#MARINE WARNING - The latest Marine Notice from the DTTAS advises all seafarers in the Irish Sea between north Dublin and north Wales to give a wide berth to the hydrographic and oceanographic survey operation in the area this week.

The SV Bibby Tethra (callsign 2EGF8) commenced survey operations yesterday (Monday 16 January) from offshore at North Beach in Rush to approximately 16 miles offshore north of Anglesey. The survey is scheduled for seven days, subject to weather delays.

The vessel will operate on a 24-hour basis, displaying appropriate day shapes and lights during survey operations, and will transmit an AIS signal. The vessel will be keeping a listening watch on VHF Channel 16 at all times during the operations.

Survey operations will involve towing survey equipment up to 100m astern of the vessel along pre-defined survey lines, which will restrict the vessel’s ability to manoeuvre.

Details of the survey area are included in a PDF of Marine Notice No 2 of 2012, which is available to read or download HERE.
