Further to previous installation works on the Havhingsten fibre optic telecommunication cable system in the Irish Sea, post-lay inspection and burial (PLIB) of the cable is planned to begin later this week.
Works outside Irish and Isle of Man territorial waters are will start on Friday 14 January and continue until next Thursday 20 January, subject to weather.
It is advised that extra care is taken when vessels are operating near this area and that no vessel should trawl within 500m.
Installation will be via industry-standard burial tools including water jetting with remote operated vehicle (ROV). The target cable burial depth is 1.5m below seabed level in the region.
There will be two locations where PLIB will be performed: at Final Splice (FS) location outside Irish territorial waters, and at Branching Unit (BU) location outside of Isle of Man territorial waters.
The operations will be conducted by the cable installation vessel CS Ile d’Aix (callsign FICI) which will be working on a 24-hour basis, and will display appropriate day shapes and lights during reduced visibility and night operations.
All vessels operating within this area are requested to keep their distance and pass at minimum speed to reduce vessel wash.
