Scottish and Southern Electric’s Kintyre-Hunterston project has taken a major step forward with delivery of a 133t transformer but major ground engineering work was needed to get the vital equipment in place.
Main contractor Amec Foster Wheeler worked with Tony Gee and Partners and OTB Engineering to design an 8m high steel reinforced earth Ramwall embankment to overcome the incised valleys on the haul road route.
Successful design and construction of the embankment in less than 10 weeks enabled Allelys Heavy Haulage to deliver the 220/132kV transformer on schedule to substation contractors Seimens and Bam.
The Kintyre-Hunterston project involves reinforcement of the 132kV transmission network on Kintyre by developing a new connection between Carradale and a new substation at Crossaig.
Foundations for the 44 new towers that will carry a new 14.4km overhead line north from Crossaig and onshore cable ducting has now been completed. Work on horizontal directional drilling for the new subsea cable is now underway.
