@@thomaslemay8817 I would have expected some sort of cable controlled release mechanism, but I suppose those guys do similarly risky things every week.
Congratulations to the person who calculated the metacentric height of that ship as in my opinion it was very marginal but good enough so once again Hearty congratulations to all concerned with the stability calculations.
6 years late to the party but some things I noticed: 1:18 - Like everyone else has said, obvious crush hazard but they could have also been hit by flying debris as that chock just fucking exploded, wow 2:00 - Rope still connected to the dock snaps and makes 2 guys in the back windows shit themselves. 2:43 - The stand has definitely damaged the underside of the boat, possibly the propeller. Side note: I guess I like dark humour but it's kinda funny that the only black dude is the guy that's actually under the boat, lmao
I live over near Pepper Park in National City (San Diego) Ca. Every few days this awesome boat is here in the Port before dawn, doing its spectacular loading/unloading ritual to/from Hawaii. Marvelous.
Literally amazing how we can build a giant ship on land, and she can glide gently and gracefully over into the water. Kinda odd that we can't engineer a better launch system than having 8 guys physically hammering a teeny pin holding a gajillion tons of ship back, and running for their lives when it starts to move. You probably can't beat that adrenaline rush though either.
That worker was too slow, and in the event, under extreme circumstances, are they to have no choice, but to retreat in between the Propeller, and the Hull of the Ship, this does happen in some countries that eject ships in this manner, but there are MUCH safer alternatives than men backing one another on a pin, the reasoning for so many men in that one area, is simply incase someone slips/falls/trips, as worksite tragedy, is still worksite accident, and no company wants ANY worksite incidents, regardless. Were these men needed to place themselves at risk?, possibly not, again, Circumstances!.
There are two cranes on the other side of the vessel, attached to the tilting "platform" on which the vessel sits. The typical procedure includes knocking out those blocks, THEN-- the cranes lift that side of the platform and let gravity do the work. A lot of water was on/in the vessel and likely contributed to its being off-balance causing the early launch. You can see a lot of water rushing off the vessel during the movement and when the vessel hits the water. In other words, they should've had time to get out from under but the vessel being off-balance started the launch early.
camera person needs some muscle relaxant, or another job. his/ her efforts were shameful, whizzing to the left, whizzing to the right. slow it down dude and focus on the subject.
AND he totally missed the guy stuck under the launcher when the ship started sliding, even though he was right there in the camera frame when it happened.
Thats water from a wet rope that failed in tension. Note the water pour off the top of the vessel as it lists when it hits the water. Speed of sound at sea level is 761mph or 1100 feet per second. From 2:02 to 2:03 the end of the rope maybe covered, 350-400 feet, and thats being liberal with the guess. Don't get me wrong, that shit is moving very fast and would do some Jean Claude Van Damage to anything it hit, but other than its initial instantaneous acceleration (the noise you hear), it wasn't doing what you think it was and what you saw was not the compression cone (mach cone) but just water being shed from a soaked mooring line. The boom you heard was the massive tension load failure. Theres some videos of rope companies load tests which highlight the violence of such failures. Good eye though.
I'm surprised there isn't some sort of health and safety regulation against this or do the workers sign a waver that if they trip and get squished the company won't be held accountable?
@@Dog.soldier1950 That doesn't make sense, because if there is no ballast, then the water would make it top heavy and mean a greater chance of capsizing.
@@Woody615 Ive participated in side launch’s and conventional launch’s-exciting stuff but the launch ways can only take so much weight so lots of fitting out needs to be done before the ship is ready to sail but yes no fuel and no ballast at launch. Launch’s in dry or graveling docks-I was there when the USS Theodore Roosevelt was launched `is a bit different
Well, that's one of the more insane things I've watched on RU-vid lately. How archaic to launch a boat into water.....guys in possible danger and running away from the imminent launch. Are those guys unionized?
@@topgeardel if it was union, there would be 3x as many people and 7x over budget. Having said that - they should fire the manager - completely incompetent and unsafe.
I think I spotted someone in the middle window and the lady below says her son was on the ship when it launched; Can someone with glasses verify if there is a white t-shirt moving around in that middle window because I'm fairly sure I saw someone.
It's easy to explain that. The gross weight of the ship minus the rotational velocity of the propeller divided by the tensile strength of that little yellow wedge is equal to the cross-correlational vector of the full dynamic vintriputal force as computed by the directional tangent of Murphy's Law to the power of infinity raised to the 9th power plus the square root of the inverse value of the Pythagoream's Theorem.
I'll go knock the pin out if u go with me. Ok, I'll go if Rich goes, ok I'll go if Rick goes. Ok, I'll go if Moe goes. So the entire boat builders guild ended up under their creation.
The vessel goes to the outfitting dock where it will be completed, machinery added, ballast taken aboard, fuel etc, etc. She will be just fine when finished.
Probably because they only build the shell of the boat while on land. Literally just enough so that it floats and then they finish installing all the systems and the rest of the build while it's floating. The heavier the ship is, the more dangerous the launch is. Once they finish construction all that extra weight will make it sit quite a bit lower in the water.
1:30 - the black fella at the other side of the steel rigger takes his life into his hands by walking inwards, instead of joining the others. Perhaps he knows something that we can't see.?
This is 2020, almost 2021. Are they still doing the launch that way? You mean to tell me that the shipbuilding industry can't find a safer way to get the boat in the water?
@TheOutLaw Carpenter Whoa, shipmate! I spent a lot of years at sea, so I get your message. And I even laughed! But I hope the intent of your “ef’n” was a result of salty humor vs disgust with someone unfamiliar with launching ships. I think Cats01 is simply unfamiliar and uninformed....and just surprised, is all. And for all the storms at sea I’ve ridden, danger along foreign coastlines, and dangers both seen and unseen in crappy seaports around the world, I always worked hard to the best of my ability to mitigate risk to my crew and my ship. Even so, I was surprised....and maybe as was Cats01....that launching required two guys with sledges “banging away” at that pin” from under the hull.....and once loosened, they and the observers having to sprint to safety. Still, your salty humorous response happily brought back memories of my favorite Bos’n Warrants and CPOs! So, thanks, amigo!
@@captaincoyote1792 Hmm, but there must be a better way (something hydraulic perhaps) than a couple of blokes with sledge hammers bashing a chock away and why so many hanging about watching the hammers lads going at it as well. At least on a stern in slipway the hulls are built on a set of runners with plenty of room underneath in case of an oh dear moment for the sledge hammer gang.
TheOutLaw Carpenter You are the real idiot. Because of your stupid rude behavior. Cats01 is absolutely right. To bang with hammers, and then run like scared kid steeling apples from the angry old neighbor, is not a professional way of release a 1000 ton ship.
@@figgeberglund4145 Well you can launch them how ever you like at YOUR ship yard. But I doubt you have much of a problem launching a rubber duckie in your bathtub....
ooooo Wow it’s amazing to see a rope that big crack like that, what is the stuff that comes off the end when it cracks? Is it just like water or something?
Boats are launched when their hulls are complete and engines are in place. Much of the superstructure and internal fittings and equipment is not yet installed. As a result, at launch they ride high in the water. Once completed, more than half of the exposed red portion of the lower hull will be underwater- and ALL of it submerged when she is fully loaded. But even then... Boats All stick higher u out of the water than they do down into the water. Being somewhat visually top heavy is not a problem because the portion of the hull under water contains ballast to lower the center of gravity, and the hull is designed so the center of buoyancy is below the center of gravity...As the boat tips, the center of gravity remains fixed- but the center of buoyancy shifts- ( the tipping hull displaces water in a different shape- the century of buoyancy is the center of gravity of the volume of water displaced. Ergo- if the port side of the hull is lower and the starboard side lifted partly out of the water, the center of mass of water displaced moves to the port side, and so the force of buoyancy is pushing upwards on the port side of the C of G... lifting the low side of the ship until the C of B is directly under the C of G again..
