Have you ever wondered how some ships are able to break through thick ice and others are not?
In this video, I will show you how icebreakers use their weight to break through sheet of ice and make paths for other vessels to be able to pass though.

" Oi, mate... "
haha! good one
Yeah that is what happens after breaking the ice......
Hi, care to see my bow?
Once the ice is broken, a relation-ship can pass through.
and what if you prefer a couple of subs instead?

Oooooooooohhhhhhhhhhhhhhh!!!!!!!!!!
Best comment lol

What's wrong with this guy?!!?
No stretching to ten minutes, no "smashing"the like button, no begging to subscribe..
I feel lost now!!!
True...
Also no actual information
By this short video he was just clarifying the fact that bulbous bow of ships (on which he had previously done a video and many thought it was for breaking ice) are not meant for ice-breaking.
@@jordanbarrett7754 what do you mean no information??? he showed us how it works, and told us how it works
@@jordanbarrett7754 I already knew how they worked so maybe I'm a bit biased but what questions do you still have about how the ship breaks ice? Hearing stats about engine power or how thick the hull is doesnt explain how it breaks ice. So, as far as the title is concerned, everything seemed explained to me.
This video is to the point , but id like to know more, for eg how thick the iron is on an ice breaker ,designs , engine horse power ect , stuff like that ..
The swedish icebreakes has a 36mm hull and has twin proppellers in the front an the back so they can break the ice better and they have 25000 hp. Google icebreaker atle for more info
Russian icebreakers are the only nuclear powered civilian ships
@@wiggonilsson7258
Nice pi.
The question was, how do Icebreakers break ice, not how they are build and look.
@A. Wellknownmyth
Apple pie ?
When I was a kid, I thought they had mechanical arms that would break the ice.
Austin Powers - Judo chop!"
jayive34 too much outlaw star thier pal
this aint the 1860s bub
There is a cartoon explaining this, yes an arm comes out of a hole in the bow with a LARGE ICE PICK and starts picking. Just like at home.
I just thought they used powerful engines and a sharp reinforced edge.
Wait... so they don't use giant underwater Chainsaws?
only after reading this comment do i feel disappointed.
they use that for bays
Im disappointed now
Nah, they upgraded to forward mounted flamethrowers to just melt everything.
T h e G l o b a l W a r m i n g A n d F l o o d i n g ! ! !
This video is way too simple, I wish there was more information
Atleast strait to the point bro
I mean I cebreaker operate on a really easy concept: "Spoon" shaped bow + powerful emgines. You ride on top tje oce and breaks it with your weight.
My thought exactly
I agree, there is actually alot more to an ice breaker than this. There should for example have been atleast a mention of ice breakers that use their propellers to break ice that is to thick to break the conventional way
Me too
1:37 “Ice fields are vast areas covered in ice.”
Hmmm yes. The floor here is made out of floor.
Draggy654 Wait are you serious? I had no idea! Damn, this is such a world shattering revelation you’ve brought to my attention. Thank you for your stunning display of intellect.

Honestly, I'm betting this channel is gonna blow up in a year or so. Don't give up till then and up the good work!
Thanks SupaL33tKillar. All the while the content is enjoyed, I count that as a success
And it's happened! In less than a year even. The almighty CZcams algorithm broke the ice to a lot of viewers and the channel's ice strengthened hull navigated casually behind it.
Youre a prophet
I was like hell no it's already big.. "10 months ago" aight mate
@@CasualNavigation well i was never interested in boats or something similar, but your videos kept comming to home page, and i was like "this might be interesting", and it was, so even i didn't need those informations, i kept watching you and soon after that i gave you sub, keep doing good work!
The Coast Guard ice breakers are super cool and go to some awesome places. They're prime picks for any Coastie.
The scenery they get to visit is stunning
The Casual Navigator It is. Unfortunately due to their age, they are in Dry Dock a lot. I have a friend from boot camp who's on the polar star and in their time there, they've been in dry dock more than they've been in the water.
Austin Hurley my W4 was a nonrate on the Polar Star
I always thought that ice breaker acutely break the ice, like cleave through it with a sharp bow or something. This video was enlightening, thank you.
P.s. Maybe they should catagories them as "Ice Crushers".
They don't really crush the ice. They break it and push it down.
Well they do kinda be cutting it with their bow, just takes a lot of crushing weight to cut through the ice.
That and I suppose the bow probably isn’t kept all that sharp just cuz it would be so impractical to sharpen
The Finnish translation for ice breakers would be jäänmurtaja. That means actually ice crusher.
That makes sense.
Great video! I was on the icebreaker, the USCGC Northwind, back in the late 1970's. Broke ice in the Great Lakes one cold ass Winter. I really liked watching from her bow as she broke through the ice. The ice would split open and shoot up out to the side on top of the ice clearing a path ahead. Flat ice was easy to break through, but the "Windroves", or ice mountain ridges, could stop us cold. The ship would have to get unstuck and ram it again. And sometimes again and again.
Well, the algorithm persisted I learn how Ice breaker works so here we go
And to think I had to search for it myself! All the while some here are evidently favorites and catered to with this magnificent content. 😂😂🤪
The ending was so sudden... no misc info, just; “it has a fancy bow”. Splendid
Check Comercial icebraker "Sampo" in Kemi, Finland, where one can experience all the joys of icebraking, like swim in frozen sea. "How thick ica can an icebroker brake?" We thought like 3-4 metres, actually some 20 metres (sic!)!
Two great videos, thanks. I love short videos that just explain a single topic concisely.
Thanks Simon. That was the aim for this one, glad you enjoyed it
I got a tour of the Healy a few weeks ago! The crew was pretty cool and very helpful in answering questions.
She does look like a nice ship to be on
@@CasualNavigation she wasn’t too bad. I spent 3 years on Healy (and took some of the footage/stills from this video. Lemme know if you have any questions.
The uscgc healy is a medium endurance ice breaker, it has what's called an "ice knife" that is uses to chip away at the ice. It doesn't ride up on the ice like heavy endurance ice breakers such as the polar star does.
"So, you come here often?" - icebreaker
They operate by finding common ground between the two parties, so that there’s an immediate sense of bonding. It doesn’t always have to be a “positive” subject; so long as it’s a subject that both parties can relate to, that should suffice.
I was on WAGB-10 Polar Star and it was an awesome experience.
I always thought it was just ships with reinforced hulls that ice can't break. Never realize there was a technique to it.
Ice strengthened ships can have bulbous bows. I worked on bulk carriers and car carriers which were designed to break through first year ice. I took the bulk carriers through ice in the St Lawrence seaway and the car carriers through Ice in Finland. You aim for cracks in the ice using the radar. These ships had Controllable pitch propellers and a knife behind the rudder for piercing the ice when going astern. Being able to keep the propeller turning and just change the pitch made them easier for going ahead and astern to ram into ice.
The USCG Polar Star employs 3 giant electric motors to propel the ship during icebreaking to prevent mechanical damage if the propeller strikes ice. Also the ship carries over a million gallons of fuel that assists in added weight for crushing up to a maximum of 20 feet ice thickness! I had the pleasure of working aboard this beast of a ship.
oh I love this straighforward right to the point video like this one, you are just the best
I love the short, concise content. CZcams used to be full of videos like this that explained concepts simply before they started promoting videos for length.
Keep on fighting the good fight!
yes
Hello, Casual Navigation.
Your video about the topic icebreaks truly made the understanding of how the icebreaker can work going threw the frozen state of water.
From the explaining to simply showing really makes my mind tingle with joy, of happiness that we can live in a world where common knowledge is for everyone, unlike it was once not so long ago.
Sincerely yours, Alfred.
Great info. I did wondered about this ice breaker. I did see the other video of the bow difference too. Good job
Wow! The way it’s done completely surprised me. Thank you for creating this video.
Beautiful clear explanation!!!
Thank you for good video
The US Coast Guard Bay Class icebreaking tugs have a bubbler system that injects air to the keel making the hull slippery to the ice. This allows the tug to break ice thicker than it would without the system installed.
Now that's more like it . A real info .
It’s 4 am and really care about ships , but here I am , this was fascinating 😊
I was on the Healy during that Renda trip.
You're thinking of the heavy icebreakers, they go up and down like your picture.
The Healy is a medium, it just pushes through.
Thanks for the clarification sminthian
I actually helped build the Healy, I was in the shop that cut the hull plates and structural steel. I hope we built you a good ship.
Still all (not "medieval") icebreakers rely on forcing ice to bend under ship and its weight.
"Climbing" on top of ice just doesn't happen until ice is thick enough to resist initial contact.
Or there's pressure ridge... down to bottom and needing use of that "ramming speed" from movies:

Straight to the point. Thank u.
Precise and concise. Thank you for clarifying the ice-breaking process.

My mum and dad explained this concept to me when I was about six years old! They weren’t sailors but knew about it when I asked the question. United States ships visited Wellington a lot on their way to the Antartica including ice breakers
That was very informative, cured my curiosity, nice short and sweet thank you.
Thanks Craig
Developers should look into changing CZcams's algorithm. Why CZcams didn't recommend this channel to me before. Subscribing right now
The thing is that it will do anything to increase watch time
so shorter videos get recommended because people probably will watch all of it and to get better the algorithm train itself by recommended random videos and see the viewer reaction
you might think the algorithm is behind all of this no it’s autoplay on pc that the owner just leave it on for no reason
basically it’s random nonsense
10/10 no cringy intro or outro, no begging for likes, no stretched content. *thumbs up*
Great informative video with good narration and no unnecessary small talk, thumbs up and keep them coming !!
CZcams is seriously suggesting your channel, and I'm not complaining!
Please do a video on how to unbreak hearts. Thank you.
Its called pornhub
Saw a coast guard ice breaker going up the Hudson River a couple of years ago in February while I was eating at a river side barbeque joint. Thanks for the video explaining how they work!
I was a HH65 Dolphin Helicopter pilot in the USCGC Polar Sea out of Seattle, went to the Arctic and Antarctic twice. What a wonderful time and memories I have of that ship and crew.
You can buy touristic trip on nuclear icebreaker right to the North Pole.
*Reads title*
Me: "Well you gotta start small, like 'it's a nice weather out isn't it?' Then you insert a little humor for your current situation, or humor slightly off topic."
Huh, I always thought the captain stopped at the edge of the ice, then the entire crew got out with icepicks and went to town on said ice. After an hour, maybe 20 or so, the crew broke out a couple hundred bottles of fine bourbon or scotch and had a good time considering they were literally in Hell on Earth.
😂😂😂😂😂
I kinda like this alternate reality version of what it's like to be a crew of an icebreaker lol
I really like the scale model demonstrating how it looks under water
Thank you! Great and short video. Now of course I need to deep dive to find out more to sate my curiosity, but I still appreciate the quick answer.
I know this is very unlikely but what if the ship wasn’t heavy enough or the ice was too thick and it didn’t break when the ship slid on top. Would they get stuck or if not keep going or just reverse out?
This video make me feel like we can break it by hammer. Its so easy.
Thank you for this incredibly informative video. Keep it up!
Excellent video, clear, concise and straight to the point. No time wasted, all gains!
Just realized I’m a nerd 🤣 I’d like to know more about how the ship is made.
Nice dude
Thanks Drexter
Thank you ..I was just curious..and you have quenched my curiosity. .very informative video
lol, I actually learned ho ice breakers work from the anime 'A Place Farther Than the Universe' since the cast was on a icebreaker. The crew explained how it worked.
Here's your new favourite video:
czcams.com/video/2uCTLc5VuB0/video.html
😊
why don't they just design oil tankers to break the ice? or is it just more economical to get another ship to do it
Because most of the time an oil tanker isn't in an ice field and so the extra strength isn't needed. So all the extra weight and different hull shape would lead to too much inefficiency. However, an ice breakers only job is to break ice, so there is no inefficiency.
@@jamesmccann5644 ak47 I kinda thought so but surely theres a middle ground or at least it could be done for oil tankers that always travel through ice fields
@@mrplop38 Yes, the middle ground is ice strengthened hulls. There is a reason that it is done this way, and that reason is that its the most economical, and practical.
@@jamesmccann5644 ah makes sense thanks for answering have a nice life :))
@121bham you gotta ask questions to learn lol
hull thickness?? horsepower?? what makes them different from normal ships???
You started but did not finish this video.
Icebreakers are different from other ships in that they break ice. Normal ships do not break ice
Wow somebody can’t pay attention, he said in the video that the hull is thick enough to break ice, and it’s the design of the ship the helps it break the ice. There’s no set standard for minimum thickness and minimum horsepower all about ship design
@@johnappice4619 then why not make all the ships an ice breaker?
@@rizalardiansyah4486 money
@@johnappice4619 find that out your self this video is about how to ships break ice not about ships differences.
Just discovered your channel, and have watched most of your vids. I haven't seen one available on how ships are turned with thrusters, how many there are, and where they are placed. Maneuvering a ship has to be a beast.
Straight to the point, cheers!
I thought this is gonna be a 10-minutes long video lol
aint that cool, on land every hates each other but on the water a u.s. branch of homeland security escorts a russian tanker just out of seamanship and safety for all aboard the vessels.
Hmm 🤔 … they still have embargoes, don’t know if that’s been lifted.
Simple and easy to understand.
Thanks for it
And now im addicted to your channel subbed.
Icebreakers: *exist*
Titanic: Impossible
Why not design all ships that way?
Regular bows are more hydrodynamic
Different hulls for different applications.
Icebreaking bow is bad for fuel efficiency and sucks for handling of waves with waves slamming into it instead of it cutting water.
Further rounded egg shape like bottom of icebreaker makes very rolling prone ship in open water.
Also all the ice strenghtening and more powerfull engines/propulsion add (besides building costs) weight, which is away from how much cargo ship can carry.
Love your channel, keep it up!
I wonder if there are any negative environmental impacts of ice-breakers making passage? Wouldn't broken pieces of ice sheets and bergs drift and melt away given global warming temperatures and further/faster raise sea levels?
I guess it would increase the melting. Though they can only move through shallow ice, so I assume it would either re-freeze quite quickly or it would have melted anyway. Its an interesting consideration though
It's only sea ice
Icebreakers have broken up "Ice Dams" that form at the head of a rivers. Those ice dams cause flooding inland. The ice breakers break up the dam and let the water flow out, saving towns and property.
Oh ships break ice and we put the plane to global warming
I use the video as a good ice breaker for my next get together.
always the channels that you want to hear more from are the ones that keep short and straight to the point
Don't worry ice breaker. We'll help you reduce your work. Guys, let's burn rubbish and make global warming!
This was abysmally TOO SHORT.
This is one of the, key, reasons I watch your content but don't subscribe.
^Don't listen to this person, shorter videos are better. Every channel does 10 minute videos because of the algorithm but a 10 minute video for a 2.5 minute topic is just a waste of time
Immidiately got the information i clicked for without bullshit, thank you sir!
Short and direct. Thumbs up!
This video is perfect: short and objective. Question answered in no time.
It seems like everybody else but me seen this 3 years ago!! Well it was a great video! Ill see u guys 3 years from now!!🤙🏾🤙🏾🤙🏾
Useful video, thank you
Thank you sir for the explanation. Finally ive learn something new not everybody knew bout this
I worked at PWDD in Canadian. The yard built, while I was there, the M.V. Arctic and the C.C.G.S. Des Groseilliers. The yard also did refits on other coast guard ships, including put a bow thruster in the C.C.G.S. Griffon. Welding an icebreaker's bow is "interesting" to say the least.
Served on the USCG Polar Sea (WAGB 11) from 93-97. Went to the North Pole in 94. Awesome boat to be on.
Thank you. You deserve so many subs
Good one. Thank you. Keep up.
I saw the Healy in port in SF about a month ago. We sailed close up to read the name on her transom and got some nice photos. Don't know why she was in SF but the crew was likely happy. I believe she is the second biggest Coast Guard vessel. She's still not that big. I was impressed. Interesting ship. Thanks for showing her in action.
Hey, I'm subscribing, don't give up, your videos are blowing up in my recommendation
Thank you very informative non use of hard words for English beginners like me easily understood everything
I wanted to like this video because I served on the USCGC Polar Star. Being part of the crew and actually watching and feeling it breaking the ice was impressive.
Stats: Polar Star
Can break ice around 20ft thick.
3 screws with diesel electric engines and 3 turbine engines for breaking heavy ice. The hull is significantly more rounded. She listed port and starboard about 45 degrees each, the crew was literally walking on the walls while navigating the southern ocean.
Hull is about 1.75 inches bow and stern (44mm) for ice protection, and the keel is shallow so that the hull can smash ice with low risk of damage.
18 knots max speed under normal engines, over 20 knots for bursts of speed to plow heavy ice with turbine power.
Thinner ice can be plowed at approximately 3 knots, but backing and ramming is required for thick ice.
The ship would ram ice and about half of the hull was out of the water before it shifted about 3 degrees port or starboard before falling down on top of it. Personally experiencing that was like a roller coaster.
It took about one month to break the fast ice around McMurdo in Antarctica.
Healy is a medium icebreaker and is sent to the arctic to deal with parts of the ice for shipping through the northern passage. Polar Star is sent North to finish clearing the ice path, and then south to clear the ice for shipping vessels bringing resupplies to the science stations. Average deployment time is about 3 to 4 months, with two months of drydock repairs in-between. Deployed during the respective "summers" for each hemisphere, so they can operate during daylight hours.
Love your videos. You should make a video explaining how a wave can break a ship in half.
Nice, cool, short and of course a good explanation of the topic!
I’d love to see a more in-depth look at icebreakers. Thanks so much for this video!
Wish it was longer, fascinating!
I learned about this while touring a retired USCG ice breaker in Mackinaw City, Michigan.
That was so cool. Thanks mate
This is what all CZcams videos should be like! Quick and to the point. Answer the question in the title and didn’t start with the history of ships traversing ice fields
Such a great info in a very short video Wow
Wow he gave that information quick and direct
Already watched it first .... Very interesting indeed 👍😉😉😉 😉😉
2:23 Minutes of useful Information without ads.
Thank you.
Digging the channel. Nice seeing a video that’s not 23 minutes when it should be two. Well done
Great information thanks
