Collett Handles Transformers for Scottish Substation (video)

British heavy transport specialist Collett & Sons has successfully handled four mammoth transformers for an onshore substation project in northern Scotland.

The so-called Pathfinder project for wind turbine maker GE Vernova involved the transport of the 145-ton components in pairs from Buckie Harbour on the Moray Firth coast to the Blackhillock Beatrice substation, a distance of some 27 kilometers. Collett was also charged with the lifting and final offloading, positioning and installation of the units, which measured 7.5 meters long, 3 meters wide and 4.3 meters high.

The transformers arrived at Buckie Harbour via a coaster vessel and were discharged using a 500-ton-capacity Terex Demag TC3200 crane. The first two components were stored on stools at the port facility, while the remaining pair were loaded onto modular 12-axle flat top trailers and carried to the substation site alongside a police escort.

At the site, each transformer was transshipped onto an 8-axle self-propelled trailer to maneuver the tight site access. The units were then jacked and skated into position onto their respective bunds, with final placement achieved using precise plates.

The planning of the project encompassed detailed route surveys, permit applications, tree trimming and cable height surveys. The project team also worked alongside Moray Council to build a temporary bridge over a culvert using steel plates.

“The transport and installation of the four transformers was a very challenging operation due to the unpredictable weather causing a delay of the vessel, requiring us to review the schedule every day,” said Thierry Van Cayseele, senior logistics manager at GE Vernova. “Nevertheless, Collett staff showed great resilience and understanding. Thanks to their adaptability and professionalism, the transformers were successfully and safely delivered to the substation site.”
