WHAT'S HAPPENING ON SITE
Onshore converter station
Civil engineering contractors contracted to GE's Grid Solutions have been onsite since spring 2022, readying it for the installation of the converter station's state-of-the-art electrical infrastructure. Work is making visible leaps forward with the converter station buildings now almost weathertight and ready for fitting out.
Sofia is keen to minimise disruption to those living nearest the site and part of this has involved re-shaping the northern of two mounds that separate the converter stations’ site from Lazenby Village. As well as being reshaped, it has also been planted with trees, shrubs and wildflowers. The second phase of reshaping, on the southern mound, is now underway. The reshaped mounds will be an improved barrier to the construction activity and will visually screen the two new converter stations and the Wilton International site.
400kV AC cable route
A second GE contractor, VolkerInfra has carried out duct installation for the two-kilometre 400kV AC cable route from the converter station to the National Grid substation at Lackenby.
The onshore civil engineering work for the export cable route is progressing at pace. J. Murphy & Sons Ltd. has completed most of the duct installation in readiness for the project’s export cables to be pulled through. Work on the construction of tunnels which will be used to take the export cables underneath the railway bridge at Redcar Road has recently been completed, with transition bays either side of the tunnels now under construction.
Regular drone surveys of the converter station and both cable corridors will be carried out throughout the works to monitor progress.
At the landfall the teams are working on the one-kilometre horizontal directional drills from the construction compound opposite the beach near Marske-by-the-Sea, Teesside. Drilling work was on hold over winter but the site has remobilised and the final drills are now complete.
