1. ENGLAND - East Coast - Depths. - This preliminary Notice is a continuation of the series of preliminary notices advising reduced depths from Winterton Ness to Benacre Ness. This notice adds 3 reduced depths at the Hemsby Hole and North Caister. The images includes all other reduced depths in the area reported this year.
2. ENGLAND - East Coast - Buoyage. - This permanent notice is confirming buoy moves reported earlier by Trinity House (TH21 of 2024). The moves affected were the SW Holm SHB, South Holm SCB, Newcome Sand PHB and the Stanford PHB.
3. ENGLAND - East Coast - Depths. - Two reduction of depth in Gallions Reach, River Thames. Unlikely to hinder leisure craft.
4. ENGLAND - East Coast - Depths. - One reduction of depth in Gravesend Reach, River Thames, east of the entrance to the Embankment Marina. Unlikely to hinder leisure craft.
5. ENGLAND - East Coast - Buoy. Light-beacon. - Establishment of a new Yellow special lit buoy in the channel to Kings Lynn. Back in July local notices reported the damage and loss of lit beacon ‘B’ following a collision with a fishing vessel. The yellow special buoy replaces the mark approximately 20 m south of the remains of the old beacon which is now regarded as ‘FOUL’ ground.
6. DOVER STRAIT - Depths. - Five reductions of depth in the SW bound TSS between the South Falls NCB and the F1 Special buoy. Very unlikely to hinder leisure craft!

During these operations, vessels will begin berthing at the western end of the berth. All vessels excluding vessels undertaking ship towage operations are required to maintain a 75-metre exclusion zone from vessels either berthing or unberthing at Berth 3 or the western end of Berth 4, as well as from barges and fixed structures. Additionally, a 100-metre exclusion zone for all vessels including those undertaking ship towage operations, must be observed from divers in the water. Diving Operations will be taking place 24 hours per day. When diving is taking place, vessels engaged in diving operations will display the following in accordance with Byelaw 33:
By day, International Code Flags ‘Romeo Yankee (RY)’, ‘Alpha (A)’ and a red flag near the diver’s point of entry into the water
By night, illuminated rigid replicas of the International Code Flags ‘Romeo Yankee (RY)’ and ‘Alpha (A)’

Work to replace the sheet piled berth face is due to commence on or around 4th November 2024 with completion expected in February 2026. Work will be carried out in two phases and will predominantly be completed from behind the existing berth edge where a new quay wall will be constructed before removal of the existing sheet piling. Whilst works are underway, contractors will be working on the quay edge and on the waterline towards the final stages of construction. All vessels are requested to pass Euro Wharf with caution, minimise their wash when required, be aware of safety craft operating along the berth edge and monitor VHF Ch.74 at all times.

The TSHD “Vox Apolonia” will commence dredging on or around 06.11.2024 and will dredge over a number of tides with completion expected within 3.5 – 4 days. An intermediate survey will then be carried which will reveal any high spots left from the initial dredge operation. The WID “Maas” is then due to mobilise to site on or around 14.11.2024 to carry out a levelling off campaign with completion expected by 23.11.2024, approximately. “Vox Apolonia” and “Maas” will display the required signals for respective operations by day and night, all vessels transiting the Medway Approach Channel are requested to navigate with caution, maintain a listening watch on VHF Ch.74 and reduce speed and wash if requested to do so.

On the 29th from 1445-1745 the Eastern entrance will be closed to all shipping (except cargo vessels which cannot safely use the Western entrance) to facilitate dive inspection of the end of the arm. This inspection may be cancelled at short notice should the following criteria be exceeded: Tidal stream is greater than or equal to 1 knot; Wave height exceeds 1 metre; Wind speeds exceed 20 knots.
