Data was acquired during September to November 2018. The purpose was to fulfil the asset integrity reporting requirements namely bathymetric understanding and 2017 vs 2018 bathymetric comparisons of change at the site of the offshore substation, the subsea route that follows the two export cables, all turbines and IACs. The surveys were conducted onboard the EGS owned coastal survey vessel ‘EGS Watchful’, which operated on a 12hr basis from Fleetwood Marina and Orsteds operational docking facility at Barrow-in-Furness. Vessel mobilisation, calibrations and verifications began between 4th and 14th April 2018 whilst the vessel was in Ramsgate and were then completed offshore Barrow after the vessel was road transported to site. Survey operations commenced at WDS01 on 30th September 2018 and concluded on 22nd November 2018. Once published, there will be no limitations on public access.

In some instances, this compliance will not be feasible. True series Survey acquisition was carried out using the EGS Watchful, which is permanently mobilised with a suite of hydrographic equipment. The hull-mounted Kongsberg EM2040C Multibeam Echo Sounder (MBES), the Applanix POS MV 320 and the C&C Technologies C-Nav 2050 were calibrated and verified in accordance to the manufacturers’ guidelines. Survey data acquisition onsite commenced on 30/09/2018 and was completed on 22/11/2018. Data QC was carried out to ensure full coverage was achieved before demobilisation. On 23/11/2018, the vessel was demobilised and the data returned to the EGS office.
