- Hyundai built under license of a MAN B&W 12K98MC marine propulsion engine
12 in the engine code is 12 cylinders or units
K is the engine code
98 is the piston diameter in this case 98cm
MC is engine series
The stroke of the engine is 2800cm or almost 10 feet! The piston travels straight up and down and is connected to a 2nd connecting rod that rotates with the crankshaft

The amount of designing, fabrication and installation of all that heavy engineering is mind blowing.
u know the engine is big when the inspection cowers for the crankshaft are roughly the size of Normal house doors. Lovely video
this 2 stroke is available in the arctic cat 2025 catalyst and riot.
Man, you got a good shoutout from Sal on What’s Going on with Shipping the other day. You and Chief Makoi really do some great videos. I have been a pipe welder/fitter and fabricator for many years and I do enjoy seeing how the machines work that enhance our lives. Thank you for bringing us along. Much love from NC🤙🤙
I appreciate it
I could (and almost did) fall asleep to the sound of that engine. Thanks for the tour!
I started sailing in 1974 with steam reciprocating stand by machinery. I was born a generation early.
It's clear that your SOP includes regular drills, maintenance and testing of emergency systems and procedures. The engine's statistics, over the long-run are absolutely incredible. The calibre of your replies to so many questions is impressive. I'm one Sal sent; may I suggest you get 'prepared for the YT onslaught'... I think your channel subscriptions, watch-hours, (then Patreon?) and time for replies are all going to dramatically increase!!
Chief, I don’t know how often you practice an emergency backing bell at speed, but it would be a nice video to record. I don’t believe many understand the technique required to air slow / stop the shaft against a free wheeling prop and restarting astern. That’s a real challenge with a direct drive slow speed diesel!
Yeah been there done that for real. You use all your air! But it will go! FYI it’s much more reliable on the automation than doing it by hand
Aloha Chief!
I am a QMED, and I have been on a lot of steamers in the past 10 years. West Coast, on the Horizon ships (Pasha) I was on the Horizon Spirit, and I think it was one of a very few steamers left! If you remember the Horizon Reliance, they just converted it to a LNG/ Diesel ship.
That's sad to see all the steamers go away! Most of the Engineers I work with were MEBA, and the Government MARAD steamers are AMO.
Nice channel! I'm home on vacation now. Aloha from Hawaii!!
Aloha! Yeah I did an emergency fill in on the spirit last summer, apparently I am one of the only guys with a license left. Beautiful ship great trip to Hawaii
@steamman9193 Wow! I must have just missed you!
I was on the Spirit from July- November last year!
Was the SSTG gone yet, or still there? We ran the SSDG 24/7 for about 3 months...
I was the 8x12 OMU...
Oh wow yeah I was there when it died. I was already signed off walking towards the gangway when there was black smoke coming out the stack. Had a few hours to get to the airport so went down and put everything back on. Last I heard it got wet and fried
@steamman9193 Yeah, it was down hard! They took the whole generator end off the ship and sent it to a repair shop. Progressive Electric. It was gone when I got there 7/3, and not yet back when I left on Oct.18th.. C/E Justin R. was there when I got there in July. Did you meet him?
This is amazing. I’m 67 and it’s rare to be so astonished. There are so many questions, but I’ll stick with three (😅) 1. How many litres for a complete oil change? 2. What’s in the next room? 3. How many thrust bearings does it have and what type? Thank you 🎉
1. Oil level kept Probably around around 60+ cu.m. (slightly above low level alarm in order to monitor any oil loss in the system). These are crosshead type engines so there should me no oil losses (except from the L.O. purifiers and minor oil leaks). No scheduled oil changes required for Main L.O. system, again because of the purifiers. There is also 6monthly Oil analysys that complies with flagstate/ class requirements.
2. Normally the M/E sits in the centerline of E/R with 5 levels- cylinder head level, 2 levels in the mid platform, bottom platform, and tank top level. Around the M//E for each level are machinery space protected with bulkheads and explosion resistant doors (i.e. ECR MSB/transformer/HV room, Stores room, D.G. Room, Purifier Room, Aux Blr room, compressor room, etc)
3. Only one thrust bearing assembly with 2 thrust pads ( each for ahead/astern). These are located between the aft most Main bearing and flywheel.
Wow, the size of that beast!
Massive!!! A great tour, Thanks!
Pure MAN Power!!
Impressive. Feels like a very large ratio of engine per person on this ship. I gather most parts need little maintenance, otherwise this wouldn't work.
Absolutely it is a lot but this particular model might be one of the most reliable engines ever made
How did the moth (0:39)survive down there ? Incredible machinery to my unknowledgeable eye. Thanks for the tour. 👍
61mw !! That’s amazing, and at 100 rpm.
Amazing sounds!
So interesting to see.
Thanks for filming.
I'm stunned. Never imagined. Cheers!
Wow...!! What a Beast... Just ticking along there... Thanks man, good job 😊
Awesome Engine!
Thanks mate enjoyed
BRILLIANT - thank you
Oh yeah, it would be sweet to hear that baby run up from Slow to Full... Or manoeuvring... 😊
Simply put any engine that each individual cylinder has its own stepladder permanently mounted it’s really really big.
Fantastic 👍
Does a diesel power plant take up more or less space than a steam power plant of the same power? With direct drive diesels, how do they keep the ship at a stand still when necessary when the main engine is running? Great video.
Steam is much more compact and reliable but no where near as cost efficient
As @Steamman9193 said a Steam turbine is much more compact.
I have seen a (I think it was) 40 000 hp steam turbine, and it was basically a couple of cubic meters in size i.e. a couple of washing machines, that's it - crazy!
However the 2 boilers producing the super heated steam for the turbines (propulsion and aux power) was massive. I would say each boiler was maybe half the size of that MAN engine or maybe a bit smaller than that.
@@tjampman I was wondering about that. I believe there are other things taking up space on steam plants such as condensers, evaporators and reduction gearing. The other thing I was wondering about is if diesels are more efficient why aren't more being used in utility power stations vs steam. Maybe emissions?
5-Stars! 🌟🌟🌟🌟🌟 Sal sent me...
Great... Love it👍🏼
Nice
Τhis will fit perfectly in my car.
Slow & steady wins.
Good morning Chief,
Does this unit have a gearbox (i.e. reduction drive), or is it a direct drive to the screw?
Direct drive. Direct reversing. To stop the prop the engine has to stop
i always wondered about that too. thanks
WOW!
The sound of music!
Same engine as on my Boston Whaler
cool
Wow big money when things go wrong.
Big money when things are fine too, our fuel bill alone can easily exceed $100,000/day
Is it just me or did I hear a number of rev changes, particularly around the 3 minute mark. What's causing that, a change in load or a change in the commanded powersetting?
For some reason, I didn't expect an engine of that size could change revs to that extent in such a short period of time, especially connected to a prop.
Are you running bunker C in port or diesel fuel?
Fascinating stuff! That is one engine? With so many fittings, pipes and wires, there must be something going wrong somewhere after a few years of use, how do you monitor it all?
This is probably the most reliable engine type ever made. 12 cylinders is a lot to maintain but we get outside assistance when needed
93,120 HP... That is so difficult to fully comprehend that kind of output.
But the size of that room that it requires. How many levels are there? And it is larger than just the engine's area too.
Makes me wonder, about what percentage is the engine room, plus all mechanicals to support the engine, versus the rest of the ship?
Those are great questions. This is a very very rough estimate but I’d put 10% of the volume of the hull is dedicated to machinery that would include auxiliary spaces like bow thruster and steering. Now the main engine space is restricted by the length of the engine basically the core area above it and around it is un usable for cargo so in this case the house is built on top of it and auxiliaries run the entire vertical and you also get the width to spread out your auxiliaries like generators and cooling pumps, anyway vessels this large have fairly spacious engine room you can generally drive a pallet jack around easily.
Is the sound from the actual video or is it added?
That’s the live sound as recorded by an iPhone 13. This engine is not that loud
@@steamman9193 Thanks. It sounds great. Some of my favorite relaxing ambience sounds. Just great!
They are very Loud!!
That's one massive engine. Great video
Always wonder why guys here in the states waste time with puny pickup truck diesels, when they could apply themselves to the ultimate diesel......a ship engine.
Haha I laugh quietly to myself when people start talking about horsepower and they don’t have 5 digits in their number.
If this would be an "two-stroke" Diesel engine - .... why there is at 03:30 an rotating camshaft??!! Or is it for the steering from the "Injector" for opening the injector-valve and pressing Fuel into the cylinder??!!

P.s.
i was 27 Years on ships as Sailor and Maat! On See and on rivers! We had own ships in the family! And this sound is like Music in my ears! The same like by an DEUTZ-Diesel (RV6M545) - fpr smaller Ships (River)!
Because it’s a 2stroke with an exhaust valve and the fuel injection pumps are also driven off the camshaft. There are no intake valves and the engine must be supercharged/turbocharged to pump air into the cylinders
Wow, now that is a big engine! I am a farmer where 'just' a 1000hp engine is big!
Near the top, were there some spare valves and a piston?
Yes spares are at the top and front of the engine
Those are bigger engines than my Hyundai!
Wluld be fun to swap into my Hyundai i10! This makes about 1500 times as much horsepower 😅
@@AIRDRAC You could probably swap your whole Hyundai i10 into this engine 😅 And nobody would even notice 😅
@@2xKTfc Absolutely true! :D
At 3:08, what is the little table with levers and a wheel for?
That’s the hand throttle In case everything else falls
I would love to hear this thing at WOT in an emergency drill. How much % of throttle is still available from a motor like this at normal cruise speed?
Not much difference from the video the time between pulses is just a bit shorter 100rpm is the max. We used to run these things hard all the time until Greta thunburg and her group got involved
Howe many liter to change oil in that sump,you newer change oil , you purified oil and you add oil then you test oil , then you increase viscosity with oil additives and oil can last long time you consume 10% under normal load and bearing conditions.
About 90,000l. I’ve never added additives, purification and will top up occasionally but it barely uses any sump oil, however I normally burn 500l a day of cylinder oil
Does this engine in its entirety ever get replaced during the life of the ship?
Hopefully not! Pistons but really just the crown and rings are the largest replacement parts normally. Injectors and fuel pumps are smaller and much more frequently but bearings are usually good for life
Nice! I bet you could drop your ham sandwich on that floor and pick it up and eat it with confidence....
No pork Muslim crew.
@@thereissomecoolstuff Turkey ham silly..made from the turkeys soft skin under the wing..
@@fredliperson9171 love it. You got it.
@@thereissomecoolstuff I'm old but not "Biden" old. ..
@@fredliperson9171 That engine room was very Bristol. The CE is on top of it. No one from the public will ever see it, yet it’s treated like it’s buckingham palace.
Just curious, how much intake boost pressure do you run on these?
They’ve really got us limited for fuel economy and emissions but it used to run at 2 Bar or about 30psi
@@steamman9193 That's about what I ran on my 16l cummins truck motor actually ran very clean never over fueled or over boosted it had 1.6 million on it and never had the pan or head off it.
Same as the Dali.
Dali engine is significantly smaller this engine is 12 cylinders with a 98cm bore they had a 9 cylinder 90cm bore and 55,000 horsepower. Dali also has a more modern electronic fuel injection system that may or may not have impacted its ability to restart after blackout
How often do they clean in there? It looks awful clean.
It’s 1 guys job just to clean and paint plus we get others as needed.
So when you bunker, do you say "check the oil"?
There’s 90 tons of lubricating oil in that engine
Is this burning HFO or is there a scrubber?
Low sulfur heavy in the ocean, ultra low sulfur diesel in the eca zones
@@steamman9193 ohh dam the leaks when u go into Eca zones
SM what is the stroke on that engine?
2.4meters
How much fuel is injected into one cylinder on one firing stroke?
Just some rough math but 1 liter/cylinder/ revoltion and that’s at eco speed
Is this on a US flagged ship? I didn't think we gad any of those engines in the fleet?
Yeah we have at least 2. They are the biggest single engines I know of in the US fleet
@@steamman9193 On those RRF MARAD car carriers?
No, this is a containership that sails the pacific.
@@steamman9193 Oh I see, you must be MEBA!
120 HP only?
Hyundai man? MAN.
A MAN engine made by Hyundai
I hope they don't throw rod bearings like the small engines do
Where do you shovel the coal into?
Can you get a big kit for it?
Probably for $30,000,000
what’s the fuel burn per hour?
How fast are we talking about? The air police have choked this engine down but i ve done about 150metric tons/day
I'll take a steam plant any day
How much fuel does it burn per hour.
Really depends on how fast you go we are slowed down for fuel economy and it’s around 150 metric tons/day I worked it out for someone else it’s approximately 1 L per piston per revolution
This is European main engine only made in Hyundai factory under patent license.
I think they make most of them under license very very few are actually made in Europe
60 RPM
It’s nice to see Hyundai can make an engine that doesn’t blow up after 30k miles. Or can they? Lol
This engine has 105,000 hours on it and has been running for 19 years parts like pistons get replaced but the main is all original
Wow that’s good stuff. I was watching another guys channel and he was saying the engine is directly connected to the prop shaft. So for astern, you have to stop engine and run it backwards. Which makes sense why probably all those engines are 2 stroke. But my question is, is there some kind of reduction/transmission that allows the engine to run without turning the prop shaft? I would think there has to be something to disconnect the two.
what a noisy engine !
i would have difficulty knowing what normal operation sounds like.
i suspect its only music to your ears.
interesting content thank you !
This one is relatively quiet
Mate, 2800cm is 91 feet. I think you meant 280cm
Typo is 200cm stroke
Big old tar burner.
My shop teacher threatened to fail anyone who call it "2 stroke" Said lazy language is a sign of lazy mentality. And he was correct; Call it the correct nomenclature made understanding more thorough
Why? The manufacturer calls it a 2 stroke
Am I missing the VTEC and NOS….
