Hunterston-Kintyre Cable: Rock placement update, 19th September 2015

This notice provides an update on progress with rock placement work on the Hunterston-Kintyre undersea cable in the Firth of Clyde.

Rock placement work started on the 9th September with the vessels Seahorse and Rockpiper working close to the Kintyre and Hunterston cable landfalls.  The Rockpiper has been working on the Hunterston landfall and nearby anchoring zone.

The Seahorse started work at Kintyre landfall and progressed eastwards at locations along the cable route.  The Seahorse left the Clyde earlier this week to collect more rock and is due to return on site on the 21st September 2015.  Seahorse is due to complete works on the cable on the 22nd September 2015, weather permitting.

A series of charts showing the location and extent of each area of rock protection, as well as the indicative timetable for works can be downloaded here.

A Notice to Mariners has been issued for this work by Peelports.  This can be downloaded here.
