Transportation of 3 super grid transformers and 2 shunt reactors
Allelys were contracted to transport three 272te super grid transformers and two 77te shunt reactors from Peterhead Port, Aberdeenshire to Moray East Substation, New Deer, Aberdeenshire.
All of the units were shipped to Peterhead Port where Allelys used a Liebherr LG1550 heavy lift crane to offload the units from the delivery vessels to the port side storage.
Our 350te capacity ‘Faktor 5.5’ girder frame was utilised, with 10 modular axles at each end of the frame, to transport the super grid transformers. The unique design allowed the team to self-load the trailer without any outside assistance for each movement. The combined delivery weight, including the two MAN prime movers, was 484te and had an overall length of 66.7m.
The route
The transportation from Peterhead Port to Moray East Substation used the A90 before turning off onto smaller ‘A’ and ‘B’ roads. Numerous structures on the route had to be checked and cleared for load bearing capacity, resulting in special manoeuvres and speed restrictions being put in place. Travelling through small Scottish villages and hamlets with such a large vehicle also drew a lot of attention from the public.
Each super grid transformer was offloaded to its final position at the Moray East Substation, using our own hydraulic skid system and synchronised jacking equipment.
The two shunt reactors were delivered to site on flat top modular trailers from Peterhead Port and were offloaded to their final position using a Liebherr LTM1500 mobile crane.
In addition to the transportation and installation, Allelys also provided a fully engineered and project managed solution.
