2. ENGLAND - East Coast - Depths. - This is a Preliminary Notice which is part of a series of seven other Preliminary Notices published in the second part of 2024 and one earlier this year. The series has published 36 reductions of depths from Winterton Ness and Kessingland. This Notice is adding four reductions of depth from Hemsby Hole to just north of Great Yarmouth. As such the new reductions should not hinder leisure craft. The notices in in 2025 is 448(P) and 2024 are: 4389(P), 4628(P), 4900(P), 5001(P), 5018(P), 5069(P) and 5165(P). You can access the images for those in the 2024 list.
This notice has one reduction of depth right in the middle between the Newcome Sand PHB and the S. Holm SCB (i.e. the Stanford Channel south entrance). At 3.6m there is significant water for leisure craft but the entrance continues to reduce!
3. BELGIUM - Buoyage. Scientific instruments. - Three yellow special purpose light-buoys, X-Shape topmarks, Fl.Y.5s, marking scientific instruments, have been established west of Oostende harbour.

1. Sea Reach - London Gateway Berth 5 Ground Investigation Works - Commencing on or around 3rd February 2025 marine ground investigation works by Causeway Geotech Ltd will commence as part of DP World London Gateway’s extension project. The works, which are expected to last for six weeks, will be undertaken by Jack-up barge “CAUSEWAY GIANT 1” (24m x 17m) in 13 bore hole locations positioned alongside the berth face of berth 5 (in alignment with berth 4). Workboat “MPV BULLDOG” & “MV SNOOPDOG” will be in attendance.
Exclusion zone of 75 m clearance of planned berth position of a vessel on berth 4 (during manoeuvring, assisting tugs are permitted to be within the 75 m exclusion zone around the barge). Exclusion zone of 100 m from the JUB barge to passing traffic. All vessels involved with the works will maintain a continuous listening watch on VHF Channel 68.
2. Woolwich Reach - Environment Agency Thames Barrier Closures Commencing 1st May 2025 - The Thames Flood Barrier will be closed once a month for test purposes, in accordance with a programme issued for a period of six months, commencing 07 November 2024. Listed below are the times between which the Thames Barrier will be closed to navigation for test purposes.During these periods’ navigation in the Thames Barrier Control Zone, between Margaretness and Blackwall Point, will be restricted and any movements in this area will require permission from London VTS.
PROGRAMME OF CLOSURES - All times are approximate.
May Monday 19th 11:00 to 13:40
June Monday 16th 10:30 to 13:00

The closures will be confirmed and promulgated by London VTS from 24 hours in advance of the operation by VHF radio on routine river broadcasts. From the start of each closing procedure until completion of the opening procedure vessels will be prohibited from transiting the Thames Barrier. Most closures are for approximately 2½ hours over the respective low waters. No vessel is to pass Margaretness inward bound or Blackwall Point outward bound once a Thames Barrier closure has commenced unless authorised by London VTS. GATE CLOSURES
In addition to the full Thames Barrier closures there will be frequent closures of individual gates for maintenance and training purposes, subject to a programme issued by the Environment Agency. The closure of individual gates will change the spans available for navigation.
Information regarding these gate closures will be promulgated by London VTS on VHF Channel 14 routine river broadcasts. During each full Thames Barrier or individual gate closure(s), illuminated red crosses will be displayed on both sides of the gate(s) indicating that the gate(s) are closed to navigation
