Temporary Relocation of Mid-Swatch Buoy

Mariners are advised that, on or about Monday 1st July 2024, the Mid-Swatch Buoy will be temporarily relocated from its charted position to the following position: - 

 Latitude 51˚ 28’.87 N 

Longitude 000˚ 43’.32 E 

 This is being carried out to facilitate the progress of the NeuConnect electricity cable project and will be performed by PLA Marine Services vessels and personnel.  

 The chartlet below shows the general area, with the current charted position of the Mid-Swatch Buoy circled in blue and the temporary position indicated in red:

Vessels should continue to report to VTS, as required, at the charted Reporting Point. The Mid-Swatch Buoy is expected to remain in the temporary position for approximately 12 weeks, after which it is expected to be returned to its former position. A new Notice to Mariners will be promulgated when the buoy is returned.  

During the buoy relocation works, requirements to proceed with caution or at slow speed will be made in accordance with the procedures set out in the Port of London Authority’s Port Information Guide, under ‘London VTS’, ‘Section 4’ with the International Code Flags ‘Romeo Yankee’, which are illustrated below, displayed.  

The display of these signals will be in addition to any lights or shapes required under local regulations and the International Regulations for Preventing Collisions at Sea.  

Further details will be broadcast as appropriate by London VTS on VHF channel 68.
