Images: Collett transfers transformers to Scottish substation

Heavy freight expert Collett Transport moved the transformers from Buckie Harbour on the Moray Firth coast in northern Scotland to the substation in Blackhillock, near the town of Keith on behalf of client, GE Vernova, the energy-focused business unit of General Electric.

The transformers, measuring 7.5 metres in length, 3 metres in width, and 4.3 metres in height, formed part of the National Grid Pathfinder substation project at Blackhillock.

After arriving at Buckie Harbour via coaster vessel in April 2024, Collett used a 500 Tonne Terex Demag TC3200 crane to transfer the first two transformers from the vessel to storage at the harbour.

The remaining two were loaded onto modular 12-axle flat top trailers for transportation.

The transformers were then driven in pairs, nearly 15 miles, travelling in convoy to the substation, accompanied by a police escort and a pilot car escort fleet.

Upon arrival at the site, each transformer was transferred onto an 8-axle Self Propelled Trailer (SPT) to manoeuvre the tight site access.

Each transformer was then jacked and skated into position onto their respective bunds, with final positioning achieved using precise positioning plates.

Before the transformers could take to the roads, the entire operation had to be carefully planned.

Collett was responsible for applying for the required permits to transport the loads, drawing up a detailed route survey, trimming the trees along the route which could interfere with transport and surveying the heights of electricity cables.

The company was also responsible for building a temporary bridge over a culvert using steel plates, organised in coordination with Moray Council.

Preparation work also included ground pressure calculations, jacking and skidding procedures and engineering drawings.

“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, the transformers were successfully and safely delivered to the substation site.”
