Meticulous planning was required to move four 145-tonne transformers recently from Buckie Harbour to Pathfinder, Blackhillock Beatrice onshore substation. The heavy transport specialist Collett Transport completed the project in collaboration with GE Vernova. 

The project required meticulous planning and execution to manage the transportation of each transformer. The transformers measured 7.5 meters in length, 3 meters in width, and 4.3 meters in height. They arrived at Buckie Harbour via a coaster vessel and were discharged using a 500-tonne crane. The first two transformers were stored on stools at the harbour, while the remaining two were prepared on trailers for transport.

The transformers were loaded onto modular 12-axle flatbed trailers for transportation. The first two transformers were then transported from Buckie Harbour to the substation, accompanied by a police escort and Collett’s own pilot car escort fleet. The transformers were delivered in pairs, travelling in convoys to ensure smooth and efficient transportation.

Upon arrival at the site, each transformer was transferred onto an 8-axle Self-Propelled Trailer (SPT) to navigate the tight site access. The trailer was then manoeuvred onto the site roads and aligned with each respective plinth. The Collett Heavy Lift Team had already prepared the necessary jacking and skidding equipment. Each transformer was lifted and moved into position onto their respective bunds using the jacking and skidding equipment. Final positioning was achieved using precise positioning plates. This process was repeated for the remaining three transformers.

Collett’s expertise extended to comprehensive engineering and preliminary works, including transport logistics, jacking and skidding procedures, and ground pressure calculations. The project involved a detailed route survey, permit applications, tree trimming, cable height surveys, and the construction of a temporary bridge over a culvert using steel plates, in coordination with Moray Council.
