All work will be completed from the surface and across the mudflats during multiple low water periods, NO diving will be undertaken. Please be advised that during survey operations the vessel will be restricted in it’s ability to manoeuvre and other vessels are requested to be mindful of the nature of the works, reduce their wash when passing, maintain an appropriate safe distance and monitor VHF Channel 74 at all times. Admiralty Charts : 1835 & 2482 refer. Further information may be obtained from Medway VTS on VHF Channel 74, call sign “Medway VTS” or telephone 0151 949 6148 or 0151 949 6650 (Recorded Lines).
