Just when you think you've gone down every youtube rabbit hole
"Channels should Channels and not rabbit-holes, this website is no good at all!" Props if anyone gets that reference.
And to think you could’ve been looking at photos of people you hardly know or care about and learn nothing ha. You should now look into why ships are red on the bottom and how it relates to barns got their typical red paint
I made it to 2:38
oy nice to meet you stranger......since we are both here we should introduce ourselves.
Yesterday, I learned how tuba mouthpieces are made. Tomorrow, I may explore refrigeration.
Slow steaming is a common practice that is often used when cooking things such as dim sims or dumplings.
Oh wait... nevermind.
Looks like I’m craving dim sum tonight. Thanks
Ha, I found this video because I am steaming seasoned chicken thighs in my rice steamer. I am smelling the seasoning as it steams and then read your comment!.
Lol
Keeps quantities ready to serve. Moo goo gai pan out the ying yang. All you can eat and dim sum.
@Aggressive Tubesock Are you sure its not a cooking channel, you knobgobbler.
The quality of your content more than rewards our 'slow steaming' patience.
Thanks Will
👏
I couldn't have said it better
@Agent J I had a flight instructor who used to tell me "You never want to be in a hurry to get to your accident."
"Slowly steaming patience" describes my brain as I have to watch 2 ads before a video starts...
In the early 1980's I had several trips where the ship would 'slow steam' . Yes it reduced the fuel bill, and emissions, but it could also increase the crews tip time dramatically. Most trips were on a 6 month basis with the company I worked for but one was exteneded to 9 months purely waiting for the retail price of the cargo to go up. It gets very boring and you end up looking for things to paint!!. We had a very spruce ship by the time we hit port again and could 'pay-off'. my Fiance was very understanding as We had to change the wedding date 3 times.
@Nick Butler Damn she's one patient SOB
how did become a sailor?
@@sunofpeter2 I had traveled extensively with my parents as a kid ( both in Royal Navy ). I caught the travel bug. Fortunately I had good grades and could choose which shipping company I would like to go to sea and also study to eventually become an Officer in the Merchant Navy. That was when the U.K still had a sizable M.N.. hope that simplified answer answered your question.
@@nickbutler7935thanks man, i have always wondered how one became a sailor, i just like other people's stories.
We have a saying: when one is sailing, all three in a couple are happy.
I suddenly wanted to add sails on those cargo ships , using wind and fuel together. Sounds fun :)
And rows. Recruit olympian rowers as business associates or something. No whip allowed.
While we are at, add jet turbines on it, solar panels and electric motors xD

It was made by germans in 2015, "SkySails". yachtshipyard.files.wordpress.com/2015/01/00-00111.jpg?w=623&h=470
But not needed now, cos oil price record low now.

Rigging and sails isn’t cheap. And the challenge would be skippers and crew will need to retrain to understand apparent wind and use of sails - bringing back the master of sails.
If it is blowing 45 knots, a modern large ship is going to be fine assuming the sea states aren’t insane. Put a rig on it and suddenly even without sails the windage will risk capsizing the ship.
My next tinder date will have a great time during dinner. "By the way, darling, are you aware of all the intricacies of slow steaming?"
How did that date go?
@@johan.ohgren Superb, I suspect
Most of the vessels upon which I served were designed for higher speeds (eg 17 knots) but were generally run at around 14 knots. Exhaust gas boilers were fitted that could supply sufficient steam to run a turbo-alternator that would cover the entire ship's electrical load at sea.
On slow steaming, there was insufficient steam generation so the shortfall had to be made up with a diesel alternator at part load- not ideal for diesel engines. Just another problem down to slow steaming.
Some diesels were prone to design faults leading to frequent and sudden failures. In deep sea, clear of all traffic, a blackout could be avoided by increasing main engine speed to generate more steam from the exhaust gas boiler for the turbo-generator, until another diesel (if available) could be started.
Slow Steaming is what your channel seems to have been doing for a while.
JK, glad to see you're active again! :)
yup
oof
The JK part hurts it
John Kennedy?
People act as they care for the environment then start complaining when their amazon package is a day late.
RubySapior that pretty much sums up our society
Girls recording their environmental protests with their iPhones, while wearing plastic clothes.
So what? You're not solving any problems either by making up this statement. Society even expects some of that environmental destruction by you, it's not like everybody is free to choose a perfect environmental life, no you lose things. And I'm not talking about your SUV or your whirlpool, I'm talking about jobs, friends and so on.
@@okdoomer620 "Society has flaws."
"And yet you participate in society? How curious!"
This isn't the clever rebuttal you think it is.
It's not like I'm waiting on it from China. They're the next city over sitting inside the warehouse.
But slow steaming would seem to decrease personnel labor efficiency and reduce revenue due to fewer loads being transported. It's complicated finding the right balance.
Exactly. It is such a fine balance.
Well, Labour costs are pennies compared to the fuel costs.
A large container vessel going full service speed abt 20knts will consume about 250tons/day of fuel oil, at a price 400$/tons, that is 100.000 $/day.
Labour cost, I dont really know, but lets say an average ship is crewed by 20 people earning 5.000$/month average, thats 100.000$ a month. (I think this avg. salary is too high)
So if they can half the consumption of fuel, by going 5knts slower, that would easily pay for itself.
imgur.com/plokxJO Speaking of sailing fast and cost of ships crew, I had to sign up and upload this old drawing to imgur...
@@tjampman The average salary of cargo ship crew members is 3,300 USD per month.
True; It is like driving a Car. When going way more than 130km/h you will get diminishing returns and if you go less then about 90/100 you will take longer than the fuel cost is worth so people remember: neither go too slow nor too fast. There is an optimal speed and it is probably whats set by the speed limit. No need to arrest people who go a little too fast or too slow though;)
He's back bois!
Why does this video got recommended to me, a person living in the alps and disliking the sea so much that I wouldn't even go there for holiday?
Anyway, it answered questions I didn't even know could be asked and I watched all of your videos and subbed.
But still, miss me with that salty water full of fish and ships.
Fish and ships? You're making me hungry.
Thank you for the pun that I didn't know I needed.
And how much of the things you own were ever on board a ship ??
JUminator I’m such a fat cunt I read the last bit as “fish and chips”
Bring back the old style merchant ships! Single funnel with boiler and engine in the center, barely making 13 knots 😂
13 knots? More like 8.
It makes sense though. Coal is cheaper than oil, ships run on skeleton crews, and personnel pay is comparatively low.
@@JaneDoe-dg1gv wow
The low pay, bad food, crooked chief stewards pocketing food money, roaches, no air conditioning, burlap bags stuffed with hay mattresses, punching carbon, good riddance to hell.
1950, Danish and Norwegian flag ships, $50.00- $125 depending on rating a month, 7 days a week, etc, etc.Looked good & romantic in movies only.
But then how will we deal with U-boats?
I was honestly worried you'd left TH-cam, but kept checking back every month to see if there was an upload. Now have been rewarded with my patience! Great content as always, hope you're doing well and keep making these videos 👌🏽
Thanks Daniel.
Most people: Slow Steaming for efficiency.
Me: Haha 50 knots go brrrrr
haha ship go brrrrr
Yet another brilliant video, such a pleasant content and delivery. I could listen to you for hours on end. Thank you! Your channel is wonderful! Don't change a thing!
Excellent content. I’m an airline pilot and the parallels are dramatic. Airplanes are designed for an optimum speed which varies somewhat with the cost of fuel, crews, and maintenance. We generally can go a bit faster to make up time but fuel flow goes up exponentially which could make an otherwise profitable flight lose money.
For long range flights we likewise can have scheduling conundrums: you can sometimes buy two aircraft that can barely cover a route at high speed but have much higher per aircraft and fuel costs, or you can do it a bit slower with much less cost per flight (or per seat-mile) but you’ll need three aircraft to cover the route. Given that widebody airliners can cost upwards of $200 million each on the high end, this can obviously make a given route unviable economically.
Stick to flying hehe get it?
Hi
Glad to have you back..
Its been four months since you last visited youtube...
Another exciting episode..
Thanks..🙏
Thanks Naveen
Good to hear from you again! It was worth the wait!
I watch your videos on playlist to help me fall asleep. Nothing quite helps me like it anywhere else. Glad you're back making videos! You have a soothing voice by the way.
I have just discovered your channel. Like a very good book one cannot put down, I watch one video after another despite it being well after midnight. I am learning so very much through your detailed presentations. Excellent!
Thanks Noel. Good to have you aboard
Thanks Noel. Good to have you aboard
It's always like a surprise when a new video comes 😇
You don't expecting it at a certain time... it just appears in your subscription box.
I didn't know that what I needed to calm down today was your lovely boat videos. I have no interest in ships normally, but your videos are fascinating.
Another thing I never knew I needed to know about ships. Love it!
A few years back we used slow steaming to save on fuel costs, however, most engines are designed to run at optimum rpm for proper piston ring sealing, combustion etc. the liner wear lifetime was greatly reduced, we fitted Teflon tubes ion the cooling water bores in combustion areas to raise the liner temperature (cold corrosion was another factor)
So the trade off with fuel cost vs slow steaming was not that simple. Also, adding on days due to slow steaming would increase maintenance, crew costs insurance cost.
Give me an engine at rated peak performance any day, they humm where as SSteaming they rattle and shake.
I'm going to take Bachelor of Science and Maritime Transportation soon and this channel truly helps me. Thank you lad.
Glad you find it useful Selwyn
I was going to take a bachelor of science, but then I realised it was B.S.
Good luck with your education and maritime career.
These videos are great! Relaxing to listen to but still very informative! Thank you! 👍
Amazing quality as always, keep up the great work m8 👍
Thank you Casual Naviagtion, Very cool!
Thanks The Computer
Welcome back we missed you.
Casual Navigation is the Wendover Productions of the sea. Love this channel!
Good to have some content ,CN. Nice work !
Hope all is well with you and the family and best wishes.
Thanks Nathan
I casually browsed your channel last night and thought "Oh he stopped uploading". Literally the next night you uploaded. Let's keep this ship sailing!
What does 'literally the next night' mean? Do you mean 'next night'? Why add the word 'literally"? Intelligent people are laughing at you when you add the word literally to everything you say. You just sound like a snowflake tit.
@@markfox1545This is youtube. People dont use grammar alot and talk casually.
Finally something non-depressing to watch. Thanks man.
Welcome back :) a great return.
I didn't even notice you left but I'm glad you're back
I enjoyed the b/g sound effects. You must've had fun with those!
I did. I like to take time to work on the details
Thanks for the video i am marine cadet and last day we just learned same thing in my marine engineering class ! :)
Well keep up the good work huh play attention at school I just finished my maritime school and iam now a second officer you can do it buddy 💪🏼💪🏼💪🏼
Very educational. Many thanks for the knowledge ☺
Brilliant to see you back in my subscriptions feed 👍
Cheers Max
You also might need to change speed to arrive at the correct tide height
Your voice is so calming. A little bit of me is jealous of your first child who’ll undoubtedly be getting read to sleep by you in the years to come 😂
A new video from you is always good news 😊👏👏
Finaly you are back!
Good to see something from you again. Better than watching all the depressing news about this that and the other.
Currently thinking of crowdfunding a pirate ship btw.
I especially enjoyed making it for that exact same reason.
How long does it typically take to script/record/animate/edit one of these videos mate?
Everyone gangster until they start saving 100 percent on gas by rowing
Or you could use the wind
They have metal sails in a few. Save HUGE amounts of fuel.
Can’t wait for the next video. Love your content
Good to see you back. 👍
Really interesting video. Funnily enough, the big three Japanese companies NYK Line, Mitsui OSK Lines and K-Line have formed a consortium called ONE (Ocean Network Express) to deal with the capacity issue on boxships that you were describing. You can see one of ONE's bright pink containers on the NYK Line vessel at 5:40. Sort of like international flights - there really has to be a move towards increasing the 'load factor' for these companies to weather the storm.
COVID has caused a real crisis for containership owners. Charter rates have taken a major hit, and it is broadly considered that there is going to be record amounts of scrappage in the coming months and years. That's another thing to factor in on the environmental side as ship-breaking still remains a deeply troubling business.
Another major factor is IMO 2020 and low-sulphur fuels. An environmental plus, but undoubtedly a challenge for shipowners. The global fleet has never been bigger, there's an oversupply of vessels, and we're going through the biggest demand shock in a century. Going to be an interesting few years!
Thanks for that nice and concise overview of the state of the industry. Cheers
Maybe we can get smart enough to limit the need for transcontinental shipping by making stuff in our own countries.
A result is an inefficiency in global market goods. As some country naturally have better doctrine/infrastructure/labor to make whatever best they are making.
So many reasons to be self sufficient
I don't think you're aware of micro-economics, my child.
What would we use to make that stuff?
@Big Wheel And sing to you, Downs syndrome people are crazy about music, still really bad shit.
Wow real great info will tell all my friends and family. So interesting!
Glad to see you back!
"Is it all about profit, though?" Trust me, it's all about profit.
Because profit drives efficiency, competition and innovation. Lack of profit leads to stagnation, less Innovation and less efficiency.

The mic is way too sensitive it's like he's got shit in his mouth.
"Slow steaming"? You mean the attitude me and my coworkers have towards the boss?
Wow underrated and informative channel, glad I came across it!
Good to have you aboard Akhilesh
Amazing to see your channel blow up in subs since I was last here. Well done.
Of course, operating ships at lower speed (thus diesel cylinder pressure) reduces stresses and wear on propulsion machinery, a GOOD THING.
The video suggests too slow might be harmful to the engine, like “lugging” a car in too high a gear.
"fuel prices have hit record lows."
Oh this aged like fine milk.
Good to see you back.
Welcome back Cap'n!!!
If someone designs a malleable bulbous bow to adapt to different speeds, they can retire the next day
Wouldn't be difficult. Not difficult at all
Summary: Running slower saves fuel and markets fluctuate. You're welcome.
fuck off
Thank you for the interesting and informative video. You also have a really pleasant and calming voice! :)
Thanks CsOH23
Yet another video in a recommendation wave great video u have a good future in youtube i love your style
2:17 Aviation companies: "i think we are on the same boat"
2 years later, and fuel prices have reached record highs.
So happy to see your videos again!!! It would be very interesting if someday the wind will be used again to move ships, sails or otherwise.
Cheers eurasianchica
I'm curious if solar powered ships are viable.
Wind is a proven technology for ocean travel, but it has some notable downsides.
Solar-electric vehicles would have more flexibility, since the sun is more predictable than wind, and the direction of travel is less relevant.
However a solar ship above all else needs a very large surface area in relation to the amount of power required to move the ship. (thus encouraging the lightest possible ship with the largest possible deck surface area)
I suppose this is unlikely to work well for freight transportation.
And given the design constraints it would seem the most obvious candidate for testing this would be catamarans...
I don't know why but TH-cam has been recommending your videos, and you know what I'm not even mad. Your content is great.
robo shipping would be awesome in a pirate story.
- I da captain now. surrender da ship!
- I’m sorry Dave. I’m afraid I can’t do that.
Doors have been locked and ventilation has been shut off. Good luck.
Well, we went from the record lows to the record highs in fuel prices
Very thought provoking video. Thank you for making this!
Wow!!! I love this channel. It's so educating.
so, what you are saying is ... the "Slow boat form China", instead of taking a week to 10 days will now take 3 months, as it did back in the age of sail?
No, that would be far too slow. Regardless of economic conditions, shipping companies need to balance the pros associated with slower speeds with their cons: while they'd save fuel at slower speeds, they'd also get paid less per ton-mile, have a harder time finding customers, need extra capacity and need to pay more for crew among other things. The newer, slower speed is just a compromise between all those factors. 3 weeks is likely too much of a slowdown
@@hydrochloricacid2146 Agreed! well said, thank you.
3:33 "positive impact" on marine mammals... well : saying a "less worse impact" would be more correct. :/
Little Joe is seen hitting his hand with a hammer. Every time he hits his finger, he shouts out with pain. Guy asks him: "doesn't it hurt"? Joe says "Sure as hell it hurts, this is a hammer I hit my fingers with you moron" Guy asks: "then why the hell are you hitting your hown hand with a hammer?" Joe says "sometime I miss it and man, that feels fantastic".
So much about positive impact...
Less Impact, worse' redundant
@@KOZMOuvBORG pleonastic, rather than redundant. They're almost synonyms, but redundant means something repeated, while pleonastic means something unnecessary.
yay Casual Navigation is back.
Great content! Will watch some more of your videos.
Where were you? I missed you!
Cheers LeylandRhys. We had our first baby, so I ran out of time to make videos
Casual Navigation Oh Wow! I didn't even know that you had a baby.
@@CasualNavigation well done hope all well
so you joined the sleep deprived club he he
Casual Navigation Congratulations on your exciting family addition! I hope you are all healthy and happy.
Ho
Would it be possible to have an adaptive bulbous bow?
One that changes it's length/height in front of the ship to adapt to the speed of the ship therefore making it more efficient at multiple speeds, and more efficient overall.
Unfortunately not as the cost of implementing something like this would far exceed the vessel's budget, and any frontal collisions could lead to expensive repairs. I doubt there would be any real tangible savings from this in the long run anyway. Owners would rather wait for the rolling out of green engine technology which hopefully we'll see progress on later this decade.
We missed you casual navigator!!! Glad to see you steaming out of port again!!
Congratulations on 200,000 Subcribers!
You said that less noise is positive... I'd say it's just less negative. It's still terrible.
Interesting Fact!
Titanic steams at Full speed back in 1912.
Correct - I believe it was to make up for lost time. This ended up being a factor in the accident which sank it. Her speed ranged between 23 and 25 knots, making up to 77 rpm at one point. If they had stayed half speed ahead (approx 18 knots) They might have had a better chance of not sinking.
@@supertrinigamer Actually no, she never went full speed as the last boilers were never lit until the sinking. She wasn't running behind schedule, her speed during the collision was about 21 - 22 knots. It was just an unfortunate accident that happened because of outdated laws.
An accident due entirely to the mistakes of an incompetent Captain.
@@williamcooper9753 Would like to hear your reasoning
Siim Mumme ,
Captain Smith made the decision to speed through the field of icebergs and everything that happened afterwards came from that gross error in judgement. Other ships nearby took precautionary measures and had no problems. Not having radio communications or enough lifeboats or a ship designed for the type of collision that occurred worsened the disaster but did not cause it. That’s how I see it but I would be interested in other viewpoints.
Glad to see you back
Slow Steaming your way out of quarantine with a new video 💪🏾
"Is it all about profit, though?"
Basically yes, until governments _make_ companies care about the environment, especially companies like shipping companies that don't really have direct interaction with consumers. Because it's almost always cheaper (and therefore more competitive) in the short term to not care about the environment.
Long term, though, definitely better to not ruin the place we live.
2:33
Alright - what I am about to say is meant to be kept a secret. Just between you and me here in the comments.
I have a foolproof method to make tons of cash.
Drive your ship in reverse, so it will go -10knots/h for example.
By driving with negative speed, you will actually gain fuel, that you can sell once you have arrived at your destination.
I have spotted a flaw in your plan.
If you're steaming with negative speed, wouldn't that mean you will arrive at your destination before you've set off from your origin? Too much of that sort of thing going on and we'll break physics matey. 🤔
@@sixstringedthing
God dammit! It have been 3 years! I have used this exploit for 3 years without anyone ever taking notice or becoming suspicious. I have made a fortune!
