1. BELGIUM - Wind farm. Restricted area. Wind turbines. - The Rentel wind farm has been established, within a restricted area, entry prohibited, bounded by charted limits and limits. This notice showing the limits of the Rental Wind Farm which is between the Northwind and Thorntonbank Wind Farms. Being in Belgium waters, the area is prohibited to be entered. The notice also shows the SPS (Significant Peripheral Structure) and IPS (Intermediate Peripheral Structures) turbines (i.e. the turbines marked by light). Other turbines are not included. I have drawn up an image should the limits, positions of turbines and the SPS and IPS markings. See: http://www.crossingthethamesestuary.com/page9.html
2. ENGLAND - East Coast - Depths. - Two new reduced depths on the east edge of the North Caister Shoal. The image shows those two positions. Note that there a dots marking previous NtM reduced depths which relate to NtMs 1364 and 2380(P) this year. A supplementary image shows those additional reductions for your convenience. See the same page for the images;
3. ENGLAND - East Coast - Fouls. Buoyage. - This is a repeat of the local Kings Lynn Conservancy Board NtM No 26 of 2018 in week 44, thereby incorporating the changes in UKHO charts. Two new danger buoys in the Wash. Usual image available;
4. ENGLAND - East Coast - Depths. - Continuation of the changes on the Suffolk/Norfolk sands - One reduction of depth on the Holm Sand off Lowestoft.
5. ENGLAND - East Coast - NM Blocks. - This notice provides two UKHO blocks revising the Chart Sources, particularly for the North Edinburgh, Princes and Knock John Channels. It will be interesting to see the next edition of Chart 1607 to see what the North Edinburgh Channel looks like. I recall the dredging of the Princes Channel used the Edinburgh for some of the disposal;
6. ENGLAND - East Coast - Wreck. - This wreck was notified in NtM 4384 as at 27m. This is now changed to 39m. The wreck is south of the Greater Gabbard Wind Farm.

1. FLOODGATE REPLACEMENT WORKS GRAVESEND CANAL BASIN - Starting on 12th November 2018 in-channel flood gate replacement works will commence on the lock for the Gravesend Canal Basin. The majority of the works will take place at low tide with a temporary cofferdam being installed. For this reasons a ‘Proceed with Caution’ will be issued by London VTS on VHF Channel 68 asking passing vessels to minimise their wash. Navigation through the lock will be managed by the on-site team on an ad-hoc basis. Works are expected to last for approximately 12 weeks.
2. LIMEHOUSE REACH - TEMPORARY BARGE MOORING - on or about 14 November 2018 contractors working on behalf of the Tideway Tunnel Project will lay an additional temporary barge mooring off Deptford Wharf. The PLA vessel LONDON TITAN will lay a barge mooring in a position south of the channel as indicated in red on the chartlet in the Temporary List on the above page. The barge mooring will be laid as a tier marked by unlit Admiralty class buoys at each end and identified as Deptford Strand Barge Moorings. It is anticipated this tier will be in place for the duration of the Tideway Tunnel workings. The installation works will be supported by DRIFTWOOD and other PLA craft. Vessels are requested to be mindful of the nature of the works, their wash when passing the works and to pass at a safe distance.
