Partrac Ltd intend to deploy three Metocean buoys at the Dublin Array offshore wind farm in a one-day operation some time between this Wednesday 9 and Wednesday 23 June, weather permitting.

One floating lidar buoy and two wave buoys will be deployed by the AMS Retriever (callsign MEHI8) which will be displaying all appropriate lights and shapes.

The floating lidar buoy has a square footprint with an area of 4m2 and a height of some 4m above the water line. It is yellow in colour and has a St Andrew’s cross on top.

The wave buoys are spherical in shape with a diameter of around 1.1m. When deployed, the wave buoys appear clear with a yellow hull.

Both the floating lidar buoy and the wave buoys have a yellow light which emits five flashes every 20 seconds. The light is visible for up to three nautical miles.

The floating lidar buoy will be deployed for a period of four to eight weeks. It will then be moved to a permanent position in the south end of Dublin Array where it will be deployed for 18 months. The wave buoys will be deployed for a period of 12 months.

The floating lidar buoy will be towed approximately 30m astern of the AMS Retriever at a maximum speed of four knots.

As such, the vessel will be restricted in its ability to manoeuvre so all other boats operating in proximity are requested to keep their distance, maintaining a safety zone around the deployment vessel and pass at minimum speed to reduce vessel wash.

Details of the buoy locations are included in Marine Notice No 37 of 2021 which can be downloaded below.
