I love how everything is so plainly named. "What's that?" "That's the oily water separator" "Cool. What does it do?" "Are you serious?"

I was an engineer on a USN ship with gas turbines. So many similarities, just substitute gas turbine/diesel. I agree about the generators.

Chief, you’re a wonderful teacher.

As an Electricians Mate in the US Navy back in the 1960s, I felt we had a better overall knowledge of, and access to, more of the ship and it's machinery than perhaps any other enlisted members of the crew. I wasn't particularly excited about being made an electrician early on, but towards the end of my enlistment, and service on three different ships, I realized how fortunate I had been.

This is a view into a world that very few people know about. Cargo ships affect most of the world's population but how the system works is only known by a few. Your videos changed that and exposed the rest of the world to how ships, crews, and the interaction between the two actually work. david

Thanks Chief! I served onboard a Spruance class destroyer, and we had LM2500 jet engines for main propulsion and the generators. I was in Auxiliary division where we maintained the HVAC, compressed air and hydraulic systems. We also ran the evaporators underway for the fresh water. Brings back lots of memories! 👍👍

Great information Chief! I am a second engineer on the Great Lakes in the USA , very similar plants, we use mostly medium speed diesels that are coupled through a reduction gear for correct shaft rpm. Also we have pto generators hooked up to the main engines that we use while we are underway or discharging our cargo. We too have generators that can be used to run the unloading system or just house supply. Sometimes when racing a boat to a port we can put the house electrical need on a generator so we can gain 0.2knots so main engine doesn’t have to supply the power to run pto generator to main bus. Take care and thank you for showing people our world

Thank you Chief MAKOi. I've watched all your videos and had a glimpse of what my father's life is onboard. It actually made me cry that the sacrifice of not being with your family is just scrubbing the surface of what really is happening behind the scenes of the comfortable life he provided to our family. Again, heaps of thanks in providing this quality content to us. I'm your avid follower now and will continue to support more of your videos from here now on. Cheers! Maraming salamat po.

I worked on every one of those systems in the USN. I absolutely loved it. Thanks for the walk down memory lane, Chief!

Excellent, absolutely amazing how many systems are needed to propel a ship, heat management at its finest. Thanks for sharing.

Hello from Oregon, USA! I discovered your channel recently and have really enjoyed your sharing of the details of your ship's systems! It is rare to get this kind of access to the systems of modern commercial vessels, and you do a great job of sharing many aspects of the engineer's world, jobs, and experience. Thanks for sharing this! Cheers from Oregon, USA, Philip

I really appreciate the way you deliver your videos, not rushed, enough space and time for me to understand your information, structured and methodical and spoken with a very likeable voice. Thank You. My Grand Father was a chief engineer in the Merchant Navy during the 1920's on 6,000 ton ships that travelled from Liverpool UK to China and South America

This is why I love youtube. I'm retired & I'm now learning so much about things I sort of knew but to actually see what it takes to run a ship is so interesting. Thank you Chief. Congratulations on getting to 50 million views on your channel. Hopefully, youtube give you something more than just a plaque.

The thing to remember about Diesel engines is that they will run on any fuel they can atomize. In fact, Rudolph Diesel designed his prototype to run on peanut oil.

It is absolutely astounding and fascinating to me to learn of the incredibly high levels of technology and complexity in the immense infrastructures aboard these huge vessels. Thank you for sharing these remarkable insights into the life of seafarers.

An interesting video would be to explain the complicated steps required to restart a ME and ancillary systems after a total black-out, with no starting-air in the accumulator tanks and no running generator.

Cool. I work in a electrical power plant and other than your engine spinning a propellor and our steam spinning a turbine and generator, they are very much alike. We have back up generators and HVAC systems, domestic water, waste water collection and fuel handling machinery as well.

Navy kid here ( born 1955 ) my father was a Chief Engineman in San Diego in the 60s running Marines to Vietman on a Steam Turbine WW2 liberty ship ( APA 222 Pickaway ) , when i wasnt Surfing or Fishing i was hanging out on the ship , LOVED IT , i have been a live aboard Yacht Owner and Hot Rodder for 40+ years , made a living Restoring Classic Yachts and Automobiles ( now retired ) Cheers from Padre Island TEXAS love your channel

So. A boy born into a maritime family. My Dad was (now retired) a Chief Engineer, originally with the Ben Line of Leith (dry cargo/liner), then Sanko Line (tankers/bulk carriers), thereafter Stolt Nielsen (chemical tankers), ADNATCO (crude oil/petrochemicals), Kvaerner (LNG/LPG), Teekay (crude oil) and finally Hoegh (LNG). I spent many of my formative years away with Dad, Continent/WCAF with Sanko, trans-Atlantic with Stolt, Gulf/India with Adnatco. I spent many months at sea, seeing things and experiencing a World none of my friends could even begin to comprehend. The engine room was my second home; I'd literally spend hours gazing at the enormity of its operation, soaking up the heat and the scent of the engine room...and wait impatiently for 'Beer O'Clock' (1600hrs). It's no surprise I went into the shipping industry myself. My father didn't want me to go into a career as a deck officer as, in his words, "it's not the industry you see as a supernumery". My passion and interest in commercial shipping ended up in me becoming a shipbroker, a position I've enjoyed for some eighteen years now. My experiences and education being at sea with my Dad, I think, gives me an edge beyond that of my contemporaries and competition. The hugeness of what I do, the responsibility of my position, and the role I play in deciding where one crew member ends up in the World is not lost on me at all. Whenever I travel, I try to do so by sea. For example; I'm located in Rotterdam right now, my company based in Hull. Rather than fly from Schiphol to Humberside within a few hours, I'll take the overnight ferry from Europoort to Hull. More time, but I adore being on the water. I love the smell of the sea, the funnel, the writhing of the sea, and the vibration of a colossal hunk of steel crashing through the wrath of the sea. So glad to have found your channel. Interested to know which vessel you're on though, appreciate you have to block names/companies out. Is that Mastermind Management's logo on your boiler suits though?

Wow that prop shot is cool!!

Fascinating as ever ! Really look forward to your output.

This is why I subscribe (and encourage others to subscribe too!) Excellent, factual and concise presentation of what we need to know. Each of those subsystems will need their own full-length presentation (especially the generator / electrical power systems - including the very non-trivial problems of connecting to shore power (and things like galvanic isolation). Excellent stuff as always Chief!

That was very interesting. That ship looks spotless. Thanks a million for those explanations because I'm one of those who thought that bodily refuse was flushed directly into the sea. 👍🇨🇦👍

this is the first time I see a detailed explanation of the process, I could easily keep watching your videos all day , thank you very much and waiting for another episode 🙂

Chief, your explanation was great! After you retire from work on the seas, you will have no problem working as a narrator for documentaries and such. Also, I think your whole crew is great how they all work together and enjoy their jobs.

Years ago as a kid on Vancouver Island BC, any time we took a BCFerry anywhere, the engine room doors to the car deck were often left open. I would hang out at the doorway catching all the sights, sounds and smells of diesel fuel and the HEAT wafting up through the companionway! Ships are a real living being!

Great episode! I love the videos that focus on engineering details.

I was hoping someone would make a channel like this. I love to watch the ships come & go from the harbor & have always wanted to get a look behind the scenes. Thank you Chief!

I love learning about ships, and who better to learn from than Chief MAKOi the chief engineer!

Hello, Dear Chief.. Actually, I'm a mechanical engineering student,2 years left to graduate and confused about my future career field .Having binge-watched contents of you,my trajectory of career path becomes more inclined to Marine Engineering.I would like to thank you for creating quality contents and really enjoy watching them.Looking forward to new videos while watching ones I haven't yet.😇

I toured a Japanese freighter's engine room once. The pistons were so large. Alot of thought goes into making everything work.

Sir chief hope one day GQ would interview you and rate how realistic are their about Ships in movies etc. Everytime I'm doing reviews for interview, I'm refreshing myself by watching your contents ! God bless

Instructional and entertaining as always, Chief. Thanks for all the hard work you put into the channel.

Fascinating details! I noticed a watch stander using a steel rod to listen to the fuel centrifuge - pretty cool way to make sure it's running OK!

Definitely the electric generators are the most important thing onboard. I heard many scary stories about dead ships and how difficult is to recover from a dead ship situation; completely different from the dead ship test/exercise you do during new build or drydock operations.

“Where does the poop go?” -commercial for All Bran plays.

I love the video were you went home and chilled with your family...my thumb nail picture you see is me coming home after many months at Sea on a fish processor in Alaska.

Always love your videos chief. So informative I wish I was 40 years younger but those days are long gone all right my brother continue I enjoy your videos love ya

Wow Chief! That was super fascinating. I can't wait for the future videos that delve into the systems. Thank you!.

This is such a great overview of the systems in an engine room and how they are connected. Really nice chief!

Hello Chief Makoi. I've been watching your videos since 2015. I was just a nautical student and now I've finished the academy. 4 days remain for exam 4/E. Your videos are very useful :)

I am a fresh graduate marine engineer.. I am telling you that I have learnt from your videos and simple explanations about ship's engine more than I have learnt in a 5 years college. Sir.. you are great♥️ I hope someday to work with you on one ship🙏🏼

This was a fabulous rundown of the ships engineering love this stuff.

U have the perfect ship channel for me, all the facts bro! Thanks a lot!

Good pacing, easy to follow, thank you for this video.

Soooo complicated 😄 ! It's like a self-contained city 😊 . There is just so much going on. It's an enormous responsibility for the Engineering Department. As the Chief commented in an earlier video, the Captain runs the ship, but the Engineering Department makes the ship run 🙂 .

It's all so amazingly clean. Good job.

Thanks so much Mr chief Makoi for these very helpful videos !!! I'm going on ship next 2 months and work as helping engineer(at lowest level) My English is not good so I learn English for marine engineer through your videos,translate all what you say and remember it And of course my target want to be chief engineer like you One again thanks you so much for all helpful information and knowledge about marine engineer,please keep your posted Wishing you goodhelt and happiness

A very straightforward and thorough explanation of marine equipment. Mister you sure do know your stuff!

As a mechanic it boggles my mind how much knowledge is required to be able to troubleshoot and repair so many different technologies, all while at sea, with no “parts delivery” possible.

Pumps, boilers, desalination, sewage plant, purifiers, HVAC, refrigeration, more pumps. You guys are very well rounded.

Aloha Chief! I love your videos! Keep up the good work and may the winds be at your back.

Excellent narrator. Can listen for hours. Reminds me of Fred Dibnah.

Sound like a fun quote for a t-shirt: "Where does the poop go?". Thanks for your elaborate and clear lecture. You are a gifted person.

I have worked at a number of Power Generating plants and nuke plants. One time on a long job the big boss, went with a couple of the foremen and their wives on a ocean cruise! :) Apparently the big boss, spent most of his free time in the engine room and below decks, talking the the engineers and guys who ran the ship :)

I am disappointed you didn't mention the most important auxiliary system in Engineering Control. The coffee pot. Ships don't run without coffee!

Evening Chief, Many thanks for your time to make your very interesting films. I have also seen other films about the merchant navy by other film makers, the information and quality of your filming is outstanding in comparison. Thank you and also to your crew. Rgds. Peter.

I know I've said this before but here I am a 53yo mother of a teenager and I watch all Chief Makoi's video. And I have preach many times when you hit on something that I can argue about, lol! So yeah you my bodyguard, without the body! Imma badass when I know what I'm talking about, EYEROLL🙃🧐😏! From your bestest, southern U.S. couch potato, Blessings to y'all!!

SHALOM BROTHER MAKOI. THIS IS A GOOD WORK. THANK YOU. GOD BLESS YOU ALL IN THE NAME OF THE LORD JESUS CHRIST. AMEN.

I love you videos! Thanks for posting them.

Chief please make a dedicated video on food that’s served on ship covering all 3 meals and special meals on weekends and festivals.

Nice and clean engine room Mate

Great video, Chief. The engine room is one of the most interesting parts of the vessel, where one can really see the intricate dance all the different systems and subsystems do in order to make the ship run.

Thanks for making all these. I am an Engineer in the power industry and there are a lot of similarities in equipment used. Great work!

Worth mentioning that the oily water separators for the bilge water are actually controlled by an electronic "white box" (aka the witness box, aka the snitch box) that is behind a tamper-proof locked cabinet that only the chief engineer holds the key to. The purpose of the white box is to test every single discharge of bilge water from the ship and log the (passing) test results electronically in an encrypted format for future inspection by port authorities. It physically prevents any discharges that exceed the MARPOL regs for oil content. It also logs any attempts at tampering. Gotta love how the powers that be didn't even preserve the illusion of voluntary compliance. They care more about bilge oil than crew safety - why no snitch box to ensure the crew gets fed every day?

oh man I'm so glad I don't have to burn the heavy oil anymore. Like you said it is a pain to work with

What a great overview, I'm loved "where Does the poop go?" ....I like this guy, Knowledgeable, and knows his systems.

The shots in the introduction of the screw turning under water were gorgeous. Thanks!

Time to binge watch lots of episodes. Well thats my Saturday night sorted. 🙂🙂

Great video Chief. Fascinating.

and here I am , awake at 4am in the morning. Your videos never cease to amaze me, the documentary style approach. Great content chief!

Thanks, Chief. I always learn a lot.

Love ❤️ it Keep up with educating us, love it absolutely love it very interesting

I am blown away by the number of systems that you are responsible for, in terms of operations, maintenance, and repairs :O I thought I had an idea of what you do; I was wrong by two orders of magnitude! As always, a great video in terms of educational, entertainment and simply enjoyable. Thanks for sharing!

Sir, as the dad of a soon to graduate ME from Massachusetts Maritime Academy I want to thank you for educating me in the life he has chosen. He's already worked with steam (TS KENNEDY) and both diesel and LNG (Crowley TAINO) so we feel blessed that he's been introduced to the three big players. He's done some long watches, been bounced around in some nasty weather and is still sure of his career path. Stay well.

Your comment abou th generators being the most important equipment on this ship was certainly borne out by the Dali .

This is great, looking forward to this series.

These episodes helps a lot for the newbie seafarers like me. THANKS A LOT for this vid sir. More video to watch 🤗

I have to repeat a quote from you in a previous video ... "The Captain runs the ship, the Chief Engineer makes the ship run!" I have used it often since I first heard you say it! Keep up the great work you do, and keep inspiring new Seafarers to choose a career at sea! FYI: My wife's father was a Chief Engineer aboard an Atlantic dry bulk carrier when she was a small girl from Workington, Cumbria in the UK.

Missed you! Always great to cruise with you!

Thanks for sharing chief makoi Excellent🚢

The fruits of knowledge should go to everyone. Thanks for your endeavour in this direction

I am a big fan of your videos. I love them. Good job. Etukudo from Nigeria

Thanks Chief, your videos are very interesting, keep em coming!

I learn so much every time I watch your videos! Thank you!

Thanks Chief. I'm a retired seaman working mostly in the engine department I love seeing those working machine s. It was nostalgic I can't think of a better profession than seaman. I just wish I may have time to return to the job I miss before I close my eyes forever.

Chief Maroi, Thank your for your detailed explainations of many things that are part of what it takes to make a ship run smoothly day to day. Wendy

Thanks, Chief! It's fascinating to get a glimpse at what goes on behind the scenes so to speak!👍

As a former 3rd engineer, I find your videos amazing and they making me wanting to go back to the sea. Keep it going chief

this is one of my favorite episodes, love your technical overviews Chief!

"...Some of you have wondered.. Where does the poop go?" /click!/ Range rover ad starts rolling immediately. Epic sequence, ROFLMAO

Chief, had you been making these videos thirty years ago I would've pursued a life at sea. They are the most educational videos in the short format on the subject.

Another great informative video Chief thankyou. 😀👍

Chief tank you for the explanation all the support from us , please gave us the details of each machinery , because we are marine engineering Cadet , and thank you are the only one who gives me the information to pass marine engineering exam

Salamat po sa dagdag kaalaman sir Eto yung mga content na gusto kong panoorin. Mabuhay sir

As a former maritime engineer so much study for relative short working life ,now retired and wonder where my old mates ended up.Iam on the bottom of the world 😆chief Maiko interesting videos

Very cool! But the more information you gave the more questions I started having LOL! - Like most jobs along these lines you don't need much training when everything is working correctly so I imagine it's the extensive knowledge needed is what do you do when things go wrong. This poses the question of redundancy and your abilities to solve your way out of many problem scenarios. I look forward to this line of content from you Chief!

A clean engine room, very good, great video and detail explanation Thank you Chief, God bless you

FANTASTIC video Chief ..... It taught us a LOT, and answered many questions as well !!! You are a damn GOOD instructor, sir !! Safe travels to you and crew ....

Tnx Chief Marami akong natutunan hoping na mas maraming vlogs pa Po kayung maupload para magkaroon pa Po ako Ng knowledge about sa pagmamarino btw I am aspiring seafarer Po and BSMarE Po Ang kinuha kong course....
