Western HVDC Link: Survey Works of Cable Installation in Liverpool Bay, Irish Sea, North Channel and Firth of Clyde
Friday 3 March 2017
Mariners are advised that survey works for the installed cable sections on the Western HVDC Link route are due to be start in early March 2017. Information about the nature and location of the survey work is provided in a Notice to Mariners that can be downloaded here and which is summarised below.
Survey works
Survey work in Liverpool Bay, the Irish Sea, the North Channel and the mouth of the Firth of Clyde is due to be conducted by the vessel Normand Pacific. The survey will consist of a visual and instrumental survey of the installed cable route using a Remotely Operated underwater Vehicle (ROV) deployed from the vessel.
The location of the survey work is illustrated in the Notice to Mariners, along with a list of all of the survey locations. This notice can be downloaded here, .
Vessel details
Details of the vessel involved in these operations, along with its present location can be found on MarineTraffic.com via the link below:-
Normand Pacific: Multi Purpose Offshore Vessel | Call sign LAXI7
The vessel will be monitoring VHF Channel 16 throughout the operation.
The vessel involved in this work will be restricted in its ability to manoeuvre and other vessels are reminded to navigate with caution in its vicinity and pay strict attention to instructions issued to them by navigation authorities.
Guard vessels
Guard vessels have been stationed along the cable route during installation and burial to ensure the safety of marine users. They will remain in position until cable protection operations are completed to advise mariners of the location of exposed cable.
In areas where the cable crosses other cables and pipelines that are in service, the guard vessels will remain on station until cable protection has been completed in these locations (either through concrete mattressing or rock placement).
