A containership collided with a bridge in Baltimore during the night, with the mile-long bridge instantly collapsing into the river below, taking several vehicles with it.
It is too early to assess casualties, but they are thought to be quite high.
The bridge is a critical part of the highway from the northeastern states of America to New York, and Baltimore is America`s 8th largest port. The port will likely be closed to shipping for up to a year as work will be required to salvage the bridge from the water before the shipping channel can reopen.

Watched the online collapse with Mrs BPP this morning and we were both shocked and horrified .. All those poor souls .. what must have been going through their minds as the bridge started to fold .. As jake pointed out very quickly .. How did the ship miss the huge middle arch ..
A lot of answers required

It looks like the ship lost all power which includes steering prior to the collision.
In these cases it can take a large ship a mile or more to come to a halt.
As tragic as it was, it would have been devastating had it happened during the day with 10 times the traffic.

Would imagine the build of the bridge was to support the weight of traffic, never anticipating a side impact...
Awful stuff

Did the ship not hit one of the main foundations?
Interestingly the Forth Road Bridge had further protective measures constructed some years ago!

Not a lot you can do after a ship loses propulsion unfortunately.
Steerage is significantly reduced if not effectively gone if your screw isn`t turning .
Terrible tragedy.

Sleepy Joe?! Making fun of a guy with a speech impediment due to a medical condition, yet doing a great job.
Do you prefer the guy that`s selling Bibles to pay his legal fees for fraud, rape and shutting up his porn star bit on the side?

Trump is little better in that regard. Called his wife Mercedes recently and has often referred to Biden as Obama. Also let`s never forget Trump`s nonsensical ramblings about using disinfectant and ultraviolet light inside the human body to kill corona virus.

Lol. We all do that. We aren`t all in the public eye 24/7, though.
He has a speech impediment. He suffered two brain aneurysms, which affects his speech and possibly memory, but not his intelligence or wisdom.
Trump, on the other hand, is well below average.
He is an expert grifter, though, and as long as fascists bigots and conspiracy theorists, or mega rich tax cut junkies support him, he will be successful at it.
He knows how to play his cult followers, and they just keep giving.
Grifting is the only business he has that turns a profit. He bankrupted everything else, and Truth Social is next.

They`re both not immune to these kind of errors - at least Biden doesn`t go off on incoherent rambles despite his occasional stammer.
Think it was Nikki Haley.
Shocking disaster - thankfully at night tho or would have been far far worse.
RIP to the victims.

Easier said than done. Apparently, there is a huge issue with the pages sticking together.
His worst grift yet. Guaranteed to lose a lot of support with this one.

Looks like the ship lost power, then generators kicked in as you see smoke coming from the back then looses power again for a short time. Would the sudden movement towards the bridge be caused by the captain dropping the anchor to try and slow it down?

I read that they had tried to deploy the anchor but it is unknown if this was successful.
Also read that the movement to the right was most likely caused by trying to suddenly go into full reverse thrust which is known to effect the rudder in a way that would cause this to happen.

Lots of factors in play here.
I don`t know if she had a clockwise rotating screw or anti clockwise.
Or indeed if she had one screw or two.
Maybe the vessel had variable pitch screw/s.
All react differently while going astern but typically a ship will have a tendency to kick the bow to port or starboard when going astern.

Generally, fixed-pitch propellers rotate clockwise. The odds are that the Dali would have had one fixed-pitch propeller - one is enough for standard container vessels operating up to 22 knots. Variable-pitch propellers tend to be fitted on vessels requiring high manoeuvrability, such as cruise ships, ferries or tugs.
When a vessel with a fixed-pitch propeller moves forward, and the steering wheel is left midships, a predictable behaviour occurs. The bow tends to drift to the left (port). Conversely, when the vessel moves astern, the bow drifts to the right (starboard). This sideways action, known as transverse thrust, is a reliable characteristic of vessels with fixed-pitch propellers.
The smoke you see coming from the funnel was likely created when the Dali went full astern. It also coincides with the sharp turn to starboard the vessel took. This may have been accentuated by the fact that the vessel was still moving forward at about 7 knots.

Just the man to answer this question then! How much can anchor slow down a ship of the size that hit that bridge? In comparison to the size of the ships they are anchoring these days they look inconsequential.

It is not the anchor but the weight of the chain that holds a vessel in place when the anchor is dropped, TOWK. As a rule of thumb, the length of the chain let out is approximately seven times the depth of water. The material on the sea bed will determine how effectively the anchor flukes grip the ground. Mud is best, while a stony sea bed is worst.
Given the haste with which events developed aboard the Dali, it is a wonder that they managed to drop the anchor at all. However, the ship was still moving forward at speed when it hit the bridge, suggesting the anchor had dragged and not gripped the sea floor.
Doubtless, all the details will come out in the inquiry.

Ah ... I was a mere deckie , sometimes boatswain with occasional days as skipper on tugs if we were short of crew.
Twin screw tugs mostly.
