The Department of Transport has been advised by Fuinneamh Sceirde Teoranta (FST) that a metocean survey comprising one large metocean buoy and two trawl resistant seabed frames will be deployed at the site of the proposed Sceirde Rocks Windfarm in north Galway Bay off southwestern Connemara.

The deployment will take place between this Saturday 29 July and the end of August, subject to weather and operational constraints.

Equipment will remain in place for up to 24 months, and periodic service visits to the equipment will take place throughout the survey period.

The metocean buoy has a hull diameter of 3.6m and focal height of 4m. The buoy is yellow in colour and displays a St Andrew’s Cross. It is mounted with one automatic identification system (AIS) unit (161.975 MHz) and one navigation light (sequence Fl(5) 20s, range 3nm).

The buoy is double moored using a mooring chain and sinker blocks. The anchor and sinkers will be placed approximately 200m away from the metocean buoy. The mooring line will consist of approximately 200m of chain per leg, partially suspended in the water column and partially laying on the seabed.

The trawl-resistant seabed frames are approximately one square metre each and will be unmarked.

This metocean equipment will be deployed from the ILV Granuaile (callsign EIPT), which will operate on a 24-hour basis. Throughout operations, the vessel will display the appropriate lights and shapes as required under the COLREGS Rule 27 (b).

During operations, the vessel will be restricted in its ability to manoeuvre. Vessels are requested to leave a wide berth during the deployment operations.

Radio transmissions will be conducted with other seafarers to notify them of the operations. All vessels will monitor VHF Channel 16 for emergency communications with other seafarers and then mutually agree another channel to switch to for further discussion as needed.

Coordinates and a map of the deployment area as well as contact details can be found in Marine Notice No 46 of 2023, attached below.

The construction of a sustainable transport bridge at the Port of Waterford between the North and South Quays was expected to begin on Monday 24 July.

These works will be ongoing until the end of 2024, subject to weather and operational constraints.

Three barges will be in operation during the works: the ACN5, the Ardon and the Skerchi — the latter of which will be relocated at various times during construction. The barges will exhibit a sign that reads “Warning – Marine Works – KEEP AWAY”.

Barge masters will maintain a continuous VHF watch on Channels 6 and 16. A safety boat will be always in attendance with the barges during construction works.

All vessels approaching the area of operations should communicate with the barges on VHF Channel 6 and proceed with caution, giving them a wide berth where possible.

The channel will remain navigable between Pier C and Pier D but temporary navigation lights will be established. The existing red lights on the east and west ends of the clock tower pontoon will be replaced by yellow lights.

In addition, to facilitate the works the pontoon at the clock tower will be partially dismantled and is no longer available for use.

Coordinates and a map of the work area as well as contact details can be found in Marine Notice No 51 of 2023, attached below.
