Week 40


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.

Channels.


Source: Port of London Authority & Trinity House


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 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

I have revised the CTTE drawing to show this NtM as well as the earlier week 18 notice.

Week 5


London Array - Reduced clearances at the Kentish Flats and BritNed cable crossings.


Kentish Flats cable crossings (51° 25'.217N, 001° 06'.033E).


At these three crossings the typical sea bed level was -4m LAT. Due to the newly installed rock berm the depth in some areas is now -1.5m LAT.


BritNed cable crossing (51° 28'.583N, 001° 17'.417E).

At this crossing the seabed level varies from -6.5m LAT to -9m LAT. Due to the newly installed rock berm the depth in some areas is now -4m LAT.


The start and end coordinates of the rock berm are given in the following tables


Crossing:


Kentish Flats


From: 51° 25'.203N 001° 05'.895E  to 51° 25'.252N 001° 06'.169E


BritNed


From 51° 28'.549N 001° 17'.372E  to 51° 28'.599N 001° 17'.457E

Note this is not a UKHO NtM as yet but issued by the London Array.  It provides details of a serious reduction in depths particularly where the London Array cable passes over the cable from the Kentish Flat Wind Farm.


A rock berm is a rock barrier wall.  There is no information as to its construction but it can be assumed to be substantial enough to provide protection and stability to the cable crossing.  Whether these will be marked is not known at present.

This Notice whilst quite lengthy because of all the variations for different Admiralty Charts effectively comprises two messages for commercial shipping: first a warning to crossing traffic in the Dover Straits leaving the north-east going lane and crossing the south-west going lane.  Second, guidance about use of the Sandettie Deep Water route (for vessels with a draught of 16m or more) and the use by vessels of less than 16m draught of the main lane south-east of the Sandettie Bank.


It follows that leisure vessels should not be in the Deep Water route!   


The notice comprises blocks (all similar within their subject) for pasting on Admiralty Charts.  All can be downloaded here as PDF files for cutting and pasting.

This is rather a long notice for one addition to show the position of the London Array.  Each of the Admiralty charts of the area has slightly different lat/long references which for the most part are of little consequence.

New wreck on that part of the Long Sand between Foulger’s Gat and Fisherman’s Gat.  It is on the shallow side of the 5m contour line  at the south west side of Foulger’s Gat.  Keeping close to the Long Sand Outer safe water mark should ensure it is avoided.

Removal of all buoyage for the Knob Channel.


Knob Channel leads from the Knock John Channel (at the bottom of the Black Deep) to the South and North Edinburgh Channels.  Since the Edinburghs are no longer marked themselves, there was little point for Trinity House to retain this buoyage.


This means there is nothing between the entrance to the Princes Channel and the NW Long Sand Beacon to mark the Shingles.
