ALE has successfully installed four shunt reactors and transported and installed two transformers for an onshore substation in north east Scotland, UK.
Firstly, ALE was tasked with offloading four shunt reactors, weighing 57t each, and positioning them onto their foundations. In order to lift the reactors, ALE used a 350t capacity mobile crane in four separate crane positions. This was completed in two days.
The next phase of the project involved discharging the two transformers, weighing 193t each, from a coaster vessel at Buckie harbour using a 600t capacity crane in one day. One transformer was placed into temporary storage at the harbour using 10 axle lines of SPT and the second transformer loaded directly to the 16 axle AL50 girder frame trailer.
Using the AL50 girder frame, the first transformer was transported from Buckie harbour to an onshore substation for an offshore windfarm, approximately 20 miles away. The route passed through a town centre where traffic management was arranged with the local authority. Once on site, the transformer was offloaded from the girder frame trailer and installed onto its foundation.
The second transformer was then transhipped from the storage location at Buckie harbour into the girder frame using the SPT and ALE repeated the transport operation from the harbour to the substation site. The installation of the second transformer was completed eight days after the arrival of the coaster vessel into Buckie harbour.
ALE needed to engage with third party authorities and the client to ensure the planning, permissions and consent conditions were met.
The detailed planning for the operational phase took ALE approximately two months to complete. SOURCE: ALE
