“…Drones are currently used in a wide range of applications, including fisheries monitoring, maritime patrol, coastline monitoring, drug traffic monitoring, high-accuracy terrain mapping, crop and harvest monitoring, road traffic monitoring and control, law enforcement, forest fire detection, high voltage power line monitoring, etc. (for further see [5]). Santos et al [6] described how the maintenance of power lines could be performed with the help of drones.…”

With increasing global investment in offshore wind energy and rapid deployment of wind power technologies in deep water hazardous environments, the in-service inspection of wind turbines and their related infrastructure plays an important role in the safe and efficient operation of wind farm fleets. The use of unmanned aerial vehicle (UAV) and remotely piloted aircraft (RPA)—commonly known as “drones”—for remote inspection of wind energy infrastructure has received a great deal of attention in recent years. Drones have significant potential to reduce not only the number of times that personnel will need to travel to and climb up the wind turbines, but also the amount of heavy lifting equipment required to carry out the dangerous inspection works. Drones can also shorten the duration of downtime needed to detect defects and collect diagnostic information from the entire wind farm. Despite all these potential benefits, the drone-based inspection technology in the offshore wind industry is still at an early stage of development and its reliability has yet to be proven. Any unforeseen failure of the drone system during its mission may cause an interruption in inspection operations, and thereby, significant reduction in the electricity generated by wind turbines. In this paper, we propose a semiquantitative reliability analysis framework to identify and evaluate the criticality of mission failures—at both system and component levels—in inspection drones, with the goal of lowering the operation and maintenance (O&M) costs as well as improving personnel safety in offshore wind farms. Our framework is built based upon two well-established failure analysis methodologies, namely, fault tree analysis (FTA) and failure mode and effects analysis (FMEA). It is then tested and verified on a drone prototype, which was developed in the laboratory for taking aerial photography and video of both onshore and offshore wind turbines. The most significant failure modes and underlying root causes within the drone system are identified, and the effects of the failures on the system’s operation are analysed. Finally, some innovative solutions are proposed on how to minimize the risks associated with mission failures in inspection drones.

“…Remote operations have already been realised in a wide variety of areas, such as distributed or centralised control systems used in manufacturing, remote offshore drilling, driverless mining equipment, loading cranes, telesurgery [2] and remotely piloted aircraft systems (RPAScommonly referred to as drones) [3]. A number of aspects seem characteristic of remote operations, especially:…”

Greater connectivity is transforming critical infrastructures profoundly. One specific aspect enabled by connectivity are remote operations, which allow for the provision of services difficult to provide in a direct capacity, physically (e.g., due to cost or resource availability). Domains of applications are very diverse, e.g.: industry, public services, healthcare, culture. In the domain of Air Traffic Management (ATM), increased connectivity is seen as one of the main drivers of the improvement of operations and building of capacity to handle the expected traffic increase. The concept of Remote Tower operations provides the capacity to manage tower operations remotely from a virtual tower and remote centre. It increasingly appears as a valuable alternative to traditional control towers. However, one can wonder about the risks introduced by the necessary reliance on network infrastructures and remote sensors. What happens to remote operations when these are not fully, if at all, functional? How dangerously dependent on the digital infrastructure are the capabilities introduced by remote operations? Such questions take particular significance in the face of the cyber threat: cyber-attacks on digital assets and services can impair the capacity to perform ATM safely from remote. Resilience then represents the capacity to handle two interrelated, but different, disruptions: of ATM operations; and of digital services. In the first case, the primary emergency, the system needs to adapt to mitigate the impact on operations (e.g., switch to other modes of operations or divert traffic) and return to sound operations. In the second case, challenges are associated with the system's capacity to identify, understand and address the cyber event. Re-establishing impaired digital services in a timely manner is critical because the adapted ATM operations are not sustainable. Inspired by crisis management, the paper explores challenges and strategies for resilient performance in the face of disruptions to the digital infrastructure.
