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?
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

Nice pi.
The question was, how do Icebreakers break ice, not how they are build and look.
@A. Wellknownmyth
Apple pie ?
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.
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
@@clementwolf4081 it's 2022, you do you
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
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.

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.

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.
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.
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
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. 😂😂🤪
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.
It’s 4 am and really care about ships , but here I am , this was fascinating 😊
I love the short, concise content. RUclips 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.
The ending was so sudden... no misc info, just; “it has a fancy bow”. Splendid
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.
RUclips is seriously suggesting your channel, and I'm not complaining!
10/10 no cringy intro or outro, no begging for likes, no stretched content. *thumbs up*
Developers should look into changing RUclips's algorithm. Why RUclips didn't recommend this channel to me before. Subscribing right now
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 RUclips 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!
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.
Wow! The way it’s done completely surprised me. Thank you for creating this video.
This is what all RUclips 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
I was on WAGB-10 Polar Star and it was an awesome experience.
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.

Great informative video with good narration and no unnecessary small talk, thumbs up and keep them coming !!
oh I love this straighforward right to the point video like this one, you are just the best
Immidiately got the information i clicked for without bullshit, thank you sir!
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:

Excellent video, clear, concise and straight to the point. No time wasted, all gains!
Beautiful clear explanation!!!
Thank you for good video
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!)!
I always thought it was just ships with reinforced hulls that ice can't break. Never realize there was a technique to it.
Digging the channel. Nice seeing a video that’s not 23 minutes when it should be two. Well done
Straight to the point. Thank u.
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.
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.
always the channels that you want to hear more from are the ones that keep short and straight to the point
That was very informative, cured my curiosity, nice short and sweet thank you.
Thanks Craig
I learned about this while touring a retired USCG ice breaker in Mackinaw City, Michigan.
Please do a video on how to unbreak hearts. Thank you.
Its called pornhub
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.
*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."
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 .
This video make me feel like we can break it by hammer. Its so easy.
Thank you ..I was just curious..and you have quenched my curiosity. .very informative video
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 is perfect: short and objective. Question answered in no time.
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
I'm watching this because when I can't sleep I put my feet out of the bed covers, open the window, feel the draught on my bare feet and imagine my bed is on top of the ice breaker in the freezing cold Antarctic. I don't even know where this imaginary bed on a ship idea came from, but it helps me sleep
Well, sounds cozier then why I am watching being worried we don't have as many icebreakers as China now does! 😅😂😂
@@iliadiliad6028 maybe the demand for ice breaker beds is way higher in China 😂✌️♥️
@@evamurray4478 😂😂
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
Back and Ram baby! Served on the CGC Northwind Ice breaker, The hulls are also thicker than most and the newer breakers use a special steel that keeps its strength in polar seas There is no keel either to keep the bottom smooth which makes the ship ride rough in any seas.
Thank you sir for the explanation. Finally ive learn something new not everybody knew bout this
Nice dude
Thanks Drexter
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!
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.
2:23 Minutes of useful Information without ads.
Thank you.
Icebreakers: *exist*
Titanic: Impossible
Simple and easy to understand.
Thanks for it
I thought this is gonna be a 10-minutes long video lol
Served on the USCG Polar Sea (WAGB 11) from 93-97. Went to the North Pole in 94. Awesome boat to be on.
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.
Precise and concise. Thank you for clarifying the ice-breaking process.
albertus
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.
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
Oh ships break ice and we put the plane to global warming
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.
Don't worry ice breaker. We'll help you reduce your work. Guys, let's burn rubbish and make global warming!
Wow he gave that information quick and direct
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
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 worked in a shipyard when an icebreaker ship was being built, your right about the weight of the ship breaking the ice, but also in the bow is at least a 6" diameter rod that is built down the bow too! The bow is heavily strengthened with it.
Before i watch this, i want to say that my thought's were that they had a particularly pointed fore end to almost slice the armour, with the hull further just behind that being designed to push the now split ice out of the way.
Turns out, i was partially correct.
Love your videos. You should make a video explaining how a wave can break a ship in half.
There is also ships that are capable operating in ice, but are not icebreakers. In Finland and in Sweden highest icerating for ships (that are not icebreakers) is 1a super. Those ships are capable operating and moving in ice that is one meter thick. Usually even those ships use icebreaking services because even they are capable to move in ice, it is so slow that icebreaker is good idea.
I thought it would be a lot more complicated than that... shorter video than I expected but definitely worth the watch
Wish it was longer, fascinating!
My friend is on the US coast guards polar star and it just runs up ontop the ice when it’s super thick and uses its weight to push down and cut the Ice, but about a good 30 foot of the boat is sitting on the top of the ice before it falls through
Hey, I'm subscribing, don't give up, your videos are blowing up in my recommendation
I’d love to see a more in-depth look at icebreakers. Thanks so much for this video!
Very short but answers the question very well
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.
This was usefull. I didn’t know icebreakers worked that way.
I use the video as a good ice breaker for my next get together.
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!!🤙🏾🤙🏾🤙🏾
Thank you very informative non use of hard words for English beginners like me easily understood everything
I always break the ice by just saying hi but everyone is different. Great content keep it up.
Was shown a video of the annual convoy to Antarctica some time in the 90’s. Also has the VHF radio traffic between the ships and the POLAR class icebreaker. At one point, the captain of an Italian ship comes on the radio in a very thick accent “ Ice-a breaker, ice-a breaker, I’m-a stuck-a!”
While working out of Gothenberg, Sweden around 2010 I attended on board a Finnish registered ship, the 'Tampura' as I recall, that had been built to break ice, stern first, in the Gulf of Finland. normal looking tanker apart from some rather strange features around the superstructure. Odd people with strange ideas live in Finland.
Short and direct. Thumbs up!
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.
That's exactly how our local swans break the ice. The male goes ahead and smashes his chest onto the edge of the ice and it opens a channel for Mrs Swan who serenely glides through the now open path through the ice. It's really impressive and beautiful to see. 🦢🦢
The short answer, not the short story made long. Great job, so basically it's the ship's weight that cracks (breaks) the ice.
Great info. I did wondered about this ice breaker. I did see the other video of the bow difference too. Good job
Nice, cool, short and of course a good explanation of the topic!
