Collett hauls 81 components for Twentyshilling wind farm in Scotland
The abnormal loads specialist Collett has completed the delivery of 81 individual wind turbine components for Twentyshilling Wind Farm, located approximately 4.8 kilometres south of Sanquhar, in Dumfries & Galloway, Scotland.
Collett has been tasked with planning and delivery of the nine Vestas V117 turbines. The deliveries from King George V Dock operated by the Clyde Port Authority started in June 2021. Each of the components for each complete turbine, the three towers sections, three blades, nacelle, drive train and hub, would require specialist transport logistics for the 170 mile journey to site.
During the route survey, several route modifications have been identified. In order to make a left turn some two miles from the construction site, a turning head construction has been proposed in order to enable the 27 blades measuring 57 metres in length to navigate the turn. The turning head was constructed at Eliock Bridge ahead of the component deliveries.
Collett calls on specialist fleet for the job
Utilising their specialist fleet, Collett employed super wing carriers to transport the 57-metre, 14.9-tonne blades. In addition, the use of these specialist super wing carriers allowed Collett to overcome issues of the vertical alignment from the main road to Eliock Bridge, avoiding the need for works to be undertaken on the listed structure.
For the other components, the 25-metre long bottom and 26-metre middle towers, with weights of 67 and 44.5 tonnes Collett utilised specialist clamp trailers, whilst the remaining components, the top towers, nacelle, drive trains and hubs were transported using Collett’s 5 and 6 axle step-frame trailers.
Working to a detailed delivery schedule, produced in line with the site construction needs, over a period of 14 weeks the Collett team delivered each of the components from King George V Dock to the Dumfries & Galloway
construction site. All components travelled under Collett escort, with Police escorts in attendance for the blades, tower sections, nacelles and drive trains.
All deliveries to the 38MW Twentyshilling Wind Farm are now complete with the nine Vestas V117 140 metre tip turbines expected to be fully operational in 2022.
