Week 35

ENGLAND - East Coast - Thames Estuary - Traffic separation scheme.

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.

as it is being installed, with a safety zone of 500 metres around the installation vessel.

*Cable laying operations are being conducted between Galloper Wind Farm and Sizewell Power Station at (52° 12´·36N., 1° 37´·39E.)

Charts will be updated to show the works area in due course.  For latest information see Galloper Wind Farm Notice to Mariners.  Former Notice 2475(P)/16, is cancelled.  *Indicates new or revised entry.

Note:  The Galloper Wind Farm web site shows the projected timetable as showing that the second and final cable should have been installed in May and the Offshore Sub-station installed in the ‘Summer’.  It would seem that there is some slippage.

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.
