Description

Osiris Projects were commissioned in July 2012 and February 2013 by Navitus Bay Development Ltd to carry out a detailed hydrographic and geophysical cable route development survey for the Navitus Bay windfarm development, offshore Dorset. The main objectives of the surveys were:
 Measure seabed topography and morphology and identify the nature of the
seabed sediments.
 Undertake shallow geophysical surveys using sub-bottom profiler to identity
sub-seabed geology, to provide data for cable burial assessment.
 Identify the location, extent and nature of any impediments to the installation of
the export cables such as wrecks, sea floor debris, rock outcrops, etc.
All of the objectives were planned to provide additional survey information to the
previously undertaken works at the site, ahead of the project’s Environmental Impact
Assessment submission. These objectives were achieved by utilising multibeam echo
sounder, side scan sonar, marine magnetometer and surface-towed ‘boomer’ subbottom
profiler, run simultaneously on all survey lines.
