When I was a kid I remember being told that each link of the Queen Mary's anchor chain weighed one hundred-weight. That being so, then twenty links to the ton. I don't know if anchor chain metallurgy has changed much since the 30s, but I suspect that modern chains are are similar as the chain itself lying along the seabed is what usually does most of the "holding".
@@notallowedtobehonest2539 I know that the UK uses "stones", otherwise I would be completely lost with your comment. Even assuming that you are trolling me with "stones" to explain "100weight". Crazy units. Thanks for the information.
Deadly complacency walking over to the windlass and tilting his head towards the chain as it thunders past with the power of a run away locomotive. Whatever went bad wrong would spread body pieces every where. He did look old so maybe his time is near.
Got something to say about old folk? Because in my experience, they generally know a shed-load more about what they're doing than idiotic little keyboard warriors, commenting on things they know nothing about, but believe they're an expert because they saw a "Navy TH-cam" video like you. :)
Oli Doran hey oil I'm 78 years old learned much of what I know about playing it safe from old guys lke me. This old guy just wanted to get on camera. You don't see any of the other men wandering near this monster.
that is exactly how you test the windlass, they then put it gear and are testing engine.Normally you would let it free wheel till you have the depth required which is done by counting the number of shackles that are sighted as the cable goes out. Note every now and then there is a red link with white paint either side, thats the shackle.... as the cable goes out each side of the red shackle has white painted chain links, 1 shackle is one white link painted either side of the shackle, the next is two links painted white either side of the shackle and so on like that.
Surprised this isn’t a geared braking system. Just a drum style with a 1/1. I would think there would be a planetary drive to the braking drum but hey if it works it works.
@@david667766 right but this isn’t exactly an emergency. Big trucks have j brakes. Just seen these fail before I wonder if any of them are geared somehow
@@david667766 I looked turns out they pretty much all have this one big drum brake and some kind of manual handle or wheel for it. It is pretty simple I just seen them fail. Probably pretty rare and had no brake padding left in those ones.
I’m surprised that they don’t have what is on the main drum of large drilling rigs and some very large trucks. A hydro retarder. Basically a torque converter in reverse. One turbine on the drum shaft trying to turn another turbine that is mounted stationary. The amount of restriction is controlled by the angle of the turbine blades and the clearance between the turbines. Some use oil and require heat exchangers and some use water and as they warm circulatory valves open allowing hot water out and cool water in as needed.
The brake works better with higher revolutions. It only fails when the realeased chain length is too long. That was a free fall release. Afterwards the chain is falling slowly with motor braking.
Seems like a great idea to test the ability of a wearable item, which wears it. What if it passes the test but fails on the very next instance whereas you could have used it a couple more times without testing it?
If there's something i have high respect on a ship it's its anchor, i wouldnt work there even if they'd gave me millions, that thing could make a person into pieces.
First of all, you cannot anchor in deep water. The crew already knows how deep the water is and how much chain they have. A large ship typically needs at least 5 times as much chain as the depth of the water in order to properly set the anchor. If they don't have it, they won't even try.
If sea bed is too deep, there is no need to anchor. Its not like the ship will ground or something. Ships are usually anchored in shallow waters where there is a chance of the ship being dragged by the wind towards ground. In deep sea if ships have to stop for some engine repair job they drift freely.
This is a ships anchor chain. They are testing the braking system of the anchor chain. Ships anchors are lowered by gravity and there is only one drum brake to restrict its motion. By regulation the drum brake should have braking power of 40% of the cable's failing load. The inspectors are here to tst the braking efficiency. Whether the brake slips or not.
The "governor" is called a "brake." That's the only thing that can stop the chain. When the brake fails, it's good bye anchor. Well, an attempt will usually be made to recover the anchor as it's usually in fairly shallow water.
On very large ships with very heavy anchors arrangements are provided for controlled lowering in addition to gravity lowering. In such ships the electric or hydraulic motor that picks up the anchor can also be run in reverse direction under controlled speed to lower the anchor. But i agree there should have been some kind of centrifugal braking arrangement as well to control the speed of lowering on all boats.
Jaj! Muy buenos los frenos al principio. Pero yo quiero verte frenando el ancla cuando ya vienes largando más de 30 metros de cadena, y la cosa esa cae a velocidad de estampida.
Yes correct. On large ships the anchor can be lowered by 2 methods. By using the same motor ( electric and hydraulic ) that is used to lift up the anchor and is known as the walk back method. The qnchor is lowere by driving the motor at a fixed speed. And the other method is to let it go down freely under gravity also known as the let go method.
Once you see the video of a run away anchor drop from a huge naval ship, you will realize the complete stupidity of the old crew member sticking his head near that thundering anchor chain and doing what??? After this video I now understand how ships at sea run into each other or hit reefs or rocks or piers. The old guys are always in charge come hell or high water.

What is "one hundred-weight"? Is that like "one hundred-lenght" or an actual unit?
@@leocurious9919stones used to weigh 12.5 and 8 of them would be a 100weight. Now stones weigh 14 lbs and it means 112 lbs but the name is the same.

its a normal day for us while anchoring

What if the water is too deep, the anchor will not reach the sea bed. What happens then ??

Can someone who understands the technicalities of this please explain. I'd love to learn about this..
Brother they are testing the anchor of a ship; whether the ship gear,like brake etc. will hold the anchor and its chain .

By regulation the drum brake should have braking power of 40% of the cable's failing load. The inspectors are here to tst the braking efficiency. Whether the brake slips or not.

Why don't these windlass's have some sort of governor on them to prevent runaways?
The "governor" is called a "brake." That's the only thing that can stop the chain. When the brake fails, it's good bye anchor. Well, an attempt will usually be made to recover the anchor as it's usually in fairly shallow water.
On very large ships with very heavy anchors arrangements are provided for controlled lowering in addition to gravity lowering. In such ships the electric or hydraulic motor that picks up the anchor can also be run in reverse direction under controlled speed to lower the anchor.

What happened with the one that completely went off the reel in that other video? Brake failed?
I wish the camera would have panned to what ever that guy in the green hat was pointing at.
1 Shot is ninety feet of Anchor, he is counting Shots. Each link is 136 lbs.
@@scottwins2 was it the red and white painted chain?
@@ShiratoriIsOffline yea the red and white painted are called shackles which indicate how many shackles are dropped. 1 shackles is 27.5 m.

Those hard hats are completely pointless. If that thing goes no way a quarter of an plastic will save your head.
So wear no PPE at all? Teach us more please.
If some piece of the breaking chain flys off, it might just be the thing that saves your life.
brake model is obsolete shit who prone to block, whole mechanism cry for redesign
a shame you dont show the entire video of this test. waste of 2.47 min of my life
How to kill a brake during test is exactly this. Stupid proofer!
