1. ENGLAND - East Coast - Offshore installation. Works. - Outfall installation and beach nourishment works are taking place in the area defined is from Bacton south towards Happisburgh. Image at http://www.crossingthethamesestuary.com/page9.html
2. BELGIUM - Works. Wind farm. Buoyage. - Works are in progress to establish the Seastar Wind farm - The construction area for the new Seastar Wind Farm lies between the Belwind, Borssele and Rentel Wind Farms effectively bans us from a large part of Belgium waters. But perhaps not an area we would pass.

1. GRAVESEND REACH FLOODGATE REPLACEMENT WORKS GRAVESEND CANAL BASIN - Works that started on 12th November 2018 for the in-channel flood gate replacement works, will continue on the lock for Gravesend Canal Basin until the end of August 2019. The majority of the works will take place at low tide with a temporary cofferdam being installed. For this reasons a ‘Proceed with Caution’ will be issued by London VTS on VHF Channel 68 asking passing vessels to minimise their wash. Navigation through the lock will be managed by the on-site team on an ad-hoc basis
2. HALFWAY REACH FISHERIES RESEARCH HALFWAY ANCHORAGE & SOUTHERN OUTFALL JETTY - In June, August and October 2019 the ‘Zoological Society London’ will be carrying out fisheries research in conjunction with the Environment Agency to update statistics gathered in previous surveys in 1987 and 2011. The research will be carried out by deploying three FYKE nets in the vicinity of the Southern Outfall Jetty and Halfway Anchorage. The nets will be deployed subject to tidal conditions for approximately 24 hours at a time within the following dates:
3rd June – 14th June 19th August – 30th August 14th October – 25th October
London VTS will broadcast when the nets have been deployed as anchoring in Halfway Anchorage will not be possible at these times. The nets will not impede the main navigational channel.
The nets will sit on the river bed with a height of approximately 50cm and marked with temporary buoys to indicate their position. The nets will be anchored in position to align with the tidal flow at a length of up to 75m. The Environment Agency’s boat ROKER (a 6m aluminium, rigid buoyance workboat) will be in attendance at times to deploy and recover the nets. ROKER will be listening on VHF Channel 14 throughout their operations Images on the above page on the Temporary List.
3. Harwich Haven – Harwich International Port - Dredging operations using backhoe and water injection dredging at the eastern end of Parkeston Quay - on or about the 31st May 2019 pre-construction dredging operations will commence at the eastern end of Parkeston Quay. The vessels involved with this operation will be the water injection dredger Doomhamer and the tug Dutch Pioneer (towing the split hopper barge B1002). The backhoe operation at the Parkeston Quay site will be performed from the flattop barge GPS Boxer. The barge B1002 will be towed between the dredge site at Harwich International Port and the ‘Inner Gabbard East’ disposal site (TH056). This dredging operation is expected to last for a period of approximately 2 weeks.
All vessels are required to pass the dredge site with caution. Detailed vessel movements can be obtained from Harwich VTS on VHF Channel 71.
4. Approaches to King’s Lynn - Re-instatement of Light Beacon “Charlie” - replacement lighted beacon “Charlie” has been established in position 52° 48.759’ N, 000° 21.138’E. - The beacon is coloured yellow with a yellow cone topmark. The light character is: Yellow, 3 flashes every 10 seconds, height of light at 10.5m above dock sill.
This beacon is erected upon the western stone training wall which dries to a minimum of 4.0m above dock sill and extends in a southerly direction from West Stones Beacon (52° 49.697’N 000°21.131’E) to Kings Lynn and all craft should avoid crossing the Wall in the vicinity of any beacon.
Mariners are reminded of NtM No.1/2019 and are asked to note it is an offence to damage any Aid to Navigation and are also liable for all costs associated with making good any damage. !!!
5. NATIVE OYSTER RESTORATION – SPAT COLLECTOR FRAMES & MARKER BUOYS, WEST MERSEA - In June, works will continue for the Essex native oyster restoration project within a defined restoration box, of which the north-west corner is located approximately 500m offshore to the south-east of West Mersea (hereafter referred to as the ‘Restoration Box’). The Restoration Box is approximately 2000m (west to east) by 1000m (north to south) (demarcated by red line on chart below). The works will include the deployment of six spat collectors. These are A-frame structures that are approximately 1 metre wide, 2.4 metres long and 1.2 metres tall. The location of the spat collectors will be marked by six yellow marker buoys with a flashing yellow light. The total area will be approximately 100m x 120m. The works will be carried out from the vessel ‘Jean T’ (17m x 5m).
The deployment of the spat collectors is dependent on water temperatures. The works are anticipated to start 6th June 2019 or soon thereafter. It is anticipated that the installation works will be complete before 31st July 2019. During the works, mariners are requested to keep clear and avoid any unnecessary wash. On completion of the works, the six spat collectors and six marker buoys will remain on the seabed in the Restoration Box. Mariners are therefore requested to be mindful of these underwater structures in this location. Images on the above page in the Temporary List. Details in the list.
Havengore Bridge is reported open. Wells is not reported dredging.
That's it. I'll post this immediately before it wipes but my website is still uploading, probably 5 minutes time.
