Offshore wind is a key component of the net zero strategies around the world, with an ambitious target of achieving 50 GW installed capacity by 2030 and potentially more than 100 GW by 2050 in the UK alone.
Against this backdrop of burgeoning demand, new and scalable technologies such as Lilypad will prove essential for the growth of offshore wind farm assets.
Lilypad has been designed to provide safe and efficient inspection services for offshore wind farm assets using resident autonomous UAVs, optimising operations and maintenance with reliable data whilst enabling sustainable industry growth.
With operational, economic and environmental benefits, Lilypad is set to revolutionise the way operators monitor and maintain offshore assets to maximise wind farm performance.
Powering the offshore wind industry with cutting edge robotics and data.
Working collaboratively with customers, an offshore survey will be completed to determine the size of the operation and the optimum layout of the offshore infrastructure. Specialist contractors will then install and commission all equipment to be ready for service.
All customer inspection requirements and schedules are loaded into a Lilypad customer interface portal. This is a web-based application where long-term inspection schedules can be loaded and ad-hoc requests can be submitted. Inspection status can be monitored with progress reports made available to customers via the portal.
Schedules and requests that have been loaded onto the Lilypad customer interface portal will be received by the ground control station and used to generate Lilypad mission plans. The dedicated operations team will create the mission plans based on external factors such as weather, other air users and further wind farm activities.
A secure, persistent and weatherproof SATCOM link provides continuous communication between onshore and offshore Lilypad assets, with BVLOS data links enabling command and control of the Lilypad inspection UAV and enclosure.
The permanently deployed Lilypad inspection UAV is then launched and flown by the remote pilot to the required turbine to complete the automated inspection task. The Lilypad inspection UAV can cover a range of approximately 15km with an average flight time of 45 minutes. The Lilypad inspection UAV will utilise GNSS, LiDAR and AI to fly an optimised route for inspection completion. Safety, reliability and availability is ensured through rugged back-up systems and is recognised through CAA authorisation.
Throughout the tasking, the Lilypad inspection UAV will hop between the installed Lilypad enclosures where a battery swapping mechanism enables rapid recharging. During this quick turnaround time the Lilypad inspection UAV will also offload inspection data as well as completing pre- and post-flight checks before taking off again.
Upon completion of the inspection task, the Lilypad UAV will dock in the final enclosure. Data is then downloaded and securely transferred back to the ground control station via the secure SATCOM link.
Inspection image data is processed using a state-of-the-art, industrially proven, data analytics tool which combines blade inspection experts and AI-enabled damage recognition software. Bespoke customer inspection reports are then created.
All customer inspection reports are uploaded onto the customer interface portal (and also provided in PDF format) for the customer to access, analyse and plan next steps.
The exact duration depends on the size of the turbine. As an example, the target for a 7MW turbine, with 75 metre blades, is to complete a turbine inspection (including all four aspects of all three blades) within 15 minutes.
Offshore hardware is tailored to each wind farm based on a number of factors:
As a rough guide, the UAV will usually be able to fly up to 10km to a turbine from its enclosure, complete a turbine inspection and return to an enclosure. During customer setup, the Lilypad operations team will determine how many inspection UAVs and enclosures are required to achieve the optimal and most cost-efficient inspection mapping of wind farm assets.
The system as configured out of the box can be used to undertake ad-hoc surveillance tasks, perimeter surveillance and general at-range inspections.
The inspection UAV utilises a modular construction, giving it the ability to carry alternative sensor payloads. This could range from hyperspectral imaging of structures to sub-sea bathymetry and beyond. The AI navigational software can be modified to perform additional functions such as automated recognition of other objects and features, and to perform alternative automated inspection routines supplementary to blade related activity.
