Offshore wind UK

(1) This dataset contains corridors of seabed that The Crown Estate has entered into an agreement upon with either a wind farm developer, an offshore transmission operator (OFTO), or a tidal site developer. There are two types of corridor within this dataset, a buffered centreline of a specified width or a bounding polygon created from a series of coordinates. The status of which is tracked in the "Defined" column. The buffered centreline corridors are 500 m wide and are exactly 250 m either side of the cable centreline (this represents the majority of The Crown Estate's cable agreements however there are a few minor exceptions to this rule). For export routes where there are a number of cables that are within 250 m of each other, the corridors are dissolved together to create one large agreement. The 500 m wide corridor consists of a 30 m wide designated area (DA) centred on the cable with the remaining area comprising of a dredging restriction zone (DRZ) (a further 235m either side of the cable). The Crown Estate still reserves rights to grant other activities within the DA (subject to the tenant's consent) and within the DRZ, however it undertakes not to grant rights for dredging in the DA or DRZ. This dataset has been clipped to exclude all of the seabed that falls within wind farm agreements areas, however overlapping rights do exist to allow the cable to be laid to the offshore substation. In some instances wind farm and tidal agreements are in place however the export cable agreements has yet to be signed. These routes may be in the public domain but have not been included in this dataset as no agreement is in place with The Crown Estate. For these sites The Crown Estate will implement cable agreements as developers bring forward proposed routes. This dataset is provided to the best of our knowledge, however we accept no liability on the accuracy of the information. (2) These data represent all offshore wind farms in pre-planning, planning, construction and operational phases in United Kingdom waters. Leasing rounds 1, 2 and 3 are included along with round 1 and 2 extensions, scottish exclusivity award applications, Demonstration wind farms and the Northern Ireland Offshore Wind Resource Area. The boundaries are a true reflection of what has been signed in the Agreements for Lease, and Lease documents.
