They seem to have us over a proverbial barrel. I don’t know how long the silt situation and tidal issues can carry on for, but the SPC may as well have the Arrow on permanent standby. Could the SPC have used the Mannanan? They already have the Arrow on permanent standby. Have had for years. They occasionally sub charter, with a break clause in case of IoM need. Heysham is a mix of silt and tides. The tides are predicable and can be planned ahead to an extent. The silting is a strange phenomenon. There’s been dredging ongoing for almost 3 months. There’s no river flowing into Heysham, so any silt/sand is brought in by the tide. The issue for the Steam Packet is operating to a fairly inflexible timetable due to carrying passengers. The silting/low tide doesn’t affect SeaTruck or Stena to the same extent. Quote Link to comment Share on other sites More sharing options...
monasqueen Posted December 31, 2021 Share Posted December 31, 2021 There seems to be some correlation between the recent build up of silt in Heysham Harbour and the deterioration of the large woodwork pier just outside that now lets water, sludge, and discharges from the power station through almost without hindrance. 1 Quote Link to comment Share on other sites More sharing options...
Non-Believer Posted December 31, 2021 Share Posted December 31, 2021 No newspapers today apparently, delivery wagon failed to make boat's early departure from Heysham (3FM News). Quote Link to comment Share on other sites More sharing options...
monasqueen Posted December 31, 2021 Share Posted December 31, 2021 Not quite accurate. Whites have reported that: Friday 31st December the only titles to make this mornings early departure is FT Guardian Racing Post 1 Quote Link to comment Share on other sites More sharing options...

Except no. That’s not how it works, nor is it that simple. I don’t think a wooden jetty, like a pier, not solid, just lots of legs in the seabed, with substantial gaps between the legs, is going to make much difference to silting at Heysham, whether it stands or falls. Nor will “clean” coolant water from Heysham nuclear, no sediment and volume isn’t huge. The oil terminal pier at Heysham was designed to allow tidal flow through, with minimum disruption either way. It’s a fundamental of pier design. With Heysham, a totally artificial harbour, gouged out of the rock and mud of a tidal inlet at the south end of Morecambe, with no natural flow it’s more likely to have been aggravated by channel changes in the various rivers flowing into Morecambe bay. The last 40 years has seen huge ( and natural ) changes in how they snake across the sands and mudflats. Shore level at Hest Bank shore lowered by 6 metres, removing all the salt marshes and exposing the early C19 canal company landing stage that hadn’t been seen since late 1890’s. And after 20 years it’s slowly being reclaimed. As for Douglas, the groynes were to retain sand. Removing them allows scour, but whether that ends up in the harbour isn’t a given. Clearly all the breakwaters, piers and jetties, including the outer breakwater, change flow and current, as do the marina flaps etc. The modelling is really complex. 3 hours ago, monasqueen said: There seems to be some correlation between the recent build up of silt in Heysham Harbour and the deterioration of the large woodwork pier just outside that now lets water, sludge, and discharges from the power station through almost without hindrance. Anyway, there has been ongoing dredging at Heysham for nearly 6 months. Including early today. Quote Link to comment Share on other sites More sharing options...

2112 Posted January 17, 2022 Share Posted January 17, 2022 Guernseys Government is going into a joint venture with Condor Ferries, whereby the Government are putting up to £20million with Condor putting up the rest towards a new ferry. Condor would run the service. It’s caused ructions with Jerseys Government. Perhaps the above may have worked well for here? Quote Link to comment Share on other sites More sharing options...
