Berlin, Germany (SPX) Nov 10, 2023
In a groundbreaking initiative that could significantly streamline operations in offshore wind farms, the German Aerospace Center (DLR) has successfully piloted an unmanned helicopter to autonomously navigate and communicate with wind turbines. This test, a collaboration with the energy supplier Energie Baden-Wuerttemberg AG (EnBW), is a part of the ‘Upcoming Drones Windfarm’ (UDW) project and sets the stage for the upcoming ‘Offshore Drone Challenge’ in June 2024.
The logistical challenges of maintaining offshore wind turbines are substantial; maintenance teams and materials traditionally face long journeys to reach these installations. Drones, with their agility and speed, present a promising solution to these challenges. “For automated use in a wind farm, the drone must therefore exchange information with the turbines,” explained Sebastian Cain from DLR’s Institute of Flight Systems, emphasizing the need for a seamless ‘conversation’ between the drones and the wind turbines to find the optimum path for operations.
In a recent test at the EnBW wind farm in Schwienau, Lower Saxony, the DLR’s small unmanned helicopter, superARTIS, demonstrated this capability. It accounted for various factors such as the operating status of the turbines, weather conditions, and wake turbulence in its flight path. The drone successfully announced its arrival at the turbines and received clearance for a safe approach, showcasing a potential future where such technology could be deployed offshore to enhance the efficiency and safety of wind farm operations.
The implications of this research are far-reaching, with seven commercial drone manufacturers set to build on these findings. These companies will showcase their technologies at the National Experimental Test Center for Unmanned Aircraft Systems in Cochstedt during the ‘Offshore Drone Challenge.’ Anavia, Flowcopter, Flying Basket, HyFly, NEXaero, Unmanned Helicopters, and Volocopter are among the selected participants, which hints at a competitive and innovative environment.
“We will see several firsts in terms of the number and size of the aircraft,” Cain said, highlighting the scale of the upcoming demonstrations. Michael Splett, Head of Offshore Operations at EnBW and a member of the National Drone Council, underscored the importance of integrating drone technology with wind energy for a sustainable energy supply.
The ‘Offshore Drone Challenge’ will be a comprehensive testing ground for relevant flight maneuvers, software, and design modifications required to connect drones and wind farm systems effectively. The focus on conducting these tests on land, rather than at sea, speaks to the emphasis on safety, simplicity, and cost-effectiveness before the technology is applied offshore.
The DLR Institute of Air Transport in Hamburg, along with the National Experimental Test Center for Unmanned Aircraft Systems, plays a vital role in the UDW project, which is supported by the Federal Ministry for Economic Affairs and Climate Action.
In conclusion, the advancements in drone technology showcased by the DLR and EnBW are set to make significant strides in the maintenance and operation of offshore wind farms. While the project’s immediate goal is to facilitate the transport of materials, the vision extends to the transportation of personnel, marking a new horizon in renewable energy operations.
