Collett Delivers Components for Burnfoot Hill East Wind Farm Extention

All turbine components for the Burnfoot Hill East wind farm extension have been successfully delivered from the Port of Grangemouth to Tillicoultry, Clackmannanshire.

The extension involved an additional three Vestas V112 wind turbines, each featuring 55m blades and 69m high towers. As the components arrived into the port, Collett’s experienced Projects Team planned the vessels discharge, transferring all components to their dedicated port side depot for storage before onward transport.

Prior to delivery, preparation for the 60 mile journey began with Collett undertaking an authorised ‘test drive’, utilising their Nooteboom SuperWing Carrier with a pre-determined configuration to simulate the transportation of the 55m blades. Once the route had been approved, Collett pre-delivered the majority of the components, including the blades, nacelles, hubs, drive trains and the base and mid tower sections. Finally, the top tower sections followed a strategic ‘just in time’ delivery schedule in line with the wind farm’s installation programme.

The nacelles, weighing 80t, were the heaviest components delivered to site. The blades, although the lightest were also the longest components delivered weighing 8t and measuring 55m. The towers were delivered in three sections, the heaviest being the base section weighing 55t and measuring 16m. The middle section weighed 43t and measured 21m and the longest but the thinnest section of each tower weighed 44 Tonne and measured 30m.

To overcome the components complex variety of dimensions, Collett employed their diverse fleet of specialist equipment. This included SuperWing Carriers, tower clamp trailers (specifically designed for the transport of wind turbine towers) and their five & six axle extendable semi-trailers.

The journey included a combination of motorways, dual carriageways and A-roads, including a harsh 90-degree bend to cross Backhill bridge on approach to the construction site. However, with the assistance of the SuperWing Carriers, which provide a 60-degree steering angle and significantly more suspension travel (lift/lower) for extra ground clearance, the experienced operators from Collett and Sons, Ltd. delivered all component safely to site.

Burnfoot Hill East Wind Farm was formally consented by the Clackmannanshire Council in March 2019. The wind farm took around 12 months to complete and can produce enough electricity for up to 6,000 homes. The wind farm is an extension to the existing 21 turbine Burnfoot Hill, Burnfoot Hill North and Rhodders wind farms, operated by EDF Renewables, one of the world leaders in renewable energy, all located in Clackmannanshire, Scotland.
