What is being bought
As part of the ongoing Operations and Maintenance, an interim depth of burial marine survey
needs to be produced which is specific to the parts of the cable route which demonstrates
industry best practice for bathymetric and geophysical surveys. The general requirement is
for a marine bathymetric and geophysical survey along an approximately 390km route
comprising two separated cables from Hunterston in Scotland to the Wirral, England over an
approximately 80m wide corridor. The interim surveys are of areas of interest e.g. crossings,
areas of mobile sediments and intense fishing etc. and comprise approximately 30-50% of
the total route length.
