And for those who do not believe in CONSPIRACY THEORIES.....here is your needed proof....
I'm a former sailor and certified master helmsman. I give a breakdown of the Key bridge incident in Baltimore harbor using professional ship simulation software.
Yes, but we do not yet know how fully (or not) she was loaded...the prop walk only occurs if she is so light that a portion (to half) of the prop is not even in the water and actually helping to propell or slow the ship...the prop blade pushes the ship's stern in the opposite direction in reaction to the blade pitch at the bottom half of its rotation in the water.
if they get at least 3 large cranes of 1000 - 3000 tonne they could pick out the biggest pieces in chunks of 200 - 300 tonne.Yes, but we do not yet know how fully (or not) she was loaded...the prop walk only occurs if she is so light that a portion (to half) of the prop is not even in the water and actually helping to propell or slow the ship...
We still need more info towards that.
No matter what, there is still years of problems with the bridge in the water, unless they clear the main canal of depth so as that other ships can get thru till the rest of the bridge is cleared and maybe re-built...
I would get the bridge cut into small piece of 10 - 15 tons, chain them to tugs and drag them somewhere (anywhere) to clear the path needed to get other ships moving thru the harbor...or even pick them up with barge cranes and get them completely out of the harbor.
I like the flotation idea.if they get at least 3 large cranes of 1000 - 3000 tonne they could pick out the biggest pieces in chunks of 200 - 300 tonne.
remember a crane rating is at "zero metres" (20m) from slew center.
If they get divers to pull rope under the sections in 3 - 4 places and tie them off they could pull diamond wire through and cut the sections up from bottom to top with the diamond wire , do it from an anchored barge and keep humans well away from the danger zone.
another option is flotation bags to lift the sections half out of the water and tow them to shallow water as you mentioned.
I wont be surprised if there are engineers already designing a new bridge to be built next to the old one as full demolition could take 12 months even on an accelerated plan.
