The heavy transport specialist, Collett & Sons, has delivered 216 components for 24 new Vestas V136 wind turbines. Limekiln wind farm in the Scottish Highlands is being built by Boralex as part of the Scottish Government’s plans to create 20GW of onshore wind power by 2030.
Collett’s team spent five months planning movements from Scrabster Port to the wind farm which is located around 45 minutes away. Preparation for the project included detailed route assessments, swept path analysis, street furniture removal, tree trimming and widening a sharp bend near the port.
A test route was carried out before moving the turbine components using an extendable trailer with a 15m rear projection to simulate blade length. For blade and tower section transportation, police escorts accompanied the team to the site after which time Collett’s escort fleet managed location movements around the wind farm to secure storage areas.
Different Nooteboom trailers were used throughout the project from May until October 2024. For blades up to 67m long, Collett used the Nooteboom super wing carrier trailer. New 3x7 Nooteboom clamps were used to move 74Te base tower sections. Smaller components including mid tower, top tower, nacelle, drive train, and hub were moved with a six-axle stepframe trailer.
Altogether, Collett had a team of three drivers, three steersmen, a project manager, site supervisor and tow truck operator to complete the job. The company also organised port operations including vessel berthing, component handling, crane offloading and vessel discharge. Initial deliveries were stored on site while later arrivals were planned around the wind farm’s construction schedule.
On completion, the Limekiln wind farm is expected to have a capacity of 108 MW. To put this in perspective, this is equivalent to producing enough renewable energy for 40,200 homes annually. By setting up this facility, the goal is to offset at least 65,000 tonnes of CO2 emissions every year using wind rather than other sources like gas or coal-fired power stations.
