As previously reported on, Greenlink Interconnector Ltd is proposing to develop an electricity interconnector to allow for offshore cable installation and burial at a later stage.

A pre-lay grapnel run (PLGR) will be performed along the planned interconnector route to ensure clearance of debris from this Friday 15 March to next Tuesday 19 March, subject to weather and operational constraints.

During the PLGR, a grapnel shall be deployed on the planned cable route and dragged over the seabed. Whenever an increase in tension is recorded or in any case at five-kilometre intervals, the grapnel will be recovered cleaned and inspected. Afterwards, the grapnel will be redeployed to the seabed. The operation will be repeated until the complete route of about 80km has been finished.

The PLGR operations will take place along the planned interconnector route from the landfall location at Baginbun Beach towards the middle of the interconnector route.

Operations will be performed by the Forth Warrior (callsign 2JHR8). The vessel will have the PLGR grapnel deployed on the bow roller.

As the vessel will be restricted in its ability to maneuver, all other vessels operating within this area are requested to keep a wide berth and pass at minimum speed to reduce vessel wash. The vessel will be listening to VHF Channel 16 and can set any other channel as required.

Coordinates and a map of the work area as well as contact details can be found in Marine Notice No 15 of 2024, available to read or download HERE.
