation of cutting-edge technologies is reshaping the offshore wind energy landscape, bringing in an era of increased efficiency, safety, and sustainability. 

From aerial and underwater drones to AI-driven analytics and fully autonomous inspections, these advancements not only optimise operations but also contribute to the growth and reliability of offshore wind farms. 

As technology continues to evolve, the offshore wind industry is ready for further innovation, reaffirming its crucial role in the global transition to clean and sustainable energy sources.
