Baltimore's Francis Scott Key Bridge hit by cargo ship
- Thread starter hanimmal
- Start date
FKN crazy,the cargo ship didn't just clip the bridge,it nailed the stantion head-on for Christs sakes,what a freekin headache for the Balt. metro area,chance of survivors in vehicles or the construction crew on the bridge w/water temps. in low 40's is virtually 0 unfortunately. Video is hard to make out traffic(light at 1:30 AM thankfully) but sonar indicates vehicles underwater. Condolences for all impacted and may strength and fortitude be with all involved in rescue,clean up,and rebuilding efforts,this is going to be a long haul for the community in so many ways.
Crew is said to be Indian,foul play not believed to be a factor initially,though lots of questions are surely to be asked,like I said the ship nailed the abutment head on from the video,not a glancing blow which is suspicious. Capt/crew will surely be HEAVILY interrogated,I think when container ships go to port that someone expert in navigating the harbor boards and is in charge of navigation on ingress/egress so I have NO idea how this could go down.Time will tell as this is only hours old all I can say is I hope this is a 100% accidental mishap w/no ill intent as we already have a full plate w tensions domestically/internationally.

Coast Guard says finding survivors unlikely after Francis Scott Key Bridge collapse
Six members of a crew that was working on the bridge when the Dali, a 948-foot containership, struck the span are presumed dead.
Size of ship negated any measures meant to deflect ships, Johns Hopkins professor says
Jason Abbruzzese
The ship that hit the Francis Scott Key Bridge was big enough that any safety measures meant to try to limit the impact of a collision would have been rendered ineffective, according to Benjamin Schafer, a professor of civil and systems engineering at the nearby Johns Hopkins University.
He stressed that any failure in this situation is centered on the broader issue of maritime safety and infrastructure development.
He said that container ships like the Dali are “a different animal” when it comes to dealing with safety and collisions. "I’m afraid that this is not something that any bridge would be designed to withstand," he said. "We need to make sure this collision does not happen."
"Where’s lessons to be learned here about about how we manage our infrastructure that we need to learn quickly," he added.
Dali crew members notified authorities they lost power, governor says

Moore told reporters this morning that crew members of the Dali container ship that collided with the Key Bridge this morning had notified authorities that they had a power issue.

Think back up emergency power would save the day,UNLESS and hopefully not, foul play is involved,redundancy HAS to be built in to ALL safety systems(steering) on mammoth ships of this sort one would think.
Ukraine also responsible for "Puff Daddy" federal raids I imagine.

also, power sufficient for maintaining steerage is beyond the capacity of a plausible power backup.

Trump is predicting at his rallies -- terrible terrorist attacks on the US -- that only he can protect us from.
I'm going to say it out loud now. I predict we'll see Trump's circle of propaganda call this a terrorist attack and blame Biden. I'm going out on a limb and predict that Trump will say it at a rally. Expect a troll to say it here within a few days.

Social Media Accounts Spew Conspiracy Theories About Key Bridge Collapse
Right-wing influencers on X used the tragedy in Baltimore to boost their brands.
There’s no evidence for the DEI theory, but it’s a concept that X owner Elon Musk has himself promoted, baselessly, as an explanation for recent air travel safety snafus.
And Alex Jones, the conspiracy theorist best known for defaming the grieving parents of children who were murdered in school shootings, said the bridge collapse “looks deliberate.”

oh the twitter trolls already are.....just putting it out there....calling it a cyber terrorist attack or a black swan event.....kinda funny if you ask me...

Then again, once-reasonable people get sucked into the vortex and are lost when they hear yips from these jackals. @londonfog , for one. He lost it and stopped posting here (or maybe was banned, IDK) because he couldn't stand people pointing out facts that disproved his conspiracy theories.

Not to spread any crazy conspiracies, but I can clearly see what looks like rigged explosives or thermite going off on many different sections, right when the ship collides. Look close!

That was water shooting up between the ship and the bridge structure.
It will be an interesting analysis. I had to look.
Steering Gear System In A Ship
The efficiency of the performance of the steering gear depends on some main aspects. These basic requirements to be invariably met by all steering gears are guided by rules set by classification societies. They can be briefly outlined as follows:
- As per standard requirements, the steering gear should be capable of steering the ship from 35 degrees port to 35 degrees starboard and vice-versa with the vessel plying forwards at a steady head-on speed for maximum continuous rated shaft rpm. and summer load waterline within a time frame of a maximum of 28 seconds
- With one of the power units inoperative, the rudder shall be capable of turning 15 degrees port to 15 degrees starboard (and vice-versa) within a time frame of 1 minute with the vessel moving at half its rated maximum speed or 7 knots (whichever is greater) at summer load line.
- The major power units and the control systems are to be duplicated so that if one fails, the other can easily substitute for them as a standby.
- The steering gear system is to be provided with an additional power unit (hydraulic pump etc.) connected to the emergency power supply from the Emergency Generator, which shall be capable of turning the rudder from 15 degrees from one side to the other side within 60 seconds with the vessel moving at a maximum service speed or 7 knots, whichever is greater.
As per SOLAS requirements, all tankers of more than 10,000 GRT and all other 70,000 GRT vessels should have a safematic steering system.
Arrangements should be there to isolate the fault and continue using the steering system in an emergency. To avoid total failure of the steering system, automatic isolation and bypass valves are introduced to the system.
Under normal conditions, one pump satisfies the need for all four rams. In case of leakage, the level switch gets activated, starting the standby pump and raising the alarm.
But if a further leak persists, it initiates the bypass and isolation valve. Now the steering gear runs on 50% of its torque, isolating the faulty set of rams.
The other system, without a leak, will operate the pump, and the associated ram will move as per the desired command.
The hydraulic steering gear system is critical machinery onboard whose operation knowledge is essential for the ship’s safe navigation.

Seems that losing electrical power kills the hydraulic system and by the time they got power going again it was too late.

Grace Ocean Private Ltd
Synergy Marine Group — which manages the ship, called the Dali — confirmed the vessel hit a pillar of the bridge at about 1:30 a.m. while in control of one or more pilots, who are local specialists who help guide vessels safely into ports. The ship is owned by Grace Ocean Private Ltd.
Some more tidbits, I am starting to see a problem Captain Kirk.
Does the steering gear require to be supplied by Emergency Generator? (Emergency power supply)
- Where the rudder stock is required to be over 230 mm diameter in way of the tiller, excluding strengthening for navigation in ice, an alternative power supply should be available.
- This power shall be able to supply at least the Auxiliary steering gear and its requirements as mentioned above. If your ship doesn’t have an Auxiliary steering gear, then one of the 2 steering gears should be supplied by the emergency supply.
- Not only the steering power but also provide power to its associated control system and the rudder angle indicator.
- All of the above mentioned item should be supplied within 45 seconds, either from the emergency source of electrical power or from an independent source of power located in the steering gear compartment. This independent source of power shall be used only for this purpose.
- In every ship of 10,000 gross tonnage and upwards, the alternative power supply shall have a capacity for at least 30 minutes of continuous operation and in any other ship for at least 10 minutes.
SOLAS Requirement on steering gear system
SOLAS Requirement on steering gear system One of the critical equipment on-board! But I don’t know why most of us, especially junior engineers tend to pay

So the ship probably had a backup generator but the time for it to start, "within 45 seconds", I watched the vid and the power was off for 59 seconds. On the open seas, not a problem. But in a waterway where you have little room for error a little short.

I was talking about all these different thermite looking flashes going off, with showeres of molten sparks, smoke, and flames. Watch the vid frame by frame in these areas! Looks like it was rigged for controlled demo to me. As if it was set to go off at the same time the ship veered into the pillar at the last minute.
