2. River Thames - Blackwall Reach - Brunswick Wharf Exclusion Zone - Thiis Notice supersedes and replaces M70-25, which is hereby cancelled. A 60-meter exclusion zone is currently in effect adjacent to Brunswick Wharf in Blackwall Reach. This restriction is expected to remain in place for approximately three months. The exclusion zone has been established due to structural issues in a shoreside building, which pose a potential risk to vessels navigating in the vicinity. The zone extends 60 meters from the river wall across the frontage of the affected building, as illustrated. No vessels are permitted to enter the marked exclusion zone.

Shotley Spit Buoy – Out of Assigned Position – Update 1 - the Shotley Spit Buoy has been temporarily relocated to the following position: • 51°57.12’N, 001°17.39’E (Approximately 50 metres from its original position on a bearing of 251°). A further notice will be issued once the buoy has been returned to its assigned position.
4. Surveyed Depths – Harwich Harbour – Update 12 - the latest hydrographic surveys showing depths in Harwich Harbour.

All dive ops. will be carried from the support vessel KM Otter who will maintain a listening watch on VHF Channel 74 whilst on site. All vessels passing Thamesport should navigate with caution, reduce speed and wash and maintain a listening watch on VHF Channel 74 at all times, vessels manoeuvring onto and off of Thamesport should check the status of diving operations prior to arrival/departure.
7. East Anglia Wind Farm - further to the thread last week with activities off Bawdsey there is a long NtM from the Wind Farm and I have attached relevant details of operations from the weekly bulletin. It is long so I cannot post it here but you can read it at the Local List on the web page quoted above. The short message is: Nearshore works (off Bawdsey) are continuing and the primary vessel - the NKT Victoria - now has a 1000m exclusion zone. There are numerous vessels working on the cable route and at the wind farm.
8. London Array Wind Farm - Drone Operations -
All mariners are advised that the Work Vessel Spectrum 1 will be onsite from 11/07/2025 undertaking low level Drone Survey Operations. Survey works will be carried out between G15 and H13. (That's well clear of Foulger's Gat). Planned Locations and Restricted Access Zones A 750m radius restricted zone will be in place, centred on the Spectrum 1 whilst conducting drone operations with in the wind farm .If access is required to this zone for non-project vessel traffic, authorisation must be requested from the vessel. The area marked red on the map indicates the flight route planned for low level drone survey,
That's it.
