Semi-submersible, spar and TLP platforms
Completions software for floating wind, where the turbine is commissioned before it ever reaches the field.
Floating wind moves the assembly work back to the quayside and adds a hull, a mooring spread and a dynamic cable to the completions scope. Deskely keeps the quayside evidence attached to the unit through tow-out, hook-up and energisation.

The problem
Three organisations touch the unit before it floats away, and each keeps its own file.
The hull is built and outfitted in one yard, the turbine is integrated at the quayside by the supplier, and the marine contractor takes the unit out and connects it to a pre-installed mooring spread. Each holds a different part of the evidence.
When the unit is on station and something does not behave, the question is what was tested at the quay and what was left for offshore. On paper, that answer is spread across a yard QA system, a supplier's own tool and a marine construction report.
Deskely holds all of it against the unit, so tow-out is a handover of a complete file rather than the start of an archive search.
One unit, one register
The hull, the turbine and the station-keeping system belong to the same asset.
Deskely models the floating unit as the platform it is: hull compartments and ballast, marine systems, tower and nacelle, plus the mooring lines, anchors and dynamic cable that arrive later.
Every party works in the same register, scoped by access rights to its own package, so the yard cannot see the supplier's rates and the supplier cannot edit the yard's records — while the completions lead sees one number.
Records signed at the quay stay with the unit through tow, hook-up and energisation. Nothing is re-entered because the location changed.
Tow-out and preservation
Between integration and hook-up the unit sits, and everything on it has to stay warranty-clean.
There can be weeks or months between quayside completion and connection to the grid. Rotating equipment, switchgear, hydraulics and the nacelle itself need preservation routines running the whole time.
Routines are defined per tag at their own cadence and run independently of the commissioning sequence, so an overdue cycle surfaces immediately rather than during a warranty dispute after first power.
The completed cycles become the record that settles who is responsible if a component fails in the first operating year.
Hook-up and first power
Moorings, dynamic cable and turbine each earn their own certificate.
Station-keeping is proven by mooring line pre-tension and as-installed records. The dynamic cable is proven by continuity, insulation resistance and termination testing. The turbine is proven by its own commissioning set.
Deskely gates first power on the ones that must be closed first, and carries the rest as visible, owned items rather than an informal list.
The result is a unit that can be accepted individually, which matters when the farm energises unit by unit rather than all at once.
Mooring and dynamic cable integrity
A floating unit is only as good as what holds it, and the mooring and dynamic cable records are the evidence that it will stay there.
Each unit arrives on station with mooring lines to hook up and pretension, connectors to lock and verify, a dynamic cable to pull in through the bend stiffener, buoyancy modules positioned along the lazy wave, and monitoring instrumentation that has to read true before the unit is accepted.
That scope is executed by a marine spread, witnessed by class and the owner's marine warranty surveyor, and captured in a completely different record culture to the turbine above it — usually a set of vessel reports rather than tagged, signed test records.
Deskely holds mooring lines, connectors, the dynamic cable and its ancillaries as tagged assets with their own test records, so line tension, connector make-up and cable integrity sit in the same register as the nacelle, and station-keeping acceptance is a gate on the same board as first power.
The unit dossier
Evidence taken at the quay has to travel with the unit through tow-out and hook-up, not get left at the yard.
A floating unit collects its record set across three organisations before it ever reaches station. Deskely keeps every one of those records against the unit, so the file that leaves the quay is the same file that supports takeover offshore.
Nacelle and tower bolt tensioning record
Structural connections were made up to the specified tension during quayside integration, before tow-out.
During turbine integration at the quay.
Hull ballast and compartment inspection report
Ballast tanks and watertight compartments hold the as-designed condition ahead of tow-out.
Prior to sail-away from the integration quay.
Mooring line pre-tension record
Each mooring line was tensioned to its design value and the pattern matches the as-installed drawing.
During hook-up to the pre-laid mooring spread on station.
Dynamic cable termination and TDR baseline
The dynamic cable was terminated correctly at both ends and a reflectometry trace is captured as the reference before power flows.
After pull-in through the bend stiffener, before energisation.
SCADA point-to-point verification
Turbine and mooring monitoring signals reach the operator's system correctly, including load and tension instrumentation added for station-keeping.
During commissioning on station, before remote handover.
Unit taking-over certificate with punch carried at takeover
Hull, mooring, dynamic cable and turbine records are all signed, with any open Category B items listed against an owner.
At acceptance of the individual floating unit.
How it runs
From quayside integration to a unit on station.
Floating scopes are won or lost at the quay. The more evidence that is complete and provable before tow-out, the shorter and cheaper the offshore campaign.
- 01

- 03
Capture quayside integration
Integration and pre-commissioning records signed at the quay, with photos, against the unit itself.
- 04
Run preservation through the tow
Per-tag routines continue on their own cadence from integration to hook-up.
- 05
Record mooring and cable evidence
Pre-tension, as-installed positions, dynamic cable continuity and termination testing held under the unit.
