What we are allowed to do, and what we do it with

Access is not a claim. It is a certificate with a date on it, a berth with a vessel in it, and a coordinator on shift at four in the morning. Everything on this page is either a ticket that expires or a hull that has to be paid for.

Services

Seven things, and the reason each one exists

Blade repair by rope access

Leading and trailing edge rebuilds, laminate repair, lightning receptor work, done on the turbine from ropes. No crane, no jack-up, no barge day rate. Cure time is the constraint, not the height.

Cable termination and array cable work

Pulls and terminations inside the transition piece, hang-off, bend restrictors, earthing, J-tube seals, re-terminations after a failed test. Every pull logged against the design table.

Torque and tension

Bolt tension verified and recorded on flange connections between monopile, transition piece and tower, plus blade root flanges. Values are recorded, not remembered. A signature without a number behind it is worth nothing.

General visual inspection

Planned walk-through of tower internals, platforms, ladders, davits, coatings and bolted connections. Findings are ranked, not just listed, so the operator knows what has to move this season and what can wait.

Subsea survey

Inspection-class ROV on cable route, scour protection and foundation. We find it, chart it and hand it over inside the same mobilisation. We do not place rock and we do not bury cable.

Marine coordination

Vessel movements, transfer decisions, permits to work and personnel-on-board tracking, run from one room, 24/7. The person who says stop is the same person all season.

Emergency call-out

An unplanned stop assessed inside the day and a crew on the water at the first workable tide. Contracted response, not a favour.

Fleet

Four kinds of hull, four different weather limits

Bases

Three quays, chosen for transit time and nothing else

Łeba · Poland · O&M base

Three CTV berths, workshop, blade repair store and the marine coordination centre. Closest base to the Baltic arrays and the reason the head office sits in Gdańsk.

Esbjerg · Denmark · warehouse

2 400 m² of covered store, consumables, rope access equipment and spares staged for North Sea campaigns. Mobilisation point for anything heavy.

Grimsby · United Kingdom · O&M base

Two CTV berths and the technician pool for the English east coast. Crews live within an hour of the quay, which is the whole point of a UK base.

Łeba is the first Polish O&M base built for offshore wind, Esbjerg is the world’s largest offshore wind base port, and Grimsby is the largest O&M cluster in the UK. Those three facts are real; KELDVIK’s presence in them is not.

Coordination

One room decides whether anybody goes to sea

One room in Łeba holds the vessel plan, the forecast and the permits to work. It runs 24/7, 365, and it is the only place where a transfer is approved. Forecasting is in-house on a three-hourly cycle, because a twelve-hourly forecast decides yesterday’s weather.

Talk to coordination

Sources. GWO Basic Safety Training is five modules valid for two years and Basic Technical Training is three modules (GWO standards; MITAGS). IRATA rope access runs Levels 1–3 with revalidation every three years (heightec; Dangle Academy). ISO 45001 was published in March 2018. Łeba, Esbjerg and Grimsby are real offshore wind service ports. The certificate counts, vessel counts, berth counts, floor area and system dates on this page are invented for the concept.
