Renewable energy

The offshore wind industry plays a critical role in driving the transition to clean, renewable energy. However, the challenges of building and maintaining wind farms in marine environments are considerable. These include complex seabed mapping, ensuring precision in construction, and conducting regular maintenance in harsh conditions.

From pre-lay surveys and environmental studies to operations and preventive maintenance, each phase of a wind farm’s lifecycle requires advanced, reliable technologies that can adapt to the ever-changing conditions at sea. To meet these demands, innovative, sustainable solutions are being adopted, reducing time, costs, and environmental impact while improving operational efficiency.

Exail’s expertise across every phase of wind farm development

Exail’s solutions are designed to support every stage of offshore wind farm development: 

  • initial environmental studies
  •  UXO (Unexploded Ordnance) surveys
  • site investigations
  • operations
  • predictive maintenance

    Our innovative and sustainable technologies, proven in very shallow waters and trusted worldwide, enhance operational efficiency by reducing the need for extensive equipment at sea. By leveraging uncrewed, reliable systems, we help minimize costs, improve safety, and streamline processes across your renewable energy projects.
