All mariners are advised that a new yellow conical special mark, with a 10 knot speed advisory, has been laid to seaward of the Beacons Pontoon in Conwy Harbour.  The mark position is Lat. 053° 17.753’ North, Long 003° 50.422’ West.  The mark is lit with a yellow lantern, flash characteristic Fl Y 10s.

The 10 knot speed limit is a maximum and certain vessel hull types can still generate an excessive wash at speeds of 10 knots or less.  It is a matter of both good seamanship and safety to ensure excessive wakes are avoided so as not to potentially endanger other harbour users.

The Awel y Môr Offshore Wind Farm is an extension of the Gwynt y Môr Offshore Wind Farm originally developed by RWE in the Irish Sea. The proposed site has a total area of 106km2 with a capacity of approximately 576 MW. The development will include offshore transmission assets, with the export cable route likely to reach landfall on the North Wales coast to allow a grid connection at Bodelwyddan in Denbighshire.

Fugro will undertake a geotechnical site investigation to characterise the Awel y Môr Offshore Wind Farm extension areas. This survey work is detailed in the attached document.
