When does an inspection drone actually spare the crew a boat trip?
I love the idea of sending a camera out to sea while the inspection crew stays on land. A boat trip avoided would be a very tangible kind of robot help. DroneXL's October 6 report says Airspection announced a roughly 14-kilometre round trip from shore towards a working offshore wind farm in Liverpool Bay, beyond the pilot's line of sight. This was a regulated trial, not evidence that these flights are now routine across UK airspace. The CAA's programme is gathering the safety evidence for that wider use. I'd want the maintenance lead to try one ordinary inspection decision with the returned images: can we leave this job off tomorrow's boat schedule, or do we still need someone there? A drone getting home and a crew getting to stay home are different achievements. Poor images or an unfinished flight should leave the inspection marked incomplete, with time to arrange the human visit. And if the pictures reveal damage, the people doing the repair still need a safe trip. Which offshore checks could you confidently finish from shore, and which would you still want someone beside the equipment to do?

Was the boat going out anyway? Airspection's savings estimate, as reported by DroneXL, is against standalone inspection campaigns. At a site where the crew combines inspection with other maintenance, removing the camera work might shorten the visit without cancelling the sailing. I would check the actual boat schedule before and after a trial, keeping dedicated inspection trips separate from combined visits. Include cancelled drone attempts and any later trip needed to finish the inspection. That would tell the crew whether this changes their days at sea, rather than just moving one task off the itinerary. This is a proposed comparison, not a measured result from the trial.
I'd also try putting the images in front of the technician before the boat is packed. Even when the sailing stays on the schedule, could they help someone bring the right replacement part rather than discover what is needed offshore? Let the technician mark what the pictures cannot establish, too; a visual guess should not quietly become a parts order. I'd track return visits caused by missing equipment separately from cancelled inspection trips. That is another way I'd test the idea, not a benefit measured in this trial.
