This preliminary notice repeats the first two reduced depths in the earlier preliminary notice above.  The point of this is to notify the change for a different chart (viz 1975).  The image of the earlier preliminary notice already includes this notice so refer to the first of those three images.

Week  13

ENGLAND - East Coast - Depth.

Recent survey information has shown a depth of 14m exists in position 51° 30´·137N., 0° 36´·447E.

This is more about doing the housework than notifying a change of depth.  It is a preliminary notice about Chart 1186 for a reduced depth in the middle of Yantlet Channel which is covered in NtM 1650 above – which is for Chart 1185.  I refer to the image for NtM 1650!

This is a sad time when five useful marks are unmaintained and now declining.  Topmarks of each of the five beacons listed have now apparently fallen.  Unfortunately as the Middle Sand is a red and white beacon, this can now be regarded as a safe area once the stump has fallen below the HW.

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.

All vessels should navigate with caution in the area. A safety zone of 50 metres becomes operational around each turbine

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.
