Metadata: 2013, VSH, Walney Extension, Export Cable Landfall HDD Technical Assessment
Abstract:
Visser & Smit Hanab (VSH) have been appointed by DONG energy (DE) to provide a high level assessment of the export cable landfall(s) associated with the extension to the existing Walney Extension Offshore Windfarm. The project involves the landing of 220kV export cable systems. It is intended that the cable connections shall be installed by means of Horizontal Directional Drill (HDD), exiting onto the beach within the intertidal zone, beyond which the cable will be buried beneath the sea bed out to the Offshore Windfarm. The HDD option is driven by the sensitive salt marshes at the landfall location and the need to cross the sea defence structure. This report is intended to provide a high level overview of the viability of installing the landfalls by means of HDD at the above location. The study will take into account the design of the HDD profiles, soil conditions, site constraints and set up and pipe stringing locations, based on the available data.

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | A site visit was attended by Bryan Lynch of DE, Jorn Stoelinga and Rebecca Cooke of Visser & Smit Hanab on 14th November 2013. Access and local conditions were evaluated at the site. The Horizontal Directional Drilling operation is essentially a three staged process, consisting of the pilot hole, reaming phases and finally the pull back of the product pipe. See section 4 'Methodology' for more information. |
