Offshore Cables

Approximately 170km of the Greenlink cable route will be laid offshore. The final routes will be selected following a detailed assessment of the marine environment and technical challenges.

The cables will predominantly be buried in the seabed however where the geology or marine environment does not lend itself to this a cable may be laid on the seabed with protection added. Protection could be in the form of concrete mattress or rock dumping on top of the cable.
