1. SEA REACH - LONDON GATEWAY GROUND INVESTIGATION WORKS - On or around the 14th August 2023 marine ground investigation works by Causeway Geotech Ltd will commence as part of DP World London Gateway’s extension project. The works, which are expected to last for two weeks, will be undertaken by Jack-up barge “HAVEN SEAJACK 1” (18m x 18m) in bore hole locations 1-11 as marked on the chart (see Notices to Mariners in the Local List) and a Van Veen Sampler on board vessel “MPV SEA DOG” in locations 12, 14 and 15 on the chart. Location 13 is not yet in use. The JUB will remain at each bore hole location (in green) for 8 to 12 hours; grab samples will take 20 to 40 minutes at the other 3 sites (in yellow). Workboat “MPV SEA DOG” will remain in attendance for crew transfers (via an Avon SR4 RIB), supplies and to act as tug vessel for the JUB moves between sites. A 100m exclusion zone around the JUB will be in place and coordination of contractors works between vessel movements at berth 3, construction works at berth 4 and these sampling works will be led by London Gateway. All vessels involved with the works will maintain a continuous listening watch on VHF Channel 68.
2. The Swale – Ferry Reach - Sheppey Crossing Inspection Work - work to inspect the Sheppey Crossing bridge structure is due to commence Monday 14th August 2023. Work to inspect the main navigable span is expected to be carried out on Tuesday 15th and Wednesday 16th of August 2023 between the approximate hours of 21:00 – 04:00, this will involve inspections of the underside of the bridge using of an underbridge access rig mounted on a lorry. The use of this access machine will mean that roped access scaffolding will not be required to reach and inspect the underside of the structure and enable work to be undertaken quickly, effectively with the least impact to the Swale Navigation and Sheppey Crossing users. The safety boat ‘Protector’ will be stationed adjacent to the bridge at all times that work is underway, Protector will be in contact with the inspection team, the Kingsferry Bridge operator and will monitor VHF Channel 74 at all times. Commercial shipping movements will not be affected, however, ship’s transit times will be passed to the inspection team who will retract the machinery to allow vessels to pass safely. Admiralty Chart No. refers. 2572. Further information may be obtained from Medway VTS on VHF Channel 74, call sign “Medway VTS” or telephone 0151 949 6148 or 0151 949 6650. (Recorded lines)
