[UCanoe_2]

Sister ship of the one that blocked the Suez Canal last year.

Ever Trouble.

[Thad Van Gilder]

Its right off my dock (in Rock Hall)... drawing 42 feet, but currently in 20 feet... she will be hard to get out of there....

[John B]

Probably it's in the name.
Coincidentally, I also had a jam up in the hallway to my back door last year.

Yes, the Ever Scram got stuck in there so I had to go all the way around the front to go to the shops.

Ever Forward into the mud of the Chesapeake. This is going to be another interesting salvage b/c she is so jammed in there. Perhaps a major amount of dredging in the coming days...

[Andrew Craig-Bennett]

Evergreen are a good outfit. They did make a mistake sending the Ever Given into tha Suez Canal without a tug on a day with a strong cross wind (a Shell gas carrier declined the transit and our ship of the same size as the Ever Given and just ahead of her took one of the Shell ship’s two compulsory tugs) but the Pilots must have been happy.

This looks like another grounding under pilotage but we must wait for the NTSB report.

[Bob Adams]

I am very familiar with where she is stuck, it is just past a dogleg in the channel. Looks like they didn't complete the required turn to the south. According to a meeting the USCG which I attended, they will not attempt lightering, rather they will dredge around and behind her then attempt to back out with the aid of tugs and her main. She was drafting 42 feet and is in 20 feet of water. That meeting was held in the Maryland Pilots building, she was under command of a Bay pilot but obviously they would not speculate on a cause at this time.

How does a boat that draws 42 feet, get itself into water that's only 20?

[JamesCaird]

Not exactly sure here but alot of Chesapeake bay is sort of ....chocolate mousse sort of stuff, and sticky.

[hawkeye54]

Are we 'sure' that the pilot / skipper wasn't confusing the Chesapeake with some ship breaker area, and was trying to run onto the beach so the ship could be broken up ? ? ?

Jeff

ran into some fish pots and got them wrapped around her screw?

[Breakaway]

An astronomically high tide, combined with wind from the right direction, can, along with the aforementioned mucky bottom, also help contribute to some of the seemingly implausible disparity between the vessel's draft and the water's depth.

[Bob Adams]

Mean water depth in that area is around 19 feet.The channel is dredged to 50 with a steep drop off. Get 35 feet out of the channel and you are in 18-20 feet. That is how, when they did not complete the coarse adjustment in the dogleg, they got that thoroughly grounded.

[dutchpp]

The guys of Boskalis will love this job, almost no time pressure, simple dredging followed by some towing >> ca$h.

[Andrew Craig-Bennett]

This will be a day rate job, not a Lloyds’ Form.

Translate Lloyds Form to American please.

Thanks.

They are making the first attempt to refloat now. https://www.milfordmirror.com/news/a...r-17034546.php

Dredge… tow… dredge… tow… dredge… tow and in the end she comes afloat.

I looked out my window and can see we have a blowout tide, a good 4 feet lower than a normal low tide. They picked a bad day to try.

Doesn't that mean that high tide will be bigger than normal?

[Peerie Maa]

No, High atmospheric pressure, an anticyclone, can depress the tide, it is called cut in the trade, just as a deep low can lift a high tide causing a storm surge.
We used to allow for a foot of cut when calculating for our dynamic launches.

[Andrew2]

Just curious, but what is the tidal range there. I always thought it was very narrow?

[Woxbox]

Right. Just a couple of feet generally, but highly variable.

[Woxbox]

I see mention of pulling barges to be used if the first attempt fails. That's a new one to me. Is it an anchored barge with a massive windlass on the deck?

[Ian McColgin]

One of the better not-too-technical accounts of yesterday's failed effort is at https://gcaptain.com/ever-forward-re...-unsuccessful/

[Bob Adams]

Normally that's correct, maybe 2 feet BUT a strong sustained NW wind like we have had blows the water out of the Bay. We were a good 4 feet below a normal low.

[willmarsh3]

In my experience on the Chesapeake in Deale, MD the tides were around a foot. But if the wind blew in the right direction it would lower the water by an additioal 2-3 feet. I panicked once seeing my boat sit on her side in the mud. She was held up only by the dock lines. I returned a few hours later to see her floating upright. I have also seen the water rise about 3 feet as a hurricane passed over. There was once an extreme case where Isabel caused a rise of 7' and flooded much of downtown Annapolis.

Anchored barge - with specially made anchors - and usually a very large wire rope purchase on the deck. The fall goes not to a winch but to a tug. It’s a way of multiplying the bollard pull of the tug(s). I remember that Luzon Stevedoring used to be very expert at it when Don Marshall owned them, back in the 1970s.

[Andrew2]

Thanks all on the tidal range.

There must be some interesting engineering going on when they set this up. Huge loads all around. I wonder they don't risk tearing a chunk out of the grounded ship.

That can happen.

[Bob Adams]

Looks like they are shifting gears, at the meeting I attended a few weeks ago, the Coast Guard indicated lightening the ship would be the last resort. Yesterday they announced plans to start offloading containers. Should be interesting.
