UKHO Permanent/Preliminary/Temporary

Week 10:

1. New Editions of ADMIRALTY Charts published 07 March 2019 - Chart 105 England - East Coast, Cromer Knoll and the Outer Banks 1:75,000 - Includes changes to depths from the latest British Government Surveys.
2. NETHERLANDS - Foul. Buoyage. - A new foul close to the Botkil Rassen bank off the coast off Walcheren. The new power cable notified in NtM 428(P) is close by and so shown on the image. Note 4 light buoys marking the Foul have been positioned but no details available. See image and all others on: http://www.crossingthethamesestuary.com/page9.html
3. BELGIUM - Light. - The existing MOW4 light north of the Scheur channel is no longer Yellow.
4. BELGIUM - Depths. - Preliminary Notice - 10 reduced depths on the Fairey Bank outside the Noord Hinder South TSS. Depths unlikely to hinder leisure craft but the bank has decreased depths overall. The other single reduced depth is on the north tail of the Noordhinder bank; again with adequate depth for leisure craft.
5. ENGLAND - East Coast - Depths. - 13 reduction of depth on the Haisborough Sand, the Haisborough Tail and Hammond Knoll. Some dramatic changes but not an area I suspect many would frequent. The image includes the one reduction of depth on Hammond Knoll vide NtM 715 earlier in the year.
6. FRANCE - North Coast - NM Blocks. - Two UKHO blocks for the two charts quoted, nos 323 and 1892 (1351 new chart already issued). Only one image shown as they are very similar but both can be downloaded on the left on the above page (and are useful).
7. BELGIUM - Depths. - a permanent NtM: These reduced depths are identical to NtM 1161(P) (No 4 above). The image above can be used for this NtM.
8. BELGIUM - Light. - a preliminary NtM which is identical to No3 above.

Week 9

9. ENGLAND - East Coast - Pontoon. Jetties. - Removal of the pontoon and jetties in the Waveney Dock, Lowestoft;

13. NETHERLANDS - Lights. Depth. - Preliminary Notices - This Preliminary notice replicates the notices 1096 (No 11. about the light ranges) and one of the reduced depths about notice 1116 (No 12 above). !!!

Week 8

14. RADIO NAVIGATION WARNINGS (RNW) –NEW E--MAIL ADDRESS - Please note that from 1st February 2019 all urgent navigational information should be sent to navwarnings@ukho.gov.uk

A Zeebrugge. B Brugge.
16. ENGLAND - South East Coast - Depths. - Three reductions of depth on the west side of the Goodwin Knoll indicating that the sands have migrated a little to the west. The Gull Stream buoyage remains as before so the Goodwin have not moved that much.

Local Notices

1. TOWER PIER TO SHORNMEAD LIGHT SUBSURFACE TOWED EQUIPMENT SURVEY - From 24th February 2019 survey works will be carried out along the River Thames between Tower Bridge and Shornmead Light. The survey will be carried out by a PLA Survey vessel which will deploy subsurface towed equipment up to 200m astern of the vessel. When carrying out the survey the PLA Survey vessel will be restricted in its ability to manoeuvre and will display lights and shapes in accordance with the International Regulations for Preventing Collisions at Sea 1972 (as amended) Rule 27 b. The vessels will maintain a listening watch on the appropriate port VHF working channel throughout the working period. All vessels are required to proceed with caution past the survey vessel when work is underway and at all times when advised by London VTS. The latest survey position will be updated by London VTS through the routine broadcasts made on the appropriate port VHF working channel. Survey work is due to be completed by 1st March 2019 but this may be extended as a result of prolonged periods of unsuitable weather or other operational requirements.
2. NORTHFLEET HOPE & GRAVESEND REACH NORTHFLEET UPPER LIGHT SECTOR LIGHT RELOCATION - On Tuesday 26th February at approximately 18:00 the Northfleet Upper Light will be switched over from its current location on top of the tower block (adjacent to Bevans 42) to the new PLA Radar Tower that has been constructed adjacent to the tower block. During the switch over there may be times when the light is not exhibited but this is expected to be only momentarily. London VTS will broadcast messages on VHF Channel 68 prior to any changes and confirm once all work is complete. On completion of this switch over the Northfleet Upper Light the sectors will be slightly out of position to that shown on PLA and Admiralty paper charts and in other nautical publications as well as on ENC cells. Chart corrections will be issued in due course. The new sectors are shown in magenta on the above chartlet with the following light characteristics being exhibited: Oc.WRG.10s.43m.10-7M
3. GRAVESEND REACH TILBURY2 UXO SURVEYS & DIVING OPERATIONS - Contractors working on the TILBURY 2 development will carry out UXO surveys off the former Tilbury Power Station Jetty in Gravesend Reach. Starting the week commencing 25th February the flattop barge NEPTUNE will be positioned at various locations within the UXO investigation area shown above from which diving operations will be carried out with the assistance of a barge mounted long arm reach excavator. Barge set-up and positioning will be supported by MPV SEADOG which will remain in attendance throughout diving activities. During the diver operations flag code ‘ALPHA’ will be displayed along with flag code ‘ROMEO YANKEE’ in conjunction with a broadcast “Proceed with Caution” request by London VTS at all times diving operations are underway. No vessel other than those engaged in the surveys will be permitted to enter the UXO Investigation Area. Survey works are expected to be completed by 10th March 2019.
4. Removal of Temporary Mooring Installation – River Stour - Mariners are advised that the temporary trot moorings and associated plant positioned in the River Stour between the following approximate positions: 51 ̊ 56.96 N 0001 ̊ 12.00 E to 51 ̊ 56.93 N 0001 12.93 E - have been removed from site. (that's the pipeline moorings)
5. River Crouch - PLA Survey Works - will commence on the river Crouch on Friday 1st March 2019. The survey will be carried out by PLA Survey Vessel MAPLIN which will maintain a listening watch on VHF channels 11 and 16.

On the Crouch the survey extends from Brandy Hole Reach in the West to the Buxey Sand in the East. On the Blackwater the survey extends from Osea island in the West to Colne Bar in the East.

The survey will be carried out by PLA Survey Vessel “MAPLIN” which will deploy subsurface towed equipment up to 200m astern of the vessel which will be marked with a tail buoy. When carrying out the survey the PLA Survey vessel will be restricted in its ability to manoeuvre and will display lights and shapes in accordance with the International Regulations for Preventing Collisions at Sea 1972 (as amended) Rule 27 b. The vessels will maintain a listening watch on the appropriate port VHF working channel throughout the working period. All vessels are required to proceed with caution past the survey vessel when work is underway and at all times when advised by Crouch Harbour Authority. Survey work is due to be completed by 10th March 2019 but this may be extended as a result of prolonged periods of unsuitable weather or other operational requirements. This notice will be cancelled on completion of the surveys.
6. Barton Hall No 3 Lighted Buoy – River Roach - Barton Hall No 3 Lighted Buoy in position: 51˚ 34.924’N 000˚ 45.886’E is out of the water for maintenance. We will advise when it is back on station.
7. Brightlingsea Town Pontoon Maintenance period 18 to 28 Feb 2019 - town pontoon will be having some maintenance carried out upon it. This means there will be periods when the hammer head section will not be connected to the pontoon, between the period of the 18th to the 28th Feb. Vessels are advised to call the harbour on VHF channel 68, to confirm that the hammer head can be used prior to landing.
8. Navigation Lights at Ipswich Tidal Barrier - the following IALA approved Navigation Lights are now in operation at the Ipswich Tidal Barrier in the new Cut. On the Western side marking the Northern and Southern ends of the Barrier we have two pairs of all round Red lamps located 2m above MHWS. There are two pairs of Green Lights marking the Eastern side of the Barrier North and South. When the Barrier is raised and closed for Navigation, this is marked by 3 red Lights in a vertical line one set at the Southern side and another set at the Northern side of the Barrier. These lights are illuminated as soon as the barrier starts to move. The official opening of the Tidal Barrier was scheduled for Friday 8th February 2019.
9. BROADS AUTHORITY - Update - Works to Mutford Lock Road Bridge - Urgent update to all Mariners. Notice is hereby given that major maintenance works to Mutford Lock road bridge are being undertaken by Suffolk Highways from Monday 11 until Friday 22 March 2019. The road bridge will not be able to be raised for the duration of the works and Mutford Lock will also be closed to navigation from Monday 11 until Friday 15 March 2019. Clearance for vessels using Mutford Lock from Saturday 16 until Friday 22 March 2019 will be restricted to 2.4m at mean high water and 4.2m at mean low water springs. After maintenance works are completed, Mutford Lock will be opening on normal winter hours between 8am-12pm during this time.
10. London Array Wind Farm - Current Safe distances within the Offshore Wind farm:
• A 50m radius advisory caution zone is established around each wind turbine and offshore substation platform (Normal).
• A long term 500-meter exclusion zone has been implemented around D20 - (51° 38.024'N 01° 24.612'E) as a precaution until further notice due to a damaged blade. (Lond standing - out of our way)
• A short term 500-meter exclusion zone has been implemented around C17 - (51° 37.132'N 01° 25.641'E) this location stands in the Foulgers Gat channel and a wide approach is requested. (Interesting that they are not 'closing' the Gat but they like us to call up any LAL vessel prior to enter)
• The MPI Adventure will move from WTG to WTG, spending approximately 36-48 hours at each location. When located at a WTG, a 500m radius exclusion zone will be put in place centered on the MPI Adventure.

That's it. All images available for the Local NtM can be found on the above quoted page in the Temporary list and with the full details of each notice.
