UKHO Permanent/Temporary/Preliminary
1. ENGLAND - East Coast - Depths. - Seven reductions of depth in and around the NW Hom SHB in Corton Road (Lowestoft to Great Yarmouth). Depths are sufficient for leisure craft but two of the reductions are quite significant (e.g. 7.3m down to 3.1m).
2. ENGLAND - East Coast - NM Blocks. - We had a local NTM from Fenland last year of survey work. The UKHO is now issuing chart blocks covering the Wash approaches to Wisbech, one for the SNC and one for the SCC.

1. River Thames - Sea Reach - Oikos Jetty No.1: Dredging Operations - on or about 9th February 2026, contractors instructed by Oikos Storage Ltd. will commence dredging operations in the approaches to Oikos No. 1 Jetty. The general location of the works is indicated by the red box on the chartlet.
These dredging operations will be carried out by the Water Injection Dredging method and will be conducted during ebb tides only. The area to be dredged comprises the Oikos No. 1 Jetty berth box as well as the rear, clearance channel and the approach / transit area to the berth. The dredging is planned to be completed no later than 19thth February 2026. Requirements to proceed with caution or at slow speed will be made in accordance with the procedure set out in the Port of London Authority’s Port Information Guide, under ‘Speed Reductions’, with the International Code Flags ‘Romeo Yankee’ displayed. The display of these signals will be in addition to any lights or shapes required under local regulations and the International Regulations for Preventing Collisions at Sea. Further details will be broadcast as appropriate by London VTS on VHF Channel 68.
2. River Thames - Northfleet Hope - Gravesend Reach - Port of Tilbury: Dredging Operations - on or about 07th February 2026, contractors instructed by Port of Tilbury London Ltd will commence dredging operations at Tilbury Lock Entrance, Tilbury Grain Terminal Main Berth and Tilbury 2 CMAT. The general location of the dredging is indicated by the red boxes on the chartlets. These dredging operations will be carried out by the water injection dredging method by vessel MAAS and will be conducted during ebb tides only. An alternate dredging vessel may be substituted if necessary; in this case, details will be broadcast by London VTS. The areas to be dredged includes Tilbury Lock bellmouth / entrance and the respective berth boxes of the other locations. The dredging is expected to be complete no later than 01st March 2026. Requirements to proceed with caution or at slow speed will be made in accordance with the procedures set out in the Port of London Authority’s Port Information Guide, under ‘Speed Reductions’ with the International Code Flags ‘Romeo Yankee’ displayed. The display of these signals will be in addition to any lights or shapes required under local regulations and the International Regulations for Preventing Collisions at Sea. Further details will be broadcast as appropriate by London VTS on VHF Channel 68.
3. River Thames - Sea Reach - London Gateway Port - Berth 5: Quay Wall Extention - Piling Operations - On or around 3rd February 2026, contractors working for London Gateway Port will move on to the next phase of piling works at Berth 5, with marine piling operations due to commence soon after.
With the 430 m Berth 5 extension now complete, piling works will focus on a further 75 m extension into the area that will form Berth 6. This activity will construct a new section of retaining wall to support the continued westward development of the port. A bubble curtain will be deployed to mitigate noise from the piling operations. The works will utilise the Neptune 585 Eurobarge, a 75 m x 25 m floating barge equipped with a 750 t crawler crane to support lifting operations. A second flat‑top delivery barge, the Neptune NP674 Barge (60 m x 20 m), will be used for the storage and delivery of materials alongside the crane barge. All barge movements will be carried out by the multi‑cat vessel Felix or similar. A safety boat, the WSB Resolute, will also be in attendance. A 75 m exclusion zone is to be maintained from vessels manoeuvring on and off Berth 4 by delivery and support barges. During manoeuvring, assisting tugs are permitted to enter the 75 m exclusion zone. Once a vessel is suitably moored on Berth 4, delivery and support barges may operate within 75 m of the vessel’s final berthed position if required. Works are expected to continue until August 2026. All vessels involved in the works will maintain a continuous listening watch on VHF Channel 68. For the latest information, contact London VTS on VHF Channel 68.
4. Surveyed Depths – Harwich Harbour - latest hydrographic surveys showing depths in Harwich Harbour which are published as follows: Charts & Surveys - Harwich Haven Authority The controlling depth for deep draught vessels navigating within the harbour area should currently be taken as 15.1m below chart datum, plus height of tide. Significant depths below chart datum (not including inside berth boxes) are:
• 15.1m - spot soundings between the North West Beach Buoy and Grisle Buoy
• 15.3m - spot soundings between the Grisle Buoy and Shotley Spit Buoy
• 15.2m - spot soundings between the Shotley Spit Buoy and Babergh Buoy
Contact Harwich VTS or Haven Pilots for further information regarding tidal windows.
5. Harwich Harbour - Dredging Operations – Jean T – update 1- tug Jean T (Callsign: MVS06) will be undertaking plough dredging operations at Harwich from around 09 February until 22 February 2026, in the following locations (Latest dredger movements can be obtained from Harwich VTS on VHF Channel 71.):
