You can tell this ship uses direct drive diesel propulsion, by the way the propeller springs back (even back and forth) a bit after it stops, due to compression in the cylinders.
Oh my Goodness, these things are really freaky. Just imagine diving and suddenly seeing or hearing one of these props close to you... That is really scary!
Well In britannic disaster that unfortunately happened, a German U-boat stroke a torpedo at Britannic and when it slowly sank, the propellers came up onto the water and caused a stream which leaded the life boats there and so... 1,600 people survived and all 30 who died where crushed by the propellers... There is a movie of Britannic and the scene of that propeller thing...
Imagine how it was when the Titanic's sister ship the Britannic was sinking. The Britannic struck a mine during WW1 and started sinking fast. She was almost identical to Titanic and was being used a hospital ship. The captain restarted the engines to try to ground the ship before it sank. Her propellers where as big as Titanic's, 23 feet six inches or 7.163 meters across. They were launching the lifeboats while the ship was going down. The propellers came out of the water just like you see here. The huge propellers sucked two lifeboats into them and chopped the boats and everyone into pieces. The captain stopped the engines right before the third lifeboat was pulled in.
I remember seeing one when I was a child and haven't seen on half way out of the water like that in years, one thing I noticed when they engage the propeller how quickly the boat move forward or backwards cool video thank you so much for sharing
Agree absolutely; I'm not sure it is just the propeller though, I think I fear the whole thing for some less rational reason. Glad I'm not the only one though! :-)
Right with you there. Ships and ports fascinate me, but I have a morbid fear of falling in the water alongside something like that and getting mashed, or squashed between ship and quay. Just looking at it makes me feel queasy (what kind of man am I you ask...)
@2fast4u510 yes but the balast tank is not filled with water so when it is full the boat go's down in the water and it isent called just a thing its called a prop (propela)
@12GAshotgunnersrain You and me both. I have been afraid of boat props since I was a kid and my uncle kept his boat in the garage with the engine facing the dryer. I was always terrified it would suddenly come on. LOL
They move a lot of water I mean really almost twice water when they are spinning backwards... I always wonder if it is a flaw on the propellers design, I mean every single big ship has it, that propellers look concave in the wrong direction, I don't know why or find a reason for that and this video proves that, backwards spinning moves way a lot of water more than regular forward direction
What kind of lines were used? When I was in the navy we used to use dyneema lines to get the last kts off when mooring, on an LPD, Insanely strong lines
I don't know about this but im from around the great lakes and they take on ballast(water to keep the prop in water lol) before even giving engine orders.
I can greatly understand some of these people's fears. For example, when HMHS Brittanic was sinking, some of the people who managed to get off the vessel and into the water ended up getting sucked into her propellers. What a way to go...
Hi, Im a film student working on a short documentary on ship passing through the channel, I saw your video on the ship propeller and I was wondering if I could use it in my film? Its non commercial film used for school. Let me know! I would of course credit your work.
Of course, that goes without saying. It stands to all logic and reason that, When for example AP Møller puts x millions into building a containership, they design a wrong size prop. What kind of mindset makes you even post something like what you did? The prop is built to very exact specs for the vessel. Pitch, rake, camber, cup, number of blades, diameter ect., is spot on for target speed and prop slip.
Some of those big propellers can weigh 50 tons, even at just 5 rpm a strike by a blade would probably crush all the bones in your body besides what happens to your torso. I doubt at the speed it was rotating probably around 20- 30 rpm there would be much left. I think on the ocean the top rotation speed probably would never exceed 125 rpm

The info you never know you so desperately needed.
Those lifeboats were launched by people without permission
Yes I know
The ship didn't stuck a mine, it was hit by a torpedo
@@danielgames1027 that was just in the movie
For those who are scared of ship propellers, it’s a phobia called submechiphobia. Hope that helped.
i scared with this
Actually, it’s called common sense

Dumbass
Submechanophobia but yeah...
Stupidest phobia ever
He spin...
He push...
But most importantly:
He will turn you into a slush...

I’m not scared, I actually think it’s amazing

Actually I noticed that too and I was using the letters on the LNG tanker in the back ground to gauge how far forward and astern it was moving
@@vaughnppeters6451 same I used the tanker in the background to judge how far it moved
I think its cavitating a little :)
If this sort of thing freaks you out watch the boat chase scene in Indiana Jones and the Last Crusade.
Barb Wire that freaked me out alot
Happened in real life when the Britannic sunk. Sucked in 2 lifeboats and chopped everything and everyone up.
This is what nightmares are made of.
Nice to see something that is usually hidden far underneath the water. Looks like about 30 rpm, so maybe that's half ahead/astern?
Poly Hexamethyl I think full ahead is usually 100to 120 so this is probably dead slow ahead
How fast is 30rpms? I know it's rounds per minute. But like how far could a ship go going 30rpms? Like 10nautical miles? Or..?
Agree absolutely; I'm not sure it is just the propeller though, I think I fear the whole thing for some less rational reason. Glad I'm not the only one though! :-)
Did anyone else notice the LNG carrier in the back.
Super Trini Gamer I did!👍
NIce!
Who wouldn't
That thing right there is probably one of my biggest fears!
Some ships carry either one enormous propeller or two at the stern in order to move the ship forward. Depends on how big the ship is.
Ships like Titanic had three propellers, and Lusitania had four.
This could have been 1 minute long and would still have been just as complete and effective.
An underwater shot of this would be awesome.
scary as hell
AlphaDeluxe1 what's scary about it?..
AlphaDeluxe1 Yeah it kind of is!
why does everybody think its scary?? I love propellers looking out of the water!!
AlphaDelux
fghjj fgh yes me too its rare
Cool. I want one.
I'm assuming this ship was empty so that's why it's out of the water like that? Seen this a coupme times now and still in awe everytime
Yes, when the ship is loaded the entire propeller is underwater and so is that horizontal overhang above it.
@@trainzguy2472 nah, this is one of them efficient surface drives. When the ship is on plane only half of the prop is in the water. 😂
Right with you there. Ships and ports fascinate me, but I have a morbid fear of falling in the water alongside something like that and getting mashed, or squashed between ship and quay. Just looking at it makes me feel queasy (what kind of man am I you ask...)
Why am I finding it so satisfying?
@2fast4u510 yes but the balast tank is not filled with water so when it is full the boat go's down in the water and it isent called just a thing its called a prop (propela)
Just did a re-check. Nope, 9,6 meters.
Still big as hell, and perfect nightmare fuel. "dark water,,,, chop, chop, chop"
ship propellers are interesting and awsome to
The prop is halfway out of the water. There's bound to be some sideways forces when it turns half in, half out.
@12GAshotgunnersrain You and me both. I have been afraid of boat props since I was a kid and my uncle kept his boat in the garage with the engine facing the dryer. I was always terrified it would suddenly come on. LOL
How exactly does the props come to be above the water
No cargo and no water in the ballast tanks.
"Oh no! Help me..." chop chop chop chop
That was a rope stretcher as you see the N try to disappear and the L suddenly appear 😉👍👍🇺🇸
recommended after 11 years 😊😊😊
That's one huge prop !!!!! 😲
Are the props on big ships like this supossed to sit 1/2 way out of the water? Im 12 but i love watching these. So yeah are they supossed to?
I know what you mean man. I hate being in the water next big boats, I always feel like i might get sucked under the thing
What vessel is this ? Seems to be a Maersk vessel because it looks like their color blue which is barely visible.
They move a lot of water I mean really almost twice water when they are spinning backwards... I always wonder if it is a flaw on the propellers design, I mean every single big ship has it, that propellers look concave in the wrong direction, I don't know why or find a reason for that and this video proves that, backwards spinning moves way a lot of water more than regular forward direction
That is one thicc boat
Touch it
A hélice não deveria ficar toda dentro d'água?
Thats one of those top secret non cavitation props like on the ‘titanic?
No way I could be one of those people who have to clean those things under water.
Jody propellers aren’t cleaned underwater, when a ship is in a drydock is when propellers are cleaned.
How deep must the water be for a ship that size to safely float in a harbor? Just curious!
What are they testing for in this situation? I'd guess to make sure everything works before the next trip?
What kind of lines were used? When I was in the navy we used to use dyneema lines to get the last kts off when mooring, on an LPD, Insanely strong lines
I love propellar. I wish i could touch it while spinning
Submechanophobia just kicked-in yo.
Yeah what he said
why do these big ships have their prop half way out of the water?
are those things susposed to be under the water??
Why are the props out of the water?
Why is the prop partly out of the water?
I don't know about this but im from around the great lakes and they take on ballast(water to keep the prop in water lol) before even giving engine orders.
Is this the "wash" or "rinse" cycle?
Ronald Robertson HAHAHHAHAHAHAHA
mine too! I have a phobia of ship propellers!
Now where’s Indiana Jones and his speed boat
👁👄👁
Imagine seeing that thing while scuba diving and starts rotating. I'll be like a basilisk lizard if I saw that shit!
Because this ship is in ballast,no cargo ! :)
It is unloaded. If it was carrying cargo and fuel, the entire hull will drop down about 40 ft.
How is this terrifying... its litterally a boat propeller
Awesome
Should put this prop on my dinghy... lol
esmi000 super speed and home made sub
im not afraid of em just wont go close to em while they r moving or at all
How much energy for give power boat speed to as like ship??
Oh ok. Ive always wondered why these cargo ships sit with the prop 1/2 way out of the water.
Anyone happen to know the approximate diameter of this prop? My guess is about 10 feet....
Seriously, why are so many people creeped out by this?
Submechanophobia. Look it up.
Try living in a desert your whole life and also have this phobia it hits different.
this is a maersk ship?
Is this technically an inboard
imagine getting thrown in there off a little boat and as ur falling, ur leg gets caught under the prop first as it drags you in and minces you up
It's not some old steam ship with primitive gears.
I can greatly understand some of these people's fears. For example, when HMHS Brittanic was sinking, some of the people who managed to get off the vessel and into the water ended up getting sucked into her propellers. What a way to go...
You fall into that monster and you don't get a second chance!!
Imagine being underwater with that thing......

creepy as heck
Thought I was the only one that felt that! I think it's being under something that's meant to float :L

jack imagine getting sucked in one!
ikr

I believe the rocord was set by the Emma Maersk with a 9.6 m. prop. But yeah the guy commenting on it being too small?! Eeh,,,, no.
why is the propeller sticking out of the water?
The ship is empty ad they did not fill anything in ballast tanks
Anyone know how many blades on the propeller?
Never gonna get anywhere unless they untie it!
And still...
what ship?
wow that's big
CIA hahaha it's a bit of banter
Anxiety level increases....

I doubt at the speed it was rotating probably around 20- 30 rpm there would be much left. I think on the ocean the top rotation speed probably would never exceed 125 rpm
Why do they do this? I mean test the engine?
DING DING engine room full speed ahead.
that would be fun to swim around
that has to be a 15-20 ton prop
Closer to 35-40 tons, if I remember.

33 feet, I think.
Nope, 50-70

Neat, Thanks for posting
Turns out it's a 3cyl Geo on a treadmill ! Who knew ?
wouldnt it be more effective to have the rotor fully submerged/
it usually is
+Parallax may be the ship is empty now....when its loaded the prop will completely under water
Basically it's a marine food blender
I always thought that was under the water
