580 Tonnes of Transformers for Pathfinder Substation Project
Collett, in collaboration with GE Vernova, has successfully transported and installed four 145Te Transformer as part of the Pathfinder Substation project.
The Pathfinder project involved the transport, heavy lift and final offloading, positioning and installation of four 145 Tonne transformers from Buckie Harbour to Pathfinder, Blackhillock Beatrice Onshore Substation.
The project required meticulous planning and execution to manage the transportation of each transformer, which measured 7.5m L x 3m W x 4.3m H. The transformers arrived at Buckie Harbour via coaster vessel and were discharged using a 500 Tonne TEREX DEMAG TC3200 crane. The first two transformers were stored on stools at the harbour, while the remaining two were prepared on trailers for transport.
Transported on Modular 12-axle flat top trailers
Each transformer was loaded onto modular 12-axle flat top trailers for transportation. The first two transformers were then transported from Buckie Harbour to the substation, accompanied by a police escort and our pilot car escort fleet.
The transformers were delivered in pairs, travelling in convoy to ensure smooth and efficient transportation.
Upon arrival at the site, each transformer was transhipped onto an 8-axle Self Propelled Trailer (SPT) to manoeuvre the tight site access. Navigating the site roads, the trailer was aligned with each respective plinth.
Our Heavy Lift Team had pre-arranged the necessary jacking and skidding equipment. Each transformer was jacked and skated into position onto their respective bunds, with final positioning achieved using precise positioning plates. The same process was repeated for all three remaining transformers.
Comprehensive Engineering and Preliminary Works
Our expertise extended beyond transport to include comprehensive engineering and preliminary works. The engineering drawings covered transport logistics, jacking and skidding procedures and ground pressure calculations. The preliminary works, managed by our Projects Department, involved a detailed route survey, permit applications, tree trimming and cable height surveys. A notable aspect of the project was the construction of a temporary bridge over a culvert using steel plates, organised in coordination with Moray Council.
Thierry Van Cayseele, Senior Logistics Manager at GE Vernova commended Collett on their involvement in the project stating:
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. 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. Congratulations to all the team!
