An Anglo-Norwegian joint venture of Seacore and Eidesvik Subsea began a marine site investigation under the Strait of Gibraltar in January to assist in the design of a proposed tunnel between Spain and North Africa.
The work will take between 100 to 200 days.
Seacore has mounted its own R100 drill rig on to the vessel Kingfisher and drilling and core sampling will be carried out to a depth of 350m below seabed.
Special vortex shedding equipment and seabed borehole re-entry equipment will enable the drilling to withstand the exceptionally strong currents experienced at water depths of up to 300m.
The full capability of the vessel and drill rig will be required to cope with the anticipated extreme conditions.
