VBMS Prepping for Pre-Lay Grapnel Run at Dudgeon OWF

VBMS will be carrying out a Pre-Lay Grapnel Run (PLGR) operation as part of the preparations for the installation of the export and array cables for the Dudgeon Offshore Wind Farm, Kis-Orca reports.

The PLGR involves the vessel Anna-B towing a grapnel train arrangement over the seabed. The grapnel wire pulling the grapnel train will have a length of at least 4-5 times the water depth.

The vessel follows the cable route to hook in and recover all small debris like lost fishing nets, ropes and wires from the seabed, following the centre line of the planned export cable route with a tolerance of 10m to both sides of the planned export cable route, giving a 20m corridor. This work is done in order to clear the route prior to the installation of the export cable.

The Anna-B will arrive on location at or around 9 February 2016. The vessel will be working in the area for an expected duration of maximum 28 days.
