UKHO Permanent/Preliminary or Temporary
Only two - and uninteresting:
1. ENGLAND - East Coast - Depths. (strange title this week!) - Two reduced depths in the Thames: the first right by the Broadness port hand buoy, the second just east of the QEII bridge. Neither likely to hinder leisure craft.
2. ENGLAND - South East Coast - Wrecks. Depths. - Change of depths on four wrecks east of Kent. All at safe depth for passage by leisure craft.;
1. THAMES BARRIER DREDGING OPERATIONS - On or about Monday 25th June 2018 for approximately 1 week, conducting dredging operations in FOXTROT span of the Thames Barrier. The dredging will be undertaken from a flat top pontoon positioned alongside pier 5 with a hopper barge alongside to take the dredged material. During the dredging operations, FOXTROT span will be in the maintenance position.
2..Rivers Crouch & Roach - CHA Annual Buoy Maintenance - is due to commence on Monday 25th June 2018. The work will be carried out from the vessel 'JUMBO' which will keep a listening watch on VHF channel 11/16. Requested to give a wide berth and pass at a safe speed so as not to create excessive wash whilst the vessel is alongside the navigation marks.
The work is expected to take approximately several weeks.
3. LOWESTOFT OUTER HARBOUR – BRIDGE CHANNEL QUAY WALL MAINTENANCE/REPAIR - schedule to commence on Wednesday 20th June, to repair suspended quay support structures and fender sections on the South side of the Bridge Channel, just East of the Bascule Bridge. The works will be undertaken from Vessel 'Flying Hart' with support craft 'Cargo of Dreams', berthed alongside the areas. All craft will monitor VHF Ch.14. Vessels wishing to transit the area should contact Port Control to obtain information and advice on works activities. Vessels should only pass the works sites once permission has been granted, should afford as wide a berth as is safe and practical, and pass at slow speed to reduce vessel wash. Works are expected to take approx. two weeks to complete.
4. Ramsgate - Mitre Gates and Lifting Bridge Works - Mitre Gates will be reinstated by a floating crane on Wednesday 27 June. On Friday 29 June the Flap Gate will be removed to be overhauled. During these periods, it will not be possible to transit between the Royal Harbour and the Inner Basin. Both operations are subject to weather, further information can be sought from Ramsgate Port Control on VHF Ch. 14. The crane barge 'Skyline 21' will be listening on VHF Ch. 14 - Mariners are asked reduce their speed to create minimum wash when passing the work area.
