UKHO Permanent/Temporary/Preliminary

1. ENGLAND – East Coast – Depths. – 5 reductions of depth in the Mouse and Mouse Channel (the inner part of the Barrow Deep). The image includes two reductions of depth from NtM 3533 of 2020. No problems except cutting across the tail of the SW Barrow sand.
2. NETHERLANDS – Explosive dumping ground. – A new explosives dump has been established on the on the edge of the offshore bank Deurloo off the Dutch Walcheren coast. This is surprisingly close to the inner channel, the buoyed ‘Oostgat’.
3. ENGLAND – East Coast – Depths. – Continuing reports of changes in and around the banks off Great Yarmouth and Lowestoft. This notice revises 3 depths in the Holm Channel off Great Yarmouth. The image includes new depths advised in NtM 716, 2558 and 5960 of 2020. Not really hindering leisure craft.

Local – Quiet in the ‘Industrial Ports’

1. Port of Ramsgate – PORT LEAD LIGHTS- Mariners are advised that the Ramsgate Port Lead Light units have failed. Work to reinstate is underway. Mariners are requested to seek advice from Port Control on Ch.14 before entering or departing the Royal Harbour.
2. Port of Ramsgate – As usual they have ‘brought forward’ the usual selection of standing local notices – Notices remaining, Usual Port Signals, Communication, Reporting Point and General – Oil pollution, excess speed (nuffin over 5 kts) and Leisure Craft calling and permissions. There is a link for full details in the Local List on the usual web page: Notices to Mariners
3. Port of Wells – dredging
4. Port and Haven of Sandwich – Swing Bridge – 
A road closure is planned for Friday 29 January 2021 for routine maintenance to enable a new gearbox spline to be replaced on the swing bridge. This particular component had not been available last year and has been especially commissioned. These works are required to maintain operation of the swing bridge. The road closure is for one day only during the day. Vehicles will be routed around the signed diversion route. Restricted access for pedestrians will be maintained across the bridge except for when the operation of the swing bridge is tested. During these events there will be no access across the bridge for periods of about one hour. It is proposed to raise the bridge deck and prop it on the abutments to provide safe working space to install the new components. The swing bridge will not be able to operate during this period that will probably extend into the late afternoon. The deck will then be swung open (to navigation) several times for testing and inspection. Given the uncertainty of timings navigation will be suspended for the day.
5. Havengore Bridge: Update 22.01.21 – Havengore Bridge remains closed to marine traffic. The engineer visit expected this week was unfortunately postponed and has been rescheduled for next Wednesday 27 January when further investigation and repairs are planned. We will issue the next update in the latter part of next week. We apologise for any inconvenience. Nicki Uden – Community Liaison Officer, SHOEBURYNESS RANGE
6. London Array Offshore Wind Farm – 
the charted wave buoys within London Array Windfarm have been permanently removed. Details can be found in the Local list but all were in-field in the Farm and so out of the way.
