Deep Green Project: Removal of MGS Buoy – July 2021

Mariners are advised that Minesto UK  Ltd have permanently removed the MGS buoy from the  “Deep Green” area in the Holyhead Deep off the coast of Anglesey, North Wales.  Details are provided in a Notice to Mariners that can be downloaded here and which is summarised below.

Location of MGS buoy

The MGS buoy was located off the coast of Anglesey, approximately 6km west of South Stack to the inner harbour in the Port of Holyhead at position 53° 17′ 47.739″ N 004° 47′ 45.493″W.

Operational area & Safety Zone

The charted “Operational Area” remains in force.  This is shown in a map on the Notice to Mariners (here).  There is equipment on the seabed in this area.

The safety zone of 500m on the sea surface which was established on the MGS buoy at the location above is now lifted.

A safety zone of 500m on the sea surface will be reinforced around any project vessels when offshore operations are carried out, and all vessels are requested to give a wide berth to any vessels working on site.

Details about these changes and the MGS buoy can be found in the Local Notice to Mariners which can be downloaded here.
