Western HVDC Link: Cable installation update, December 2015

[Update – the work described below has now been completed.  This notice remains as part of the historical record of notices issued for this project.  Please refer to the most recent notice for an up-to-date record of the notices presently in force for this project.  This can be accessed via the project description page here.]

Mariners are advised that a 28km length of cable has been temporarily surface laid on the seabed along the Western HVDC Link cable route due to the recent bad weather.  This length of cable has been laid in the Irish Sea to the south of the Isle of Man.  A Notice to Mariners advising of the location of this cable can be downloaded here and is summarised below.

Surface laid cable

The surface laid cable lies between the following points:-

  • Start: 53°50.173’N 004°02.367’W
  • End: 53°53.514’N 004°27.040’W

The as laid cable installation details are given in the Notice to Mariners, along with a chart illustrating its location.  The surface laid cable runs parallel to, and 20m north, of the most recently laid section of the Western Link cable.

Vessels are requested to pass at a safe speed and distance and fishing vessels are advised to operate at a safe distance (approximately 1.5 nautical miles) from the area identified.

The cable will be recovered, jointed to the installed cable, and buried during 2016.

Guard vessels

Guard Vessels have been deployed to aid in monitoring the exposed cable and to advise of safe distances locally.
