A ‘dangerous wreck’ close SW by the Colne Bar buoy. No more confirmed detailed at present.

Dredging on the Fagbury end of the Trinity Container wharf is now complete to 16.5m. We can assume that the largest container ships will berth there now.
4. ENGLAND - East Coast - Wreck. Depth. - New wreck just north of the Yantlet Shipping channel off Leigh. But at 7.6m unlikely to hinder leisure craft.
5. EAST COAST OF ENGLAND - APPROACHES TO LOWESTOFT -HOLM CHANNEL - This Trinity House notice is advising the move of the North West Holm and West Holm buoys. The NW Holm move is significant. see the image as above.

1. These will be familiar by now: Harwich Haven Channel Deepening Project: Dredging with backhoe dredger Goliath and Barges:

From around 30 August, for a period of about seven weeks, the backhoe dredger Goliath will be dredging in the main channel together with the self-powered, split-hopper barges, Pieter Caland and Cornelis Lely. The dredger will be supported by the tug, Buzzard. The dredging contractor is the Boskalis Westminster / Van Oord Joint Venture appointed by Harwich Haven Authority to carry out the Harwich Haven Channel Deepening Project. The dredger will be operating in a number of locations in Dredge Areas B, C and D within the main channel from the Fort Buoy out to No.1 and No.2 Buoys. (See attached sketch HHA: B/C/D on the above quoted web page using the Local List) For detailed information regarding the location of the dredging plant, please contact Harwich VTS or listen to the daily Channel Deepening VHF broadcasts. The backhoe dredger is located with three spud legs and will excavate strips along the channel, loading material into a split-hopper barge moored alongside. When full, these barges will sail to the Inner Gabbard East disposal site and discharge. If required, the backhoe dredger will move out of the channel to facilitate passing vessels and will wait outside the channel or in the Platters anchorage. Moves out of the channel or between cuts, will be assisted by the tug, Buzzard. The following traffic organisation measures will apply when working in the main channel in areas B, C and D:
• The Goliath must be clear of the Deep Water Channel before any vessel greater than 310m LOA is committed. This applies to vessel arrivals and departures.
• One way passing will be in effect where the available navigable width in the Deep Water Channel has been reduced due to the Goliath.
The split-hopper barges, the Pieter Caland and Cornelis Lely, will be disposing material in the Inner Gabbard East disposal site. Given the increased frequency of vessel movements and dredging operations mariners are reminded of the importance of regulated vessel reporting requirements and necessity to maintain a listening watch on channel 71 and good lookout ahead and astern. Detailed vessel movements can be obtained from Harwich VTS on VHF channel 71.
