01
The challenge
Scour protection around monopiles has to be checked after every big storm season. Survey vessels struggle inside an operating array, and the owner wanted every foundation checked before the insurance renewal.
02
How we flew it
Two K6 worked from one crew-transfer vessel. Each vehicle flew a spiral around a monopile, mapped the rock armour at 5 cm and moved to the next turbine on its own.
Tidewire graded every foundation against the design scour depth.
03
What we found
All 60 foundations were surveyed in six days with no turbine shutdowns. Four needed remedial rock placement; the rest were cleared for another year.

Flagged for repair
The turbines never stopped. That alone paid for the campaign.

Line 7 needed a full integrity survey before winter. One K6 flew it end to end and found the free span a ship survey had missed.
