MMT, contracted by Offshore Marine Management (OMM), has completed geophysical, geotechnical and cable crossing surveys in preparation for the installation of the COBRAcable, which will connect the Netherlands and Denmark.
The project was completed with a four-vessel solution between early September and late November. The M/V Askholmen performed Shallow Water Geophysical Survey at the landfalls in Eemshaven, Netherlands and Fanö, Denmark.
The Coastal Chariot from Acta Marine performed shallow water Geotechnical Survey utilizing MMT’s CPT and Vibro Corer. The M/V Icebeam performed Offshore Geophysical Survey and Geotechnical Survey with the Stril Explorer performing Cable Crossing Surveys to establish Depth of Burial using the Orion Cable Tracking System. The Stril Explorer also undertook the CPT and Vibro Corer works at the end of the project.
The COBRAcable route (appr. 325 km) is proposed to be laid across the Southern North Sea. It is a cross-border project of European significance and is part of the EU Economic Recovery Plan, designated as a Project of Common Interest (PCI).
The project was awarded under OMM’s framework agreement held with TenneT for the provision of survey services.
