Please keep clear of and do not
damage subsea cables/structures. You risk the loss of your gear and
catch, and international communications can be disrupted. These
cables carry high voltages and can be dangerous to life. Many
cables have high breaking strains, some over 70 tonnes. Cables will usually lie buried in the seabed,
although because the seabed can move, there is no guarantee they
will remain in the same place.
If you do snag a cable, or find
yourself in difficulty within a wind farm, make sure you follow the
emergency procedures below, to safeguard your vessel and your

Advise HM Coastguard of your situation or call the 24 hour
Emergency Number associated with the cable/structure and state that
an incident is occurring concerning a subsea cable/structure.
The closer to the surface a subsea
cable is lifted when fouled by fishing gear, the more danger there
is to the fishing vessel.
If it is thought prudent to slip,
or cut one or both warps or bridles, in an attempt to clear a cable
from the fishing gear, always lower the gear to the seabed first.
Never attempt to slip anything bearing excessive weight.
