Description

Bibby HydroMap were commissioned by Blyth Offshore Demonstrator Ltd/EDF Renewables, in August 2018, to undertake a geophysical survey at the Blyth Offshore Demonstrator wind farm, located off the north-east coast of the UK at Blyth, Northumberland. The 41.5 MW wind farm is located approximately 6km offshore of Blyth and comprises five wind turbine generators configured in a single row. The survey was undertaken between 30/08/2018 and 14/09/2018. This survey, comprising the collection of multibeam bathymetry and side scan sonar data, marks the first of a 3-year monitoring program, which will be undertaken at 6 monthly intervals, and after any major storm events. The objectives of the survey program are to acquire survey data to a resolution that will: - Identify seabed debris within the construction area; - Identify changes to seabed morphology, to enable the evaluation of the effectiveness of installed scour protection and ratify predictions for scour development; - Inform the foundation and cable maintenance schedule; and - Satisfy the requirements of the Marine Licence. Data acquisition was undertaken from Bibby HydroMap’s own dedicated shallow draft vessel MV Proteus, equipped with a Dual head Norbit WBMs multibeam, Klein 3000 side scan sonar, POS MV MRU and CNAV positioning system.
