The anchor cable (chain) plays the primary role in holding a ship at anchor. The mass of the cable and the catenary between the outer end of the cable and the ship offsets the mass of the ship and the dynamic forces acting on it. The anchor serves to hold the furthest outboard end of the cable in place. Direct pull on the anchor only normally occurs when the ship is weighing anchor, and immediately after the anchor is dropped and the ship backs away. At least that's how I learned it during my training in the Royal Navy.
It’s not an anchor wind-lass, it’s a capstan. A windlass has a horizontal main shaft and cable drum (think of a boat trailer which), a capstan has a vertical main shaft and cable drum (as shown in the video). In the case of ship anchors, the drum is a wildcat with proper grooves to engage the anchor chain and draw it in.
WRONG!! One of my friends operated a professional fishing boat until he recently retired. That had a VERTICAL anchor windlass to raise/lower the anchor, & it had written on the drum it was an anchor windlass.
@@christophermarshall5765 Then it was written WRONG!!!!! Capstans and Windlasses basically do the same job but they do have different names depending on whether they operate vertical or horizontally.. But the biggest difference between a capstan and a windlass is that a capstan has a smooth drum and is for moving rope only, while a windlass has a gypsy (teeth) that interlock with the anchor chain. Sometimes there is a drum next to the gypsy on the same shaft that handles rope. It's still a windlass.
That inner piece on each chain link is a British patent/invention from the early 1800s. It stops the chain link from getting caught inside another link, thus fouling the chain.
That inner piece is the stud. Sometimes it is a separate forging that is inserted into the link whilst the link is hot, which then shrinks as it cools to grip the stud tightly. Sometime it is also then welded in for extra security. Some chain lengths have the stud forged into the parent material of the link. The chains made in Boston naval yard were usually like this, as were the chains made from Suel Taylors or Griffin Woodhouse in England, possibly other chain makers as well produced integral stud chain.
@@MyBelch No, no: you're thinking of the Chinese! Seriously, though, almost every new invention in the early 19th century came from either Britain, France, or Germany. If you haven't read about the Industrial Revolution, which happened in the 17th/18th centuries, mainly in Britain, and which created the world we live in, then read some history books. The United States joined the game in mid-century and the Japanese in the late 19th century. All countries have had their periods of technological/cultural fertility at some point in time.
While showing painting of the anchors, you never mentioned why some anchors are painted gold, while others are gray. A gold anchor is awarded to a ship that has a high retention and re-enlistment rate.
Great video, especially the second half about floating wind turbines. There is a small error in the script however that mistakes Megawatts for milliwatts. It's a factor of a billion, but, who's counting...
STOP using artificial voices to read your narration for your videos. It's not "mili-watts": it's MEGA-Watts. WHY would a huge generator only be capable of generating "milli-watts" of power?
I was a line handler once when I was just a nobody E-2 on the Midway, for some reason they didn't have enough people in Deck that day and the old man put out the word all departments send out people, so obviously E-3 and below gets the job. It wasn't to hard but once the rope hit the water, good lord that thing was heavy!
At one point in the design of the Ford class the Navy considered eliminating the STBD anchor as a cost cutting measure. Cost cutting was a high priority in the final design of the Ford Class.
There is a faulty explanation about the anchors, the anchor and the weight of the chains gives that stability. The anchor mostly doesn't engrave itself, it's just laying on the sea bottom. Depending on the sea bottom, if the anchor engrave itself, it would be very dangerous to bringing it back up, because it would pull the ship downwards.
Never been around the 60K lb anchors (and 350 lb links) of a Nimitz class carrier, the biggest I've seen used was the 40K lb anchor and 155 lb links on the USS Essex LHD-2, they are still HUGE though!

I was stationed on the U.S.S . Orian AS18, submarine tender, we were coming back from a cruise from a port in Spain, they medmored the ship, tied the bow on to bouy's , and tied the stern, to the pier, when they were dropping the starboard anchor chain, they lost brackes on the winch system, and the anchor chain went in the ocean, it made a whole lot of niose when it dropped
@@billhuckabee The anchor will dig into the seabed, it is the total weight of anchor and chain that holds the vessel, how heavy is one of those links in the chain.
I believe it is the chain's slack weight that causes the force on the anchor to be horizontal which causes it to dig in. When the anchor is pulled in the force on the anchor becomes vertical as the required slack in the chain is removed.
I wonder how much energy was used to create and deploy this behemoth? What's the payback? How many years to the break-even point? It would be interesting to know this.
The navy could reduce the weight of the anchor and chain by making them out of plastic and cost less by ordering them from China. Donald Trump could order it from his Chinese Friend and make Mexico pay for it.

Wow, i never knew the an anchor could be hydraulic. I thought it would be the winch that was hydraulic, well they say we lean something new every day. 😐
I own one link of a chain like the one on this ship, I bought it off a ship salvage outfit and they brought it over in a container full of salvage they sell from the ship breaking yards in India, UPS delivered it and at 149 pounds it was one pound under UPS's max weight limit per parcel LOL. One link= 149 pounds, imagine the weight of that full chain in the video!
Very interesting, thanks. I am surprised that ship anchors have not evolved with the rest of modern anchors. The old fashion “navy type” anchor or similar seem to still be the norm. Far superior anchors are now available and in use, but not on large ships?? Just slow and expensive to change?
Wrong it's a common belief that it's the anchor that holds a boat or ship but it's not the anchor is there to hold chain, it's the weight of the chain that hold's to boat or ship in place not the anchor
@@billhuckabee If you look at how the chain rests on the bottom when a ship is at anchor you will note there is no strain on the anchor it is the chain holding the ship in place.
I've always wondered how the anchors can reach the ocean floor and dig in when the water is super deep? Surely there's only a certain amount of chain they can carry, so I have to assume there's no way the anchor will reach the floor in mile deep water?
Right. A ship won't anchor it a mile of water... there is no reason to really.... plus, there are 5280 feet in a mile. An aircraft carrier only has about 1000 - 1500 feet of chain per anchor..
Called a Safe Anchor… I ordered a ‘safe’ once while on an Aircraft carrier… I was called out to the pier to receive the ‘safe’… it was a safe anchor like this… another guy ordered three sheets of plywood… we received three truck loads.
If the wind turbines only put out milliwatts you can charge a mobile phone , that's wonderful. But seems an awful lot of work for a few milliwatts of power.
Wait…. You said earlier in the video that big ship anchors can weigh anywhere between 30-50 tons?? But then you said later that the biggest anchor ever made was 36 tons??? So where did the 50 tons anchor claim come from??
9 milliwatts from an of shore wind turbine huh? good enough to charge 2 cell phones at a time.....well worth the hundreds of millions of dollars to build....
IT MUST BE NOTED HOWEVER THAT THE ENERGY USED TO SMELT THE STEEL TO BUILD THE PLATFORMS DID NOT COME FROM RENEWABLE SOURCES: FOSSIL FUELS WERE USED to make the steel. Counterproductive??

A typical anchor on an aircraft carrier can weigh. ,000 30,000 lb and have a chain length of 1,400 ft. They can put that in the ocean. Pretty deep.

Depends on the type of anchor
The weight of the chain is what provides the holding power. It's not the anchor.
The OP has it correct.
When they repaint an aircraft carrier anchor, the paint usually lasts between 5 and 6 years. Thank you.

The c-wise giant was 504 ft. Long and 225 ft wide. It was taken out of service in 2009 and cut up it could carry a lot of barrels of oil too.
This is a correction on the how long the ship was. It was $1,504 ft long.

It is actually the weight of the chain that holds any ships in place.
You're saying just put the chain in the water, no need for the anchor.
@@billhuckabee The anchor will dig into the seabed, it is the total weight of anchor and chain that holds the vessel, how heavy is one of those links in the chain.
@@iansmartel5473 a lot around 150 pounds per link times the length of the chain
I believe it is the chain's slack weight that causes the force on the anchor to be horizontal which causes it to dig in. When the anchor is pulled in the force on the anchor becomes vertical as the required slack in the chain is removed.
Great engineering when they can create big things!
The chain is NOT made to hold the weight of the vessel, only the wind and current loads.
So I assume the people who handle all this mooring gear are required to attend anchor-management classes ?
Mega watts not miliwatts
Do anchors ever get stuck? And if they do, how do they unstuck them?
Just jiggle the chain a bit. 😝😜🤪
