Function
Hydrographic surveys examine the impact of the floating offshore wind farm development on local sedimentation and coastal processes such as erosion. This is often part of the geophysical survey. These surveys are also part of the post construction monitoring during the operations phase.
What it costs*
About £1.9 for a 1 GW floating offshore wind farm.
Who supplies them
Various local construction companies with suitable vessels, equipment and expertise can supply this.
Specialist hydrographic survey companies such as Fugro, Gardline and MMT perform the surveys, and consultants such as ABPmer and HR Wallingford undertake the impact modelling.
Key facts
Understanding the sedimentation environment of the proposed site is of particular importance as it informs the scour characteristics of the site and subsequent protection measures required.
