Orsted has introduced heavy-lift cargo drones (HLCD) for the first time in an operational campaign at the Borssele 1&2 Offshore Wind Farm, marking a notable advancement in operational efficiency and safety within the offshore wind sector.
The 70kg drones, which have a wingspan of 2.6 meters, are designed to transport up to 100kg of cargo from an offshore supply vessel directly to the top of each of the 94 turbines at the wind farm. This innovation follows previous trials and experience with drones in offshore wind farms, including a test at the Hornsea 1 Offshore Wind Farm in the UK.
The deployment of these drones replaces the traditional method of using a crane on a vessel to lift cargo onto the transition piece of each turbine. The conventional process, which involves moving the cargo from the vessel to the turbine and then using the nacelle's crane to place it on top, can take approximately six hours per unit. In contrast, the drone flight from the vessel to the turbine takes about four minutes, significantly accelerating the process.
By utilizing drones, Orsted has been able to complete tasks at Borssele 10-15 times faster than usual. This efficiency is achieved while reducing the need for multiple vessel trips between turbines and the shore, thereby decreasing operational costs and carbon emissions.
Rasmus Errboe, Orsted's chief commercial officer and deputy chief executive, highlighted the significance of this innovation. He noted that Orsted's commitment to integrating new technologies, like drones, exemplifies its leadership in advancing offshore wind technology. Errboe emphasized that the use of drones not only enhances safety and reduces costs but also contributes to improving the commercial viability of offshore wind energy for investors, governments, and corporations.
The implementation of drones at Borssele 1&2 is expected to enhance operational safety by minimizing the need for turbine shutdowns during cargo deliveries and reducing the overall risk associated with personnel operations. Orsted is also looking to expand its partnerships with top cargo drone operators and service providers to further develop the supply chain and explore additional applications of this technology.
