Not even watched yet, and already know the content will be concise, free of the usual MS media BS, and non biased commonsense coverage and delivery of information....cos Ward and Sal....the two guys responsible for two of the best channels on YT....thanks in advance to you both for this coverage, cheers from Sydney Aus!!!!!
Watching from Tokyo, dittos! Many thanks to Ward and Sal for sharing their expertise and commentary. Cheers.
but it is 20 min long, and people just can't sit still that long. they WANT the MSM BS, we live in the tiktok generation of 15 second attention spans. We are getting dumber as a species.
Of course! These are two men who have spent their lives doing things that if done incorrectly, people died. They are the epitome of competence.
True story, bro.
You were right 👍
Sal is the boss for maritime matters. Found his channel when Evergreen blocked that canal and have been subscribed ever since.
I have no professional knowledge interest in shipping, but as an everyday person I find his videos fascinating.
Sal is to maritme affairs ad Ward is to naval aviation.
Expertise AND the ability to deliver that expertise to the layperson person.
Rare combination.
One of the key elements of the operation thus far is that the professionals were allowed to do what needed to be done WITHOUT INTERFERENCE FROM POLITICIANS. The selection of the Corps of Engineers to coordinate the effort was key. The normal distractions of media interference was controlled and the public kept informed through knowledgeable sources. FEMA and Homeland Security need to use this as a model for future disasters. An event of this nature should never be viewed as a political opportunity.
Yep, and they beat my original estimate for moving Dali, by two weeks. We shall see if they get the channel fully cleaned up for large container ship transport, by the beginning of June.
Best wishes all.
To be clear and by no means to be critical of your comment. It is FEMA that has all the training materials and classes, etc. to run a unified command. It is called the National Incident Management System. I can assure you it is very rigorous and successful. I say that having completed the first two "modules" online and the next two resident courses of NIMS Gtaught by a county Emergency Management Division. Plus about a dozen other courses. All the online ones are free for anyone at all. They would be well worth anyone's time. Good fortune to you!
EVERYTHING is a political oppty.
@@andreweppink4498I'm shocked the idiot in the White House hasn't taken credit yet. He's lied about everything else in the last three years.
@@andreweppink4498especially your comment
Ward is absolutely correct. I knew nothing of maritime life and this video is a class act. Thank You!
this tragedy is a blessing in disguise on how we need to keep our merchant fleet and harbors safe from incidents such as this.
Reminds me of one of my favorite life sayings: “Life is maintenance”!
A very intelligent, and well spoken video. So many issues that a person like myself would never know to think about. So many different considerations. Lord please keep watching over all of the brave souls working on this disaster. The very mention of the Coronado bridge sent chills down my spine. I've sailed under it many times.
I went from Miramar Nas to Coronado Island all week we were tdy. got to see the ranger at the pier that was the best part of the week. crossing the bridge is spectacular because of the height and the curve too.
Someone mentioned the san diego/ CORONADO BRIDGE IN CAILIFORNIA .....I HAVE RUN THAT BRIDGE IN A FAST CAR AND FELT EVERY SWAY AND BUMP GOING OVER ... MY PARENTS WERE NAVY AND THAT WAS THEIR WAY TO WORK! 5 YEARS PASSING OVER THAT BRIDGE WITH A MANIAC CALIFORNIA DRAG RACER HOBBIEIST
I was an engine room or fresh air snipe when I served on board my Navy ship. My job during exiting and entering port was operating that anchor windlass (the anchor chain machine) during Sea & Anchor detail operations. I cant imagine being on the Forecastle with tons and tons of bridge debris raining down on our heads. Crazy scary! . Thanks for the excellent updates from both of you! And kudos to all the folks and agencies involved here, This "recovery" has proceeded amazingly!
Great work Ward, continuing to bring us the news that mainstream outlets skip over or ignore. Keep it up my Man!
Visas are not required to change out crews. With a maritime transportation service (basically a taxi with port access) they are taken to Customs where paperwork is completed, that allows the mariner to be escorted to the airport.
Thank you WARD ( SIR) 😊 my F-14 REO
Friend for having ( SAL) the best description of step by step on the Baltimore issues 😊❤ my heat going out to the 6 lives lost. And Baltimore as a shipper port. My Hat is off to the Coast Guard small buoy tender crews that were setting up the temp channel very soon after the accident. Those are the CG guys that never get the camera when all you see the CG on Television is Rescue training or real rescues at sea. Those CG buoy tender guys and gals are the ones to make channels safe for navigation. Boy they worked fast. And the sonar crews that marked the bottom section of the bridge. Fast outstanding work. 😊
Great insight! Thanks Ward for getting Sal on board!
I wish I'd had that saying, "Ship happens" when I was on my submarine. We had lots of pithy sayings about life onboard, but that would've been a cool one.
Two of the best channels on YT. Both are excellent sources of accurate and necessary information. Kudos to Mooch and Sal. This video was fantastic as expected 👏
Two of The Finest back for a chat. Nice to see you both, gentlemen. Thanks for doing what you do!
Sal is such a „round“ character, it’s always great to see him work with other content creators I’m subscribed to. Thanks from Vienna!
Brilliant comments by Sal - as an ex-Master and retd DPA, some of what you've said about crew fatigue, visa requirements and underlying mechanical causes to such an accident are always on my mind!
What a pleasure listening to & learning from two professionals!! Tell it like it is. Thank Ypu!!👍👋😇
Love the collaboration between you two. Always great info and content when you guys get together.
Great to see Dali at Seagirt. I enjoy ward and Sal who give so much info. I'm an old bold pilot with private pilot license in October 1968 at Allentown PA Queen City airport. I worked at Bethlehem Steel over 20 years, many at Sparrows Point.I lived in Annapolis on the water and also Cape ST Clair. I soloed at 6 hours on Runway 25 at Queen City Airport, an afternoon thunder storm hit just as I took off in a Piper Cherokee 180, exciting climbout and which wind was now a full crosswind from the south. I landed in a large crab and some slip. My flight instructor was Don Cameron who landed an Canada flight 797 which was on fire in 1983. half passengers survived, and Don was dragged out of cockpit. Don had 13,000 flight hours
Synergy stated late yesterday that after Baltimore actions are concluded DALI will go to Norfolk.
Merchant marines - the unsung heroes of world trade. What a tough life!
Thanks Mooch and Sal.
Sal always has an interesting perspective. Thank you for recommending his channel.
I was pessimistic of how long it would take to get the damages cleared and even having a shipping channel available. Well done to the salvagers; they have made dramatic and decisive differences in correcting the problems.
Two the best UA-cam personalities ever!
Always the best two experts on air and sea operations.
Thanks Ward for having Sal on again. I've been watching Sal since you first had him on. Great choice.
Super video! Always enjoy seeing Sal on the show!
Thanks both of you for the great information as always.
Two experts here. Blessings to you both. A somber Memorial Day [date of my commitment]. Please don't cease regular posts together!! Aloha and Mahalo gentlemen 😅
Good job, Mooch! Thanks to you and Sal for keeping us apprised of this ongoing drama!
I assume (and hope) that somebody is looking at the collapse of bridges as a potential strategic threat - for example blocking the Pacific Fleet in harbour.
Dude, your videos are awesome, keep it real
OK DUDE.
Thx 4 the update guys! Incredible teamwork by the players! BZ
Ward, I was at the Blue Angels Foundation event yesterday during the “rehearsal” show. Was hoping I’d see you and get a chance to shake your hand. I had a great time anyway.
As far as removing containers from Dali, I would think they will have to remove the road debris at the same time to keep the ship in a level state. There is a huge block of concrete bridge support there in addition to the roadway.
Container ships have the ballast capability to keep ship upright. Anti healing system is standard
Thank you for wrapping this up. The update was very inclusive.
Excellent discussion! Thank you Ward and Sal!
Look starlink is just a huge game changer for ship's crew to get communication to home
Thank you Ward and Sal
Thank you for the update 🇺🇸
As Sal said, there are many questions regarding why the ship lost power and hit the bridge. I am focused on the vector of the ship after it lost propulsion. Why did an adrift ship (no propulsion) pivot 15 degrees to starboard into the bridge? The current was less than 2 knots and negligible wind was reported. The port anchor was dropped but not set, so it did not affect the ship's pivot. Even then it would have drawn the ship to port, away from the bridge. The best I came up with is prop-walk from a right-handed screw and bank effect or in this case channel effect. The right-handed momentum continued after the screw stopped turning. Channel effect is water being sucked under the vessel, simply from the displacement of the ship, from the bank to the right. The incline of the bank causes a strong current under the ship which in this case would pivot the stern to port and the bow to starboard into the bridge-after the prop stopped. Channel effect would change the vector of a ship that size easily. One other factor would be the sudden loss of squat after the prop stopped turning. This would produce a quick buoyant lift upward and forward, contributing to a change in vector along with the other aforementioned dynamic forces on an adrift ship in a channel.
I don't know the mechanics of it, but boats and ships yaw when they lose propulsion. That's probably one of the least mysterious aspects of this incident.
@@stacymcmahon453 Yes, the prop rotation ( I assume is right-handed) stopped, created yaw, or movement on the vertical axis which helped change the ship's course. Along with the bank effect and the sudden loss of squat. As for the being least mysterious? I suppose it's not a mystery but, as far as an investigation goes it's important to establish the fact patterns. To know why the ship pivoted to starboard is vital, as there are physics involved out of control of the operators. In other words, the pilots did not turn the helm in that direction, there are physical attributes that did it. It's all this legal stuff that has to be determined to exonerate the pilots who did all they could possibly do. Its just fascinating to me and I suppose the fact that I work with two Retired Coast Guard ship accident investigators I have a personal interest in the details of this investigation. Can't wait for the full NSTB final report!
YAAAAAY!
Love it when both of you collaborate! Sal is wonderful!
Thank you Ward.
(And when you and Rick Beato collaborate, too!!)
🥰👍🏼
Thanks for a good report. Glad to know things are getting better. This was pretty dicey. Sounds like everyone's done a good job dealing with it. Pick up the pieces and move on. Take care.
Thank you, Ward and Sal! 🙂👏😀
Great job guys
Thanks Ward for all you do.
Any ideas being discussed concerning the new design for the bridge?
How might its construction impact port traffic?
if it ends up a cable stay bridge like what I've seen proposed, once the towers are built, only marine traffic impact would be certain timing issue as they moved road sections out on the cantilever, no water access required other than safety related...... I've been watching the Gordie Howe Bridge go up here in Detroit, I think it's 1 section away from joining the sides now
Top shelf gentleman and much appreciated!
Good Afternoon Ward. Hello from Eastern Texas. Just down loaded your book, “Punk’s War” on Audible the other day. It is an excellent book and plan to listen to all of your books.
Very well presented and spoken clearly. Good job!!
Soon after the incident, I predicted that, because of all the heavy equipment in a large port like that, they would have it open in a month.
Although I was off by a month, I was definitely well ahead of what other people were predicting at the time. Glad my hunch was correct! And great job by everyone involved!
I love this Channel. Experts explaining facts. No Bullshit..........
Good info. Thanks again Ward.
Excellent report Mooch!
Thank you Ward and Sal. I had seen the hammer drops but thought an Electro Magnet. I am stunned to hear San Diego based USN ships would be trapped behind the Coronado Bridge if it dropped. I was a good pilot, not because I was Chuck Yeager, but looking ahead and not in the rear view mirror as the Bridge goes down is what a good pilot is about, if you can't do that you are not a pilot. The same mind set that got us Pearl Harbor.
Love Sal!! Wealth of knowledge!
We have no leadership on any of these issues of Maritime. I did not expect anyone on my crew to do or understand my job - other people could and did, but not the crew. We depend on specialists, none of us can do it all (though most of us have to be a lawyer, a financier and a worker just to get through life). Our so called leaders are not interested either unless the ship hits the bridge. We as individuals can understand it all perfectly and we can't do anything about it. This is a consequence of off shoring industry as well as cheap ship ops where they offshore crews because they can pay them far less. And my hat is off to those crews. Its amazing how well it works and how hard they work, not how badly it can go when it goes wrong. They are stuck like we are, victims of the system trying to take care of their families (Chief Makoi said 8+ months was not uncommon and little and in some case no Internet).
Another excellent episode - well done gents.
Good stuff, gents. Thanks for the concise info as always.
As always clear and accurate information. Thanks 👍.
Superb presentation, thank you and BZ.
Safety should be our #1 value in operation, maintenance, and repair of our Merchant vessels and shipping operations.
Sabine!! This is so great!! You were already my hero but this is giving me such glee! What a fun Video idea!
So What Happens to OUR Infrastructure and How Do We Protect OUR Harbors and Bridges from this Happening Again...
There is no 100% protection. The saying, if it can go wrong, it will go wrong. It’s just being human.
You want to make a giant force field? You are talking about a pretty rare event. It's not like we design everything to resist an earthquake.
If you don't want our infrastructure to crumble, vote blue.
Thanks for the update👍
Just the thought of calculating loads and forces, just to remove overburden of cargo and bridge superstructure is beyond daunting.
One has to calculate what forces are already in play, what effects altering those forces are, lest one either cause catastrophic damage to the vessel or as bad, a sudden shift in loads displacing the vessel rapidly, causing loads to shift and likely, crew injuries.
One hasn't shifted anything yet either! Now, realizing that no matter what you do, work with that bridge superstructure will trigger a catastrophic collapse and shift of loading forces, one has to design one's own catastrophic collapse that balances and relieves forces in predictable ways. One still hasn't moved anything yet.
Now, one can begin to calculate charge placement and quantities. While reverifying all work, because you can't undo any errors.
Then, precisely relieve the loading, allowing leverage and gravity to remove the overburden, while not causing any sudden displacement of the vessel and ensuring as much of the debris as is possible falls free of the vessel and not damaging the hull.
Makes me dizzy just thinking of all of those calculations and measurements!
As for the vessel's removal, I suspect that they didn't want to use the ship's propulsion to avoid lateral forces that would be caused by the propulsion system, as she'd tend to want to veer to one side of the beam due to the force of the screw's rotation itself. Far simpler and easier to allow the tugs to push and pull her with greater predictable precision.
Hell of a job all around!
There's another emphasis on the land side to consider as well though, that bridge was the primary hazmat route through the port. Now, all hazmat has to go through the city or tack around 120 - 150 miles additional road travel to the west of the city. Used both routes with military convoys, preferred was the bridge.
I'd also add, beyond the additional stresses on the crews, there still is the stresses of continual operations of the vessel itself, as some maintenance requires downtime of primary systems, a fair amount ending up deferred during the pandemic emergency. That tends to accumulate and won't magically disappear and some failures can synergistically interact in unpredictable ways to result in sudden failures.
Still, given the mass of the vessel and the usual traffic - even in off hours, it's an absolute miracle that the loss of life was confined to just six! So, great job on the chain, from Dali through the bridge law enforcement response in rapidly preventing a far worse disaster.
Thanks, Ward.
Two of the best analyst. Thanks!
Great job guys!
I’m a Tomcat has been, like Ward, and always watch Sal. He’s fantastic, like Ward!
Amazing how little time there was. We have a saying in aviation when you have an emergency - wind the clock. That wouldn’t have helped.
The Dynamic Duo is back! Cheers!
Excellent presentation!
Nice collab. 2 really good channels.
Bravo Sal! And Mooch!
Great interview 👍
As usual --- a really great technical analysis!
Thx Ward and Sal for the Dali status overview.
An USMC F-35B crashed at Albuquerque International Sunport in New Mexico on 28 May. Pilot ejected, but was badly injured. Two minor injuries on the ground. Sunport is next to Kirkland AFB. The pilot stopped to refuel in NM on the way to California. Strange that an F-35B stopped at a commercial airport to refuel. My guess is that the F-35B refueled at Kirkland AFB, then after takeoff had a mechanical issue and tried to land at Sunport Airport. Godspeed to the Marine pilot.
UPDATE: The F-35B that crashed was being flown by a DCMA Pilot and was fresh off the Lockheed Martin production line in Fort Worth, TX. It was flying to Edwards AFB in California.
Good information
Always the best source of intel.
There is more security against those crew members from all those cargo ships from coming ashore than the millions coming through the southern boarder.
If you absolutely have to make stupid comments, at least learn how to spell 'border'.
Thanks!
A study someone conducted showed that you needed BIG tugs and they needed to be tied to the Dali to stop it from hitting the bridge. The sail effect on that wall of containers is huge. So if they still had the two (not big) tugs that got them out of the terminal with them when the power failed the ship would probably have still hit the bridge. There are not nearly enough big tugs in the US to provide escorts.
So wise , Thank You .
Fascinating video Content
Nice video.
I have been in the merchant shipping industry for about 38 years, of which the 33 as a deck officer.
During my time at sea the standards have gone more and more down. Everything is made to the limit, nothing in the back hand.
The standard in the accommodation is also getting more and more poor. Funitures are a quality you would newer have in your home, mattresses -where the seamen sleeps every night are sometimes poor, food is always on a very tight budget etc. Everything is on minimum.
The contract periods are too long. For Indians and Far East crew members 6 month is normal, and often are they extended either because the management (SYNERGY MARIME MANAGEMENT etc) wants to save money and change large numbers at the time. The motivation falls when a crewmember have been on board for too long an fatigue sets in, To my opinion 5 months should be the maximum and I would like it to be required by USCG and European authorities. If any crewmembers exceeds 5 month a new crewmember shall be on board and signed on before the vessel is allowed to leave the port, otherwise hefty fine shall be put on the managament company.
Imagine being 6 month or more on board, seeing the same people every day and eating the same poor monotonous food. Often there have not been as much as a single day off, and if any, then just a few.
Crew change in the US and Europe is complicated due to visa rules etc.
In many US ports shore leave is not possible for ships crew. Expenses for a taxi to bring you from the vessel to the terminal gate are too high, specially for Asians and other low paid crews, or the terminal transportation (bus) have a low frequency and does not fit to the work schedule on board. This is the way oil terminals, in real world, forbids ships crew to get to shore to do some shopping, get a burger or see a restaurant, or just jer some fresh air away from the vessel.
I have seen crewmembers being refused to get a shore pass, even though holding a valid US visa. The immigration officer refuse them without reason. Only explanation is: A visa gives you the right to knock on the door, but it is not a guarantee to enter US. This was also the answer to an injured crewmember I had a couple of years ago. He had to be signed off for medical reasons, and the refusal to give him a shore pass made it rather complicated to get him signed off.
Reason the DALI did not have tugs made fast to assist in an emergency situation is the price. If tug boats were included in the port fee or mandatory i.e. till after passing the bridge the situation vould have been different. Specially the aft tug could maybe have done some steering on the DALI, and perhaps the collision with the bridge could have been avoided.
Even a 100 tons tug (which is a rather big one for port manouvering) would not be able to stop a ship like DALI. My rough calculations says it would take about 2400 meters, or 7900 feet.
Ward, another great video quite informative. What a mess and loss of life. It appears it will take years have a new bridge constructed. I don't know the area from what I've heard and read this has caused travel headaches already and will continue for some time.
My guess why they didn't use the main 55000 HP engine of the DALI to help unground it could be that they were worried about the sea water intakes for engine cooling on the bottom of the ship sucking up debris and sand/mud etc.
Ward did you see Erik Prince repudiate everything that you stand for and most people you bring on your show? It was nice to see truth spoken about you and those like you and what you and those like you have down to the US military.
I cannot help but note some of Sal's copies of Samuel E Morison's 'US Naval Operations in WWII' on the bottom shelf of his book cabinet. He's got his 'Two Ocean War' ,too... Guys, I WILL pause and check out what all of you are reading. I 've gotten some great books this way, lol!
Have you heard anything about the process for designing and building the replacement?
I assume they will be removing all the remnants of the old bridge so the new bridge can use the same approach.
The design process is underway. no contracts have been awarded.
Pls explain how military ship crews operated in WW2 w/out liberty calls for long periods.
As you said - "WW2"......
Very informative as always. Mooch you shows are always enjoyable. Side bar have you seen the new Blue Angle movie in IMAX ?? Great Film.
Many big circuit breakers include
ADDITIONAL “TRIPS” from all kinds of inputs‼️
For example; XFMR low oil, loss of ground, phase in balance
On and On no idea if any of these relevant BUT I’m darn sure trips other than the handle and current where available‼️
Nice to know if such trips were involved⁉️
That's an interesting point you bring up about visas. I traveled all over the world when I was in the navy, never got a visa. I assume the US has some kind of agreement with these countries so we can get off the boat.
Bravo Zulu to everyone out there who helped in Baltimore. Especially to those in the Navy and Coast Guard.
For the Coasties, Semper Paratus isn't just their motto and guide. It's their way of life. They live to help others.
When Ship Happens and the maydays go out, civilians, police and navy all call the Coast Guard.
Great commentary. Two of my favorite commentators and fact finders
Retired Navy Chief.... Sa.... LUTE!!
