WHAT'S HAPPENING ON SITE
Onshore converter station
Civil engineering contractor Jones Bros. Civil Engineering UK handed the site to GE’s Grid Solutions and its onshore converter station sub-contractor Kier Infrastructure in spring this year. Jones Bros. had included provided a level load-bearing stone platform for both the Sofia and neighbouring Dogger Bank C converter stations; two new accesses to the site with associated bellmouths; welfare and laydown areas; drainage system, and associated utilities. New welfare facilities have been established to the north of the site, roads created within the site and the foundations for the storage, valve halls and service buildings are underway.
Sofia is keen to minimise disruption to those living nearest the site and part of this has focussed on re-shaping the mounds that separate the converter stations’ site from Lazenby Village. The reshaped mounds will be an improved barrier to the construction activity and in the longer term they will visually screen the two new converter stations and the Wilton International site. The north mound has been reshaped and planted with trees, shrubs and wildflowers. The second phase of reshaping, on the southern mound, is now underway.
A second GE contractor, VolkerInfra is also now onsite and so far has stripped the topsoil 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 also now well underway. J. Murphy & Sons Ltd. has established construction compounds at landfall and near the A174 between Saltburn and Redcar and the cable corridor has been fenced off.
Regular drone surveys of both the converter station and the cable corridor will be carried out throughout the works to monitor progress.
