2012, EGS, Walney Offshore Wind Farms, May Post-Construction Survey

Description

In May 2012 EGS (International) Ltd was contracted to undertake a bathymetric survey in
the post-construction (operational) phase of the project to determine whether there are
any changes to seabed morphology at the wind farm site including inter array cables and
along the export cable routes. In addition the survey covered three locations where debris
from wind farm construction has been lost to the seabed. To meet this objective EGS
conducted a multibeam high frequency bathymetric survey combined with seabed mapping
and sub-surface hazard identification using side-scan sonar (SSS) in conjunction with a USBL
system, across each of the proposed WTG, substation locations and export cable routes over
the Walney Offshore Windfarm 1 & 2 sites.
