Ex machinist mate of a Ohio class sub here. When you lose hydraulic power, the pressure in the rudder control cylinder will start trying to equalize. This could push our pull the rudder a few degrees in a certain direction. Also, the hydraulic control pilot valve would have stopped where ever the last position it was when the hydraulic accumulators went dry. It's possible the helmsman was inputting a little right rudder to hold heading when the power went out, because you can't hold a heading without steering back and forth from left and right. In the Navy, they have us +/- 5 degrees of rudder to hold heading without having to ask permission. The slower you go, the greater change in rudder is required to hold a heading. So for all we know, the rudder could of been stuck at Right 5 to 10 degrees there whole time there power is out. Which would help explain the veering into the bridge.
Thanks for sharing. That's interesting to know about ships steering. Frankly, most of us know little, if anything, about how large ships work.
You have to steer left and right to hold a heading in the center.
Ok, but isn't that more applicable out in the open sea?
This is in a protected bay with no wind and no current to speak of.
It's hard to envision steering a giant ship right and left in these conditions, especially when you're close to a bridge and you're aiming for a certain gap.
What are your thoughts about it possibly being a Chinese cyber attack?
@@TomdeSablathat was already brought up in the video, complex interactions between channels and changing tides could have affected it.
@@Mesuxyxrxbskxkxyp i would think they would want control so not cut the power, and in life shit happens. in tv shows like seconds from disaster its a string of litte things at the wrong time that lead up to it. its like a game of chance sometimes you get a couple of bad rolls of the diceon afther the other.
As a Traffic officer who's had to put on many a emergency rolling roadblock. I don't think many appreciate just how much of a miracle it is that officers can get the road fully stopped so quickly saving many many lives. Getting a RRB on this quickly is unheard of. Normally it takes a good few mins even if units are in the right position at the time. While i fully appreciate we lost a number of road workers which is a tragedy, things could of been so so much worse without this miracle taking place.
Thoughts are with everyone effected by this whole event.
Yeah that’s pretty wild. One of the first things I thought about.
I mean, after I learned that they were able to stop traffic, of course.
I heard it’s a toll bridge. Do you think the chain of communication would have included telling the toll operators to close traffic as well as sending units?
Some further questions for the general public:
Do they even have humans in tollbooths there? Were the last couple cars/trucks that crossed, running through automated lanes without paying because they thought it was malfunctioning?
Luckily it seems they did their best to lock it down in time.
I live in MD and work in Baltimore County Law enforcement. FROM WHAT I HAVE HEARD, MDTA was already on scene conducting a road lane blocking detail for protection of the construction workers. There was a patrol car at each end of the bridge. When they got word that the ship was calling a mayday, whoever monitors and controls ship traffic near the bridge heard that and then relayed to the MDTA dispatch center that the bridge needed to be blocked off, hence the rather quick response from the officers. Had that detail not been going on, who KNOWS how long it would have taken the Mayday to reach from the ship, to whoever monitors the emergency maritime channel office at the weigh stations for the bridge, then to the MDTA barrack that is right next door. And that's even gambling on if any MDTA officers were even in the office at 1:20 in the morning.
They don't have anything else to do other than write speeding tickets, so they had plenty of time😛
I think there were traffic control assets on scene for the construction work.
@@ObamaTookMyCat Right time, right place. Miracle indeed.
Sal. Retired Chief Engineer here. 30+ yrs as Chief Engineer on Slow Speed diesels such as this vessel. You have done a great job, but a couple of points to clarify.
1 - The ship's electrical systems are laid out such that there is a "Main Distribution Buss" and an "Emergency Buss". These two are NORMALLY 'TIED' together via the 'Buss Tie Breaker' and fed from the ships' main generators (DALI has Four). They can all be brought online to supply power. Usually one will carry the load unless there is a lot of refrigerated containers on board. When the bow thruster is running, two or three generators would be online to supply the Bow thruster which is typically an electric motor 1,000~2,500 HP. The Emergency buss is ALWAYS powered. In the event of loss of power, the Emergency Diesel Generator (EDG) starts, and the breaker connecting the two electrical busses (Buss-Tie Breaker) opens, then the breaker connecting the EDG to the electrical buss is allowed to close and power the emergency buss. There are only a handful of equipment that are on the Emergency Buss, ONE of the steering gear motors would be on this. The Deck lights are not on the emergency buss. So when you see the deck lights come on and off, that is a Main Generator. The large light on the bow that seems to come on at a different time is likely a High Pressure Sodium light and they usually take a while to 'warm up' before putting out any light.
2 - The black smoke is likely from the Main Engine (M/E). The M/E is a 9-cylinder two-cycle diesel engine that develops 55,630HP @ 82.3 RPM. The pistons are 0.90 meters in diameter and typically weigh around 7-tons each. If they were doing 8knots ahead and requested a 'crash astern' engine command, the automation of the engine has a separate program that will introduce more 'start air' than normal, for a longer time. 'Start Air' is high pressure air that is introduced into the engine in the same sequence as firing order to turn the engine (kinda like a push start) in the proper direction before fuel is introduced. Once fuel starts pouring into the engine in the reverse direction, the engine is initially starved for combustion air as the three turbochargers on the engine (that weigh as much as a Volkswagen Golf) take a bit of time to spool up to speed.
3 - I was an Engineering Officer, not a Deck Officer (Mates), but the mates used to remark about how the astern bells would affect the stern by 'walking' the stern one way or the other depending on how the blades on the 65-ton propeller bit into the water. Much more than the ahead bells because the propellers are optimized for pushing the vessel in teh ahead direction.
Hope this helps clarify some of your questions.
4 - The rudder is controlled hydraulically and without power, would stay in the last position before loosing power.
Thanks Chief! Great additional info, I appreciate it.
@wgowshipping Regarding the anchors, on the large container vessels I have smilede on as a mate, the anchor breaks are hydraulic operated, and the the pump needed is not automatik turned on egen the emgergency generator kicks in. An engineer needs to go to the emergency switchboard to turn it on. There is an emergency pump, which needs to be fetched, hydraulic hoses needs to be connected from the anchor winch to this small emergency pump, which can then be uset by hand craft. I have not seen these manually breaks for years as you showet on the footage.
@@wgowshipping ond more thing. It-baseret bit of a wonder that there hasn’t ben an accident befordr considering the large container vessels calling Baltimore with hardly any under kedel clearince and not much Air-draft.
@@douglastastad7437I would be normal to have both steering motor pumps running during departure/arrival, and at least two generators.
Depends on the precise design. If the engine was not fully up to temperature (as on departure) it would not usually be practice to rely on HFO for manoeuvring. The generators would be running on gas oil. The boiler would run on HFO.

But are you a forklift certified ham operator?
😂😂@@ApolloTheDerg
@@ApolloTheDerg Sadly no. I had to miss that class because I could not find my snow shoes.
Was this meant as a compliment or insult?
@@michaelkabler9276 You are kidding me right? You really have no idea?
I retired at the end of 2022 after working for 50 years at most every Port of Baltimore facility. Back in the mid 70's when the Key Bridge was built no one imagined a container ship of this size. When I started, ships with cars were still bulk carriers using the ships cranes to lift the cars from the holds to land them pierside! Now they are all RoRo vessels. I don't think the architects of the bridge could imagine the size of these behemoths now.
I watched Jeff Ostroff's video on this - one of his questions was 'why wasn't the span longer (making a wider space for ships to pass)?'. Umm, because the bridge is nearly 50 years old and ships of this size simply weren't on the radar when it was designed?
Just for giggles I did some Google searching. At the time the construction on the Key Bridge commenced (1972), the largest container ship carried under 3,000 containers. The Dali carries just under 10,000 containers.
In 1972, the only ships of the Dali's length were aircraft carriers, and a few transatlantic ocean liners, and in terms of tonnage, some of the largest tankers.
@@moosecati knew the Dali was a big ship i assumed around 6,7000 TEU under 10,000 is still just a medium sized boat.
You must recall when a container ship of this magnitude did the same thing yet why was there so much damage THIS time? Can someone check into this?
I am not sure if the size of MV Dali is that significant.
Simply because bridges are not designed to withstand such forces.
Also it is worth noting that both the Tasman Bridge and the Sunshine Skyway Bridge were brought down by much smaller vessels.
In the case of the Tasman Bridge on 5th January 1975. The ship involved was the MV Lake Illawarra, which was 7,274grt. In the case of the Sunshine Skyway Bridge on 9th May 1980. The ship MV Summit Venture involved was 19,735grt. An earlier event in the UK occurred on 25th October 1960 when the coastal tank barge MV Arkendale H and her tow the dumb barge Wastdale H. Which were of only 229grt and 233grt respectively. But the collision brought down two spans of the Severn Railway Bridge near Sharpness Docks.
In all three cases, there was a loss of life.
Boy, 30 minutes with you is well spent, Sal! I feel like I've gone to seamanship school! Thank you for these videos.
Glad you enjoyed it!
I didn't even realize that was 30 minutes lol
And not a minute wasted.
I've been sharing all his videos...on this accident.he is the best
@@Jenfirst-qt1sp even beyond that! the economic implications of shipping are huge.!
I have very little knowledge of the maritime world. But, I’m a Maryland resident and I have really come to value channels such as this as we try to come to grips with this tragedy.
Thank you, Sal, for providing so much sensible and insightful analysis.
Former Ocean Master here. This was a terrible accident, but Sal is doing great work with comprehensive commentary. Thanks Sal.
So great that you're spreading the word about other worthwhile UA-camrs, Sal! 😎✌️
You bet
Yes recommending channels I have been watching for years.
@@gregculverwellBut not newbies
@@gregculverwellNice of you to pat yourself on the back and tell us.
Well, Sal’s YT channel has been promoted also in Chief Makoi’s channel… it’s the reason why I am here. And found this to be good also. Chief Makoi is very detailed on things down the engine…it’s his specialty 😅.
Great report again. Having ran large tugs before I can tell you that it is not as easy of a job as it looks. I've never ran a tug in Baltimore, but I would never want to be attached to a ship this size going 8.5 knots. The tug I was running one day was a 7,000 BHP rated with 3 directional props. I was helping dock a container ship that is about this same size one day in a very high wind. It was about all we could do to hold the ship off of the dock and the bumpers that were in the water at the dock. The wind was straight on to the side of the ship with its containers all stacked to the top, so a lot of area for the wind to catch. The wind speed increased all of the sudden with the ship about 40 meters off of the dock, and boy could we feel it as the ship started to pull harder. I increased to full power on all 3 props with a fear that the tow line would snap and kill someone, so I got everyone off of the deck. We stood low in the wheelhouse. With all of this, the ship closed into the dock, but thankfully the bumpers in the water took most of the pressure and the dock or the cranes were not damaged. The bumpers however were toast and needed to be replaced when the ship departed.
With this ship moving at 8.5 knots, the only thing a tug could have done it it was there would have been to push on the starboard bow of the Dali to perhaps hold it off of the bridge piling. Lets be real however, under full power forward, these powerful tug don't go very fast and it would have been hard to get it up to speed an into place with enough lateral power to move the bow over. The propellers on a tug boat are engineered to provide force, not speed.
At the end of the day from what I see, they lost power at the worst possible time. when it happened odds are the engine room crew didn't know exactly where the Dali was in relation to the bridge and the approaching danger, but I assure you the phone rang down there and they were told. It looks like they lost power somehow, either the generator shut down for some reason or it was an overload trip. Often on ships like this if they have a lot of refrigerated containers plugged in, they will have 2 generators running in parallel to supply enough power. These refrigerated containers always require a lot of electricity when first leaving the dock since while on the dock they were often left unplugged for a while; so they're all working to stabilize the temperature in them. If that parallel generator tripped out for some reason, then the other generator would have also tripped off from overload. On these big ships, vital things on the main engine are ran with electric motors, not driven by the main engine itself like a highway truck. So losing power would also drop out the lube oil pump, and water pumps which then would have triggered a main engine shut down so the oil pressure accumulator can provide oil to the engine while it is slowing down. As your video points out, re-starting this main engine is not like hoping into your Ford F-150 and turning the key.
From watching the dock camera in real time it looks to me that the engine room crew was all over this in as quick of a manner as they could. Once power came back up from the emergency generator or a main generator, they started the main engine start process, and it looks like something then tripped it out again. But once they got the main generator started and isolated to provide power to the ship only, they got the main engine started and the black smoke you see was the bridge pouring on the power in reverse to try and stop the ship. At this speed and slower, especially in the reverse direction, the rudder does not respond that well since less water is moving over it than out on the open ocean at 18 knots. All this time, the ship was moving. It did slow quite a bit, but not enough.... Kablamo! Very sad deal.
I give aplomb for the bridge getting that MayDay call off so they could close the bridge to traffic. Even at 1:30 AM, that bridge is well traveled. While some were unfortunate, that MayDay call probable saved a lot of lives.
Yep, 😎👌.
Interesting post. It's good to hear from the professionals. I have zero trust in govt agencies so hearing from professionals helps when trying to understand something like this.
Someone had to imagined and thought in advance about the fact that one day any day or any night a vessel could have collided with one of those pillars, no one ever thought about that, no one had the brain and the balls to be in charge of ensuring safe and supervised navigation under that bridge, big vessels going in and out under bridges should have tugboats guiding them before and after they pass under any bridge.
@@AngelGonzalez-pd4cnif you had paid attention you would know there is little tugs could have done with a ship going that fast other than get their crews killed.
Thank You for that analysis. I just watched a British Gentleman's Video, states he's a ships engineer, and he also feels that the smoke indicates them pouring on the power in reverse. He also points to prop walk as a possible factor, as in reverse it would tend to push the stern to port, thus steering the bow to starboard.
I really really appreciate how you cite your sources in the video, and how generous you are in pointing and linking to related videos. Not everyone does this, but it's so important!
I appreciate that!
You're a class act for using your growing channel to boost other great channels. A rising tide...all boats...etc.
Sal, you do realize that you are for many of us our source of factual news on this event, yes? We have come to understand that typical media outlets seem to sensationalize what is actually going on. Thank you for a rigorous explanation of the events and your questions and concerns as opposed to stating them as facts. Keep these coming, thank you so much for what you do here!
Thank you so much.
The legacy media, along with all the other federal agencies, have lost all credibility.
They’re as honest -and as credible- as an obviously drunk alcoholic who is telling you that they haven’t had anything to drink.
Indeed. I have so little trust in MSM now that I only use them (because they're typically first getting a story out) to get the what, the when, and the where.
Subsequent to that I turn to indepenent sources (like Sal, Mentour Pilot etc. for transpotation) to get to the political bias, narrative free, FACTUAL truth on the who, the why and the how.
Great video and information. Keep up the good work and thank you for the other sources.
Agreed. We are also watching his channel from Africa. My hubby is American. And we stay connected.
Living in these days, there is a tendousy to look for terrorism everywhere... nobody wants to expect the worst from other people. It's still a broken and fallen world. Do you thnk their might be some sort of sabbotage going on, on this skip?
Should the crew at least knew about water Flow coming in from the left on the screen and act accordingly with speed, ect? It's a big Flow of water with that weight even coming from that size of vessel?
I think a key takeaway from this accident is to start the emergency generator when crossing under infrastructure or near tricky routes. The generators have to be started periodically anyway so it's a low-cost in terms of effort. also to come out of this it may be useful for the harbormaster to become a quasi air traffic controller in harbors with vulnerable Bridges to make sureBridges can be shut down immediately, low-hanging fruit would be to put traffic lights at the end of bridges that can be acted on immediatelyimpossibly some flashing yellow hazard lights in case people are working on the bridge to know to evacuate. Of course vulnerable Bridges still need dauphins, but until those changes can be implemented these are great ideas to shore up the weaknesses.
My father is a Retired Chesapeake Bay Pilot, and he is heartbroken.
Would you please thank him for his service? Harbor pilots don't get the credit they deserve.
Boy your father made good money. Do pilots get a pension???
Ahhh! I know you! Our fathers used to have PSL tickets together! Hope you and your family are well! I think of y’all often! ❤
Not trying to be a wise guy but I'm a Marine electrotehnical officer (ETO):
Emergency generator usually supplies key machinery and equipment.
If the steering gear is composed of 2 pumps, driven by two electrical motors, one of this will certainly be supplied by the E/G.
At the moment the emergency lights turned on, they certainty had power to the Steering gear emergency pump.
From this point I can only guess what happened, but from the electrical point of view, I believe they had control of the steering gear for a brief moment before the second black out.
I know after a incident everybody find the best solutions, and ideas.. I just hope this info is helpful to anyone interested.
Cheers!
Your right... The ship should not have been aloud to leave the dock. For 2 days they had endless electricity problems, over loads failed systems.
hello ETO, you are absolutely right about the emergency energy supply.
i have been a marine engineer for 40 years and found, that the shipping companies are trying to reduce costs of having at least 2 tugs, by using bow and/or stern thrusters.
however, these do not operate on the emergency power supply, so the vessel is doomed with a black out.
there should be a requirement from the insurers, like Lloyds of London, ABS and others to make sure, that a vessel is accompanied by sufficient tugs to reach the open sea.
during my last years at sea, before retirement, i also found that shipping companies were introducing cheap and cheerful staff to man their vessels.
whilst the well educated officers in the Netherlands have been sacked by the likes of the Danich firm Maersk!!!!!
it all comes down to MONEY!
Finally someone on youtube who speaks perfectly: not too fast, appropriate emphasis, and a voice that can convey complex info
while not sounding like the keynote speaker at a CPA Convention. Gen Z take note: you do not need to speak at 125 words per minute to convey a narrative on UA-cam. (And you can do it while _NOT_ sounding like a god damn stimulant junkie) This guy has broken down very complicated marine engineering processes in less than 32 minutes, and in a very understandable way. Significant to me because all I know about boats - is that the nicer they are, the more women they come with. Thank you "What Is Going On With Shipping" - great video!
Give Gen Z a moment to grow up
This channel is an absolute gem. Thanks Sal.
200 mil. lbs.? is that correct?
I didn't realize i've been watching Sal since day 1 of his video's, it was funny the day i did.. Love this channel
Me too. Super neat to see him grow
Channel. I see what you did there.
I'm sure the collision went just as planned.

As a Filipino American, I am happy to see Chief Makoi educate us about operating ships in the engineering room. Great job to you and everyone involved in this video. I’ve been following your channel ever since the Oceangate disaster.
O dear me. KAILANGAN pang BANGGITIN ang (dual) NATIONLITY. Oh yes dahil makakatulong sa info na malaman ng mga readers kung anong nationality. TYPICAL Pinoy. :)
Indeed, Chief Makoi is an excellent teacher. I enjoyed his video on bauxite liquefaction.
Sal is one the most IMPORTANT UA-camrs of our time!! He is also an absolute BEAST at what he does!! 👍
I saw you on the news and told my son - hey! that's Sal! Well deserved. I can not tell you how much you give us all with your knowledge and how much better off we are for it. Thank you.
He also was on Bloomberg "Odd Lots" podcast, where he is a favorite I think! It's on Spotify, Apple, Google Podcasts and elsewhere. Good episode!
Yes, I appreciate that he passes on information of other channels to educate ourselves!! Much appreciated!! 👃👃👃✌️🥰🇨🇦
Thanks for the update and info.
It is sad that I discovered your channel only after a disaster, but you do have a lovely channel. Thank you for the great content and breaking it down into a form a layperson like me can understand
Same here. Hate to admit it, but this whole thing earned him my subscription.
Keep watching. I discovered Sal's channel completely by accident a few months back - I didn't have a clue about shipping and its geopolitical connotations before, but now I learn something new with each upload. Just don't do the Bab-el-Mandeb drinking game, it'll get expensive and result in occasional hangovers ;)
This channel started because of a marine incident, the Ever Given blocking the Suez Canal in 2021.

I know no pun was intended but…”there is a lot of information floating out there” gave we a smile and chuckle.
Lol
My now 84 year old Dad retired from USN in 2005 and called me earlier today asking if I knew of anyplace on the internet to get quality news about the bridge thing; "Well, Dad, as it happens, there is this guy named Sal Mercogliano ..." Dad was considered an expert ship handler back in the day, it appears to not be an inheritable skill, my own skill level extended only to canoes. 😄
Have fun with your canoe 😊 just don't get too close to gators
@@nidheeshkumar6760 Hehe! The Grumman aluminum canoe was purchased by Dad and Mom when we lived on Naval Weapons Station at Charleston, SC where at the park there was an alligator people had named Margaret and she came when called. She loved to swim along scooping up the giant marshmallows you tossed in the water after buying them at the little PX. Did have a lot of fun with that canoe. My health is a mess now and those days are over, but the memories are grand.
Canoeing is good. 🛶
Your channel is superb. Clear, rational, easy to grasp if you have a basic head on your shoulders.
Hi Sal, I was a Captain on different types of ships. I have also gone as one of the Captains on board newly built ships at the Cochin Shipyard. These ships are taken out to sea for almost 10days on sea trials and we do something called a crash stop trial where the engines are put from full ahead to stop and then full astern. It is during this trial the stopping distance is ascertained. When this type of manoeuvre is done a lot of smoke emanates from the funnel. With a right hand pitch propeller the bow will cant to Starboard (right). Could that have happened here? Kudos to what you do.
Chief Makoi put a thing on his "community" page that he will be putting out a video about the Dali and the incident in general.
Oh, thanks for the heads-up, I’m much looking forward to Chief Makoi’s perspective. 👍
He knows a lot about large ship engines, definitely worth watching.
I’m not a seafaring person but I just came across this channel the day of the crash and this is what I wish the news was like on tv. I can’t stand to watch that crap but this type of video format, I like.
absolutely agree, the news will keep replaying a 5 minute segment over and over and it hardly has more info then "ship hit bridge, bridge fell".
but a channel like this will give so much information and say where info isn't available and where guesses are being made and so on.
Well, stop watching that crap, then. I cut cable in 2011 and started streaming. It changed my life and I've gotten a lot smarter.@@ARockRaider
Independent news media is the news now. MSM will be gone soon.
Big hats off for promoting your fellow professional friends in this trade/industry. 👍👍👍
Thank you for this video. The incident has caused a huge amount of BS on social media from folks that are clueless. Now, thanks to you I can share this informative video with others. Thank you again.
I wish we had reliable and informed reports like your on all news topics. What a different world it would be.
A wish is the smallest form of accomplishment by a person. It is the wanting of something without paying the cost of achieving it.
yah that would be nice, but the powers that be prefer a panicky and uninformed population so the major news outlets make sure to only provide enough info to get people worked up.
@@senatorjosephmccarthy2720 what could any single person like OP do besides luck across good informative channels on every relevant topic? and be doubly lucky to not stumble into an uninformed channel spreading panic and hearsay?
Alas, those wearing aluminium foil headwear won’t be swayed by facts or common sense.
People like you are why I only watch UA-cam these days! Thanks for an other amazing video and sharing what you know with us
Same here. There's just no real way to get in depth information on many topics through other media.
I really appreciate content like this and the YT partnerships or colab. with others like Ward and Chief Makoi. Your presentation and information is top notch... something you will never find on TV.
Thank You. ♥
I’ve watched tugs wrangle loose barges on the Mississippi River, so impressive. Those beautiful people have chased down 20+ loaded barges that were headed at the Hwy 190 bridge in Baton Rouge, none hit. There is a very tricky curve just north of the bridge.
Sal the community is very lucky to have you. With how you break everything down into easy to understand pieces. Phenomenal job thank you for sharing your many years of experience.
I appreciate that!

I have been subbed to Chief Makoi for years! Great channel!
Cool dude nice kindley chap no crap.
Me too, unfortunately lately not so frequent.
Between friends, Chief Makoi is one busy dude... sometimes other things get in the way.
Thanks Sal. You are my go to for all things shipping.
4 of our company tugs stuck in Baltimore. Products affected are Jet fuel, concrete, and sugar. Lots of other products affected I'm sure.
Expect north half of the channel open soon. Very large cranes, and people who know how to get things done.
I am very happy I found your channel. I'm a former civil engineer / program manager at the Army Corps of Engineers. The effort the Corps of Engineers is beginning will be historic in scope. I look forward to following the story with you.
Came here as per Ryan Macbeths suggestion and I can confidently say this is one of the best informational UA-cam channels I have found recently. Awesome content and awesome video. Thank you for the quick coverage.
Your explanation of this event is awesome. For people not inside the shipping industry the media has done a terrible job explaining this.
And conspiracy theories running amuck, thanks to MkUltra, big Media etc
I'm shouting ACCIDENT from my brief decade of mariner experience... but nobody listens. I just get in telegram jail... thanks Sal and knowledgeable commentaries here
@@ladavidson9269 brief decade of mariner experience.you had posted you were a 50toncsg captain on another video.
Whenever something like this happens, I always know right where to go. Thanks for all you do Sal!
This channel is an example of UA-cam at it's best!! Thanks Sal
it's down to Sal , not ytube ! :)
So true --thank you Sal.
Great job Sal! RIP to the bridge workers.
It is good to get intelligent and informed explanation instead of the wild speculation that the News Media and more than a few bloggers are providing!
One blogger I respect has a rule not to make declaritive pronouncements for three days because the first reports are usually wrong!
I appreciate your telling us what you know and what we need to find out!
I also appreciate your giving us reliable and knowledgeable sites to go to for more detailed information!
Found your channel back when the shipping supply chain was a cluster and I wanted to know more about what was causing it. Was so impressed with all the detailed information you provided that you've been my go-to for all things maritime/shipping ever since. You always deliver and this time is no exception. Thanks for keeping us informed.
Your channel is an authoritative source more than any other I know of, including some big names. As precious as ever in these crazy times, when competence and knowledge are even derided.
Well done,as always, Sal. The woman who speaks for NTSB is good. With AlaskaAir door plug, she would not let news media pressure her into jumping to conclusions. This is going to be a complicated investigation and will certainly take time.
Great to see this channel getting the exposure is has deserved for a long time now💯👊🏻⚓️
I subscribed to this channel last summer/fall because I thought it might be interesting. Holy smokes, has it ever been valuable since then with all the stuff happening in the Red Sea, Panama Canal, containers, insurance and now this. I have always thanked Sal for his informative videos. Today, I add to that for all the reference sources for additional content so we can all better understand the environment and constraints that everyone was operating under. Thank you, Sal, once again!
Thanks George!
I started watching you because my son is in the Navy in the thick of it in the Red sea. Thank you for all you cover and all you educate
Long way to go on this investigation. Hopefully people will read the final NTSB report when it is issued. Amazed that MDTA was able to close the bridge so quickly but it just so happened there was construction that night. RIP construction crew.
PS - Thanks for making and posting the video.
I have shared your videos on this incident multiple times because I think everyone needs to be properly informed of what's going on and what's to come without all the sensationalized reactions that news media can push. Thank you so much for being such a calm and rational voice during this horrifying situation.
I am concerned about the 2 or 3 crew who were stationed on the bow of the ship manning the anchor. Where were they when the bridge started to collapse on the bow of the ship? How did they escape injury?
We have such a long road ahead of us. Prayers for the families that are waiting to get their family member still missing back. A go Fund Me was created by Baltimore for the family members to help with funeral arrangements and expenses.
That should be covered by the ship’s insurance!
@@supergeek0177 It probably will be covered, along with other payments, but for now the families have to deal with this tragedy however they can.
@@supergeek0177 no funeral home or cemetery is going to take a letter that says, "The ship's insurance should cover this!" Eventually, reimbursement may happen, but these families have needs NOW. I doubt their independent contractor's insurance is done saying why They won't be covering this. I'm guessing the county and state and port and DOT are all *sure* it's not their responsibility either. The families can't wait on entities and lawyers fighting with insurance co.'s from different countries all dickering over who owes what. Everything costs. Death is a "pay up front" expense. These workers deserve dignity and respect at the Very least.
I started watching this and became mesmerized, and educated. Wow, just wow.
His channel alone has taught me how involved the maritime industry is. There are so many layers to everything involved it's fascinating
@@Mr.Thermistor7228 Yes it is! At 66 you’re never too old to stop learning. I teach music at a Middle School and tell me kids to learn something new EVERY DAY!
You, sir - have earned my sub. The quality and information on this tragic incident gives me the facts and details that we don't see in mainstream media. May the families and deceased receive the peace they need in this difficult time. 😕
This video was done in a way that I didn't get lost (I can paddle and know the basic function of a keel) and feel like I understand this a bit more. The other comments on this video filled in some gaps as well.
My head just cannot wrap around how massive this ship actually is as I'm in the Midwest. I've seen Shipping ships from descending in flights, but it doesn't put size into perspective.
From what happened to the ship and quick response from the pd, my questions were answered by this video and the one from CN you recommended (I came from that video). Thank you for teaching a Midwesterner a bit about ships!
I hope the clean up efforts, reports, and subsequent rebuild go properly keeping in mind everything that we have learned to prevent this from reoccurring in the future.
Thank you for doing such respectful references to the other maritime channels. You are a good human
Finally someone who knows what they are talking about. Thanks for these great videos
You are right Mr. Sal, the tide coming of Curtis Bay would definitely kick the stern of the Dali over towards the Dundalk side, just the way we see the Dali moving in the crash video.
People who have never lived by the sea have this weird idea that it is safest around low tide when really the exact opposite is usually…… i am reminding of the scene in the 13th warrior “land? This is not time to be close to land, little brother”
@@MrSheckstr Just don't run aground at high tide.... shorter wait to be lifted off by a rising tide :) . Just stay in the channel if you can. The Dali couldn't :(
I've done a lot of marine salvage work and do not see any significant technical problems. Also, as a former British merchant navy chief engineer, I can assure you that it is very easy to start a marine diesel engine. The engine room crew should have been ready on stand-by and the engine all set up to stop and start on the passage out of Baltimore.
Attaching a tug to a ship doing 8-9 knots can be very dangerous for the tug. Girting is a real possibility.
Engine and machinery data is also recorded on the engine control room printer.
The black smoke is caused by turbocharger lag after starting the main engine. It takes time, and until the turbocharger gets up to speed there is insufficient air for combustion, hence the black smoke. Most probably the engine was started astern. There is no issue with the propeller spinning.
All essential systems can be switched to manual overide.
Thanks for the shout out to Chief Makoi and Brian Boyle. Both offer great resources for understanding the work of merchant mariners we all depend on.
Now this is the information that everyone should listen instead of jumping to conclusions as you see on the comments on any news video. Thank you for detailing the incident and also shouting out to other UA-camrs on the how to tutorial on the cargo ships or other large ships.
In a way, it is sort of amazing that about 2 and a half minutes from the mayday and they were already cleared the traffic and only the workers were still on the bridge.
Where did you hear that?
After watching this video and reading the comments I have come to the conclusion that YES, something very bad went wrong at the worst possible time onboard the ship BUT the disaster happened SIMPLY BECAUSE THE AUTHORITIES FAILED TO UPDATE THE DESIGN OF THE PIERS THAT WERE SUPPOSED TO PROTECT THE BRIDGE PYLONS IN THE EVENT OF A FORESEEABLE SITUATION LIKE THIS.
If the piers had been re-designed and reinforced back when ships of this size became "the norm" in these waters, then this ship would have run aground on them and possibly even sunk.
BUT THE BRIDGE WOULD HAVE IN ALL LIKELIHOOD SURVIVED.
Now we can look forward to all the responsible authorities start to blame budget cuts or labor shortages or the fact that their own underpants did not have sufficient balls in them TO DO THEIR JOB PROPERLY.
Updating the design of the piers would require rebuilding a bridge, as adding sufficient sized artificial islands can't be retrofitted, they would take up too much space and be a hazard to shipping (replace taking out a bridge every 4 decades with taking out a ship several times a year). Yes, they could fix this by a new bridge or replacing it with a tunnel, but there are hundreds of bridges in the US like this, and none, not even the ones with the relatively small islands shown in this video, could actually have stopped a ship this size. There's probably 5 bridges in the world with enough protection. Ultimately, with 6 fatalities, and one bridge out, it's likely still not going to pass a cost / benefit analysis to replace all the required bridges.
Here they simply don't let large ships transit at all and just moved the entire ports to reclaimed land downstream. Rebuilding the bridges is simply not cost effective.
@@peter65zzfdfh Dolphins could be added leading to the bridge piers, not encroaching on the channel. It might be possible to add fenders through the opening, by sacrificing a small percentage of the channel width. Now that the bridge is gone, there is the opportunity to build to modern standards.
Great video, very informative. Worked offshore in the north sea for forty-five years, before retiring. Been on a platform when the supply vessel hit the leg. Scary stuff, sitting in the lifeboat crapping ourselves waiting to launch. Luckily we didn't have to abandon.
Wow! An actual fact based anaysis about the incident. Too bad people have given up on waiting to have facts before blurting out opinions on social platforms.
Thanks for a great video!
Sal had a short video up right after the collapse, and it was pretty close to current theories.
I have gotten so much from this channel, but even more I love the fact that in free countries all information is available to everyone. I hope you get it fixed soon and for as little casulties possible
in free countries all information is available to everyone . . .
Love your channel. So informative for all of us who what to understand what could have been done to prevent this horrible incident. Thank you
Thanks Sal!
I hope like hell that folks will watch and LISTEN to what you are doing here.
Thanks for the links as well.
More education is ALWAYS a good thing.
Great work sir!
Thanks again.
😎👍
Thank you for being a rational voice in the noise. educated speculation, when made clear that it is speculation, can be very helpful to those of us looking to understand. It is sad how quickly this event turned to cynical hysteria and fear mongering.
Yeah, it really is sad. As such, clearer and more educated minds were drowned out. People want instant answers and to wrongly point the finger at things that either had minimal or absolutely no impact on the situation.
And the worst part is that the majority of people will forget about this incident and continue to spout disproven lies and falsehoods.
"A lie travels halfway around the world, before the truth can get its pants on."
I can't imagine why people wouldn't believe the official account from the same people who claim women can have a d*ck & men can have babies.

Key takeaway here is that the ship’s systems were not uplinked.
Meaning, this was most likely NOT a cyberattack as several high-profile media types have insisted that it was.
Most likely NOT a cyberattack because the press stated around 8 am it wasn't.
care to explain why that announcement was made?
@@mkuehn5450 I cannot explain why that statement was made.
I wasn’t in the loop.
@@user-jn9pk5dd2z your statement "meaning this most likely NOT..." was equally 'in the loop'
thank you
@@mkuehn5450 Hold the snark.
I was expressing my opinion when I said “…most likely not a cyberattack…”.
Those who insisted that it WAS a cyberattack were expressing their opinions.
@@user-jn9pk5dd2z any 'snark' was aimed at your misinformation about "uplinked"

Hey Sal. I saw you over on Ward Carroll's Channel. I've been telling friends that watch the same channels as I do to go look at your channel if they want to get the best coverage for what's happening at the Key Bridge.
Keep up the good work.
So basically, once the electrical system tripped-out, there was nothing anyone could have done to prevent this, and the bridge was completely unprotected. It was just a matter of time before something like this happened.
It really was and it still is for every bridge seemingly completely unprotected. It almost certainly will happen again if nothing changes
This is why money for upgrading old infrastructure in the US needs to be approved by congress. Bridges, roads, ports, electric grids. There are vulnerabilities that need updates.
@@Mr.Thermistor7228 Seems to be a worldwide problem, not just a US one because "thrifty" is worldwide.
This is the part that bothers me. I drove over the Key Bridge daily for nine years. I had no clue how vulnerable the bridge was.
@@juju1896Ah, and therein lies a major issue with big goverment and career politicians - that kind of spending doesn't generate votes. Issues that do generate votes that do 'require' spending are things like Ukraine, women's issues in Pakistan, taking total care of illegal immigrants and any other issues screeching leftists fill their vacuous lives with.
Nothing will happen with those "vulnetabilities" until something bad happens and only IF the public outcry is large enough.
Greetings from Asunción Paraguay. Great analysis as always.
Love the way that non-suspect experts are reviewing every bit of info. We've come a long way since we forgot to remember the Maine!
Glad to find a source of more detailed info and discussion. With so much BS about conspiracies and intentional acts going around, I'd like to see people with this level of knowledge on the news and getting publicity. I've learned more from your videos and the comments on them than I have from any major news source.
Thank you for a professional and reasoned review of the incident. Very educational. It's a huge breath of fresh air compared to the media's hyperbolic nonsense.
Really good information. Glad you are spending the time to explain all the items to us lay people. It's amazing how many complex things are in this world that we know nothing about until something like this happens.
Don't know anything about maneuvering ships of any size. But when I saw that the start of the issue to impacting the support on the bridge was about 4 minutes..well that is not just not a lot of time. I think they did the best they could in the time they had.
When the first power outage occurred the first call would have been to the port captain to clear the bridge and shut it down. Had the workers not been on the bridge, there would not have been the patrol cars with officers there. They would have had to be sent to the bridge and I highly doubt would have made it in under 4 minutes.
People always over things.
Should have not could have…
Fantastic work Sal, been sharing your work to everyone to combat the rampant disinformation.
the last minute swing to the 'left' is the bow running into the edge of the dredge
The requirement for bridge voice recorders by IMO is absolutely fine. Problem is that no one seems bothered when they are not working properly at the mandatory annual inspection and survey. When working properly, you can compare microphone input time differences and determine not only who said what, but where they were when they said it. Don't read too much into the "issuing rudder orders"; if the ship is blacked out then all the helmsman is doing is moving a switch on the bridge that isn't "commanding" anything (applies to FU, NFU and Autopilot modes). The lack of the VDR recording data for periods before the allision could well be a lack of data being supplied from the INPUTS to the VDR being offline.
No one seems bothered? Well, if you have VDR out of order for any reason, even with single non-active channel (like corrupt nav data - log, or echosounder, or anything like that), your VDR will not pass Annual Performance Test and then you have to seek an exemption from flag. They will grant it for 30 days, perhaps give you an extension, if you are in a bad part of the planet, where service is not available. Eventualy, all must work.
As to the steering - one steering gear pump must be supplied from emcy genset. After 45 sec of blackout you will have rudder, if all works correctly.
Jaun Brown sent me. Subscribed 20 seconds into the first video on this accident. Top notch info 👍 Now if only the regular media would report this well.
Did he do a video? I must've missed a notification! I mentioned him in my comment here. Sal is like the blancolirio for shipping. ✌️😎

so thanks for the facts.
When the correct information is needed, you are the source. thank you Sal.
Thank you for this enlightening update without trying to sensationalize things.
These videos are very educational and informative. Thank you, Sal.
Some notes about the Sunshine Skyway, which connects St Petersburg to Bradenton. That disaster was weather related. A blinding rainstorm led to that collision and as you saw, part of the bridge remained intact.
It took 7 years to build the new Skyway, but a much longer span was built to replace the center of the old bridge.
Thank you again for enlightening us on shipping.
Awesome ❤. Love that your shining a light on other youtubers with relevant info. Hope all the people with questions take advantage.
Mr. Sam,
18 hrs retired now as a chief mate, have experience from feeder to 10800 TEU vessel’s at my time & PCTC’s, Every scenario is different,often Master’s in not mandatory areas save money from not taking assistance from tugs just to claim as bonus from the ship management company’s for saving towage fees which is substantial, & according to the DWT of M.V DALI towage fees could be easily be over at least USD 6K each/single berth operations provided that she has multiple BT’s and by the history of the vessel, she has been detained for deficiencies specially in ER.
Hi Sal. I am here and have subscribed because of your interview with Ward. I learned so much. Thank you
Really appreciate the detailed explanation! I was concerned about sabotage or malicious behavior. While watching the specific details, I’m confident this was the Swiss cheese of risk analysis where each part of the tragedy lined up to create the tragedy!
The unknown factors are the only thing that will help us understand if this was intentional or just the perfect storm of bad luck at each interval that lined the ship up to strike the bridge exactly the way it occurred!
Once we know how this occurred at each step we take those risk factors and use them to prevent any future disasters!
My second thought is timeline expectations and cost, if you have anyone that can help us with this in a follow up video, I’d love to know big picture ideas on what’s next!
Thanks, for the education and now you have a new follower. 😎
