The vessel “Liftmoor” will be on site from Monday 1st June 2020 and will be working for approximately 5 days to remove the bow section and parts of the superstructure that are causing a hazard to navigation. The operation will involve cutting/grinding of the steelwork and due to the nature of this “hotwork” passing craft are requested to navigate with caution. “Liftmoor” will maintain a listening watch on VHF Channel 74 at all times.

This notifies the restricted area of the Norther Wind Farm, submarine cable and lights changes within Zeebrugge. Refer to the images in the notice in week 21 or use the usual download button. (Notices to Mariners). I can’t see any changes between the two!
3. ENGLAND – East Coast – Depth. – One reduction of depth west of the West Shoebury Port Hand Buoy. At 11.5m unlikely to hinder leisure craft.
4. ENGLAND – East Coast – Harbour limit. Legends. – Limits for the Lowestoft Pilotage Area.
5. ENGLAND – East Coast – Harbour limit. Pilotage. – This Notice repeats the previous notice so as to include UKHO chart 1535. This includes the Lowestoft Harbour limit across the harbour entrance in this notice.
6. ENGLAND – East Coast – Depths. – A series of 6 revised depths in the central line of the DW water channel in the Black Deep adjacent to the Long Sand Head. Unlikely to hinder leisure craft (and not really best for us to be there!)

This notice is to include the correction for UKHO chart 1534 and is therefore a precautionary Preliminary Notice as a new edition of Chart 1534 has been postponed – now to mid 2020.
8. ENGLAND – East Coast – Moorings. Works. – Medway (Peel Ports) local NtM No 25 notified us in week 22 of the mooring of two drilling rigs alongside Berth No 10 at Sheerness. Two images: one detailed, one general location.

11. BELGIUM – Restricted area. Wind turbines. – This notice is a Preliminary notice additional to Notice 3096 above. This shows the Northwester 2 Wind Farm in a more detailed scale including the positions of the individual wind turbines. It is not my fault that one turbines is outside of the Wind Farm limits!

River Stour – Kent – EA Works at Pillory Gate Wharf – Masters of vessels navigating through the area of Pillory Gate Wharf are notified that the Environment Agency (EA) are placing a steel work barge at this location. The barge will extend 8 meters into the fairway. The EA will have two vessels acting as Guard Boats, which should be contacted to arrange safe passage through the area. Vessels should be prepared to stop if instructed. Notices will be displayed advising mariners to make contact on VHF Ch 08 or by mobile phone on the number given on the notices.The barge will display an all round ‘Special Mark’ flashing yellow light at all times.

6. River Stour – Kent – Sandwich Fairway Buoy off station. – Information. – The Sandwich Fairway Buoy has been recovered and is found to have suffered damage to it’s underwater balance weights structure. It is now under repair and will be back on station as soon as parts for its repair are received and fitted.
7. Port of Wells – Dredging – Life is back to normal!
8. Blakeney Harbour – The followings buoys have today been positioned to mark the new entrance channel into Blakeney Harbour: HARBOUR ENTRANCE STARBOARD NO. 1, FlG(5s), N 52° 59.039’ E 000° 57.800’: HARBOUR ENTRANCE STARBOARD NO. 2, Fl(2)G8s, N 52° 59.025’ E 000° 57.952’: HARBOUR ENTRANCE STARBOARD NO. 3, FlG(4s), N 52° 58.976’ E 000° 58.030’. Mariners should note that sand banks are building in the area between HARBOUR ENTRANCE STARBOARD NO. 3 buoy and HARBOUR ENTRANCE STARBOARD NO. 4 buoy. Vessels should therefore keep well East of a transit line between these buoys in order to avoid shallow water.
9. London Array Wind Farm – good news. Their weekly work schedule has stopped notifiying of the 500m exclusion zone which partially restricted Foulger’s Gat around Turbine C17. So as news about that exclsuion zone has gone, I conclude thre Gat is completely free. They continue to ask vessels to call up any LA craft before entering the Wind Farm.
