liquid or weight?
"But wait, there's more.".........
Volume? Pressure? Temperature?
A pressurized basketball weighs more than an empty one.
Full of hot air it would weigh less, for the same pressure.
Pressure (in a confined volume) goes up as it is heated.

That's it !!!
Why wasn't Dali just full of hot air ???

That, and if that sort of emergency arose without enough space available to swing bow and stern by use of the thrusters, it may still not be possible to avoid contact.
The thrusters' main intent is for positioning into the berth at the dock, for instance, not for primary steering while in forward motion.
These floating, multi-acre man-made bergs of immensity are not able to be turned and stopped like Uncle Remus' weekend party boat on Podunk Puddle Pond.
I'm beginning to think people who have not been around heavy equipment of any sort, see the aerial wide angle photos of Dali at the Key Bridge, and have no idea what the scale of size, weight, maneuvering characteristics are, because the Dali doesn't look like much more than Baby Bobby's bathtub boat in the long range, wide angle views.

What? Many people know how far a fully loaded trailer-truck needs to go to stop. Just look at the ones who cut back into lanes in which the semis are traveling. They cut in front of the rigs with a foot to spare.
The question I'd like to add to the pile: Why didn't the people on the ships shoot out the cables to wrap around the street lamp pole and force the ship to turn right or left. Batman does that just about in every turn. (Popeye did it a few times.)
NOTE: The above is done in a tongue in cheek.
Personal anecdote: Driving a fully loaded duece-and-a-half and pulling a water trailer up a hill in Wisconsin and having to push another truck with a company, pulling an arms trailer. The truck in front was with only half power air pressure and a inexperienced driver. Radios were used for communication, fortunately part of equipment we traveled with. Had to push our way uphill to reach a flat place. Granted it was not equivalent to the ship issue, but it exemplified how bad situations can happen. If it was not for me being there, they would have gone over the side and down the hill.

Interesting. So, not necessarily 2000 lbs. 40 cubic feet of socks might be considerably different in weight. This might explain why the ship, being listed at so MANY tons, didn't just continue to plow through to the other side of the bridge. The fact that it WAS stopped indicates to me that ships of this size, fully loaded, CAN be stopped.

Hoot mon !! Where was Pecos Bill, or Yosemite Sam??
Wasn't it one of those guys that lassoed a huge tornado that was barreling down on a county and a couple towns......certain destruction and deaths on tap.....then climbed his lariat up there and grabbed that big ol' twister around the neck, forced it to go away from all the people and buildings, then rode it to death out there in the pucker brush where it collapsed with a whimper, and the ol' bow-legged hero touched down on his feet....still had his trusty ol' time worn hat in his hand?

Yeah, mass, momentum and steering and stopping distances.
I'd post some stuff available on youtube, even, but it would probably be ignored by those who don't believe something like that container ship can't stop and turn in the radius of a drinking straw.
Neither will they probably believe those big ships will begin decelerating from about 24-26 miles per hour, 12, 13, 14 miles from port, so they can safely, easy-on-equipment-like enter at a safe port speed of less than 10 miles per hour.......and a lot of other stuff about handling big mass momentum, whether on land or on sea.

Stopped SAFELY within ΒΌ, β
, or some tiny amount of their length by a piddling little concrete pillar?
How many stopping forces were at work there?
......massive steel truss? harbor floor? crumbling concrete? dragging anchor and chain? .........Grace of God !!!!

You tell me, dustie, but from all you've told me about how massive that ship was, it should have kept going like Godzilla through New York (or was it L.A.?).

Or feathers (40 CuFt).
Like there are liquid ounces (volume, like in a soda) and weight ounces (16 in a pound of bacon).
Yea, it can be stopped, with the right kind/size of "brick wall", BEFORE the one they don't want broken (the support pier).
Thanks for asking! I have no idea, but I am eager to hear the responses from people who do understand!
