Notices to Mariners Week 7, 8 & 9

With apologies I have been away on holiday… well actually I am not sorry other than catching up 3 weeks all in one go!……….Roger Gaspar

Permanent/Preliminay and Temporary UKHO

Week 9

1. ENGLAND – East Coast – Depths. Drying heights. – Four reductions of depth/increase of drying heights on the Cork Sands and vicinity. – interesting but not really where peeps would go.
2. ENGLAND – East Coast – Buoy. – A move of a yellow special buoy to the northern perimeter of the Sheringham Wind Farm. – Unexciting.
3. ENGLAND – East Coast – Depths. – One reduction of depth right in the middle of the Medway Approach Channel (where we ought not to be when busy ….. and unlikely to hinder leisure craft).
4. BELGIUM – Depths. – A preliminary notice notifying of 18 reduced depths over the Oostdyck and Middelkerkebank. – Undramatic
5. BELGIUM – Depths. – This ‘permanent’ notice adds four reduced depths to the above preliminary notice. The images include both sets of reduced depths.
6. ENGLAND – South East Coast – Buoyage. – Two temporary special buoys established on the North Sand Head of the Goodwins and easts of the Ramsgate dredged channel.

Week 8

1. ENGLAND – East Coast – Depths. – Four small reductions of depth in the Sunk Inner area of the Sunk Precautionary Area. At over 15m, unlikely to hinder leisure craft.

Week 7

1. ENGLAND – East Coast – Depths. – 7 reductions of depth in the Corton Road (off Lowestoft), and on and around the Holm Sand. The reduction of depth in Corton Road is dramatic and needs to be noted! So much so that I checked the change 3 times!
2. ENGLAND – East Coast – Depths. – Three reductions of depth in the River Thames between Purfleet and Broadness, Grays. All unlikely to hinder leisure craft.
3. ENGLAND – East Coast – Measuring instruments. – Five unmarked seabed and six marked measuring instruments in and around the Blackwater. This is in connection with the research for the new Nuclear Power Station. I would suggest any user of the Blackwater should take note or the unmarked seabed instruments. Tacking across the Blackwater mid-tide is running the risk of hitting one such instrument, another when going through Thirstlet Creek and the stumble. The three on Dengie are, perhaps, safely closer to the shore for people using the Ray Sand (the 1 degree meridian is the best option). But don’t tack down towards the edge of Sales Point (but there has also been warning of an obstn off Sales Point). Frankly, my first reaction is that the unmarked seabed stuff on the edge of the Blackwater is positively dangerous. Perhaps I am wrong.
4. ENGLAND – East Coast – Measuring instruments. Buoyage. – Three marked seabed instruments situated in the environs of Harwich Harbour.

1. Woolwich Reach – Environment Agency – Thames Barrier Closures 2020 – Dates for May through to September in the Temporary List on my usual page.
2. ERITH REACH – MONARCH PIER – SUNKEN PIER AND BARGE REMOVAL – On or after Wednesday 5th February 2020 contractors GPS Marine Limited will be working on behalf of Thames Marine Fuels Limited to recover the sunken pontoon of Monarch Pier which is currently lying between the downriver dolphins. In addition, work will also be carried out to remove a sunken drydock which is laying between the middle and upstream piles of the pier. Work will be carried out from the GPS 3010 spudleg pontoon with the assistance of GPS ALERT and GPS BATTLER. Usual precautions.
3. HALFWAY REACH – DAGENHAM NO.8 JETTY – DREDGING OPERATIONS & JETTY WORKS – On Monday 17th February dredging operations and jetty works will be carried out at Dagenham No. 8 Jetty for approximately 8 weeks.
Dredging operations will be carried out from the deck of the pontoon “TMS SEAVOYAGER” using a deck-mounted excavator and crane. The pontoon will be moored on rise and fall spud legs alongside which dump barges will moor for the removal of excavated material. At the same time as dredging operations are carried out work will take place on the installation of new fendering on No. 8 jetty and the downstream dolphins which will also have new handrails fitted.
The vessel PROSPER will be in attendance throughout the works and will maintain a listening watch on VHF Channel 14. Usual precautions.
4. South Shipwash buoy unlit – southern entrance to Harwich Deep Water Channel – the South Shipwash buoy (51°52.713’N, 001°33.972’E) with light characteristics Q(6)+LFl.15s is temporarily unlit.
The duplicate South Shipwash buoy remains lit and both buoys are reported to be in position.
5. Royal Burnham Yacht Club Pontoon – DAMAGE – the Royal Burnham Yacht Club’s Pontoon in approximate position: 51˚ 37.417’N, 000˚ 49.192’E has been severely damaged by strong winds and is therefore not to be used under any circumstances without permission from the Royal Burnham Yacht Club until further notice.
6. Branklet Lighted Buoy – the Branklet Lighted Buoy in approximate position: 51˚ 36.983’N, 000˚ 52.113’E is back in operation.

8. Port of Wells – dredging
9. River Stour, Sandwich Swing Bridge – due to the overrunning Southern Water road works on the Sandwich Bypass Kent County Council has put the date of the works to Sandwich Swing Bridge to Monday 30th March. This to avoid traffic gridlock in and around Sandwich. The period of the works has been extended by a further week to 8 weeks duration, to accommodate the Easter weekend and the Spring Bank Holiday.
