Sea Reach to the Sunk – Buoyage Changes for the London Gateway Project

Sea Reach to the Sunk – buoyage changes for the London Gateway Project

This CTTE publication is intended to provide readers with illustrations and an overview of the changes brought about by the London Gateway project. Sea Reach to the Black Deep has been dredged to provide a deep water route giving greater depth for larger Container Ships and the buoyage reflects this and the increased traffic that is expected. The images are not intended to be used for navigation and only show buoyage and marks outside of the Sea Reach to Black Deep channel where it helps reference the position of changes.

The changes include the provision of new buoys, some small movements of existing buoys, swapping a cardinal buoy with a lateral mark and a couple of light characteristic changes, all of which are notified in Port of London Authority Notices 14 of 2013 and L16 of 2014, and Trinity House Notice 18 of 2013

It will be noticed that in the Black Deep Channel, three yellow special buoys will be established in what look like the centre of the channel. It has been confirmed that there is no intention to establish a two‐way traffic separation; rather that the special pillar buoys are there to indicate the deeper water in the Black Deep between them and the normal Black Deep buoys marking its southern edge.

In Sea Reach, the former central marks have been replaced with paired buoys marking either side of the Yantlet Channel. The small craft crossing points are not changed.

There is a clear obligation for us to heed the likely increase in shipping in the Black Deep which of course is restricted to a narrow channel, particularly in the Knock John. Please bear in mind that tidal rates in the Black Deep in particular can exceeds 2kts at certain times of the ebb.

This shows all the changes, movements and new stations and when these are expected. The List, which runs from West to East, also includes details of buoyage that remains unchanged. As these will be on your existing charts, their position is omitted.

The Images

Three are provided: Sea Reach, the Oaze Deep and Knock John extended into the Black Deep, and the eastern part of the Black Deep. These are not intended to be used for navigation. Light characteristics are only shown for the Sea Reach to Black Deep Channels. Note the small craft crossing point across the Yantlet Channel is shown on the Sea Reach image and the swatchways across the Sunk Sand are shown on the other two images. Details of the Sunk Sand crossing points can be found on the web site: www.crossingthethamesestuary on the Updates and Downloads page.

Please note, this version of the CTTE publication includes the one small correction to the position of Racon T in Sea Reach published in PLA NtM L14 of 2013, the images published by the UKHO in Preliminary Notice 4255(P) of 2013 and the changes notified in PLA NtM L16 of 2014.
