Works are expected to take no longer than 10 days and will be undertaken in daylight hours only.  

Trawling Operations will be completed between the 27th and the 30th October, in Woolwich Reach, Gravesend Reach, and the Southend Anchorages, at a speed of no greater than 3 knots. Works are estimated to take no longer that 60 minutes in each location. 

Sediment Sampling and Grabbing Operations will be completed between the 5th and the 7th November in 15 locations across multiple districts. Each sample will take no longer than 30 minutes in each location. All locations are outside the authorised navigational channel.  

Vessels involved in operations include the “HUMBER GUARDIAN” and “SAORSA NA MARA”.
