Offshore logistics drones

The EnBW research project on drone technology in the offshore wind sector

Download image

Offshore wind energy is playing a key role in helping us to achieve our climate goals. Wind farms at sea have a twenty-year service life. They are often situated far from the coast. We have always developed smart solutions to ensure the efficient operation and maintenance of these wind farms, whether in the form of modern maintenance concepts or service ships. We have realized that we can conduct our business activities even more flexibly and directly with future technologies such as drones, while at the same time significantly cutting carbon emissions. That is why we launched an offshore logistics drones research project. This project „Upcoming Drones Windfarm“ is funded by the Federal Ministry for Economic Affairs and Climate Action.

The research project

Drone technology will play an even larger role worldwide, particularly in the area of logistics. Many sectors see real potential for the transportation of people and materials. The EnBW research project will examine whether the use of drones is promising for the offshore wind sector and especially establish which requirements will need to be met.

Logistical challenges associated with ever larger offshore wind farms are expected to be met by automated transport drones in the future to reduce operating costs.

Our approach

Business models are being drawn up within the research project and the efficiency of drones examined.

From a technological perspective, the transport drones should be able to carry loads in the form of tools, maintenance consumables and spare parts, but later also personnel, to and from their work locations in the wind farm. For such uses, the project is evaluating suitable configurations and load-bearing systems for the drone and shaping the interaction between offshore wind farm and drone.

Interfaces must be created at both hardware and software level to enable the use of transport drones. Legal framework conditions must also be taken into consideration in these concepts. How will drones and wind farms be certified for this purpose in the future? Which international conditions must be taken into account for such OWP in the future? The automation concept is developed and validated in a simulated environment set up as part of the project. At the same time, operational aspects relevant to the implementation of the transport mission are worked on. The aim here is to achieve a high degree of efficiency and maximum operational safety.

Communication between wind farm system and unmanned helicopter successfully demonstrated at Schwienau onshore wind farm

The unmanned DLR superARTIS helicopter approaches the wind turbine

In October 2023, the unmanned DLR superARTIS small helicopter took off from the EnBW Schwienau II and III wind farms in Lower Saxony/Germany.

The aim was to test the communication between the drone and the wind farm, which had previously been worked out in theory and programmed at DLR and EnBW. The communication interface created enabled the superARTIS to receive data such as wind speed, wind direction, wind turbine orientation and rotor speed and then select its flight route.

During the test, the superARTS first made sure that the rotor of the wind turbine to be approached was stationary. The helicopter then safely approached the wind turbine from the side facing away from the wind until a predetermined distance was reached. If the drone had not received clearance for this, it would have automatically flown into a holding pattern.

The test did not take place at sea, but on land to make the experiments safer and easier to carry out. For a realistic scenario, the researchers attached a payload to the drone. The results can be transferred to offshore installations. The communication between superARTIS and the wind turbine was designed for offshore operation and is being analysed in simulations.

What advantage do drones have over today’s logistics services with special ships and helicopters?

Download image

Ships used today generally not only have to be a means of transport, but also a hotel and material store at the same time. The reason for this is the long distance between the work location and the coast. Transfer by ship takes several hours, which is why daily transfer by ship to the wind farm is generally not economical. Engineers are accommodated and fed on the ship during their shift. Accordingly, personnel are also constantly needed to keep the ship running. The ship must also have the right equipment to enable the workers to cross over to the turbines in the wind farm even in heavy seas. This high degree of specialization makes the ships that are used very expensive. Nevertheless, ships currently remain the cheapest alternative in terms of logistics.

Helicopters are already available for transporting material and tools. They can be used very flexibly. Engineers and material can be dropped off directly at the work location – on the nacelle of a wind turbine, for instance. Transfer by helicopter to the wind farm takes a fraction of the time of transfer by ship due to the high speed of travel. The biggest drawback of helicopters is the cost. High fuel consumption and maintenance work are significant cost drivers.

Drones offer advantages in terms of cost and flexibility compared to the logistics options currently used. The high speed of travel means transfers are as fast as those involving helicopters. By switching to transport drones, it would also be possible to service offshore wind farms located a long distance from the coast without the need for accommodation in the wind farm. The anticipated operating costs of drones are lower than those of helicopters because drones are less complex. This has a significant impact on the amount of maintenance work needed for the drones. It is likely that drones will become more and more automated in the future, thereby cutting operating costs. The transport of materials in particular offers considerable potential for automation.

When will the drones be ready for service and when can they be used in offshore wind farms?

Download image

Many drone manufacturers have set themselves the goal of starting commercial operation of their drones within the next few years. The offshore wind farms must first be upgraded before drones can be used. Since the necessary framework conditions will only be determined in the course of the research project, it is difficult to estimate the timescale. Once the framework conditions have been established, they must be incorporated into the development of a new offshore wind farm. Such developments generally take several years.

Why is the research project being carried out when there are already manufacturers developing heavy-duty drones and air taxis?

Download image

It is not sufficient for drones merely to be available for use as transport drones in offshore wind farms. The relevant offshore wind farm must have the right equipment to enable the use of transport drones. Furthermore, the developed drones may require modifications to make them suitable for such use. It is therefore also necessary to familiarize manufacturers with the circumstances of the use case involving offshore wind energy.

What could be an obstacle to the use of drones in the offshore sector? Where do the difficulties lie?

Download image

The drone must have a high load-bearing capacity and long range for transport operations between the offshore wind farm and the coast. There are concepts from different manufacturers that promise to meet these criteria. The kind of drone required is not yet available.

Are drone flights safe?

Download image

The European Union Aviation Security Agency mandates high safety standards for drone flights that carry passengers. Drones used for transporting people must undergo certification similar to that used for aircraft.

Almost all of the currently available drone models are equipped with redundant power systems. In the event of a failure in the drone's power system during the flight, the remaining power systems can compensate for the failure. With many drone models, the flight to the planned destination can even be continued in such cases.

How are drones controlled? Is there a pilot?

Download image

The drones used for transporting passengers are controlled by on-board pilots. It is conceivable that drones used for transporting materials may be controlled by a remote pilot rather than an on-board pilot.

Who will operate the drones? Will EnBW become an aviation company?

Download image

The aim is to purchase drone flights as a service. The drones will be optimally utilized by also being used for other purposes. Idle time can thus be kept to a minimum, which in turn has a positive impact on operating costs.

Does the use of drones make economic sense?

Download image

Preliminary considerations on economic efficiency were discussed in the run-up to the research project. There is considerable potential for transport drones to be used economically in offshore wind farms. However, the use of transport drones does not make sense in every scenario.

Is the use of drones in offshore wind farms sustainable?

Download image

Most currently available drone models are electrically powered. In terms of sustainability, this offers advantages over the currently used logistics options. If the drones run on renewable power, emissions can be reduced when operating the offshore wind farms.
