This is a ‘tidying’ process linked to last week’s Notice 4087(P) notifying the change for the TSS border position.
To improve the safety of navigation in the Approaches to the Thames Estuary, the International Maritime Organization
(IMO) has approved the modification of the Long Sand Head two-way route and the SUNK Inner Precautionary Area in the
existing Traffic Separation Scheme .In the SUNK area and in the Northern approaches to the Thames Estuary.. These changes will be implemented at 0000hrs UTC on 1 January 2018.
The limits of the two-way route and Precautionary Area are to be extended northwards to route traffic away from the shallow banks of Long Sand Head. These banks are surveyed and monitored on a regular basis and have been found to be migrating north-eastwards.
The details of the amended scheme are shown in the accompanying diagram.
These amendments will be included in a New Edition of Chart 2692 to be published November 2017. This chart will be published with a cautionary note advising mariners that the existing chart, which will be given an .X. prefix, should be retained and used until 0000hrs UTC on 1 January 2018. Charts 1975, 1183, 1610, 1406 and 8157 will be updated by Notice to Mariners. All ENCs affected will be updated at 0000hrs on 1 January 2018.

Notice 3843 refers
This NtM is a consequence of my survey in June. The result of the NtM suggests the swatchway is very difficult. This is because the UKHO policy is only to publish NtM showing reductions of depth and not to include increases of depth in the NtM, attending to that in the next edition of the chart. The important issue of the NtM is to show the movement of the SW Knoll towards the north-east.
I have not included the contour changes in the image, one because it is based on the Imray chart which has different contours to the UKHO, second because I recommend you go to the better scale of my chartlet: there is a good swatchway still there.

Further information regarding the Sunk to Sea Reach buoyage changes.
Note that CTTE has added this latest material to its PDF download which can be accessed here:
Notice 4255(P)/13 ENGLAND - East Coast - Thames Estuary - Sunk, Black Deep, Knock John Channel, Oaze Deep, Yantlet Channel and Sea Reach - Deep water route. Buoyage.
1. As part of the recent dredging campaign for the London Gateway Project and the deepening of channels between the Sunk (51° 51´·70N., 1° 38´·77E.) and Sea Reach (51° 29´·70N., 0° 29´·70E.), significant changes affecting deep draught vessels will occur on the 1 October 2013.
2. The following is a list of the major changes that will happen on that date (please refer to the three diagrams opposite):
a. Within the Sunk Inner Precautionary Area, the Sunk Deep Water Route will be moved approximately 250 metres to the north west so that it runs parallel to the old route. The new route will be marked by the Sunk Inner Buoy which was moved earlier in August. A new buoy is to be laid to mark the wreck of the Dynamo – see London Gateway Project, changes to
ships routeing – Figure 1.
b. In the vicinity of the Sunk Head, the Sunk Deep Water Route will lead into a new deepened channel approximately 300
metres wide and 5000 metres long. A new special marker buoy (SHM) will mark the junction of the Trinity Deep Water
Route to this new channel – see London Gateway Project, changes to ships routeing – Figure 1.
c. In the Black Deep and Fisherman’s Gat Precautionary Area, a new Deep Water Route and deepened channel will be established marked by special marker buoys – see London Gateway Project, changes to ships routeing – Figure 2.
d. In the Knock John Channel, all the buoyage is to be repositioned to mark a slightly amended 300 metres wide deepened channel – see London Gateway Project, changes to ships routeing – Figure 2.
e. In the Oaze Precautionary Area, the Deep Water Route is to be moved south of its current charted position with buoyage repositioned to mark the channel and special marker buoys inserted to mark significant wrecks – see London Gateway Project, changes to ships routeing – Figure 3.
f. The Yantlet Channel will be extended by 3000 metres east south east to link in with the Oaze Deep Water Route near the West Oaze buoy – see London Gateway Project, changes to ships routeing – Figure 3.
g. The Oaze Precautionary Area is to be extended northward by approximately 500 metres in the western part of the Warp area – see London Gateway Project, changes to ships routeing – Figure 3.
3. Mariners are advised that these measures have been put in place specifically for deep draught vessels. Where smaller vessels have sufficient sea room to navigate safely away from the Deep Water Route they are encouraged to do so.
4. For further information mariners should refer to the Port of London Authority.
5. These changes will be included on New Editions of charts 1183, 1185, 1186, 1606, 1607, 1609, 1975 and 2692 to be published in November 2013. Charts 2484 and 2052 will be updated by Notices to Mariners. Those New Editions that cover the Sea Reach area will show the layout of the new London Gateway Container Port. For details of changes to buoyage in Sea Reach please refer to Notice 3514(P)/13. (In Week 33)

This is one of the first changes as notified in Week 33 vide Trinity House notice 15 of 2013 (see that entry for the CTTE PDF on all the changes to the Sea Reach and Black Deep.)
This is a relatively small move in the Sunk Inner Light Float.
The second part of the notice deals with the deletion of the symbol and legend for unexploded ordnance which is not shown on Imray charts (nor on my editions of UKHO charts)

This notice is a Trinity House Notice at present (No 18 of 2013). This notice combines with PLA Notice to Mariners No 14 of 2013 (shown in these pages last week) and two earlier notices to illustrate all the changes that will occur this year in preparation for the commissioning of the London Gateway.
This notice from Trinity House lists the changes that will be made in October, 2013 and affects many charts.
In order to provide readers with simple, clear and useful information, CTTE is publishing a PDF providing a comprehensive list of all the changes occurring during August under the PLA notice and in October under the Trinity House notice. The PDF includes three images illustrating the buoyage as it will be once concluded in October.
The RYA have made enquiries and there is no intention to bring in any restrictions for leisure craft but of course normal Regulations will apply in the Sea Reach to Black Deep channels where large container ships will be constrained by the draught.
Now amended by PLA NtM 14 of 2013 and UKHO Notice 4255(P). PDF below was amended again on 23rd September, 2013
