Wind turbine inspections

Challenge

To ensure the continuous optimal performance of offshore wind turbines, a well-defined service program is implemented, with skilled technicians conducting preventive maintenance. Wind farms situated far from land or a suitable service port are typically served by SOV vessels, large and efficient service vessels. While the crew on SOVs can perform full-service tasks on multiple turbines per day, they are constrained by the physical limitations of moving back and forth, up and down, carrying tools, and hoisting spare parts etc.

Solution

There is significant potential to enhance service efficiency by leveraging new technology. This innovation project focuses on fully autonomous wind turbine inspection and parcel deliveries, such as tool deliveries, using drones and fixed charging stations on offshore service vessels. This approach introduces an unprecedented level of autonomy and speed, optimizing the O&M costs associated with servicing offshore wind turbines.

The drone is designed to be "flexible", serving multiple purposes. It operates as a small offshore helicopter, capable of parcel delivery and offshore wind turbine inspection, and can also participate in rescue operations. In the long term, it aims to have several other functions.

The multi-purpose functionality of the drones allows for a reduction in navigation to offshore wind turbines, thereby decreasing both costs and CO2 emissions associated with the maintenance of wind farms.
