UK-based heavy haulage specialist Allelys has delivered two transformers, weighing 239 tonnes and measuring 12.3 m x 4 m x 4.6 m, from Buckie Harbour in Scotland to the Moray West onshore converter station.

Prior to the operation, extensive planning and engineering works were completed to overcome the harbour’s restrictive layout and limited space. Allelys also completed detailed route surveys, with swept path analysis on the most restrictive areas, identifying necessary street furniture removal requirements. 

The transformers were offloaded from the vessel using an LG1750 lattice boom crane and loaded directly onto SPMTs. The first unit was then transhipped onto a 24-axle girder frame trailer.  

Under police escort and with road closures in place, the first transformer was transported to site. After the unit was stooled off, the girder frame was then dismantled and able to return to collect the second transformer. Simultaneously, the first transformer was jacked down and skidded 18 m onto the designated plinth.  

The girder frame was rebuilt at the port and the second transformer was loaded, transported and installed using the same process and route as the first.  

Transporting the two units on consecutive weekends enabled Allelys to maintain an efficient timing schedule.
