Two 239te transformers successfully delivered
Allelys have recently completed the successful delivery of two transformers from Buckie Harbour, Banffshire in Scotland to Moray West Onshore Converter Station. The units both weighed 239te and measured 12.3m long, 4m wide and 4.6m high.
Prior to the operation, extensive planning and engineering works were completed to overcome the harbour’s restrictive layout and limited space.
Detailed transport and installation solutions
Allelys also completed detailed route surveys along the route, with swept path analysis on the most restrictive areas also identifying necessary street furniture removal requirements, which would ensure the load was delivered safely and securely to site.
The transformers were offloaded from the vessel using an LG1750 lattice boom crane and loaded directly onto SPMTs. The first unit was then transshipped onto a 24 axle girder frame trailer and laid into load hangers to allow for a more suitable offload procedure due to the long load length. 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 18m onto the designated plinth.
Efficient timing plans
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.
“This project has been a great example of Allelys finding an efficient and effective solution to support the power sector. The tight restrictions around the harbour are a challenge for loads such as these. However, our knowledge and experience of route planning and management ensured that we engineered a suitable solution”. Commented Jordan Heath, Project Manager at Allelys.
