IN Brief:
- Inch Cape will use 72 Vestas V236-15MW turbines across the almost 1.1GW Scottish offshore wind project.
- Dundee will handle 576 major turbine components through a 170,000m² marshalling and assembly yard.
- Cadeler’s Wind Mover will carry completed turbines offshore in batches of four from November.
Inch Cape Offshore Limited has moved its almost 1.1GW Scottish offshore wind project into turbine assembly, with components for 72 Vestas V236-15MW machines arriving at Forth Ports’ Port of Dundee. The first tower sections reached the port in early August, starting a logistics programme that will continue through late September before offshore installation begins in November. Inch Cape will be the first UK project to deploy the V236-15MW turbine.
The Dundee operation will handle 576 major turbine components: 288 tower sections, 216 blades, and 72 nacelles. Each turbine uses a four-section tower, three blades measuring 115.5 metres, and a nacelle containing the generator and associated electrical equipment. More than 130 people will work across a 170,000m² marshalling and assembly yard as deliveries, storage, assembly, commissioning, and load-out activities overlap.
That makes Dundee considerably more than a temporary storage base. Components arriving from separate manufacturing locations have to be inspected, protected, and positioned so they can be retrieved in installation sequence without blocking later deliveries. Tower sections, nacelles, blades, heavy-lift equipment, commissioning teams, and vessel schedules all have to converge at the right time, while the yard retains enough space to absorb incoming material and prepare complete turbine sets for offshore transfer.
The delivery sequence reflects those constraints. Tower sections are arriving first, followed by nacelles and then blades, with six vessels involved in bringing the components to Dundee. The tallest completed towers will reach 127.4 metres before load-out. Moving hardware of that scale through a busy port requires carefully planned lifting zones, laydown areas, transport routes, and weather limits, because a delay in one part of the sequence can quickly affect the next vessel call.
Cadeler’s new-build Wind Mover will install the turbines offshore, carrying them to the project area in batches of four. Each turnaround therefore concentrates a substantial amount of project value into a short port window: four sets of towers, nacelles, and blades must be ready, associated tooling must be available, and commissioning work has to be complete before the vessel leaves the berth. Discovering a missing component or unfinished task after an installation vessel arrives is one of the more expensive ways to lose schedule.
The turbine campaign is progressing alongside other major construction packages. At the Port of Cromarty Firth in Invergordon, Seaway7 is preparing Alfa Lift to install 54 pin piles using a purpose-designed installation frame before placing the project’s 18 jacket foundations. Marine and vessel-support work at Invergordon has already created a separate logistics operation around that heavy-lift programme, while offshore export-cable and inter-array cable work is also advancing.
Those parallel activities underline the number of interfaces now active across Inch Cape. The completed wind farm will sit around 15km off the Angus coast, with generated power travelling approximately 85km to a new substation in East Lothian before entering the national transmission system. Turbine assembly, foundations, subsea cabling, offshore electrical connections, and onshore grid works are therefore moving forward together rather than as isolated stages.
The choice of the V236-15MW places Inch Cape among the first UK projects to move into construction with the latest generation of higher-output offshore turbines. Larger machines reduce the number of turbine positions required for a given project capacity, but they transfer more engineering and logistics risk into each individual component. Blades, nacelles, tower sections, cranes, vessels, and port infrastructure all become larger, while damage or delay to a single item carries a greater consequence for installed capacity.
That is why ports sit increasingly close to the critical path of offshore wind delivery. Dundee has to absorb hundreds of large components, convert them into installation-ready sets, and release them at the pace demanded by Wind Mover without allowing the inflow of new hardware to disrupt assembly. Gigawatt-scale projects are discussed in terms of national generating capacity, but their construction performance is determined through far less glamorous sequences of lifts, inspections, cable operations, vessel movements, and commissioning tasks.
Inch Cape’s Dundee campaign will provide a practical UK test of that larger-machine delivery model. By the time Wind Mover begins its four-turbine installation cycles in November, the port will have become one of the principal interfaces between the project’s manufacturing supply chain and its offshore construction programme. The engineering challenge is no longer whether the components exist, but whether hundreds of them can be moved, assembled, commissioned, and loaded out in the sequence required to turn them into operating generation.
