Offshore wind turbines: operation & maintenance optimization

Bullet Complete optimization for offshore wind turbines

Operation & maintenance (O&M) costs are the main cost driver in offshore energy due to environmental conditions and the difficulty of accessing the wind turbines. Sensing & monitoring systems could help operators reach the expected decline in cost to 70 /MWh by 2030. The highest criticality (in €/kWh) in offshore wind energy is caused by structural failure, which mainly occurs due to corrosion processes that are neither adequately predicted nor monitored. For that reason, it is crucial to implement new monitoring systems into the offshore wind farms to help wind farm operators take predictive smart O&M decisions by fully considering structural components' real and future status.

Bullet Ad hoc solutions

  • Integral solutions that will allow wind farm operators to carry out accurate predictive maintenance in the future with the aim of reducing O&M costs and increasing the yearly electric energy output from the offshore renewable resources.

  • Monitoring systems that are capable of remotely detecting phenomena such as the corrosion level at exact points of the tower (splash-zone) and the tower–platform junction or the tightening force of the bolts in the wind turbine blades, as a remote predictive maintenance reduces maintenance costs considerably without increasing the likelihood of operation failures.

Bullet Knowledge and expertise

  • Robust wireless communications to operate in harsh environments.

  • Customized embedded systems: accurate, real-time, small, low-cost, low power consumption and low weight.

  • Ultrasound-embedded processing for unattended real-time monitoring of corrosion, tightening force, etc.

  • Positioning algorithms for precise indoor real-time operation required by unmanned aerial vehicle solutions, etc.

  • Power management techniques, such as energy harvesting and ultra low power modes, for power consumption optimization.
