Baltimore Major Bridge Collapse

Saying accident caused by a cargo ship. Have not seen a number on deaths...

'Mass Casualty Event': Baltimore Bridge Collapses, Hit by Cargo Ship

The large I-695 over the Patapsco River has collapsed after being hit by a cargo ship, sending vehicles tumbling into the water.

Jesus! I used to cross the bridge on a regular basis when I lived just south of Baltimore!

Prayers for the victims and their families!

Wow. Prayers for the victims.

Chinese container ship?

Reminds me of this one…

See historic photos from the Sunshine Skyway bridge disaster

On May 9, 1980, a freighter struck the bridge, killing 35 people in one of the worst disasters in Tampa Bay history.

Chinese container ship?

I wondered, too .
Article said Singapore.
It also said the pro navigators were on board. Sounds like technical difficulties...

Singapore-flagged.

"In a strike of blind luck, the moment the ship hits the bridge and it collapses, passing traffic appears to be very light compared to the number of cars and trucks present on the bridge just minutes earlier.

The MV Dali approaches from the north-east but approximately four minutes and 20 seconds before impact all lights aboard the ship go out, a clear indication of a total onboard loss of power. One minute and ten seconds after this visual indication that all is not well onboard some lights are restored, and they continue to turn on and off to varying degrees until the collision.

During these last minutes, the MV Dali turns sharply — particularly for a ship of its size — to starboard, putting it on course for the bridge support. From three minutes until impact until the strike a very large plume of thick, dark smoke appears to pour from the ship’s chimney, indicative of either the engine working very hard or a fire onboard. In the case of the crew being aware of the imminent disaster and attempting to prevent the collision, the volume of smoke would likely mean failed engines being restarted or — if already running after the total electrical failure — the engines being put under a high load to slow the ship down."

Terible news.

Holy shit! Prayer for everyone on that bridge!

Somewhat good news, they say 7 to 10 unaccounted for. There was a work crew on the bridge when it happened.
Could have been much worse.

Maryland's Key Bridge collapses after being struck by a container ship

Video shows the moment the vessel plowed into the Francis Scott Key Bridge in Baltimore, sending the structure crashing into the Patapsco River, shortly before 1.30am Eastern.

Maybe drop the anchor at the first power outage.
Tuesday morning quarterbacking.

Not a nautical guy, but not sure that would have stopped that sized ship in such a short distance...

Richard Hornbuckle should have bought a lottery ticket that day!!

Would a vessel of this type have a box recording data similar to an aircraft? Even modern automobiles record information.

A ship that large is like a giant sail. Even just a breath of wind will move it.
Once its moving there isn't anything stopping it short of solid ground.
It says the ship had a power outage. Maybe they couldn't drop the anchor without power?
I'd think a deckhand could activate a manual release but then again many modern ships have so few crew available.
Maybe dropping anchor in the harbor was prohibited? Underwater cables, pipelines, etc?

Yes, it's called Automatic Identification System (AIS) and it's still sitting where it hit the bridge...

It also has a Voyage Data Recorder, or VDR, (also knownn as a ship's "black box") a data recording system designed for all vessels required to comply with the IMO's International Convention SOLAS Requirements (IMO Res.A.861(20)) in order to collect data from various sensors on board the vessel. It then digitizes, compresses and stores this information in an externally mounted protective storage unit. The protective storage unit is a tamper-proof unit designed to withstand the extreme shock, impact, pressure and heat, which could be associated with a marine incident (fire, explosion, collision, sinking, etc.).

The information recorded in the unit(s) may include the following information:

• Position, date, time using GPS
• Speed log – Speed through water or speed over ground
• Gyro compass – Heading
• Radar* – As displayed or AIS data if no off-the-shelf converter available for the Radar video
• ECDIS* – A screen capture every 15 seconds and a list of navigational charts in use every 10 minutes or when a chart change occurs
• Audio from the bridge, including bridge wings
• VHF radio communications
• Echo sounder* – Depth under keel
• Main alarms* – All IMO mandatory alarms
• Hull openings* – Status of hull doors as indicated on the bridge
• Watertight & fire doors* status as indicated on the bridge
• Hull stress* – Accelerations and hull stresses
• Rudder* – Order and feedback response
• Engine/Propeller* – Order and feedback response
• Thrusters* – Status, direction, amount of thrust % or RPM
• Anemometer and weather vane* – Wind speed and direction
  
  (Data marked with * may not be recorded in S-VDR, or Simplified Voyage Data Recorder which is a lower cost simplified version VDR for small ships with only basic ship's data recorded, except Radar and Echo Sounder if data and standard interfaces available.)

Passenger ships and ships other than passenger ships of 3000 gross tonnage and upwards constructed on or after 1 July 2002 must carry VDRs to assist in accident investigations, under regulations adopted in 2000, which entered into force on 1 July 2002.

Although the primary purpose of the VDR is for accident investigation after the fact, there can be other uses of recorded data for preventive maintenance, performance efficiency monitoring, heavy weather damage analysis, accident avoidance and training purposes to improve safety and reduce running costs.

Saw this story this morning. Prayers for the families of the victims. I can't imagine being parked on that bridge, or the crew working on the bridge, having the bridge collapse, and still surviving. That's a miracle.
