RECAP: How did The Dali Ship crash into Francis Scott Key Bridge?

new questions are unfolding for

investigators now getting their first

look inside the crippled MV Dolly cargo

ship the latest goal is piecing together

the final frantic moments on board the

ship as it careened helplessly out of

control and into Baltimore's Key Bridge

causing it to collapse six contractors

doing pothole repair are now presumed

dead our thoughts and prayers are with

their loved ones whose lives are never

going to be the same the latest

Discovery the Do's Black Box known as a

voyage data recorder the dollies has

been recovered and is being analyzed by

the national Transportation safety board

we've sent that back to our lab to

evaluate and begin to develop a timeline

of events that led up to the strike on

the bridge uh and we hope to have that

information to share with the public

later today the recorder captures data

like heading speed and water depth as

well as the condition of the engines

thrusters and Rudder but also audio on

the ship's bridge where the crew called

for dropping anchor in a last ditch

emergency maneuver the pilot made all of

the right calls in a timely manner but

the uh the voice recorder will confirm

that and I think this

investigation uh all of the pieces are

in place uh to have a successful uh you

know conclusion the the real challenge

will be how do you prevent this from

happening again the search for the

missing Wednesday h hamstrung by poor

weather and heavy rain deemed too

dangerous to continue among the jagged

pieces of the bridge in the mury pamsco

river you could have 20 parts that are

suddenly going to change position diver

could be dead in a matter of seconds and

he wouldn't even know it so we are on a

cargo ship about the same size as the

dolly but we are navigating San

Francisco Harbor in this case uh this is

all a simulation but we have a real

captain captain organ mcmanis who is

going to walk us through possibly what

could have happened in a total blackout

situation as you call it aboard the

dolly yes so we have the uh the a Cadet

simulating the ma on watch we have

another Cadet on the helm uh go left 15

please and and the dolly would have lost

both propulsion and steering at a full

blackout they would have lost everything

full blackout you call it right so we

could run the blackout right now from

the control room

so there we go alarms will start going

off on The Bridge start getting alarms

the ma on watch is going to try to

figure out what the alarm is the engine

room is now calling to tell us what's

going on bridge made on Watch and in

this situation where you can see the

pylon coming and you know it is disaster

can you can you drop the anchor what are

what are the you guys train for these

scenarios we're going to you're going to

try to do everything you can to stop

from hitting it whether it's running the

engine full of stern to take the speed

off we've already come down to almost

stopped in the water now um and then

we'd be letting the anchors out if we

couldn't get the speed off the vessel

you can lower both anchors down and have

them drag or catch along the bottom to

create resistance to slow the ship down

but for that to work you need time and

you need distance the captain's going to

be dealing with the engine room and

getting on the phone and figuring out

what's going on so they would be going

over grab room right would be the I I

think it that's where the real chaos

that's where the real chaos is so now if

they call back and say we power the

first thing we're going to do is then go

emergency full of stern to try to stop

it looks like they do establish power

just before they hit the Pilon they hit

the bridge Billow of smoke comes out

they start trying to go a Stern get the

speed off this must have been high

anxiety at this point on the bridge

trying to deal with this oh and

Incredibly stressful watching that first

video clip when I saw the total power go

out on the ship I knew there was a major

problem going on so one other thing we

wanted to show you was what it would

look like at night we shot the

simulation during the day so we could

see everything but this is much more

what it would have looked like for the

dolly in Baltimore haror it complicates

things at night I take it it does you

have um you need the bridge dark so you

could see the lights outside but you

also have ambient light from the skyline

or The Terminal coming in it also uh in

darkness you lose some depth perception

which makes it a little challenging to

actually judge your distances as well so

it and it complicates moving around the

bridge at night and this is you teach at

State University New York Maritime

College I take it what happened in

Baltimore Harbor will be studied for

decades it will it'll become one of

those tragic accidents that we take

lessons learned from and then we apply

them to what we're teaching the students

of what to do in an emergency on the

bridge of a ship behemoths of the sea

International Trade depends on Mammoth

vessels like this container ships the

kind that brought down Baltimore's

Francis Scott Key Bridge in an instant

up close you realize just how huge these

ships really are this container ship

here it's a bit larger than the dolly

that is the Singaporean owned container

ship that brought down the bridge in

Baltimore this week the dolly was built

in 2015 and is 300 M or 984 ft long

capable of carrying up to 10,000 20t

shipping container ERS for a dizzying

variety of commercial interests when you

look at international shipping this is

this is kind of the typical case here's

a Singapore flag vessel with a Singapore

company uh leasing The Vessel to a

Danish company the insurance for the

cargo is British the classification

society that observes The Vessel as

Japanese there have been three deadly

incidents recorded aboard ships managed

by the do's operator Synergy Maritime in

the last 6 years an accident with a ship

elevator killed a crew member in

Australia in 2018 in 2019 an officer

went missing after having likely Fallen

overboard in Singapore and last year a

collision between a Synergy Maritime

tanker and a dredging ship killed at

least one sailor meanwhile in June of

2023 Chilean authorities briefly held

the dolly reporting a deficiency for

unreadable pressure gauges related to

propulsion and auxiliary Machinery this

is what you want you want you know

inspectors to go on board and find

issues and are they corrected now the

bigger issue here is going to be did

this ship have certain violations that

were causing it to you know indicate a

uh kind of a habitual problem Synergy

says it's cooperating with us

investigators and a spokesman tells CNN

it would be inappropriate to discuss any

previous incidents at this time

Singaporean transport officials say the

doll's crew reported a momentary loss of

propulsion shortly before it slammed

into the bridge in Baltimore look at the

size of this container ship next to Hong

Kong's stone cutter bridge at the time

the Francis Scott Key bridge was

constructed in the late' 70s container

ships like this simply didn't exist they

were not being built at that size and

scale in those days just last month

China witnessed a deadly cargo ship

Collision iion with a bridge on the

Pearl River in the city of Guang Joo at

least five people died as Vehicles

plunged off the stretch of collapsed

Bridge authorities initially blamed the

crew for the accident Global Supply

chains rely on these enormous ships to

move Goods around the world the

Baltimore bridge disaster May Force some

to reconsider the size of these ships

and the potential damage they can do

when things go wrong Ivan Watson CNN in

the Port of Hong

Kong the Port of Baltimore is one of the

biggest economic engines for the state

it it the impact alone is $191 million a

day when that shipping channel is closed

15,000 jobs depend directly on the Port

of Baltimore with more than 100,000

other jobs linked to it Scott Cowan

represents a couple thousand of those

workers so this being blocked is would

you say it's a worst case scenario oh

it's catastrophic for us the port

handles B millions of dollars worth of

foreign cargo each year that includes

more cars and trucks than any other Us

Port it also manages heavy farm

machinery imported sugar and coal

exports the extent of the impact hinges

on how long the channel is closed there

is a quite a few ships that are stuck in

the harbor there's a bunch of them down

at the Anchorage and some ships have

been diverted to other ports meantime

several cruise lines have to reroute

operations out of Baltimore it was so

surreal and you know I watched in horror

like I'm sure everyone else did the

Carnival Legend left on Sunday set to

return in one week Carnival now

temporarily moving operations to Norfolk

AAA manager and former police officer

Regina Ali is on board we know that uh

the cruising industry will be impacted

out of Baltimore it's significant if the

channel isn't cleared by the end of next

week Cowan says things could take a turn

for the worse we lost lives and that's

what matters more than anybody's

paycheck but again the Maryland the

whole State of Maryland's economy is

hinged on the Port of

Baltimore
