Sourcing, coordinating, and positioning the necessary equipment will take at least that long. I give it 6 weeks.

This is GD. Everything is a malicious and probably extremely elaborate conspiracy done by people who for whatever reason can never be touched except by the grim reaper himself.

The simple explanation is the ship hit the bridge and the bridge fell.  
Is that simple enough for you.

I'm not a sailor.  But I used to work for a guy who was a major player in the inter-modal shipping business.  We used to deal with Baltimore a wee bit.  It's always been my understanding that some of those container ships are just a stiff breeze and a few wraps of duct tape away from something very bad happening at any second.  The owners run the ships mercilessly and the crews aren't exactly well trained or well rested.  It's a recipe for disaster, especially when you're trying to hold down shipping cost.  My money is on mechanical failure due to deferred maintenance.  A sign of things to come.  

It's a huge hit to the port and to the city.  And the loss of life was probably avoidable.  I seriously doubt the shipper will ever be held financially liable for this cost.

8/10. Comments like these are what makes GD great.

I for one welcome our new Michelle Obama bridge.

What about vehicle traffic? How important was that bridge for commuters?

Flood tides happen, the tide there is about 2 feet. There is a river and a creek that both empty there. The river is before the bridge ( leaving ) and the creek is after. Neither make much current. The tidal current is less than a knot on average, but can hit 2 or 3 if the wind helps back it up. @jellyBelly

Nah.  Drag the shit out of the main channel.

It'll be months until it's cleaned up, but I bet they focus on opening up a lane.

Doubt. Highly doubt.

That's a big bridge.  It'll take more than two weeks just to mobilize the gear to do it, and that's if it's on the east coast already, gulf will take longer.

The ship is basically pinned in place by a span right now.  They'll have to lift it off to prevent sinking the ship.  After they collect whatever evidence they want. That shit isn't going anywhere soon.

I'm not kidding about a company like Mammoet, there are only a few that have the resources and skill to tackle this in the short term.

Just write the check. Make it cost plus and get it done.  This is an actual situation where government can act to cut the bullshit red tape and just make it happen.

And it was made in 1972 before there were ships with this kind of tonnage.

In 1972 the largest container ship was the LiverPool Bay 2961 TEU.

The Dali was 9900 TEU. So over 3 times the cargo capacity and probably 3 times the size and weight.

I doubt those concrete bollards produced in 1972 had that size of a ship ( which is a medium size ship today ) in mind during the design and construction.

Am I interpreting that correctly that the ship cleared the bridge, then lost power and hit the pylon stern first after reversing?

I watched the video earlier this morning. You can see the ship lose all power twice before impact.  

There may have not been any wind, however, currents can be a bitch in itself.

I used to watch the Hyundai boats come in Puget Sound.  Nothing like seeing a freak current drag a ship and 4 tugs around like a dog with a rope toy.

Just dispatched some of our light towers at the behest of certain agencies and based on the other standby requests the problem is going to be flooding too many resources without a plan.

I'm no marine engineer but have significant experience working with vessel steering systems on the control end.

The way it works is vessels of this size typically have two large hydraulic steering pumps that are running at all times. At the steering stand or bridge console pump 1 or 2 can be selected very quickly.

The pumps themselves should be powered by either a primary bus or emergency bus. Which bus is feeding the pumps depends on the state of the ship's DGs but it is pretty rare for all of these systems to fail.

What I predict probably happened was a failure of one of the transfer breakers shortly after departure as the engineers may have switched from a smaller auxiliary generator (which may be used in port due to smaller demand) to one of the larger primary DGs.

Typically two DGs will be running at any given point in time with only one actively providing power to main buses, and all that has to happen from a mechanical failure is for the transfer breaker to switch which DG is handling the load to the DG currently on standby.

The failure occurred faster than the emergency DG could be brought up and supply transferred to the emergency bus.

Does it happen often? No. But it does happen. It happened at the worst possible time for this ship.

A steering stand failure could be a possibility as well, but a failure at the stand is not that common.

In any case, the ship is sinking so this information will have to be collected from the VDR capsule. The VDR will log a significant amount of events but unfortunately it will likely not log automation system alarm history (showing what plant failures may have occurred) but will log things such as rudder angle - not all that useful as we know the rudder angle was not so good.

Some automation systems have their own separate VDR (not all that commonly used in my experience) or report events real time over the vessel internet connection.  We'll have to wait and see. Most of the automation systems out of various smaller Asian countries suck in this regard.

Expect that here on out a tug escort will be deemed required for all vessels departing Baltimore until they have cleared the (soon to be new) bridge.

Reading comprehension — get better at it.

Reread what I posted.

That's EXACLY what I said.

In before James Biden gets the contract!

ETA: I don't know if Mammoet has a marine division, but they are definitely the go to heavy lift/heavy transport on dry land

Yes yes yes, sorry I'm semi tarded today.  

It's .5 psi, half a million pounds of force cumulative.

https://gcaptain.com/baltimore-bridge-collapse-what-we-know-so-fart/

This site is going to have some of the better analysis.

Uh, yes, the bridge in my brain has re-connected.

Honestly shocked it doesn't conclude by mentioning minorities and LGBT will be the most severely impacted by this tragedy

Crew requirements for a ship like that?

Uhh, one I suppose.

So… it WAS terrorism!

I'm watching video now from a helicopter and it looks like the rudder is centered.

Hard reverse, assuming that it's a right hand rotation prop, would have kicked the stern to port without any rudder input.

It's called Kinetic Energy and for a ship this size, I'd estimate it's measured in Kilotons. Just like an atom bomb.

Stand on top a can of soda. no problem right, now stand on the SIDE of the same can.

They have an offshore division but yeah there are others.  SMIT...is a big one.  

It's got to be some company like that,  the scale is hard to grasp from pictures.

Not sure if it's the same incident, but a 1000 footer was about to depart Duluth harbor and lost control/power/something as it made its way to the aerial lift bridge canal. Rather than risking damage to the canal and causing an obstruction, it managed to plow into the shore in an area devoid of anything structural, keeping the harbor unblocked. A bad situation handled in about the best way possible. Not the same options available in this case, unfortunately.

Interesting.......

The hard right after it passed the protective pier(?) seems odd. Unless it just looks that way from the viewpoint of the camera....

ETA: Potentially answered:

Channel, my guess is a month, but could be two weeks. I see them doing very little for two weeks as they investigate and recover the any cars and bodies. The cant go pulling pieces if the bridge out with divers in the water. So a week or two for that minimum. Then they can probably get the channel clear in a week or two. There will be some down times when the divers go back in as they take pieces of the bridge out and fine another car.

Yes the bridge could be a year, but I would guess two. Its not like they have steel just laying around set up for bridges, that sort of thing normally takes years of planning and prep

In before Russians colluded with ISIS to take down the bridge as revenge for last weeks Moscow attack

Damn!

That’s a hell of a big ship. That’s what they get for running nut coal in it.


RIP to the lost. Good thing it happened at night, could have been a lot worse if it was bumper to bumper traffic.

They probably have stuff on the way now. They will be remarkably quick opening the port.

You forgot about Trump!

wow, we knew that hours ago

George Floyd memorial bridge

Indeed.  When I first watched it I didn't notice the lights turning on and off.  All I noticed was him rolling coal which I took as giving her all she had in forward.

Shades of the USS South Dakota losing all power while engaged with the Japanese fleet.  The entire ship went dark.

Heerema, etc...  Of course with our luck, those vessels are probably off in the Persian Gulf or SE Asia right now.  But something in that class.  Really big lifts.

OTC was a fun trade show to attend as a student trying to get into O&G law.  Didn't happen, but there's some really neat tech and awfully smart people working offshore.

Attached File

Can't blame people for suspecting a potential for terrorism:

- World-wide social/economic strife.

- Weak administration/aggressive foreign powers ramping up rhetoric.

- Recent warning by nationwide sheriff's association that terror-risk is higher than pre-9/11.

- Nobody trusts nobody these days, due to decades of deliberate lies/spin/gaslighting/politics.

- Ship veers directly into pylon of bridge at a major port, blocking channel. Massive economic consequences projected.


If it was just an accident, it damn sure fit the terror profile by an amazing culmination of bad circumstances.

Can u guys please stop with the bullshit!

Save it for your own your country hates you russian propaganda thread.
