Local

1. RIVER MEDWAY – SHEERNESS HARBOUR – GARRISON POINT RADAR FAILURE – due to technical issues the RADAR at Garrison Point in the following approximate position has failed and hence is not rotating. Garrison Point Radar 51 26.82 N – 000 44.65 E
Options to repair or replace the equipment are already being explored and full restoration of service is anticipated soon. The RADAR mounted on the Lappel Bank mast continues to provide full coverage to the seaward port limits.
2. RIVER MEDWAY – SALTPAN REACH – BP IOG. No1 – Berth Inspections & Associated Work – work is due to take place at BP Terminal Isle of Grain Jetty No.1 between 24/02/2020 and 28/02/2020. The work will involve inspections of the berth structure and installation of cathodic protection equipment. All activities will be conducted from the vessel ‘Chatham Albatross’ who will be monitoring VHF Channel 74 at all times. Operatives will be working on the waterline, therefore, all passing vessels are requested to proceed with caution and minimise their wash.
3. LOWESTOFT – OUTER HARBOUR – BOREHOLE OPERATIONS – borehole operations are scheduled for the outer harbour. A jackup barge will be mobilised from North Quay 6 from Monday 24th February 2020. The tug ‘Jumbo’ will be used to move the Jack – up to each borehole location. Two boreholes will be drilled on the north side of Waveney dock adjacent to the Hamilton peninsula (No. 1 and 2). Two boreholes will be drilled along the eastern edge of the navigational channel up to Waveney dock (No. 3 and 4).
Three boreholes will be drilled around the south west arm of the Trawl dock / Sladdens (No. 5, 6 and 7). The boreholes will be drilled by a jack up barge ‘Haven Seajack 2’ 18.3 x 18.3 m. One borehole will be drilled at a time and the jack up will start with Borehole No. 1, the other boreholes may not be drilled in a consecutive order.
4. Port of Wells – dredging
5. Port and Haven of Sandwich – Environment Agency emergency works at Pillory Gate Wharf. Mariners are advised that emergency works to the Sandwich flood defence scheme at Pillory Gate Wharf (Highway Marine) will start during week commencing 17th February 2020. A jack up barge will be in attendance along with a safety vessel. Vessels should pass at slow speed and be prepared to take instructions from the contractors. River width will necessarily be limited. Large craft going downstream should do so against an incoming tide. Should they be unable to pass due to insufficient room they must moor to the south side of the river’s ‘Bridge waiting berth’ to await availability of sufficient river width, which may be a week or more. Vessels going upstream should likewise assess the available river width BEFORE transiting the bridge. If there is insufficient space vessels should make fast to the Quay to await a favourable moment, which may be a week or so. Consequent of the above masters of large vessels are strongly advised to await removal of the barge.
6. Port of Ramsgate – several notices –
OUTER WEST MARINA BREAKWATER PONTOON – Mariners are advised that the southernmost pontoon section of approximately 10m in length has been removed for maintenance. The navigational lights (2 vertical greens) remain on the southernmost pile. Mariners should not transit between the remaining breakwater pontoons and the southernmost pile.

RAMSGATE NO. 5 BUOY – No. 5 buoy is currently off station (by radar observations) by 120 metres, bearing 037.5 T (51.19.619N – 001.25.977E) from its charted position 51.19.557N – 001.25.918E).

RAMSGATE HARBOUR – the OUTER WEST MARINA BREAKWATER PONTOON is currently not available for berthing

WEST QUERN BUOY – (51.18.98N – 001.25.39E)- the West Quern buoy is currently missing from its charted position.

That’s it.
