0:11 the town is called "Braunschweig" and it is in the country of "Germany"...zz
@@goofycker No, it's the Port of Brunswick in Georgia, United States. The town of Brunswick (Braunschweig) in Germany has *nothing* to do with the sinking of this ship. Look it up: MV Golden Ray.
GARBAGE SPAMMED BY GARBAGE. INTERUPPTING YOUR CONTENT TO SPEW THIS GARBAGE? WHAT THE HELL IS WRONG WITH YOU PEOPLE?
So. What actually happened.
You left us without and answers.
I just want to know how
Ads are our modern worlds CANCER :D
When I was in the navy, draught and stability was solely the responsibility of the Senior Hull Technician (seniormost shipwright aboard, generally a PO1). They handled all of the ballasting, trim, and stability calculations themselves to ensure it was always done correctly. Seeing what happens when it's left to the already very busy Chief Officer on a merchant vessel, it's no small wonder why.
Great video, thanks for sharing.
If you need to absolutely make sure something gets done right, trust it to a senior NCO.
in the business world, they have management consultants to advise on paring every bit of cost from business operations. too bad the MC's don't understand ship stability and personnel workload issues. Like the oil platform deep water horizon, save million, lost billions
Right but naval vessels have many, many more crew on board than a commercial vessel of similar size, which makes it possible to have crew members dedicated to specific tasks.
@@beeble2003 Even with smaller crews on merchant ships, making stability a 1st/2nd Eng responsibility is a much better choice than leaving it to the Chief O.
one quite important thing to do for all Chief off / Masters - Any time You do something with your ballast / cargo - print out your stability and make compare with daily ( last day ) soundings - it would give You 100% confidence. No any doubts, that work load on car carrier - is off great leve. Chief off can not sleep for days, but same time - double check and cross check to be issued. Along with that, do not forget - mass of the cargo and it's location is paramount and not always correct - which affects stability as well. ( I am not familiar with Car carrier loading and stress distribution )
Why would you just open that door in "anticipation" that sounds like opening your car door while driving cause in 20min someone will want to get out of the car.
That is what I thought too. It was reckless, and overconfident.
Yeah, a bit of an explenation of why that was done or if it was an error seems missing.
"Why are you stopped in the middle of the road?"
"I am anticipating getting to my destination"
This is a common industry practice for the pilot to give 20 minutes notice for the crew to prepare the pilot ladder, so it is ready for the pilot to disembark.
Common practice inland, the weather wasn't a factor, only the design & loading of the ship. Roro = Roll On Roll Over
Well done. You did a good job of condensing the basics of ship stability into something a layman would understand
Thanks Michael
One factor was probably that stability calculations on car carriers are not taken all that serious. Cars are "volume cargo" and don't affect the ships weight all that much (trucks and heavy machinery can only be stored on the lowest deck(s)). It is really difficult to load a car carrier so badly that GM becomes an issue.
Until you're 1500 MT short on ballast and don't know it. Then it becomes super easy.
@@johnd5398 Barely an inconvenience.
@@andrewboyer7544 wowwowwowwowwow
@Shama-Llama Ding-Dong Hey, shut up!
@@johnd5398 You mean 1500t. I guess you want to say Metric Tons, but tons are by definition metric. 1500Mt would be 1500 Mega Tons or 1,5 Giga Tons. Thats 1.500.000.000 Tons
I’d love for you to go into detail about how crews escape/navigate a near vertical ship or how rescue crews work in general. Such an interesting topic!
As far as I know, all training is based on it being a nice and calm day.
Based on what happened to the Estonia we might conclude the answer is "They don't", but rescue stuff might be fascinating, indeed.
I'll work on my character animation, and then look into topics like that.
@@tjampman Funny, but it seems like accidents never happen when it is calm and sunny. Night time and rough weather seem to be the most likely combination.
@@markfryer9880 when I did my heart start resuscitation training the doctor told us the only time she had used it was with the patient still pinned in the front seat of the car and working through the shattered windscreen, we were obviously learning in ideal circumstances, kind of like when you do your training.
Had a few friends working on the Salavge Op. It was a mess due to MARPOL and EPA, not being happy with them literally cutting a ship filled with cars into sections while in the water. But they got it done. BZ to the salavge teams.
It looked like a really complex operation.
Yep- I live in the area. I'll just say, it looked like a MONUMENTAL task....almost impossible. But they did it. They (everyone involved) did an amazing job of getting everything gone with very little , if any oil issues in the sound and the beaches. The locals are very grateful for the teamwork and results.
Not happy because thousands of tons of fuel, coolant and oil would be spilled. All those cars had fuel, oil and coolant in them.
@@afcgeo882 Not sure what you mean: you saying you're NOT happy because they averted a potentially environmental threat ? So, you would be happy had it caused damage?
@@hazor777 Happy? I never said anything about me being happy or unhappy. Do you have English comprehension issues? The OP was talking about MARPOL and EPA being unhappy, although none of that makes sense since MARPOL is an international treaty (treaties don’t have feelings) and the EPA doesn’t protect the coastal environment (the Coast Guard does.)
A lot of videos with this level of graphics end up with stupid, silly, or pointless graphics. This one expertly visualizes exactly what is needed, clearly, attractively, and without more tech or bother. It sounds like a little thing, but I am VERY impressed and pleased. Keep it up! I'm subscribing.
Thanks Vinemaple. Great to have you on board.
And additionally there is enough emphasis to add the two cups sliding off the controls 😁
@@CasualNavigation I agree with Vinemaple: I was Merchant Navy for 17 years..... mentioned this accident to some friends, who have NEVER been to sea and they could not comprehend the chain of events: Now, thanks to your video....they will. Thank you!"
I'd like to hear about the vehicle cargoship that capsized in the English Channel back 2000-ish. I have a vague memory that it contained the first shipment of some thousands of Volvo's brand new flagship (pun intended) model XC90, heading for USA. So that was fun for Volvo
I'll see if I can read up on that.
MV Tricolor, you mean?
@@CasualNavigation.Ro-Ro vessels accidents can be who topic on its own. Besides the MV Tricolor collision, the MV Cougar Ace lost stability off the Aleutian Islands in 2006. She was towed to Portland, OR where her entire cargo of 4,703 cars was declared a total loss.
@@awmperry Wasn’t there an MV Nicola that got involved too? I seem to remember a wonderful Mitch Benn song about it ;)
The 1987 Zeebrugge Ferry was quite a disaster.
Fascinating! I really enjoyed your visuals on this one. One thing I appreciate about your presentation is that you don't sensationalize these disasters. You report the facts and what was learned in a very easy to understand way. Thanks for your hard work putting these together :)
Thanks Bailey. I always prefer to present the facts as I think it helps people to learn from past mistakes.
I was one of the responders to the Ray, one of the most insane things I've ever seen. Just looked unnatural seeing a vessel that large laid up on its side like that...and seeming to catch on fire ever other day lol
These investigation breakdowns are so freaking interesting! I've never been a part of this maritime world, but I find it completely fascinating. I'm so glad that you take the time to share this with everyone! Thank you!!!
As expensive as it sounds it's still better than many other crashes where there were lots of casualties.
It is great that none of the crew members died during this accident. Well, great if you are not the owner of the ship (or maybe the insurance company). They probably think otherwise but still... human life > money.
Are you planning in any of your future videos in the "Maritime disasters" series to speak about the Eastland disaster? I have seen across the internet that some of the lifesaving equipment was the cause for it but there are others that denies it.
I am going to be covering other disasters in the future. I like to keep the content a bit varied as it is more fun to make.
Even if Insurance and shipping companies were heartless and didn't care about human life (they probably do though they are made of human beings as well), they would still care about deaths because they would likely be paying out death benefits to the families of crewmembers due to negligence.
Not to mention the public relations nightmare.
Always nice to hear about a shipwreck that doesn't include the loss of human life though!
"human life > money" Unless there is a pandemic going on, then far right nutjobs will happily kill you to avoid wearing a piece of cloth...
I observed this drama closely from the first news reports on Day One until salvage was recently completed. With a lifetime of engineering experience, I found it absolutely outrageous that someone somewhere was able to dictate that the ship had to be cut up and towed away in pieces. That method obviously was chosen to achieve the very highest cost of salvage possible, along with maximum damage to the local environment. It's like no other option was ever even considered. We saw with the Costa Concordia wreck, for example, how a huge ship could be uprighted via parbuckling and towed away intact.
The Ray could have been turned upright too and floated away. But no. Costs were not a consideration. Even the environment was not a consideration. Out-F***ing-Rageous!

Thanks for this insight into just how complicated marine commercial transport can be.
Boy, imagine how little people actually know about how goods and services get around the world in an increasingly consumerist world. We just take it for granted. I never think about this stuff much unless a ship plugs up the Suez Canal or an Exxon Valdeez runs aground and dumps oil all over the place
Agree. It could have all been avoided by people buying cars from their local dealership. But no, they order them online and cargo ships like in this video need to go all around the world.
Buy cars locally!
@@Kevin-bl6lg How do you think cars reach your 'local' dealership? The dealer builds them in his workshop?
Even if he does, the parts come from all over the world, that's simply what's most efficient. You think profit-seeking capitalists are shipping stuff halfway around the world for fun?
@@Kevin-bl6lg You are the person the OP is talking about.

I just have to say that I have been watching Casual Nav for quite a while now and Your content are literally Maritime training center standards love it.
Really interesting case study, and a really well presented video. I do have an issue with the idea that the fault was with "one small clerical error". I'm not at all familiar with the shipping industry or with nautical engineering, but I have done a decent amount of work on failure/anomaly investigations for spacecraft (including a few human rated spacecraft). To me the failure happened way before that clerical error, when they defined the Concept of Operations (ConOps).
Sure the proximate cause was a clerical error, but the ultimate cause was allowing a single point of failure to hinge on a fallible (probably sleep deprived) person entering mission critical numbers into a computer by hand, with zero oversight, redundancy, or fault detection. If that is really the only way to do it (and of course it isn't) then a whole host of risk mitigation elements need to be baked into the hardware, operations, and procedures to make sure this really easy to make mistake doesn't seriously endanger several lives and cost $250M (nevermind the potential environmental and economic impact).
But obviously this shouldn't have been a single point of failure in the first place. Before the vessel ever set sail, an FMEA (Failure Modes and Effects Analysis), should have easily caught this obvious point of weakness. I am not a GNC expert (my area is propulsion), but my understanding is that in aerospace, a LOC/LOM risk like this (loss of crew, loss of mission) would be handled by multiple redundant flight computers voting to make sure they agree. On top of that (at least for propulsion applications, idk about other systems) a FDIR (Fault Detection, Isolation, and Recovery) system should be overseeing the calculations, system settings, sensor feedback, and other stuff to make sure everything is ok and make emergency corrections. Also, [additional engineering gripes...]
I get that ships are not spacecraft, but you'd think when the likelihood and consequence of a risk are that high, some degree of risk management would be standard practice. Risk is unavoidable, but vessels/companies can't be this unprepared for it or this blind to it.
So if the program was set up to only load the data for an empty ship (no ballast, no fuel, no potable water, no cargo), and then the loadmaster has to enter everything else? If something is missed on being entered then the system alerts that the ship is not safe to travel.
Similarly, an angle meter and timer is linked to the calculations from the program, where it counts how long it takes the ship to return from upright, and compares that time with the calculated values. If the two times do not match, it will throw an alarm. Depending on complexity, this system could even spot potential reasons for the numbers to not match that the loadmaster can double-check.
You're not going to get ships to fit multiple redundant computer systems. It's necessary in spacecraft and aircraft because things move so quickly and they literally cannot fly without the computer systems. With a ship, there's usually the option of stopping and thinking things through. But I completely agree with your general analysis that they had a ton of unnecessary and apparently unassessed and unmitigated risks inherent in their operating practices.
@@beeble2003 Well, in this case they didn't stop and think things through! They never do because they have to keep to their schedule. I also noticed that the ship kept on increasing speed and didn't attempt to slow down for the 68° turn to starboard and the Captain seemed to have forgotten that he had ordered the port side pilot door opened long before the pilot was due to leave the vessel.
@@toddkes5890 While I have zero experience with ship operations, I do know that they get pushed around by the seas in non-calm weather and it was noted in this video that the weather was calm. So in calm seas measuring the return to upright would work great, but what happens if the weather is not so calm? Would this still be able to accurately measure the ship's stability? Could that be why it is not available or used?
@@LexipMedia The double-check would be done in port where the water is calmer. Also, I assume that if the water is enough to push the ship around then the crew would notice and take that into account.
Me and my wife visit Jekyll every few months and we saw the progress of the salvage operation over time. It was pretty dang interesting and neat to see why it happened
Nicely visualised incident! And I dont want to be the person that have typed in the wrong numbers in that PC to cause a $250Mio loss. Imagine that. But mistakes always happen, a system should account for that. So I wouldnt blame that person but the systems designers instead.
Thanks Tim. Glad you liked it.
Yeah, when 250M depends on one brainfart, its bad enough. When you have a system where the crew repeatedly rolls for that brainfart, and they need to fail that check only once to cause 250M of loss, thats on the system designer.
@@nazamroth8427 yeah, the "CYA engineering" can drive me nuts. Basically, the engineers make it so that a human has to manually enter in all of it, that way if something goes wrong, they can blame the person rather than the design. Price is also a big factor, but a lot of it is liability.
They do the same stuff with alarms. I've used some equipment that has various alarms lighting up and sounding every 30 seconds or more during normal operation. One machine even had a door open AND a door closed alarm, so you constantly had a flashing alarm, no matter what you did. It's just lazy engineers trying to protect themselves from liability by making the sensors laughably sensitive. It literally trains you to ignore the alarms, since there's ALWAYS an alarm. Then one day, something does go wrong, and they point the finger at the operator for assuming it's a "normal alarm" (the concept of which defeats the point of alarms in the first place). "The machine logged the error and it triggered an alarm, what more could it have done?"
@@MatthewSmith-sz1yq In a Warhammer book, there was an inquisitor who constantly operated in tainted areas. His ship had a taint alarm installed. He repeatedly bemoaned its existence and asked for a non-taint alarm instead, because that would actually be the unusual event anyway...
I heard he had to pay it off of his salary. 25 dollars every month, at least!
As someone from St. Simons I’ve been waiting a long time for this video. Thank you for posting!
Thanks. I'm glad you liked it.
It's interesting hearing about a naval accident where mostly the people involved did their jobs properly and responded professionally. An expensive incident, but no loss of life
When I was visiting st. Simons Island I had a chance to see the Golden Ray while it was still wrecked
I don't know how this got in my suggestions, but thanks for making naval stuff both interesting and understandable to a total layperson with no special interest in the subject.
Very imformative and thoroughly entertaining. After the 2 38° turns I immediately knew the 68° turn would be the one to bring her down. Ashame about the accident.
Edit: I originally wrote the wrong angle. fixed.
As soon as i saw the door open on the port side i saw it coming, just not sure in what form
@@joshuacheung6518 It's always the bloody doors that bring things undone. Several car ferries have come undone from their bow or stern doors not being shut properly and the ship rushing to get back on schedule.
I think Chief Makoi mentioned the reason for this might have been that they didn't want to get the water by the dock and then have to run the water treatment plant, but I only go on sailboats so I can't judge how realistic this is.
That sound weird, because, I really struggle to believe they would depart without a seaworthy condition.
Besides, if they have ballast water treatment system, it should not be any trouble to take ballast. ( I am not entirely sure, as I never sailed with BWT systems, but if they have that I don't think they need to replace the ballast water in open seas)
Coming from the airline world (which also has strict requirements for weight and balance and other aerodynamic performance curves) it was interesting to see similar things in the maritime industry. Should have been able guess that all that was in place, but I’ve never heard it explained before. Thanks!
Always been wondering what had happened. Great video!
Thanks CubickProduction. Glad you enjoyed it.
I live in Jacksonville Florida. I've worked at the Brunswick Port more than once. This was such a crazy event. Hell of a sight to see such a large vessel on its side. Great video sir.
I am not into ships, but I do love physics. Your summary and video are outstanding.
Thanks Blaine
Apropos of absolutely nothing, I love the way the heeling animated ship has what can only be described as a truly startled expression!
Really interesting and very well done, with great illustrations and fantastic narration!
Been years since I learned about 'metacentric height' and all that, but this brought a lot back. Great video. Surprised though that captain or some senior officer didn't notice how it was so soft it was handling, but then it seems they didn't really have a lot of time to think about it as they navigated the channels and were looking for the next turn.
When I was a chief mate, one of the first things when I got onboard was to check TPC graph (tons per centimeter, it shows how many tons are needed to be loaded to the ship to immerse it 1 more centimeter, calculated differently by the difference in the trim of the ship). After loading, even a 5 cm difference in mean draught made me freak out and triple check everything, but sometimes you just can't find the cause, it can be the constant weight on board, it can be that the cargo weight was declared incorrectly, it can be that the bosun performed the ballast sounding carelessly. Still, if the difference amounts to 1500 tons, captain will be notified that's for sure.
Pick up your cross and follow Jesus! The world is quickly headed for destruction, and sooner or later you will have to sit at the judgement seat and give an account for your actions. Belief in messiah alone is not enough to grant you salvation - Matthew 7:21-23, John 3:3, John 3:36 (ESV is the best translation for John 3:36). Call on the name of Jesus and pray for Him to intervene in your life! - Revelation 3:20.
Contemplate how the Roman Empire fulfilled the role of the beast from the sea in Revelation 13. Revelation 17 confirms that it is in fact Rome. From this we can conclude that A) Jesus is the Son of God and can predict the future or make it happen, B) The world leaders/nations/governments etc have been conspiring together for the last 3000+ years going back to Babylon and before, C) History as we know it is fake. You don't really need to speculate once you start a relationship with God tho.
Can't get a response from God? Fasting can help increase your perception and prayer can help initiate events. God will ignore you if your prayer does not align with His purpose (James 4:3) or if you are approaching Him when "unclean" (Isaiah 1:15, Isaiah 59:2, Micah 3:4). Stop eating food sacrificed to idols (McDonald's, Wendy's etc) stop glorifying yourself on social media or making other images of yourself (Second Commandment), stop gossiping about other people, stop watching obscene content etc and you should get a response. Have a blessed day!
What an accessible explanation to explain what happened to the Golden Ray! Thank you for this!
my heart starts pumping in anticipation and this calm, jovial sailor just spells out the disaster so calmly lol
The salvage costs actually exceeded $1 billion!
i have no idea why im here and i gain no value from your videos but i love them
I never realised I was interested in this sort of thing untill I found this channel!
Such a beautiful vessel, sad this happened
This was the first video I watched from the channel and my immediate thoughts are, you got my subscription. That was well detailed and entertaining. 👍
Wow! Leaving the pilot door open was really a bone-headed move. Even if the computer had the right figures, and everything was correct as far as ballast, closing the pilot door just seems like something so simple and obvious to do.
So the Captain should had someone someone stationed by the door so if the ship starts heeling too far over, that person slams their hand on the emergency-shut button and the door closes ASAP?
@@toddkes5890 The pilot door should have been closed after the boarding. However, having an extra person stationed to be responsible for the pilot door closure would be brilliant thing to so nobody overlooks the closing. I like the way you think.
@@indridcold8433 Actually I just found out, the problem was not not only that the pilot door was open, it was that they had 2 water tight doors open from the pilot boarding area into the ship allowing water to flood deck 5 and the engineering passageway incl engine room and steering gear room.
Vaasa: "First time?"
@@tjampman It sounds like the ship was being ran in the most sloppy of ways.
what’s crazy to me was i could see this from my back porch. it literally was right there. so glad everyone made it out alive but man it was cool seeing that crane
As I've worked on vessels before... It's unusual to open a door an just leave it thru such a long trip. I don't understand why he did that... Our captain wud only open those doors when pilot boat was coming.... WOW !! ✌🏼💗😊❣️
This is why it pays to have people check your work so obvious errors get caught. Great presentation and just enough theory to understand without bogging down in details.
In the IT world this is called "paired programming", in the diving world this is called "buddy system", we need more system like this to be implemented.
8:16 I'm not sure all the cars would have stayed in place with a 83° angle
Awesome channel btw !
Thanks bigpig
Dont know the requirement for ship, but on trucks, they shouldnt move if they are probably secured, of course you have much higher G-Forces on trucks.
@@jonasstahl9826 The do get lashed to stay in place, but I doubt the lashing are strong enough to hold them in place when the ship is capsizing.
I found a small video here,
ua-cam.com/video/bOtTmvGhr4U/v-deo.html
showing how they are lashed, I am pretty convinced about my above statement.
@@tjampman I dont think so, the tow hook of most car is on the right side. When the ship roll to the right side, the cars still can flip over because the suspension compresses and allow some movement, but they would stay in place, just tip over to the side
That way would work if the straps had enough tension to compress the suspension. Or the tow hooks would be in the center.
That will just pretend the cars from moving sideways, but that is enough for a ship.
Wow, extensive and thorough overview of what happened to this ship. Subscribed. God bless.
Very interesting! Thanks for sharing
Thanks for watching!
Wow great discussion of ship transverse stability. Probably the most technical, but easy to understand, discussion I have seen on youtube.
Interesting video. I'd followed the story as it happened, but I appreciate the technical details on the final analysis of what happened.
Just so you know, the local pronunciation of Sidney Lanier's last name is two syllables, "la-NEER" rather than "LAN-ee-Ay". Though I'm pretty sure that had nothing to do with the ship overturning.
Cheers Drew. I'll try to remember that for next time.
I was going to mention that too, but I didn't want to make a similar comment if someone else had already addressed it. Glad I checked.
It's simple and very minor error, anyone could've mispronounced it.
@@Unownshipper Absolutely. "Lan-ee-ay" is a good guess -- it might well have had that French-style pronunciation (especially had it been Louisiana instead of Georgia). It's American English -- so many influences from so many directions it's hard to know which of the seven or ten sets of rules that each word might without actually hearing it.
As long as I've gone off on a tangent, I might as well add that Sidney Lanier was a musician and poet. One of the works he's remembered for is the poem "The Marshes of Glynn", part of a set inspired by the salt marshes of the Glynn County wetlands, which surround Brunswick. Hence naming a local bridge after him.
All of this information will be very helpful the next time you're trying to get the weight and balance calculations correct while loading your next cargo.
Nice video, but that wasn't a typo. A typo is where you intend to enter one number but hit the wrong key and enter a different one. These guys just entered the wrong data, as you explain at the end.
Love me casual navigation fridays, great stuff
Glad you like them!
Thank you for another interesting video. Have a good day from Sydney Australia 🇦🇺
Thank you for explaining what G-M is so clearly. I fully understand it now which feels awesome
Thanks for the video! Really great animations in this one - especially with the computer UIs!
Thanks Justin. This one took a little longer than usual, but its good to always be pushing to improve.
Got to see the Golden Ray salvage operation. Really a marvel how they cut the ship into sections and then put the sections on a barge before towing it to the scrappers.
Comments below add a true dilemma; on one hand is automation always correct? ; on the other hand is manual input always correct?. I remember seeing a video some years ago of an elderly cruise ship captain who kept all his charts and maps even though the cruise line he worked for wanted them gone in favor of digital automated maps. His comment was, paraphrased; With these charts I can show the younger officers how it was done and I can check to make sure the computer did not make an error!!!! Cool, double checks.
That's how it should be ideally. Humans and computers checking each other. Here it went wrong that the computer apparently didn't give any input suggesting the manual numbers were wrong.
Makes me wonder why there was no way to just... automatically have the IMACS data inputted into the stability computer.
Cool, I know diddly and squat about anything you talked about but I,learned something and am intrigued. Thanks
Great video, your animation is amazing
This level of detail is getting a little too technical for me, but I'm sure many of your subscribers crave even more...
Usually you get the balance spot on, also you can't please everyone
Maybe varying the levels of detail to see what is the most popular, before considering a split to a second channel
Your Channel is getting better and better all the time! Fantastic video
Thanks Testy
I remember flying over this ship in the inlet a few times when going to SSI airport. It was quite a shock the first time I seen it, it was there for months I believe.
A billion dollars in damages from a minor error. Crewing a RORO ship is like sailing on a big piece of swiss cheese while trying to keep all of the holes plugged, while an elephant is sitting on it.
I've heard of a running joke in the maritime world that says RORO actually stands for "roll on, roll over".
can’t believe this is the first video I’ve watched from this channel! Like where the hell have you been
Definitely should do more accident case studies! Great video!
I know it's for stability, but I've alway found the purpose of ballast tanks amusing.
You basically have to fill your ship with water...so that your ship doesn't fill with water.
On a serious note, this was a very good video. I enjoy well researched and simple, yet effective animations to help deliver the point. This video is a prime example of that.
Your animation game has improved so much. This is a really good video.
So, the title is clickbait. There was no typo.
This happened off our local tourist beach.. Pretty amazing to look at
First time seeing one of your videos, but wow, it's very well done. Great voice, very clear, and the animations and information is top notch. Thanks!
Well done and illustrated! Thank you.
Very well explained, however for the GZ curve which is in the video, you could have also mentioned the effect of turning (Turning moment lever) on the GZ curve itself for better understanding.
Some of the instrument approaches into SSI can give some really nice views of the capsized ship, super cool to see from above!
For people new to nautical disasters ROLO stands for Roll On Roll Off. This means that it has a door in the hull that lets wheeled cargo on without needing a crane. Since this makes them less water tight and more prone to capsizing the common industry joke is that ROLO actually stands for Roll On, Roll Over.
Now that's how you explain stuff to a layman. Excellent keep it going.
One of my favorite podcasts (or any show from any medium, really) is an actual play DnD podcast with a definite naval focus. Today an episode came out, and in the biggest mass naval battle yet, the sorcerer used reverse gravity on the other side's aircraft carrier-- not a modern one, it's set in 1797 but with all the classic dnd races, spells, most of the creatures, etc, so the naval air force is made up of giant eagle riders.
Aaanyway, kinda lost the plot there... the point of commenting all this was to say, the aircraft carrier was about as wide across as the spell's diameter, and much longer, so couldn't just lift it up and drop it to break it. Instead, they cast it on one side of the ship, with intent to capsize.
The mechanics here are obviously somewhat different lmao, but it's similar enough that I was excited to share this video in the fan server for the show. I think other fans will find this an interesting watch as well, but regardless it's such good timing and I'm very glad this was in my recent memory as I listened to this new episode. 👍👍👍
Also very important that the Chief Eng supplies accurate (soundings) fuel and lub oil bunker figures to be fed into the stability computer.
RORO ship means roll on, roll off. Basically it had it's own ramps and you could drive the cars on and off easily. Dad was an auto carrier at that port for years
Glad I stumbled across this!
Reminds me of the NASA engineer who got units for burns mixed up and a probe got fired off into the Oort cloud rather than a closed trajectory because of excessive burn.
Difference between a Boat and a Ship is it's lean during a turn. Boats lean inward, ships lean outward. That's why Submarines are called boats, they lean inside.
I'm ex Royal Navy and my ship HMS INTREPID was and lpd. Landing platform deck, an assault ship with a well deck that flooded to let out our landing craft carrying marines and vehicles. When the landing craft were back on board and the well deck had no water in, we were a top heavy ship. No matter how much ballast was taken on, it rolled like a bxxxxxd. Especially through the bay of his day on way to the gulf of in the North sea on way to Norway. Many a time as a young 17 year old Bosnia mate, on bridge at sea, I thought we were going over and not coming back up. But she seemed to kick her ass, like a wiggle and slowly but surely she would come back up, just in time to roll back to port/ starboard on the opposite return. Great ship that I left in 1989 for a post draft to HMS NELSON, main gate.
Sorry about the spelling. Didn't have spell checker on.😇
I love the accident report episodes. We can't get better if we don't know what goes wrong.
As a project manager, there are people you work with that has an amazing memory and attention to detail. Most people does not... those are the cheap employees that can not go any further, but no one pay attention to those things when hiring, they just hire the cheaper. This is what happens later.
Impressive - the thing sailed right across the middle of Puerto Rico.
cant wait for your vid on the Roro that sank in the Atlantic in March 2022
When you have a really BAD DAY at work
Great video thank you, just discovered your channel, liked and subbed! I'm really surprised there were no sensors that detected water coming in through that open door. An alarm should sounded and they would have shut it. Computers are now clever enough (by reading the planned route) to forewarn the crew in cases like this. For example lets say that a door on the starboard side is open and the computer can see that a starboard turn is coming up 5nm ahead - it will alert the crew to close the door. This sort of thing.
Ro-Ro carriers are infamously unstable. Hoegh Osaka had a very similar loss of stability and near-capsize onto Bramble Bank near Southampton in 2015. In that case the loading conditions were unusual as the ship was off its usual route, and no proper calculations on stability were undertaken before the ship sailed. In fact the Chief Officer was undertaking calculations, sounding tanks and ballasting the ship while the accident happened.
Another good one, thank You Sir!
There were great views of the capsized ship and salvage operation from the Jekyll Island fishing pier. Still, I’m glad it’s gone now.
I am reminded of the car ferry that left with the bow doors wide open... The stability calculations altered each second the ship moved forward. (Think balancing a tea tray with a pint of water poured over it!)
If it weren't for your channel, this subject would suck. But you make it not suck. So thanks. Interesting stuff
Fascinating video. Every little detail can matter
Damn, 1.500MT ballast. Ballast tanks have small KG because they are near the keel. So the final KG was falsely reduced in their calculations.
Haha, I did take a little artistic license with those screens.
@@CasualNavigation they were 100% accurate, im currently studying in merchant marine academy, last semester. I've studied exactly this.
One who knows what we're really talking about...
So glad everyone made it out safely.
"What's the GM on this thing" lmfao
Always well done and very informative!
It's funny how now with the youtube timeline of most watched moment, you can so clearly see how everyone loathes the advertising, the entire video is flat, then you just have mount everest at 6:14 lol
I had a horrible feeling that the cause would be the sea water ballast still being assumed to be there in the calculations, when it had been pumped out to access the harbour.
I remember going to Jekyll and going to the peir, and I saw the massive ship on its port side, with a massive yellow arch over it on a barge.
Excellent production
