Collett Delivers Wind Farm Components to Creag Riabhach Wind Farm.

Beginning in June, the Collett Team are today well underway with delivery of the 242 components for the  construction of 22 Enercon E115 E3 wind turbines at Creag Riabhach Wind Farm.

Currently under construction, Creag Riabhach Wind Farm is situated on the Altnaharra Estate, near Lairg in the North Highlands, and features twenty two turbines at a hub height of 67m and sixty six 57m blades.



Arriving at the Port of Nigg, the largest open port in the Moray Firth, Inverness, the components faced a 53-mile journey to the construction site in the North Highlands.  Having already undertaken a test drive of the route utilising a 48m trailer, complete with a 9m rear projection to simulate the loaded Enercon E115 turbine blades, the Collett Team had fully surveyed the route to ensure suitability.

Alongside highlighting any necessary route modifications and road widening requirements, the test drive also identified areas of street furniture removal, relocation of flower beds and lamp post removals to accommodate the wind turbine oversail.  Having modified the route for the passage of the blades, the longest of the components, the Team could ensure safe passage of all 11 components necessary to construct each complete turbine.



With this in place, Collett began the transport of the 66 blades, 66 tower sections, 44 stator halves and 22 nacelles, hubs and rotor centres the 53 miles from Inverness to Lairg.  Utilising a total of nine trailers across their fleet to accommodate the varying components, deliveries are now underway.  With cargoes ranging from 31t to 73t, the Team are employing the capabilities of Collett’s super wing carriers, clamp trailers, stepframes and 40ft flats to systematically deliver the components in line with the construction schedule.

Travelling in convoys of three, and utilising each of the trailer’s hydraulic capabilities to ensure a maximum traveling height of 4.95m throughout, the Collett Team employed manual steering and contraflow manoeuvres along the route, safely delivering the first of the components to the site.

On arrival at Creag Riabhach, due to site gradients, the dynamic nature of the weather and the subsequent site conditions, the Team employed the additional traction of a double-drive towing vehicle, travelling in front of the delivery convoys for the heaviest of the components.

Beginning in June, their Team have completed the delivery of components for four complete 115m rotor diameter turbines, with all 22 expected to be complete by September/October.  Once fully operational, Creag Riabhach Wind Farm will generate up to 72.6MW of clean, renewable energy, enough to power 36,000 homes.
