The aim of the survey was to investigate anything which might influence integrity strategies, including scour, debris, condition of WTG base and cable protection covers etc. Survey objectives: MBES Bathymetry and Pseudo Sidescan: Utilising a Multibeam Echosounder, survey the WTGs, OSSs & Export Cable to provide: ▪ 0.5m grid and 0.5m XYZ ▪ 1m grid and 1m XYZ ▪ 5 hits per 1m ▪ 100% coverage Once published, there will be no limitations on public access.

Bathymetry 2025-11-27 revision This series has been Quality Assured so that it is compliant with the aforementioned MEDIN Guidelines and thus contains the mandatory components. In some instances, this compliance will not be feasible. True Commission Regulation (EU) No 1089/2010 of 23 November 2010 implementing Directive 2007/2/EC of the European Parliament and of the Council as regards interoperability of spatial data sets and services 2010-12-08T00:00:00 publication Conformity with the Commission Regulation (EU) No 1089/2010 was either not relevant to this dataset or not a requirement of the Marine Data Exchange for the creation and submission of this dataset ; therefore, conformity has not been assessed and cannot be declared True series The survey was performed using USVs of the model type XOCEAN XO-450. The USVs were fitted with the equipment detailed in Table 8. They were fully unmanned and enabled autonomous survey operations with the survey team onshore. The USVs were transported to site on a trailer and then deployed into the water via a crane. The USVs sent back live 4K video for watchkeeping purposes. The survey computers on the USVs were remotely connected and gave complete access to survey acquisition in the same way as on a traditional manned survey vessel. Prior to mobilisation to the survey site, the survey systems were calibrated as detailed in the MAC reports. The survey was performed to maximize survey efficiency. Multibeam Echo Sounder (MBES) data was collected in NavAQ acquisition software. The Primary Reference Position (online) was provided by an Applanix POS MV system, augmented with PPP corrections from Fugro Marinestar in real time to establish a horizontal position accurate to less than 0.10 m, and a vertical position accuracy to less than 0.15 m. The MBES, Navigation (position, attitude), and SVP data was merged and georeferenced in NavAQ. Data from all sensors were recorded in raw data files. An online survey grid was generated in real time for online QC.
