Monopiles, jackets and transition pieces
Commissioning software for wind farms where the same scope repeats a hundred times over open water.
A fixed-bottom offshore wind farm is one record set executed across every monopile, transition piece, tower, nacelle and blade set in the array. Deskely defines that record set once, instantiates it per asset, and reports readiness by turbine, string and array.

The problem
Repetition is not the hard part — consolidating the repetition is.
Every turbine in the array needs the same foundation, tower, nacelle, blade and electrical evidence. On paper that is a hundred identical packs travelling out on vessels and coming back scanned, incomplete, and impossible to compare.
The weekly question is always the same: how many turbines are actually ready, and what is holding the rest? Answering it means opening a folder per asset, because nothing rolls up on its own.
Deskely instantiates the record set per asset from one template, so the fleet view is a by-product of the signatures rather than a Monday morning reconstruction.
Setting up the register
Model the array the way it is actually energised — by string, not by spreadsheet row.
Turbines belong to strings, strings land on the offshore substation, and each turbine carries its foundation, tower section, nacelle, blades and its own low voltage and auxiliary systems. Deskely holds all of that as one register with each asset mapped to the string it energises through.
Single line diagrams, cable schedules and equipment lists can be parsed into the draft register instead of typed, with the source document held behind every tag.
Because the register mirrors the electrical topology, readiness can be reported for one turbine, one string or the whole array without maintaining three trackers.
Execution at sea
The transfer window decides everything, so the tablet has to work with no signal.
Technicians are inside a nacelle for a few hours with no connectivity and a vessel waiting. A missing signature discovered onshore is not an afternoon of admin — it is another transfer.
Records, drawings and punch capture all work offline. Mandatory fields are enforced before the record can be closed, so the technician learns about the gap while still standing at the asset.
Everything syncs on return to the vessel or shore, keeping the time and place the signature was actually taken.
Energisation and takeover
Turbines are handed over one at a time, so the evidence has to close one at a time.
Energisation is gated on the electrical evidence beneath it: cable termination and testing, protection settings, earthing, and no open Category A punch. Takeover then sits above that with the mechanical and commissioning record set complete.
Deskely enforces both gates from the records, so a turbine that is genuinely ready can be certified the same day rather than waiting for a batch review.
The takeover pack for each asset exports on demand — signed records, punch position and certificates — which is what the owner's engineer and the warranty provider will both ask for.
Serial defects across a fleet
A hundred identical turbines share identical faults, so the value of the record set is in what it tells you across the fleet.
When the same nacelle model is commissioned eighty times, a defect found on position A14 is rarely unique to A14. A yaw brake torque out of tolerance, a blade root bolt tensioned against the wrong procedure revision or a batch of pitch accumulators from one supplier week will show up again and again down the array.
With a pack per turbine in a folder per turbine, nobody sees the pattern until the OEM's service team meets it in year two. By then the campaign vessel has demobilised and the fix costs a jack-up rather than a technician on a walk-to-work gangway.
Because every position runs the same templated record set in Deskely, punch and test results are comparable across the fleet from day one: filter one failed check across all positions, see it is nineteen turbines rather than one, and turn it into a campaign while the crews are still offshore.
The turbine dossier
One record set, instantiated a hundred times, and comparable across every position in the array.
A fixed-bottom turbine's takeover pack is only as good as the individual records beneath it. Deskely holds each one against the asset it was taken on, so a position can be certified the moment its evidence closes rather than when a batch review gets around to it.
Tower and nacelle bolt torque and tensioning records
Every flange and structural connection was tightened to the specified torque or tension sequence and value.
During tower stacking and nacelle mating, before the blades are lifted.
Transition piece grout inspection report
The grouted connection between monopile and transition piece has cured within tolerance and shows no voiding.
Following the grout cure period, before the tower is stacked.
Array cable pull-in and termination record
The inter-array cable was pulled into the turbine J-tube without exceeding bend radius or tension limits and terminated to the cable schedule.
During balance-of-plant cable installation, ahead of energisation.
HV switchgear withstand and cable TDR baseline
Insulation integrity of the cable and switchgear meets the specified withstand level, with a time-domain reflectometry trace recorded as the reference for future fault-finding.
Before the string is permitted to energise.
SCADA point-to-point verification
Every signal from the turbine controller reaches the operator's control system correctly mapped and with the right polarity.
During commissioning, before remote control is handed to the operations team.
Turbine taking-over certificate with punch carried at takeover
The full mechanical, electrical and commissioning record set is signed, and any residual Category B punch is listed with an owner.
At the point the asset transfers from the installation contractor to the owner.
How it runs
From one turbine template to a fully certified array.
Fixed-bottom scopes reward structure set up early. The array is known long before the first monopile goes in, so the register and the record set can be finished before mobilisation.
- 01
Build the asset hierarchy
Array, strings, turbines and their foundation, tower, nacelle, blade and electrical subsystems, mapped to the substation they energise through.
- 02
Template the record set once
Define the foundation, tower, nacelle, blade, LV and HV checksheets for the turbine type, then instantiate across every asset.
- 03
Load the port scope
Pre-assembly and marshalling checks recorded at the port so the asset arrives offshore with its history already attached.
- 04
Run the campaign offline
Technicians complete records and raise punch on tablet inside the nacelle, syncing on return to the vessel.
- 05
Gate energisation per string
Cable termination, protection and earthing evidence must be signed before the string is permitted to energise.
- 06
Certify and hand over per turbine
Takeover certificates issue per asset from the signed records, with the pack exportable the same day.
