The fact that the police were able to shut the bridge down 30 seconds after they were notified is truly amazing. They very likely saved multiple lives with their quick action.

[@keith6706]

It was because of the workers on the bridge. They'd set up a reduced speed zone while they were working so the police were already at both ends to enforce it.

[@brentfarvors192]

Nothing "amazing", about it...They were already there directing traffic...

[@grondhero]

I mean, I'm glad they responded that quickly and weren't taking a mandated union break, but there would be workers on each side of the bridge. Pretty sure it's standard practice across the US.

[@JohnHansknecht]

Wasn't the police. Every major bridge has a set of gates and stoplights that can be activated in a couple seconds by an operator who receives a report of an accident or, in this case, a pending accident.

[@JayneCobbsBunk]

Just for clarification, "the VDR stopped recording information" means the INPUTS to the VDR stopped sending data, not that the VDR was in anyway offline, as confirmed by the continuous BVR recording..

[@mrgrumpy771]

[@justinbailey6515]

Correction, some are equipped with internal sensors independently powered by the black box itself. Investigate the sensors available in your smart phone. Without being tethered to a car, your smartphone can track temp, air pressure, gps location, speed, etc... For something that carries billions of dollars worth of freight, I guarantee that black box has a lot more information than what we will be privy to.

[@billb3444]

As a VDR surveyor the VDR never stops recording until its internal battery is depleted. It records Serial data from sensors, video from radar/ecdis and bridge audio. When it goes to internal battery power ONLY audio is recorded. Simple as that. No mystery. Of course if someone switches off the AC, DC and internal battery it is dead. It does NOT have any internal sensors. Sensor input can be serial, analog or current interfaces. Cruise ships have hundreds of inputs. It is just a data recorder, a marinised PC with interfaces.…….the name gives it away.

@@justinbailey6515 The NTSB media person expressed her dismay that ship VDR recorders only gives some very basic information. This is not a technical problem but probably still remains because ship owners don't want it. It will expose them to a higher level of accountability.

[@GrahamPearce-ib9om]

It is probably more correct to say “During the blackout period the VDR recorded that there was no sensor data being received.” Easy to explain as you said as there wasn’t any sensor data.

[@wathaet1386]

Precisely. Anyone with experience operating recording devices understands that when the equipment feeding your recorder lose power you are still recording, but get a blacked out signal with only the very low level background noise of the system noise floor.

[@Sagewyn]

​@@wathaet1386 so losing power means , losing electrical power in this context? this due to a problem with electricity supply to those devices which transmit ? guess we don't know why electic power ceased? ships engines ceased? problem in wiring etc?? It was then restored. via backup generator? or restarting engines?

[@adrianthoroughgood1191]

​@@Sagewynpower means elecricty supply. This comes from separate Diesel generators. There should have been 2 of these running in these circumstances. All power was lost. Either both generators stopped running, or something caused the breakers (fuse box) to trip off. With no power nothing on the ship is working, except for things that have their own backup battery, like the VDR. The steering cannot work without power. The engine cannot run without power. The emergency backup generator started up automatically but it took about a minute for things to come back on. The steering can be operated on emergency power but it takes longer to turn the rudder than when full power is running. The problem was that the one minute power cut happened at just the wrong moment, and by the time they were able to turn the rudder away from the bridge it was too late to avoid the collision.

[@gervaisbilodeau8465]

@@adrianthoroughgood1191 Did they reverse the propeller action? When a ship propulsion goes astern, the rudder becomes useless.

[@adrianthoroughgood1191]

@@gervaisbilodeau8465 Some people think they did, because of the black smoke and because the speed dropped a bit. But the smoke may have been from the generators starting up. The slow down might have been due to not running forward and the anchor. We won't know for sure until the NTSB release more info from the VDR. Rudder depends on water flow over it. How much you lose in reverse depends on rudder and propeller configuration. Since the ship was still moving through the water quickly there may have still been a lot of water flowing over the rudder, even if the engine was running in reverse.

[@sunilrpieris7045]

I am an ex Marine Engineer, sailed on different types of vessels inclusive Cape size bulk carriers. I also involved in ship building for about 5 years and now retired. To my knowledge when a blackout experienced on board a cargo ship, either the emergency generator or standby main Auxiliary engine should start within 30 seconds or if a battery bank is equipped, system should start and power must be stored within 45 seconds as per SOLAS. At the same time all emergency equipments (ie: Navigation lights, Radio equipments, VDR, emergency lighting in ECR, Bridge, Steering room and other essentials) must be operative. But I do not see any lights switched on this ship after the first or second blackout. Ships are equipped with emergency manuring system and they may have not attempted same. On the other hand ship was heading through a narrow channel without tug assistance causing this disaster which could have saved billions of dollars.

[@tedmoss]

You seem to be a nice person, so I'll make some changes to your statement. replace manuring with maneuvering, we have enough manure going around on the internet already. Power must be restored. Maintenance is the most likely culprit here, but I get the feeling that more training in emergency procedures would be a good idea. These comments are from my own experience. What I see from my seat 2,000 miles away is a chinese fire drill. We speculated that they tried to go in reverse, but you can't really tell from my armchair.

[@georgiarasmussen8343]

I have the same questions you do, but as a farmer-aspiring-to-marine-engineer, I have to ask how an "emergency manuring system" works.

[@gigglingdingo]

Yes your solas system analysis is correct - in the video when you see the first black out ( all Nav lights visible [ ie the two masthead and green starboard light) and the forecastle flood light and deckacessway lights go off ( a dead ship - indicating a main switchboard trip), then some lights comes back on , it is the Navigating lights ( mastheads and side light) and some deck acessway lights (ie emergency deck lighting) but the Forecastle flood light does not come on - I am sure as per solas this is Emergency Generator kicking in and the Emergency Systems repowering. You then see the start of black smoke out the funnel ( Rich air fuel mix) on Main start, then you see the Forecastle Flood light come back on ( main power re established), during the second black out - the Navigation Lights stay on but the Flood light goes off ( indicating the Main switch tripped again, but the emergency circuit was still running. Noticeably the Black Smoke is still belching so the main engine didn't stop during the second blackout - and the continued belching of black smoke suggests Load on the Engine. I am pretty sure the First black out was a Main Switchboard trip causing the Maine Engine auxiliaries (lubrication & fuel pumps) to stop causing the main engine EMS to trip a safety shut down. But the second Blackout looks like another Main Switchboard Trip - that was caught before it triggered another Engine Trip Shutdown - what would cause the Main switchboard to trip without seeing the EMS alarm logs I am not Sure. ( my old ship Sulzers were temperamental at time but not as computer managed so our Ginger Beers had to do run around the Engine room.)

As a retired Electronic Design Splst, I have to make a note that most sensors are not dependent on any power other than the power of the data recorder that they are connected to. Some sensors send their own power, because of temperature differences as a thermocouple or a solar cell for light or darkness. Any sensor would NEVER be dependent upon ships general power, but the power of the Data Recorder. To disable a sensor, a wire must be intentionally severed. Hmm, then it must be reconnected to resume recording? How does that happen while the VDR is still working? I think we're never going to know the real story; I just wish Paul Harvey were here to give us "The Rest of the Story."

Without the main switchboard or the E Buss powered up you'll still be monitoring remote sensors since they are powered by the UPS. They should also pull the alarms from the engine management system of all the auxillary DG's and the EDG. They should get the alarm logs from each main switch control on the main switchboard and the EBus including the buss-tie breaker.

The Dali has 4 main generators = emergency generator.. If you run three on line the 4th main generator should be set to stand- by. The emergency generator came on which means that the 4th generator was unavailable or was not on stand-by. To lose three generators you have to have a catastrophic failure , the failure on one generator should cause the other generator to stop. If that causes a blackout then the 4th generator should start followed by the remaining generator that did not cause the initial blackout coming on automatically within a minute.. I was in Hyundai. Heavy Industries shipyard when the Dali was built. The vessel I was commissioning was not accepted on hire. It had one generator fail on a blackout test, failed to restart due to a fault the other generators unaffected.

If shipping is anything like trucking the person that signed off on the pre-trip inspection is responsible for this catastrophe.

Shipping is not quite like China of Responsibility in Trucking loads. For example in relation the ship operations ( nb: not the port operations), the ship Chareterer ( leaser) determines the port an cargo and supplies fuel and other necessities. Before departure, the Duty Engineer prepares the Main engine ( Fuel, lubirciation, Engine temp, Systems line up) - take about an hour, a junior engineer prepares the Generators, both under supervision of the 1st engineer, the Duty Deck officer ( often the 3rd mate deck officer) does the pre departure bridge equipment checks ( including testing the engine by kicking it ahead and astern with the engine room and the helm), the second officer usually sets up the Navigations system and passage route, the Chief officer ( aka 1st mate) completes Ballasting for drafts , cargo ops and lashing supervision( done with the Bosun and Deck crew checking the stevedore fitted lashings) and stability calculations for departure/ the voyage., The Chief Engineer supervises the Engine room preparedness and the Master supervises the Deck officer preparations and is ultimately responsible for all Deck, Engineers and Crew.

Here's what happened. When the power went down the pilot lost steerage as it is a fly by wire system. He then called for full astern. That is the plume of black smoke from the funnel. That was a mistake. When the ship engaged full astern it began what we call a prop walk. The stern moves to port and the bow moves to starboard. There was too much way on the ship to stop before the bridge. It was doing 8kts prior to the power outage and 6kts when it hit.

While this is a sensational story and is bound to have all sorts of theories and lots of blame, it was the conclusion of a series of unfortunate mechanical issues and not enough time to correct them. My initial thoughts were that tugs should remain with the vessel until it passed under the bridge but, if it is normal to be at 8+ knots at that point, tugs would not be very effective at correcting the heading in time either. It is fortunate that traffic was light at the time and that the call was made to prevent access to the bridge before the crash!

[@gigglingdingo]

FyI the legal argument about contribution of blame/ Liability based on the chain of contributory events are likely to be at least: 1) the ship owner's Insurer for the initial Back Out cause, 2) The responsible authority for the bridge protection barriers ( they were ineffective/ an out of date standard), 3) the Port authority - for Port procedures concerning when tug are required and port speeds, 4) whether the Pilots actions where with out fault ( while he did a lot of good, any Astern order will be heavily argued as causing the swing starboard - when possibly doing nothing or kicking the engine ahead when engine came back on would have got the Ship clear under the bridge.) Mearsk as charterer will have some protections under contract but the ship owners( insurers) will argue that because of the port procedures and poor standard of limited bridge barrier protection the port was unsafe for the ship - so Maerske may have to indemnify the Ship owner's ( insurance) losses.

[@robertpullis]

Thanks for clearing up how the black box wasn’t shut off. What is bewildering to me as a former airline pilot is how ships don’t have to have a battery backup system capable of powering the bridge controls and powering a hydraulic pump that moves the rudder accordingly. Am I wrong? How can the bridge sensors not have a battery backup if only good for 60 minutes (long enough to steer toward safety while buying time to drop anchor and get tug assistance, etc.). While airliners have redundant electrical systems, they also have an emergency backup battery as well as a deployable ram air turban that can create electricity from the airflow outside the aircraft fuselage. While I’m not familiar with how much electricity can be produced from deploying a “water turbine” into only 8 mph of water flow, it seams odd that a huge ship could lose the ability for its electrical steering commands to fail to reach the rudder (and the black box). Perhaps we will see a new regulation requiring backup batteries to support steering. As on airplanes, the backup system should prioritize things like cutting off the electricity going to the galley, but not assuring steering even during a a failure of all generators seems to be a major design flaw. I suspect a small army of lawyers will be leasing additional office space in Baltimore soon. Please correct me if I’m mistaken. Thanks again for a great video!

[@eSysmanSuperYachts]

The bridge of the ship does have a battery backup in this instance but it appears from what we know that it failed to operate, based on the fact the VDR went right to internal battery when they blacked out. The ship has an emergency generator similar to the aircraft ground generator you use whilst in airports but it starts up after detecting a blackout and takes up to 45 seconds to kick in (45 seconds is mandated by IMO)

[@tomarmstrong5244]

Turbocharger lag as the engine is started astern. The turbocharger cannot get enough air into the engine for combustion and unburnt carbon is emitted from the funnel. Also the propeller would have slipped for a while and in the time available there was no chance of significantly slowing the ship.

That clears up some of my questions. I remember way back when I was in the Navy. I was a radarman on board a ship. When the pilot came on board the old man always paced the deck. Some pilots were good to deal with and he liked that. Then there were the in-control pilots, those guys he detested and paced furiously. You are correct, the old man is ultimately responsible for his command, pilot or no pilot.

It would be relatively expensive to upgrade every sensor on a large vessel so that each one continues to operate during a central power failure. Then theres the separate issue of having to periodically check and maintain every sensor, e.g. changing batteries, which would become fairly burdensome. So this will continue to remain an issue in future incidents.

[@RobertHullihen-xs4hw]

My thought is this, if as said a power outage on the ship, that means the rudder of the ship can't be moved, it stays in the position that it's in, you see the video the ship without question is heading towards the opening between the two bridge supports, but not too soon after the ship makes an abrupt turn that causes contact with the bridge support. As it has been said an anchor was dropped on the right side of the ship, would you not make an all out effort to keep the ship in the direction its going to prevent any sudden turns? The ship was on a perfect line to go between the bridge supports. It's that abrupt turn(yes the anchor was dropped) maybe I'm wrong but I don't think the abrupt turn should have happened.

[@chrisjohnson6765]

There are various reasons it could happen with the use of a rudder, but the turn was only 11 degrees according to AIS…

[@grahamcourt1914]

That anchor would drag thru river mud it would never have had enough grab to turn a ship,loaded,of that size so quickly. The intermittant power seems to be solely for the purpose of powering up to ensure bridge support contact. The black smoke belching out is indicative of max power being applied. If that power was applied to astern direction the water cavitation would be visibly obvious. The simple answer is usually the right one and the simple answer is it rammed that bridge on purpose.

[@gigglingdingo]

The voice recording on the VDR and data recording will have captured the actual commands ordered and helmsman confirmed - a technique that is sometimes used to help slow a ship is called Rudder Cycling ( 20 degrees to port (or hard to Port) and immediately 20 degrees to Starboard ( or Hard to Starboard)) - The aim being that the drag caused by the increasing the rudder face in to the water flowing past the rudder slows the ship without actually changing the heading significantly - That is a method but when so close to the bridge I suspect the NTSB was loose in their words and the pilot might had asked the Helms man to steer a course to steer( ie 141 degrees) so as to keep the bow up wind and to left of the mid channel. The NTSB's Language is likely referring to the back and forth about whether the ship was responding to Helm ( ie was the helmsman having to apply more and more rudder to keep the ordered heading.

[@wayneo7220]

@@gigglingdingo Thanks. That's the best explanation I've heard so far and makes sense. I guess the power going out when the rudder was to starboard while cycling is what caused it to veer right. The ship was in the channel when the power went out, so I can't help wondering if it was even necessary to scrub off speed cycling the rudder at all, especially given the short distance to the bridge and being very unlikely to have been able to stop it before it reached it. At least coast under the bridge first, then once clear, try to stop the ship where they had more room.

So... What exactly were the rudder commands by the pilot at 1:26 when power first came back? Because on the video it is clearly seen that at that precise time the ship started turning right towards the pillar of the bridge (prior to 1:26, during blackout, the ship was clearly going straight and would have missed the pillar). So, did the pilot give the command to steer right? Or did the bridge crew make a mistake and turned right when the pilot made a command to turn left? Or did the ship magically start turning right on its own?

Thank you E Sysman, Replying to my comment regarding the port anchor issue. Apparently the order to let go the port anchor was given as recorded by the VDR, unfortunately it was carried out in delayed time as shown by video recordings, access to the port windlass is still available after impact. The video shows clearly that access to the stbd windlass is no longer available after impact. A diving operation near the port bow of the ship will reveal the exact position on the seabed or below if embedded in the mud, the NTSB should insist on such inspection, if they have not already done so. I am also fully aware that the anchor would not stop the ship on time, but as you know from all safety management and emergency response manuals in place nowadays on all merchant vessels, it is our duty as ship masters and pilots to take emergency actions immediately, for time is not our friend on such occasions. In the VDR audio recordings where exactly is the audible order from the pilot regarding “hard a port” to the helmsman if in manual steering as it should be and the acknowledged order by the man at the wheel. Where.?… Where in the VDR are the orders from the Captain or Pilot for engines “Full Astern” and the bridge response to such an order. In the previous video it does not show the wake near the stern to indicate a reverse thrust prior to impact. May I take a moment to congratulate you on your professional reporting on this matter. I feel for my fellow seafarers as we all do not wish anything like this to happen to anyone. Thank you.

The wind was reported. It was negligible. River current was irelivant unless it was running across the river.

Neither of these two conditions would explain a hard turn to starboard especially as the reports say that the port anchor was dropped and the order was given of a hard to port turn was given by the pilot.

Unless you are telling us that in the case of lost power, the rudder swings to extreme side lock position. Something that would require massive power to push the rudder against the tonnage of water flowing past it while it was going straight at 8 knots. Pull the other one! This was a deliberate sabotage.

Jesus, did you watch the video? The "black box" never stopped recording, it stopped receiving the information it was supposed to. It kept running through a backup energy source. Yes, no ship power means no power to the rudder, however, it would depend on where the rudder was pointed when the ship lost power. The turn has no definite explanation, but many say the crew pulled a crash astern maneuver in an effort to slow the ship by fully reversing it. This is possibly justified by the black smoke and the fact the ship turned starboard. The ship's bow turned right and the rear turned left. This is normal when you try to reverse the ship and you don't have rudder control to counteract it. I do not believe it was a sabotage. There was quick action by police and there were distress calls.

Thank you for yet another outstanding update. For my opinion, I shall remain silent until more information comes out.

[@anthonymiller7992]

I have a theory The port side " front " anchor was dropped. Question 1: what was dropped in the rear if any? Q2, what was the wind AND current at the time. Q3, what was the rudder inputs and was the propeller turning and which direction? Theory is this, front port anchor drops w/ nothing from the reer. Rudder commands with no proppeller gives minimal reaction because of the current. The wind and the current speed and ship speed with drag in the front causes the reer to begin to swing out to the left but the current of the water begins to push the ship in the easiest path ( to the right ) with the help of the wind. Again just a theory but it would have to be a perfect storm. When in actuality due to the speed and distance the pilot should have made no change of course untill they had solid propulsion because your too close ( 500 m or so ) to adjust if things doesn't go the way you want. Nothing from the front should have been dropped only rear anchors Just a thought with a lot of un knowns...
