UK, Halifax: On behalf of Hyundai Electric UK, in conjunction with National Grid, Collett Transport has delivered two 178 Te supergrid transformers from Tilbury Dock in Essex to National Grid’s Biggleswade substation in Bedfordshire. Each transformer was 9 m long, 5.4 m wide and 5 m in height, together with the trailer, a total vehicle length of 66 metres.
Collett utilised a 250 Te capacity Goldhofer girder bridge trailer to facilitate the movement of the two transformers, and the entire project took place over two weeks. The transport happened on two consecutive Sundays.
Prior to the transport, the company’s Projects and Consulting Departments provided comprehensive planning and site visits to strategise the route. With Collett having undertaken all ship chartering operations, the transformers arrived at Tilbury Dock. The first transformer was discharged from the vessel onto the girder bridge trailer and lowered onto stools in a secure storage area to await transport. The second transformer was discharged directly onto the girder bridge trailer, in preparation for the delivery to commence. Collett then travelled along the 76-mile route in approximately 8 hours, accompanied by its in-house escort vehicles and police escorts.
Upon arrival, Collett was responsible for offloading the transformer. Having previously undertaken detailed planning, its Heavy Lift Team utilised its heavy duty jacking and skidding equipment to skid the transformer from the trailer onto the final plinth. The girder bridge was then de-mobilised and returned to Tilbury Dock to load the second transformer, which was delivered to the site where it was once again offloaded onto the final plinth.
The 400 kV substation includes two transformers that are needed to power the local area. The substation will initially boost power capacity by 80 MW, allowing for future growth in the area.
