The clip was lost... And no one thought to order a new one......
No thanks, i've got enough Temu crap already
Remember the age of loot crates?
Like 5 fucking years ago
No.
Fun Fact: The ship "RRS Sir David Attenborough" is actually pronounced "Boaty McBoatface"
lamest fucking joke name ever
The name Boaty McBoatface ended up being given to one of the research vessels remotely-controlled submersibles (which on a side note is yellow).
@@Titanic-wo6bqIt's yellow? Needs crew quarters.
@Titanic-wo6bq these are just missed opportunities...
I personally always refer to Attenborough as Sir. Boaty.
The answer to "How did X happen to Y if it is brand new?" is always "because it is brand new"
signed: a safety engineer
I'm far more nervous testing something that's never been used, than something that's worked correctly 500 times.
At least they discovered this off the coast of Mull and not during an evacuation in a storm off the coast of Antarctica.
I considered that as great luck, not bad luck, had this not happened, it might happened in real emergency.
Degraded in 18 months, doesn't sound good.
I love that the moment you mentioned her name, I immediately knew which boat that was. Even if she goes by a different name, she's still Boaty in our hearts.
Wasn't that the same ship that was voted to be named Boaty McBoatface?
It is called Boaty McBoatface, the sign-writers just misspelt it.
Yep that's her name, she doesn't appreciate it when you mispronounced it.
yes, they named one of the remote drones boaty as a concession.
Took me a while to figure out this vessel was at anchor, not "a tanker".
Also took me a second to get that it's a "royal research vessel" and not an "oil research vessel".
Naming an oil ship after Sir David Attenborough would've been pretty fucking bad lol
Same. I thought it was kind of weird that a research ship would be moonlighting as a tanker, I only figured it out the second time
This is why its bad luck to rename a ship.
Squalus?
they had queried the world for a name, and the world had spoken
_they ignored the response_
I kind of assumed they work like pinecones, they fall off when the season is right and eventually grow into another container ship.
If only they had called it Boaty McBoatface this would have never happened
RIP boaty mcboatface
Never. Call it boaty so much that no one acknowledges any other name
Check it's Wikipedia page
Boaty McBoatface!
😊
This highlights the benefits of having OEM engineers attending as part of commissioning, and owner/crew training. Even though they can be expensive, it may save time, money, and even lives in the end.
And put the people that install it in the boat during the first test.
@@NotALot-xm6gz that actually leads to a problem if they fucked up the install and then all get killed. There's nobody left to ask about how they installed it so you have to reverse engineer the install issue.
@@ctownskier OK, just the manager goes in the boat.
If anyone is curious as to the origin of 'Boaty McBoatface': Boaty McBoatface was the most popular choice for a naming poll that was conducted to name the ship, winning 33.16% of votes. Boaty McBoatface was originally jokingly suggested by former BBC Radio Jersey presenter James Hand; Boaty McBoatface quickly became the most popular suggestion.
Despite the name not being chosen, with the ship being named after naturalist Sir David Attenborough, the name ended up being given to one of the research vessels remotely-controlled submersibles. (On a funny sidenote, Boaty McBoatface is coloured yellow.)
Despite not winning as the name of the research vessel, as nantogeass said in a comment that was sent 2 hours ago as of typing this, it'll live on as Boaty in our hearts.
It really demonstrates the importance of drills…
Nothing bad happened because it was a drill. The mistakes was founded and they will be corrected ASAP.
Drills save lives.
Nothing bad happened because the people inside the lifeboat were lucky.
That could have easily ended in serious injuries.
@Jehty21 And they were in an ideal spot near the coast in calm waters, during the day.
@@dragon_nammi So, since they people inside were not hurt, I assume they were buckled in?
@DugrozReports Not sure they were secured since this source doesn't disclose that. But if there were stormy conditions out at sea, at night, I doubt they wouldn't have suffered critical injuries or death. Or be lost entirely.
I'm saying this was the best case scenario for a critical failure to happen in.
Cutting corners in inspection safety. Nice.
I attended an offshore survival & firefighting school in the late 1980s and was told a cautionary tale about a safety instructor on a rig who always gave the life boat release mechanism a couple of pumps during the safety demos he gave. The release mechanism was either pneumatic or hydraulic and needed X number of pumps to release. What the safety instructor had forgotten was that the pressure he was putting in wasn’t venting anywhere and his “couple of pumps each demo” eventually released the lift boat from the rig without the folks inside being properly secured and some where seriously hurt.
Big oof!
Please tell me no Boaty McBoatface was harmed during this incident.
Boaty is doing just fine. It's currently doing research sampling water for DNA (scientists recently discovered that you can tell what life has recently been in a section of ocean by pieces of DNA that it sheds in the environment, so I assume this is related to that).
This is a clear demonstration of an increasing problem across many industries. The nature of the problem is fundamentally that responsibility shared is NOT responsibility doubled but responsibility halved. So many different agencies and departments were involved that it was possible for everybody to develop slopey shoulders and palm responsibility off to everybody else. Having read the report I get the impression that a loaded gun is being pointed at the mate while the shiney arses just walk away and look for their next 4 or 5 star meal at the expense of the shipping companies.
Diffusion of responsibility gets stronger, the more parties/people get involved.
"Missed opportunity" is so mildly put, this is a straight fuckup by all responsible parties.
Can you imagine the state of the ship since the company that owns it simply turned off all the maintenance notices? That's straight up gross negligence
Not really. It's safety 101. Someone at some point will fuck up. In fact that happens quite often. The trick to having any degree of safety is to make sure there are tons of opportunities to catch the fuckup.
the company that owns it? you mean... the united kingdom's government?
So because there was too many defects, they decided to stop doing maintenance? How much above the law you have to be to think that way.
You can only do so much at a time... I would assume they disabled the alarms/alerts as they were working their way down the list. If that isn't the case, then I'm glad I'm not going on any boat they own!
trying to do a backlog of 12 months of maintenance ASAP is difficult enough without constant alarms I'd asume
This is a great illustration that too many warnings equals no warnings at all. An important thing to keep in mind for designers.
That remote wire is an incredibly clever mechanism!
The front fell off.
- John Clarke (iykyk)
That's not very typical, I'd like to point out.
@@euanduthie2333 move the thing to a void,where there isn't anything else.
Well at least a wave didn't hit it...
iykhtgyk
Pretty good engineering that despite all the screwups the lifeboat successfully deployed. I assume the animation was incomplete and the boat properly righted itself. Unless the "modification" for the bigger clip wasn't sealed and it flooded. Of course thats believable too.
Yea arent they supposed to be self righting or is that only within limited parameters/conditions?
@@MattH-wg7ou I'd like to know this also. EDIT: Another comment stated it did right itself.
I worked as a mechanical fitter in cammell lairds where the ship was made. I was part of the repair on the Davits
I love the section on the chain of failures that lead to the accident
It's a good thing they decided to do lifeboat drills in port, then!
5:21 "... but it does really serve to show how dangerous lifeboat launching arrangements can be..."
Great to know that the option of last resort, which we rely on to save our lives when everything else has failed catastrophically, is, in fact, super dangerous.
Would you rather swim?
@ShadowDragon8685 Nope, I'll still take my chances with a potentially dangerous lifeboat launching system, but my point is that the situation isn't great.
@evanranshaw4659 if you're having to evacuate from a sinking vessel, the situation is already a great deal worse than 'not great.'
Remember, they have to balance a safe and smooth lifeboat launch in calm conditions, with the possibility that the ship is going down in the worst conditions imaginable, up to and including being torpedoed by a hostile power. The boat *has to launch,* or it cannot possibly be of any use to anyone, except maybe tearing free of its davits five hundred meters down and bringing its occupants' remains up to the surface to possibly be buried by their kinsfolk.
But yeah, the lifeboat tearing free unevenly, not launching properly? That's a pear-shaped failure and someone hopefully got reamed for it!
@ShadowDragon8685 Agreed on all points, although I think that lifeboat would probably implode well before it got to 500m. It would depend on the leakage rate vs the rate of descent.
Those fully enclosed lifeboats tend to be fairly well sealed, but they will have ventilation. On the other side, heavy objects (such as sinking ships) move downward alarmingly quickly underwater, once they've left the surface. The exact rate would obviously depend on the terminal velocity of the object in water.
Another thought I had, but haven't yet voiced, was that the fully enclosed lifeboats are typically self righting, despite the impression to the contrary that one might be left with after watching the animation in this video.
If you strapped in immediately upon boarding, that type of fall, though not fun, should be survivable (provided other people and objects inside don't turn into missiles).
@@evanranshaw4659 TBF, I did just pull 500m out of my aft. Point was that lifeboats that couldn't launch properly not-infrequently tear free of sinking ships and float to the surface because they're designed to float at all costs.
And yeah, self-righting would be a factor; as you point out, if everybody aboard were strapped in and there were no loose objects to become falling hazards, such a launch... Well, you'd be being checked out by medics, but you might not even go to hospital.
The boat formerly known as BMBF.
It's still her name, the painters just didn't get the memo.🤣
I’m baffled to why the constructor inspection sheets did not include a detailed check of the lifeboats.. insane.
The Sir David Attenborough was supposed to be named Boaty McBoatface due to it being the most popular in a naming pole. The government decided to intervene and call it the Sir David Attenborough and Boaty McBoatface will be on a submersible on the ship.
*poll
British government trying not to act like arm bands challenge - impossible! - gone wrong!
That’s a huge list of things that went wrong. I wonder what else they missed.
I'm surprised that the lifeboat does not self upright it self in the water
Are you sure it doesn't? None of the reports say.
Whats your source?
@@jort93z The animation in this video suggested it didn't. Of course, the animation is not necessarily the same as the real world.
@@AnnaNicole.Well, they might simply have just guessed. What are the animators supposed to do other than guess if they didn't know?
Since the narrator didn't say it, I'd assume they don't know.
There is a lot of stuff that's missing from this video including other problems they had before the incident and the fact that it wasn't just the maintenance of the pin, it was also manufactured from the wrong type of steel. The aft hatch on the vessel was ripped off during the fall to the water. The report says "The lifeboat became completely submerged and water started to flood through the aft hatch opening before the lifeboat righted itself and came to rest, floating on an even keel." This story really isn't an accurate representation of what actually happened.
Cutting corners from a British shipyard? No surprises there!
At first I was like : "What a cleverly streamlined device."
And then it went "OMG! There should have been separate controls from those."
In a textbook case of "Streamlining may be smart, but it also has to be wise."
Well at least the front didn't fall off...
Learn about the bathtub curve. New things will have initial reliability issues. Especially complex, hand-built systems of systems. That's what warranties are for; get them sorted and you'll have good reliability until things start to wear out.
A lot like the Augur TLP accident in 2019. The OEM lifeboat inspectors said 'hey this cable is corroded' and then went on their way without fixing it or or making it clear that they hadn't replaced it. And also hadn't replaced it every 5 years like they were supposed to over the last ~20 years. About a month later 2 people, who were standing in the lifeboat when the rear hook detached and the boat fell 80 feet, died.
This reminds me of FPS Auger lifeboat #6, without the casualties
Boaty, looking well.
Missinstalled lifeboats and untrained crew with a wrong operation manual. Wonder what would have happened in case of a real emergency, in freezing waters, and in harsh weather.
(probably : many dead people).
Makes a Liberian flag carrier look like the epitome of seaworthiness.
I didn't know Boeing made boats, too...
Definitely not Boeing, they actually remembered to install the interlock pin at the factory!
Astonishing and expensive incompetence
Great video!
~7:00 "This ship is riddled with defects - let's suspend safety checks"? Wow!
I guess given the choice between a defect causing a lifeboat to unintentionally launch early or a defect preventing a lifeboat from launching at all, the former is preferred.
The pin degraded that bad in 16 months? Did they order it from AliExpress or what?!
It was in fact made of the wrong steel. He also didn't mention the boats rear hatch getting torn off and letting a bunch of water in before it righted itself.
I like these accident explanation and retrospective videos.
"I'm gonna sue you out of existence."
Duties of inspectors in _many_ applications, especially those hired by helpless individuals like homeowners:
1. Collect fees. 2. Come up with "something", generally meaningless, to justify existence (this is in Chapter 1 of the government employee handbook). 3. (Bonus/extra credit): extra "silent" income, for you know.
Finallly, XYZ. *(not a number because it doesn't exist)* Safety and consumer protection.
I’m retired now but the quarterly test of launching and recovering of Lifeboats as required by regulations was viewed by the people involved as one of our more dangerous undertakings.
What about a video on the Amoco Cadiz shipwreck? Would be amazing!
I love the perennial naval tradition of wanting lifeboats to be easily launchable, but not *too* easily launchable
Comes down to the age-old advice: pay attention to what needs attention.
Why is that pin even made from something that can rust? Couldn't it be chrome plated, made from stainless steel, etc?
Because plating can be damaged allowing the base metal to corrode and stainless steel isn’t. More “stain resistant” but under salt water conditions it will still corrode. Any other option is either too weak or too expensive for the application. That’s why maintenance checks are supposed to be done regularly.
Yeah, chrome/nickle plating is pretty useless for parts like this, where you have metal on metal sliding and also seawater. There are stainless alloys that can tolerate marine environments though. Downside is they often are significantly more expensive to manufacture, and can still rust under specific conditions. Therefore it is common that components are just made from carbon steel, designed with allowance for rust, and replaced at regular intervals.
Stainless steel is also less strong
It was supposed to be. But (either due to the yard or the manufacturer being cheap) it wasn't.
I'm sorry, but 16mo for such a critical part of an emergency escape solution to become non-functional due to corrosion seems like more of a design oversight than a maintenance oversight.
That part should be metallurgically designed to last a century, or at least be made out of some composite material that can match or exceed any strength tolerance needed.
This was the biggest shock to me.
It was supposed to be. But someone, somewhere cheaped out.
It was made out of the wrong steel type, also the aft hatch got ripped off and the lifeboat started to flood before it self-righted.
NORMALLY, it'd be in a better condition, if it was made as expected...
In the end something did break the chain to a serious accident, and that was the drill itself. If it hadn't been for the training launches, many of the defects would have gone unnoticed. Some would have probably been caught if maintenence was resumed at some point, but there would have still been a risk of the lifeboat failing when it was needed the most. (And I hope they checked the other one too while they were at it after this incident)
16 months for a locking pin to degrade seems like a very short lifespan
Lifeboat accident story. Was working as 3rd mate on a tanker, we were undergoing annual survey by our classification society. Myself, the 3/E and an AB were supposed to launch, make a loop, and recover the starboard (enclosed) lifeboat. Surveyors, Capt and others watching from the deck. Launch and sail in circles goes good, but we can’t get the release hooks to reset. I’m working on the aft hook, the engineer was forward and the AB on the lever. I hear a splash and a swear from up forward. I think maybe he dropped his channel locks overboard. Then the captain’s voice comes over the walkie “hey Steve, you wanna help the 3rd back into the boat?” At which point the AB and I realize the splash was in fact him going overboard, and we rush forward and haul him back onboard. Only casualty was his pack of smokes…
so, someone replaced a missing piece with a part that is "just like the original, it just needs a bit of work"
some things never change.
in aviation, this is called the swiss cheese model. It fails me why they substituted a different bracket rather than just order one of the correct specification.
This was even the 'swiss cheese model' This was more a case of RTFM/
Except they had the wrong manual.
Who would win?
A) Lifeboat manufacturer who employs highly skilled designers to create a reliable and robust lifeboat launching mechanism & maintenance schedule
B) MONKE making changes to design and ignoring rules
In the list of patrons at the end of the video, it looks like there's an encoding problem with the name between Daniel Klyk and Steven S. ♥
No! Not Boaty McBoatface!
Don't worry, Boaty Mcboaty Face the _submersible_ is fine!
I really hope there was a fresh change of underclothes available to the sailor inside the rescue boat.
Collapsible lifeboat B IS THAT YOU?!?!
Can you do a video on self discharging bulk carriers
What occurred was even more dramatic for the crew....
" ...Confident that the day’s mishaps were over, three crewmembers entered the lifeboat and sat in their assigned positions, with the third officer taking the helm, a seaman grade one (SG1) alongside him and the science bosun in the bow. But as preparations were made, the crew missed a crucial detail - the remote-control wire was not fed into the lifeboat.
The third officer stood up, opened the hatch, fed the wire into the lifeboat, and sat back down without refastening his seatbelt. Pulling the remote-control wire to trigger the lifeboat deployment sequence proved useless, until the third officer’s colleague, the SG1, got out of his seat to pull it a second time.
This triggered the incident. As the davit arms began to move, the winch system released the lifeboat falls prematurely, causing the boat to crash to the deck. But catching on the still-extending semicircular davit arm, the lifeboat rolled over until it was on its side, throwing its unbuckled passengers against the wall.
As the forward suspension ring released, the lifeboat veered over the deck edge bow-first; the aft suspension ring ripped off the aft hatch, and the boat plunged into the sea by the head, hurling the SG1 into the lifeboat’s nose. Water flooded into the hole where the hatch had been, submerging the three crew. The SG1 was thrown to the floor of the boat as it righted itself, discharging the seawater. ...."
www.imarest.org/resource/lifeboat-accident-on-rrs-sir-david-attenborough-lessons-learned.html
It sounds like the SG1 might have been seriously injured... And so it also demonstrates another important lesson: always do your seatbelt up!
Hey, could you cover a video on the Pendleton Rescue? I'd be happy to give details!
*Boaty McBoatface
YAY FINALLY
Theoretically it "successfully launched with issues" So we know that escape is possible if system isn't maintained or damaged. Also, I wonder why they dont use plunge system like on cargo ships?
Boaty McBoatface!!!
Better that a lifeboat fell of than the front fell off.
This is why you test! Test successful.
A great video that exposes a fatal flaw in the system!
OK, am I the only one to question the material used for the hydraulic interlock pin?
I am a retired U.S. Coast Guard Marine Inspector.
The use of a material that is subject to corrosion for such a critical part is unconsionable. The manufacturers reliance on a properly executed PMS system is pure folly. The suspension of the PMS system by the owner underscores this folly. British mariners are well known for excellence in operational seamanship. It appears that British vessel operating companies are more like U.S. Big Business, "Let's save a few pounds by not doing what we should."
What if a ship is temporarily unneeded, and placed in lay-up status for an extended period? Or, GOD help us, what if a vessel is sold to a less than reputable "Flag of Convenience"?
The pin was made of the wrong steel (idk wether that was a manufacturing issue or the yard being cheap). And they had turned off the PMS because it was re-issueing the maintenance calls. It literally issued them 16 months of maintenance orders and kept adding more for the same thing, so they turned it off while they "went down the list" so that they could fully wipe the system and start fresh.
Was that life boat Boaty McBoatFace?
No, Boaty Mcboaty Face is a submersible.
Boaty gang rise up
CQD CQD CQD this video is so good
boaty mcboatface
It turns out this occurred because they didn't name it Boaty McBoat Face
Better off the coast off Scotland than in the Antarctic!
Casual Navigation could you do a video please on why only small speed boats and some passengers ferry are catamarans and why no big crude oil tankers are catamarans even though catamaran are usually faster
That ship is Boaty McBoatface!!!!! Who is this David imposter????????
Short answer: Crew didn't have time to do all maintenance - meaning owners didn't staff enough crew for the workload in order to save money. typical
The owner was the government, so it’s incompetence, not greed.
Also the manufacturer fucked up, and used the wrong steel, too...
If i had a nickel for every time an accident was caused by poor maintenance procedures, I'd have.... A lot of nickels.
You'd be fairly rich.
Does it realy need pointing out that if you make a system to allow a launch test from outside the lifeboat then you havent actualy confirmed that the remote launch works!
Well it’s bad luck to change a ship’s true name.
2:52 HOLY *smokes* your level of Detail Now O.O Wow. That was what, 4 seconds :o Cool stuff man, long-time *subscriber* :) The Knife is here. You are our Advisor for Heavy Naval Shipping 😏👉 Now you’re refining an edge 😑👌
A colostomy of errors .
It wanted to save it’s own life that’s why
I like terra firma. I like it just fine.
The simple solution here is to eliminate life boats altogether.
Short answer: gravity
I still find it very weird that any safety pin could corrode within 16 months
Seems off if you'd have to replace that every single year
Improper metallurgy. They don't know yet who in the production line cheaper out resulting in the bad pins, but they.are looking *very* hard for them!
They will now.
Dont rock the Tanker baby
Am I correct in thinking these are self righting lifeboats? Did it right itself, or was the graphic illustration missed that bit? For such an accurate channel, I can't imagine you'd have missed an opportunity to demonstrate that these boats to self right. 😊
It self righted, the animation just didn't run long enough. And this was despite the fact the rear hacth got torn off, letting in a ton (literally) of seawater! (Until it righted itself, putting the hole above the, thankfully tranquil, water).
@@hanzzel6086 great stuff and very impressive.
@@AaronTheHumanist Modern lifeboats are a rather underappreciated marvel of engineering.
