The oil spill in Huntigton Beach last year was caused by a ship anchoring in a prohibited location- the pipe was displaced a considerable distance before it failed.
Pulling all EIGHT anchors from the semi submersible oil rig on moving day is one hell of a party along with the rollback anchor "boat" that assists with their winches and our crane aboard the rig. The more anchors are pulled, the less steady the rig/crane are when crawling up onto the anchors once on the boat deck to pull the many pound shackles while knowing what swells will make the anchor taught on the line with the movement of the boat AND the crane lines from WAAAAAYYY up there is a dance for sure
It is possible to untangle the the anchor fouled onto a cable with wmall ships, up to 25; 30 meters). I did it a couple of times with my 30footer sailboat.Needless to say I wasn't proud and kept a low profile as cables and these types of obstructions are well marked on charts with dedicated signal onshore : bacically it was pure negligence.
The weight of the chain and/or anchor plays a very small role... Think of it VS the weight of the ship! Chain weight and mostly length is so the anchor pull is parallel to the surface movement, letting the anchor work. The length of chain also plays a big role through mechanical resistance of each link, preventing motion/waves to get all the way to the anchor.
First statements are completely wrong. It's the anchor and scope, scope, scope. Literally the length of the anchor chain or rope tied to the anchor. (In sufficient wind, the chain become bar-tight, just like a rope would.)
One of the things that Naval ships were expected to be proficient at was a "precision anchorage. We were graded by how close to the given drop point we could place the anchor.
No the angle of the chain helps set the anchor and help keep it holding. The 5-7 times in length is called the anchor's "scope". Yes if it weren't for the chain the anchor wouldn't hold, but without the anchor the chain will not hold the ship on it's own. The chain doesn't really provide holding power itself, it only facilitates it though geometry.
Wrong - the length of chain laid out is to keep the force on the anchor parallel to the seabed. If you try to anchor with a rope or a short chain, when the ship pulls on the anchor, it pulls in an upward direction and the anchor comes out. The heavy chain lays along the bottom and changes that upward force into a horizontal force and the anchor does not pull out. This is why ships put out more chain when the wind blows harder.
Sail driven ships, used to move the ship by putting the anchor on a long boat. Row the long boats with the anchor out in front of the ship. At a point about 100 yards in front the long boat crew would drop the anchor. After dropping the anchor 100 yards in front of the ship. Once the anchor hits the bottom, then the ship crew pulls into the ship. The process of pulling the ship forward. Once the ship moves over the anchor, the anchor is placed back in the long boat, and the process starts over.
Do not pull the ship by taking the anchor chain in. You have to move the ship by engine slowly towards the direction of the anchor while pulling it in.
Wrong, the weight of the chain helps avoid chafe on an anchor line against the bottom, the weight also acts as a spring in waves when the boat is forced back by a wave, and finally, the weight of the chain can increase the horizontal pull on the anchor and increase the likelihood the flukes on the anchor dig into the soft bottom. It does not however cause any resistance.
a chinese ship deliberately destroyed a pipelines and communication cables on the sea floor between Finland and Estonia, allegedly. Given the fact it circled on the coordinates for a longer time, makes it highly likely it was an deliberate act, imo.
I have a anchor and then only maybe 1 meter of chain on my boat, as long as you exaggerate with anchor size and then have as much rope as you can you should be fine.
A well anchored small boat even using a rope will always have a good few metres of chain at the anchor end. Just using rope will be fairly useless and the rope will get damaged quickly and not be very effective at holding in any wind or current.
Coral reefs are close to the surface of the sea, so you can't sail over a coral reef with a large, ocean-going vessel, or at least if you did you would do a _huge_ amount of damage. .... One bulk carrier, Chinese IIRC, steered across the Great Barrier Reef off Australia's east coast about a decade ago, tearing a huge gash across the reef.
Chains are actually to pull the anchor down into the right angle to allow it to dig in. The "friction" claim in this video? Hmmm not too sure about that at all.
@@cvanscho the anchor is to help pull out the chain correctly out and make sure it stay correctly on the sea bottom. they do that while the ship is backing up. the weight and friction of the chain, is holding the ship in place, it also act as an spring. one thing they do when drooping the anchor, is that they first droop the anchor to the sea bottom with some slack on the chain. Then they stop drooping chain, so they can pull on the anchor, so it flips over and dig in, to hold the chain in place, first then they droop rest of the chain, while backing up. for example, an 60 ton anchor, as on US aircraft carriers, can't hold the 100.000 ton aircraft carrier in place. A single link on a anchor chain for an aircraft carrier can weight up to 360 lb (164kg), and you have around 1500-1800 foot of chain
No. No it's not. The primary force is the giant prongs stabbing the bottom. I've heard this before and it's bs. The weight helps the chain pull horizontal and not vertically.
The anchor digs into the seabed and is moved around as the ship drifts on the surface, dragging the chain and causing 'broomstick-like' abrasions, killing off marine species and releasing carbon stores from the sediment. This has far-reaching implications for already stressed ecosystems and carbon cycling.
This same thing happened to His Royal Highness thenthen Prince of Whales when he was in command of a ship in the Royal Navy. They lost one of the most expensive parts of the ship. That tungeston chain.
my neighbor's wife's Ass is just like this Anchor sits on her husband then he can't move seems that he was not even breathing last time when she gets angry to him 😅
Whoever is saying this is completely incorrect . Anchors hold modern ships in place with their weight but not by getting to the sea floor but simply floating.
Is their any responsibility of the criminals using the guns against one another because of their tribal tendencies. Civilized people don't hate others just because they live in another part of town.
The largest ships have more than one anchor. For instance an aircraft carrier has 2 weighing 60 to tons each.
Every Naval ship I served on had 2 anchors except the submarine.
I work on semi submersible heavylift.
This type of vessel have 3 anchors.
Reason for 2 ore more anchors is mostly to have at least 1 spare!

Exactly 💯%. Try to "anchor" only with a chain without an anchor. Good luck with it. The whole story is a big nonsense.
This makes more sense.
Scope is everything

You can afford that😅

It is not the friction on the sea bed. It is the forces required to lift the chain as tension is appiled.
Dropping anchor for almost 25 years! Done with it. God bless all seafarers🙏
Still doing it. Couple of years to go.
Interesting. Thanks!
7 times the water depth is usually a good "scope" of chain
Do not pull the ship by taking the anchor chain in. You have to move the ship by engine slowly towards the direction of the anchor while pulling it in.
Was looking for this comment. Pulling the ship with windlass is a stupid stupid thing to do.
Went sailing Greek island. We witnessed 2-3 yachts anchors crossed.........much fun ensured.
Very good, you said "lying" and not "laying." You got the job@

Great care is taken to not drop anchor where there's underwater cables.
Kamchatka: And I took that challenge seriously.
I wonder how many anchors are in our oceans right now that had been cut? I bet theres tons
How did they cut the chain?
Lazer cut
They have giant scissors. Takes 84 people to operate them.
@@justlucky8254😂😂
Perhaps a hacksaw.
🤔 torch 😏
It's an exhilarating experience. The potential for severe harm to the anchor detail is there.
Interested in this technique. I have a 175` Yachats, 6 stateroom. I need a good idea!
Rock can be a great hold of it's larger than your boat and you can't get the anchor loose of it.
I was just thinking theres no way just an anchor is enough to hold back a ship the other day, lol
You’ve used an illustration of an oil tanker while stating “the anchor does help” which is going to mislead a lot of landlubbers.
Now here is a situation where 'payed' would be the grammatically correct term, and yet the video STILL gets it wrong.
“Great deal of work”
How do sea anchors work?

NewNew Polar Bear must not have gotten the memo about where not to drop anchor. /I currently believe it was intentional with plausible deniability.
5 to 7 times in bad weather maybe. 3 times the water depth was plenty when I anchored.
we are talking about big ship, not a dingy!
I was chief officer on large vessels travelling everywhere in the world.
What about small boats that use ropes. Just wondering about the applied principle.
Not going to work very well. Even a bit of chain helps a lot (keeps anchor at the right angle to dig in).

What if that anchor engaged those pipe lines or cable lines, that would be an heluva damaged!!!
how much of the sea bed do these anchors destroy in a year i wonder
I commercially fish for salmon, we pulled up a submerged tree once
I wonder how much torque?? 🤔 does anyone know?
What about the bitter end chain link that can be released if all else fails
You don’t ever want to do that except in a shipyard.
The function of the chain is to work as a spring
Interesting
I had thought about that
Speaking as a sailor who lives 100% on his boat, there is so much wrong information in this video I don’t know where to start 😅
What happens when the anchor is not as long as the ocean floor is deep?
The same captain was addicted to horse and dad didnt know because of sealed orders in those days

Halfway decent explanation.
