North Falls: landfall

Progress on the landfall search area

The offshore export cables are brought to shore at a location known as 'landfall'.

The previous consultation highlighted a landfall search area - the section of coastline between Clacton-on-Sea and Frinton-on-Sea - which was defined through a process of engineering and environmental review and assessment. The process took into account a range of constraints including designated sites, nature reserves, land use, historic features and technical feasibility.

The landfall selection process has continued following the confirmation of the grid connection location and further data collection and consultation. This work has resulted in a landfall compound zone (see map), within which the temporary construction compound would be located. The precise landfall location will be identified, from within this zone, and finalised in advance of the development consent application submission.

Construction works at landfall

Construction works at the point of landfall will comprise the installation of underground cable ducts using horizontal directional drilling (HDD) or another trenchless technique. This will be done from the landward side, with the drill exiting beyond the beach in the sub-tidal zone. This method will bury the cable ducts deep under Holland Haven Marshes Site of Special Scientific Interest (SSSI) and so avoid crossing the site at the surface. Once the ducts are installed underground, the offshore cables will be pulled through them, before being connected to the onshore cables at transition joint bays which will also be buried once construciton is complete.

Although there would be temporary disruption during the project construction, there will be no permanent above-ground building at landfall. The objective is to keep any disruption to a minimum through considerate construction activities including the use of the HDD installation methodology mentioned above.
