Dogger Bank South (DBS East) Offshore Wind Farm

09 Nov 2021: Scoping report submitted to the Secretary of State on 9th November 2021. Early project design indications; Up to 200 turbines across the two sites Size 15MW-24MW It is estimated that the indicative maximum rotor diameter would be 326m Three areas being considered as potential landfall locations: - between Sunderland and Hartlepool; - between Bridlington and Spurn Point; and - between Grimsby and Skegness. Foundation Types under consideration - monopiles (up to 14m diameter) - suction bucket foundations (mono-bucket); - gravity based foundations; - jackets on pin piles; - jackets on suction buckets; and - gravity based jacket foundations. Up to 600km of array cabling; Up to 5 offshore substation platforms (OSPs) and/or offshore converter platforms (OCP) Export cabling: Either HVAC or HVDC depending on the location of the onshore grid connection point(s). If HVAC is chosen there could be up to four HVAC cables per Project, with a diameter of approximately 240mm. For HVDC there could be up to two HVDC cables per Project, with a diameter of approximately 145mm. If HVAC is chosen there may be a requirement for reactive compensation platforms along the offshore export cable route. If required, these could be located above the sea surface or on the seabed. It is anticipated that the assets would have an operational life of 30 years. As part of the Offshore Wind Leasing Round 4 the developers will enter into a seabed lease for up to 60 years, this allows sufficient time for two complete asset lifecycles.
