Pipe Deployment in Copperas Bay - River Stour- marine operations involving the assembly and temporary deployment of a dredge material deposit pipe will be taking place in the River Stour, at Erwarton Anchorage and Copperas Bay as follows:
26 February 2026: deployment of temporary anchors in Erwarton Anchorage by multi-cat tug Willdiscover (IMO: 1112525) in the following locations:
East Anchor, 5 tons 51° 57.060’ N 001° 13.164’ E Buoy with white LED Light & retroreflective tape
West Anchor, 5 tons 51° 57.060’ N 001° 13.050’ E - ditto buoy
28 February 2026: towage of 4 x 90m length floating pipes (in parallel) to Erwarton anchorage moorings and assembly into single 360m pipe, by Willdiscover and MTS Valour (IMO: 9407299).
02 March 2026: Tow 360m floating pipe to Copperas Bay and connect to shoreline.
1 Dredger Connection point at Low Water 51° 56.886’ N 001° 14.118’ E 80m
2 Dredger Connection point at High Water 51° 56.862’ N 001° 14.094’ E 80m
3 Anchor Wire Connection A 51° 56.856’ N 001° 14.148’ E 290
4 Anchor A1 51° 56.862’ N 001° 14.172’ E
5 Anchor A2 51° 56.844’ N 001° 14.124’ E
6 Anchor Wire Connection B 51° 56.760’ N 001° 14.256’ E
7 Anchor B1 51° 56.754’ N 001° 14.286’ E
8 Anchor B2 51° 56.742’ N 001° 14.250’ E
Willdiscover will be acting as Guard vessel for the pipe during assembly and post-deployment in Copperas Bay. Guard vessel Willdiscover – 24m Length Overall – callsign MSJD6
The dredger Sospan Dau (IMO 7711062) will be undertaking deposit of dredge material at the Copperas Bay floating pipe and to the beneficial sites in the River Stour and Orwell (diagram below).
Usual beneficial deposit sites used by dredger Sospan Dau in Rivers Stour and Orwell
Mariners are requested to pass at a safe distance. The dredge material deposit pipe is expected to remain in position until approximately 15 March 2026. A further Notice to Mariners will be issued when the pipe is to be removed.

looking at the so called "beneficial deposit sites" it looks to me a bit like sweeping the dirt under the carpet or even chucking it over your neighbours fence! It would seem to me that the sediment is simply going to wash up and down the river and make the entrance to SYH and inside the marina even shallower!!
Which of course SYH then has to dredge out again. Always good to make it someone else's problem isn't it?
