Ten campaigns across five arrays, from November 2025 to August 2026. Blades rebuilt on the turbine, cable pulled inside the transition piece, bolts logged against the design table. Every date below includes the days the weather took.
Fictional wind farms and fictional crews. The work described is the work this trade actually does.
Sixty-two blades inspected from ropes, forty-one leading edges rebuilt on the turbine. No jack-up vessel was mobilised for any of them. Median turbine downtime per blade: 2.4 days, weather included.

Thirty-one array cable terminations inside the transition piece, including four re-pulls after seabed movement exposed the cable ahead of winter. Every pull logged against the design table.
Campaign lead — J. Halvorsen · Cable jointers ×6 · Survey lead — H. Berg · ROV pilot — T. Bakken · Vessel — CTV, 24 pax
Bolt tension verified on forty-four flange connections between monopile, transition piece and tower. Every value recorded against the design table. Nothing signed off from memory.

One hundred and twelve kilometres of array cable route surveyed before the winter storms. Three sections of exposed cable found, charted and handed to the operator inside the same mobilisation; two were re-covered by a rock placement vessel before the first gale.

Turbine returned to service in a nine-hour window between two depressions. Significant wave height 1.4 m at transfer, 2.6 m six hours later. The window was the whole job.

General visual inspection of all fifty-eight turbines: tower internals, transition piece, ladders, davits, bolted connections and blade root from the hub. Two hundred and forty findings raised, thirty-one of them ranked for action inside the same season. The array kept turning for the whole campaign; nothing on this scope needs a stop.

Scour protection surveyed on twenty-six monopiles after a winter of easterlies. Rock cover was found thinned on nine of them and the survey handed over as a charted work list, not as a report. We do not place rock. We tell the operator where it is missing and how much.
Survey lead — E. Mazur · ROV supervisor — D. Feddersen · ROV pilot — T. Bakken · Data processors ×3 · Vessel — workboat, shallow draft
Trailing edge bonds opened on nineteen blades, repaired from ropes and closed the same day where the cure allowed it. Eleven repairs are ones we mapped from the survey vessel the winter before, which is why the ropes went up knowing exactly where to stop.

Every one of the thirty-one terminations from the winter campaign re-entered and inspected: seals, hang-off, bend restrictors, earthing. Four J-tube seals replaced. The point of the visit was to check our own work with somebody else’s eyes on it.

Two array cables re-terminated after an insulation test failed on the second string. Both pulls done inside a single settled spell in August, because the alternative was to leave a string down until spring. Test values went to the operator before the crew came off the tower.

Sources. Significant wave heights, vessel types (CTV, SOV, walk-to-work, ROV) and the scope of work described are real industry practice — the CTV transfer limit of about 1.50 m significant wave height comes from the 2026 review of CTV transfer safety in Ocean Engineering and from ABPmer. Wind farm names, campaign dates, quantities, crew names and vessel counts are invented for this concept. KELDVIK is not a real company and none of these campaigns took place.
