Pan-European map showing relative suitability score for Pile foundations translated from EMODnet Bathymetry water depth (offshore wind)

Pan-European water depth suitability map, derived from EMODnet (European Marine Observation and Data Network) Bathymetry data, showing the relative suitability for offshore wind pile foundations. The relative scoring system is from 0 (null) and 1 to 5 (i.e., high to low suitability, respectively), resulting in regional water depth suitability map for pile foundations. Null values represent hexagons that extended too far inland (e.g. estuaries) and thus don’t overlay the bathymetry map, however are kept in for information. A score of 5 (low suitability) is given to values >=0 and over 80 m. A score of 3 is given to 60-80 m. A score of 2 (higher suitability) is given to 10-50 m. The scoring system is a relative suitability scale, defined by BGS (2014), a commercial project undertaken with The Crown Estate. The original water depth (EMODnet Bathymetry) data has been translated into Hex maps due to the various data resolutions of the bathymetry datasets. Hex maps permit spatial screening of suitable license areas over vast areas and provides the end-user with an understanding to the level of uncertainty regarding the final maps. This pan-European digital GIS product is produced by the British Geological Survey (BGS) and forms part of a series of maps that define domain parameters related to marine geotechnical conditions, focusing on water depth and suitability for foundation installation. Water depth is a critical parameter influencing the selection and design of foundation systems for offshore infrastructure. Water Depth is a domain-type to support early-stage site assessment, engineering design constraints and risk evaluation processes in offshore development projects. The data is useful for marine spatial planners, wind farm developers, and research institutions who would like to understand the suitability of different foundation types for various water depths at a regional scale.

Data Quality

Creation of ‘H3’ hexagon grids, which is a global grid system for indexing geographies into a hexagonal grid (https://h3geo.org/). 6—Hexagons used for regional maps, with an average area of 36.129062164 square kilometers. Aim of hexagon conversion: Each hexagon to summarise the percentage of each hexagon taken up by lower, medium, higher complexity (and null), with the accompanying attributes that went into determining that level of complexity attached to each portion of the hexagon. Bathymetry map methodology: • Exported the hexagon grids (H3 hexagons, resolutions 6) that intersect with the EEZ, using Select by Location and then exporting the selected hexagon cells as a new shapefile (Bathymetry_H3_hex_res6). • The bathymetry layer had to be converted to an integer raster (as opposed to floating point) to be able to use the zonal statistics tools. • Used Zonal Statistics as Table tool (Spatial Analyst > Zonal Toolset) with the following settings: 'Auto detect' for percentile interpolation type. • Then water depth maps using the EMODnet Bathymetry layer was provided for Suction Buckets, Piles, Gravity-based structures and Floating wind farms. The method involves selecting each class of values in the table above and giving them their associated score. NB: The bathymetry map provides water depths as negative values i.e. -15 = 15 m below mean sea level, therefore the ranges in the table above are referring to negative values in the GIS data. To make processing simpler, all positive values in the GIS data were first given a value of -9999, then the whole field was multiplied by -1 to make all valid water depths positive. The MIN field was used for water depths as this contains the deepest values.
