The Department of Transport has been advised that a geophysical survey, remotely operated vehicle (ROV) diving and an offshore survey of gas pipeline landfalls in Scotland’s Brighouse Bay and Ross Bay, Kirkcudbright and Ireland (Loughshinny and Gormanston) will take place between Tuesday 14 November and the end of December, subject to weather and operational constraints.

Survey works on the Irish Sea gas interconnector will begin in Scottish waters on 14 November before moving into Irish waters on Sunday 19 November.

The survey vessels will conduct a geophysical, ROV and offshore survey of the pipeline landfalls. These shallow water surveys will extend to a depth of approximately 10m below the lowest astronomical tide (LAT) at each location.

The surveys will be conducted by the vessels AMS Panther (callsign 2EHC2) and 4Winds (callsign PCPE) which will work on a 24-hour basis, the former near-shore to some 10m below chart datum and the latter outside that.

During the surveys and ROV diving operations, the vessels will be displaying the relevant day shapes and night lights and will be monitoring VHF Channels 12 and 16.

Due to ROV operations being operated from the vessel, all other passing vessels are requested to leave a wide berth during the operations and operate at minimum speed to reduce vessel wash.

Coordinates and a map of the survey areas as well as contact details can be found in Marine Notice No 75 of 2023, attached below.
