441 Wind Turbine Components Delivered to North Kyle Wind Farm
Collett has successfully delivered 441 wind turbine components to North Kyle Wind Farm, a project comprising forty-nine Vestas V136 turbines
Located in East Ayrshire, Scotland, the North Kyle Wind Farm represents Collett’s third-largest onshore wind farm transport projects to date and marks a major milestone in our renewable energy portfolio.
Deliveries commenced in June 2024 and were completed in April 2025. The project began with blades arriving at Glasgow’s King George V Dock and other turbine components at the Port of Ayr. Collett received the first shipment in April 2024 and continued with subsequent shipments until late February 2025, following the delivery schedule. Blades departed from KGV Dock and other components from the Port of Ayr, traveling 65 miles and 34 miles respectively to the construction site, following the planned delivery schedule.
To manage the scale and complexity of this project, we had to apply a highly coordinated approach We split the deliveries into Phase A and Phase B, with Phase A delivering 28 turbines via the east side and Phase B covering 21 turbines via the west side. We transported the longest components, 67-metre blades, on Super Wing Carriers. Base and mid tower sections were transported on Nooteboom clamp trailers, with 5- to 8-axle step-frame trailers used for delivery of nacelles, hubs, drive trains and top tower sections.
Phase A commenced in June 2024, delivering 252 components via Entrance 1 on the east side for 28 turbines. To accommodate the large components, our team worked closely with stakeholders to pre-plan site roads and optimise delivery sequencing, ensuring we could manoeuvre all components efficiently to their respective pads.
In September 2024, a major disruption occurred on a section of the A713, blocking access to Entrance 1. The damage, which began as a crack in the road few years ago, widened and lengthened during investigations and eventually in September, resulted in the Council shutting down all abnormal load transport along this route.
Working in close collaboration with Brockwell Energy and Jones Bros Civil Engineering, our team swiftly rerouted the remaining deliveries via Entrance 2 on the west side. Collett engineers supported Jones Bros Civil Engineering to produce updated swept path analysis reports and conducted further route surveys to verify the revised access points and expedited route modifications originally intended for Phase B. These changes allowed us to resume deliveries via Entrance 2 on the west side, accessed from the A76, reducing the impact on both the delivery schedule and wind farm’s completion date.
Despite adverse winter weather, including snow and ice, we successfully delivered the remaining Phase A components by December 2024 while maintaining the highest safety standards.
Phase B began in January 2025 and involved delivery of the remaining 189 components for the final 21 turbines. Once again, adverse weather conditions persisted through to the project’s conclusion. Despite weather-related obstacles, the final components were delivered to their respective pad by April 2025, officially concluding the project, experiencing only minimal delays to the schedule.
All deliveries were carefully scheduled, with three delivery slots per week allocated by police. Each movement was supported by our own escort fleet, police escorts and a dedicated on-site team consisting of a supervisor, six trucks, three escort vehicles and a tow truck.
Ahead of transport operations, our Consulting Department undertook comprehensive preliminary works, including detailed route surveys and swept path analysis to identify requirements for tree trimming and street furniture removal. Road closures and significant roadworks required close coordination with stakeholders such as Ayrshire Roads Alliance and the AMEY trunk road authorities, ensuring deliveries continued safely along the specified route.
The North Kyle Wind Farm represents another milestone in our track record within the renewable energy sector. Despite operational challenges and weather-related obstacles, we successfully delivered all 49 turbines, helping power Scotland’s transition to clean energy. Once operational, the North Kyle Wind Farm will have an installed capacity of 220.5 MW, generating enough renewable energy to power approximately 183,900 homes across the UK.
Paul Worth, Project Manager at Collett & Sons, commented:
“The North Kyle project was a real challenge with large components, roadworks, winter weather and complex site access to navigate. When the A713 was closed for abnormal load transport in September, our team had to quickly rethink the delivery plan and reroute via Entrance 2. Seeing everyone adapt so efficiently and still deliver all 441 components with minimal delays really highlighted the skill, planning and teamwork we have at Collett.”
