HVDC ±320 kV export cable system for Dogger Bank B, comprising an approximately 174 km subsea route and 30 km onshore route between the Dogger Bank B offshore HVDC platform and National Grid’s Creyke Beck substation in East Yorkshire, installed as a symmetric monopole with two parallel cables.
NKT acted as the main turnkey contractor for the high-voltage direct current (HVDC) export cable systems for the Dogger Bank offshore wind farm, including the Dogger Bank B offshore transmission link to Creyke Beck substation. Under a preferred supplier agreement and subsequent contract, NKT was selected by the Dogger Bank Wind Farm joint venture to deliver and install the onshore and offshore 320 kV HVDC export cable systems for phases A and B (Creyke Beck A/B) and later C. For Dogger Bank B, NKT is responsible for manufacturing and installing the subsea export cables from the Dogger Bank B offshore HVDC platform to landfall on the Yorkshire coast, and the onshore HVDC cables from landfall to National Grid’s Creyke Beck substation. The scope covers turnkey delivery, including production of all HVDC cable required and offshore installation using the cable‑laying vessel NKT Victoria. Cable installation for Dogger Bank B followed the Dogger Bank A campaign within the project’s 2019–ongoing construction schedule.
