This dataset represents the external boundary of the areas of seabed within which Bidders can propose projects through the Round 4 leasing process.

This map represents all current live offshore agreements in English, Welsh and Northern Irish waters. The boundaries are a true reflection of what has been signed in the Agreements for Lease and Lease documents. Much of the agreements data shown in this map is available from the The Crown Estate Open Data portal.

This dataset represents all current offshore wind farm agreements in pre-planning, planning, construction and operational phases in English, Welsh and Northern Irish waters. The boundaries are a true reflection of what has been signed in the Agreements for Lease and Lease documents.

The suitability of areas for offshore wind development in the waters off England, Wales and Northern Ireland is the subject of ongoing assessment by The Crown Estate (TCE). In light of: i. the pace of technological change in the offshore wind sector; ii. the potential for future leasing as a response to UK Net Zero; and, iii. TCE’s responsibility to sustainably maximise the value of the seabed it manages, Everoze has been engaged by TCE to develop an updated methodology for characterising Key Resource Areas reflecting the latest and anticipated future technological developments in the sector out to a deployment date of 2040. A Key Resource Area (KRA) defines areas of seabed suitable for offshore wind development based on technology availability over a given timeframe. It is not intended to capture other factors vital to identifying suitability for development (e.g. other seabed uses, environmental constraints, etc.). These additional sensitivities will be considered in successive stages through further analysis by TCE in due course that build upon the KRA identification. In the context of a maturing sector, the methodology for KRA identification has moved away from classifying areas of seabed as Favourable, Limited and Marginal – as has been the case in previous KRA reviews - and towards identifying Technology Groups which characterise technical solutions for a given set of physical site drivers. This data presents the spatial analysis outputs of the criteria defined in the report by Everoze (Characterisation of Key Resource Areas for Offshore Wind – A Report for The Crown Estate, October 2020) for floating offshore wind and should be used in conjunction with the associated report which provides the context and justification to these spatial outputs. The study was run to the waters off England, Wales and Northern Ireland.Below are the criteria used for each floating wind Technology Group defined:TG1 – Conventional Anchoring-Moderate Sea State – Depth 50-250m, Quaternary Thickness >20m, Hs50 < 14mTG2 – Conventional Anchoring-Onerous Sea State – D 50-250m, QT >20m, Hs50 >14mTG3 – Complex Anchoring-Moderate Sea State – D 50-250m, QT 5-20m – Hs50 <14mTG4 – Complex Anchoring-Onerous Sea State – D 50-250m, QT 5-20m, Hs50 >14mTG5 – Pile/Socket Anchoring-Moderate Sea State – D 50-250m, QT <5m, Hs50 <15mTG6 – Pile/Socket Anchoring-Onerous Sea State – D 50-250m, QT <5m, Hs50 <15mThere is a global 9m/s minimum windspeed adopted. Datasets used in the analysis:Quaternary Thickness – BGSWind Speed – Met Office 2015 UK Offshore Wind ResourceBathymetry – Oceanwise Marine DEM 1 arc sec, and GEBCO World Bathymetry (in areas not covered otherwise)Metocean – ABPmer Hs50This data has been prepared by The Crown Estate using the criteria provided by Everoze Partners Limited in the report ‘Characterisation of Key Resource Areas for Offshore Wind’, October 2020.

The dataset on offshore wind farms in the European seas was created in 2014 by CETMAR for the European Marine Observation and Data Network (EMODnet). It is the result of the aggregation and harmonization of datasets provided by several sources. It is updated every year and it is available for viewing and download on EMODnet web portal (Human Activities, https://emodnet.ec.europa.eu/en/human-activities). The dataset contains points and/or (where available) polygons representing offshore wind farms in the following countries: Belgium, Denmark, Estonia, Finland, France, Germany, Greece, Ireland, Italy, Latvia, Lithuania, Netherlands, Norway, Poland, Portugal, Spain, Sweden and United Kingdom. Each point and polygon has the following attributes (where available): Name, Nº of turbines, Status (Approved, Planned, Dismantled, Construction, Production, Test site), Country, Year, Power (MW), Distance to coast (metres) and Area (square kilometres). The distance to coast (EEA coastline shapefile) has been calculated using the UTM WGS84 Zone projected coordinate system where data fall in.

SeaMaST provides evidence on the use of sea areas by seabirds and inshore waterbirds in English territorial waters, mapping their relative sensitivity to offshore wind farm and wave/tidal energy developments. Data were compiled from offshore boat and aerial observer surveys spanning the period 1979–2012. The data were analysed using distance analysis and Density Surface Modelling to produce predicted bird densities across a grid covering English territorial waters at a resolution of 3 km x 3 km. Coefficients of Variation were estimated for each grid cell density, as an indication of confidence in predictions. Offshore wind farm sensitivity scores were compiled for seabird species using English territorial waters in breeding and non-breeding seasons, according to the BDMPS (Biologically Defined Minimum Population Scales) project (http://publications.naturalengland.org.uk/publication/6427568802627584). The comparative risks to each species of collision with turbines and displacement from operational turbines were reviewed and scored separately, and the scores were multiplied by the bird density estimates to produce relative sensitivity maps.
