Nothing beats a long stay in port and do maintenance without worrying about the need to finish quickly. 😊

I enjoy these behind the scene videos very much. The Chief and his 3 assistants are very busy all the time.

Great to see a very professional team at work. They're a credit to you, Chief!

I am sailing with MISC for previous long time ago. I have experience overhaul this B&W 6 unit cylinder Chief. You make my memories and smiling olone...Salute you Chief. Hope you always success for you seafarer live on board...

Just look how clean the Chief is at the end of it and how oily everyone else is. I think thats called experience.

As a car mechanic I find your ship maintenance videos fascinating, you guys are doing an amazing job!. Cheers from Canada

Makes you appreciate what these mariners do to keep things “moving,” in every sense of the word.

Quite the crew there, Chief. Those are the kind of folks I would be honored to work with and humbled to call my friends off the clock. Skal!

Chief - Great video with the first cup of coffee on a Saturday morning. I'm familiar with heavy equipment and aircraft maintenance (varied work life) and have rebuilt my share of auto/truck engines for myself. Scale difference is really noticeable but a diesel is a diesel and that looks like a good design - I've sure never been able to crawl in a cylinder bore or crankcase. Also your parts situation is different than us land lubbers are used to - you sure can't run to the local Chevy dealer for a set of rings. Really enjoyable for this retired mechanical engineer with lots of management experience - keep taking care of the troops the way you do, it's obvious what a good group you have. And that they have a good leader.

If i owned a ship, i would be honoured to have your crew tending my engines. Well done.

As a non-mariner tech I was waiting to find out how they would compress those massive thick pistonrings.... only to find out that gravity does the work together with the special 'circular' tool that is most likely conical/tapered. Really awesome! Thank you @chief makoi for sharing these vids with us 😊

I love the way your crew gathers for the "graduation" shot after certain tasks. That makes me feel they are proud of their work. Cheers from Liz and Ginger (pic left) in Australia.

This is a working world most people would be unaware of if it wasn't for you. Really fascinating, thanks for an interesting episode.

Nothing like a Saturday morning video 👍 Thanks Chief 👍🇨🇦🔧

Smallest guy goes into the cylinder liner? This was fascinating, the knowledge and skill it takes to be an engineer is just amazing. Thanks, Chief!

I was a deckape myself, but I have come to appreciate what you do down in the engine spaces. And this was especially impressive. Well done.

Absolutely amazing work, men! Thank you so much for sharing this with us, Chief. Blessings and safety to you and your entire crew and families. ✌🏼

A well-trained team makes this operation look easy. Working on automotive engines, I know enough to know that's definitely not the case -- giant precision machined parts, ~22k PSI bolt torque, and enough cylinder throw to create a human trebuchet, in a 37 C compartment. 😳🥵 Nicely done. The appearance of the team at the end was a nice touch. 👍

I love these videos. You never get to hear from people who actually work on nuts and bolts of what moves the world.

Your crew look like a bunch of real characters. True professionals, and good guys....

I love how you promote a friendly, professional, work environment for the crew under your command! A boss that manages people well will always develop a superior work product!

Thanks Chief, as a retired auto mechanic, I find the technology of these huge engines intriguing. The bore to stroke Racio is mind blowing.

Fascinating work, Chief Makoi! Engine guys from all around the world can identify with the work you and your crew are doing.

Great video, Chief. Not only that but it brought back some memories. 1972 I was a student of mechanical engineering in Germany and was send to Hamburg to do some practical work. I ended up in the dry dock of Blohm & Voss where two engine blocks were completely overhauled but because there was a huge time pressure as soon as one block was finished and running the ship was sailing to Rotterdam with us finishing the second block. The noise and heat in that engine room was awful but also enjoyable.

I assume that the relaxed pace that was allowed here gave a good opportunity for training too? Really good video. Thanks Chief.

Indeed, your piston is bigger than mine. Great video, amazing work

Great Video Chief... I wanted to be an Engineering Cadet with Shell Tankers when I left school but sadly I was forced to follow a different direction in my career, so I live my dream vicariously through your videos! God Bless you and your dedicated team.

I’ve just discovered your channel this week and have been binge-watching it. I was born in a landlocked country and live in another landlocked country. So all of this looks surprising and fascinating to me. Each of your videos expands my awareness of how much I do *not* know about the world in general. I have been ordering lots of goods (especially electronics) from all around the globe and I knew that at some point there was a cargo ship involved in the delivery, but I had absolutely no idea what such a ship could look like from the inside. Thanks for sharing all this information. I can imagine that it takes a lot of extra time and effort to make a concise and informative video out of many tens of hours of complex maintenance work.

Amazing. That is just a whole other level in engine repair and maintenance.

This is one of the most interesting videos I've ever seen. Always curious about ship engines, so this well filmed and narated video is just amazing. A big thank you, greetings from Sweden!

Thanks for the look inside the engine again Chief. Great job lads. Little things I see the engineers doing scream seasoned pros to me. For example, installing an o-ring and running the finger around it to remove twist. The special stands, tools such as the ring squeezer ring, all the fixtures associated with the process. The hole in the deck for the rod to drop through. I love it all!

Hey Chief! I'm an old steam boat engineer. I used to sail as Chief Electrician on APL C9 & C10's, with Big ol Sulzer Motors. They put out 59,750 shp @ 105 rpm. They had (don't remember exactly, but...) 910 mm bores. We replaced 2 cylinders of the 12, every 35 day trip. That was a chore that I was happy NOT to participate in 😅! I'd watch the Sulzer crew do it!

It's fascinating to see how the cleaning and replacement process of just one piston can take over 9 hours. This really puts into perspective the scale and complexity of marine engine maintenance.

50 cc moped owner here. Serious case of piston envy.

The shear physicality of the work is astounding. You run a good plant, Chief.

The hardest working engineers I’ve ever seen…

Love your videos Chief , you have a true gift of telling storys - narrating !! I have watched many of your videos with fascination despite being in a whole other profession . Be safe out there chief and keep those great storys of your journeys on the high seas coming our way !!!

Your crew are at the top of their game. Awesome content.

Love the video. I was a MRO storeroom clerk for awhile for a dairy plant. I would love to see a video on how spare parts and tools are kept on a ship.

Inside the crank case. W0W that is some big main engine Chief.

Minecraft didn't quite prepare me for pistons of this size. 😆 Chief, your crew makes this labor intensive task look so smooth and easy.

At the end around the table, I couldn't help myself from smiling. The Chief's coveralls were still white. The other guys' were all oily and dirty. It's good to be The Chief! Good work, guys.

I'm a lowly car mechanic,these films really open my eyes as to wot you guys do ......total respect

Excellent video Chief! I used to work by large Clark engines like this in a natural gas compressor station. Except they turned 300 rpm (high speed 😂) 18” bores, and crankshafts were about 30’ in length. Seems they are about 80 years old by now. Anyways, love your videos!

I missed this job as 1st assistant engineer @seabourn cruise line...I do really appreciate your blog chief ...very precise and clear.

It’s impressive on the tools available to the crew to accomplish the work. From lifting frames, guides, to stands seem to make the job possible and safer.

Excellent video as always and I must admit I'm surprised that you're still posting videos I figured you would have retired by now!!! 🤠👍

Dude, I'm a lic. HD diesel mechanic in Canada, (on road). I love these vids, always thought marine or naval engines would be super cool to work on..

👏 Well done with this team of talented expert crew. Safe voyages and clear horizons. Respect sent to you all. 👍

Outstanding as always!

So - pretty much like rebuilding the engine in my big-block-Chevy... except for all of it! Love how you can drop a guy INTO the cylinder itself for final cleaning! Incredible scale! My Chevy is jealous! Great video Chief - - that's one happy crew!

Well done gentlemen. Beautiful machine. Top shelf stuff...Made in Germany.

Thanks Chief. With your videos I get the opportunity to experience and see things that otherwise are not available to me. I enjoy every moment of this video. Thanks again

Well Done! You doing a great job! Thx for filming and editing for us here~

Thanks Chief for another informative video about maintenance of the main engine. You see ships passing by in ports but seldom think about all the hard work it takes to keep all the many different systems on a ship which are involved.

Chief, you have quite the crew of Filipino professionals!

Thanks Chief for another video showing the great knowledge and skills that marine engineers exhibit

Great video Chief. Great to se the team at the end.

What a great video. It brought back many memories for me, from over forty years ago,not much has changed in all those years.

OK, chief, next video, let's put a turbo to that engine. Great job. Greetings from Asunción Paraguay.

Beer 🍺 and BBQ 🥩🍖🍗after that.

Great job giving insight to the duties of the engineering crew.

much respect for the work you do, and much appreciation for producing the videos with commentary

Thanks Chief...while I am not a seaman I totally enjoy your videos, Your explanations make it easy for a novice to get a handle on the tasks at hand.

Great video. So much hard work is accomplished by everyone. Thanks and take care.

"Proper Preparation", ah yes, one of the famous 6 P's. From my own world (before retirement) of Union construction; "Proper Preparation Prevents P^&& Poor Performance" Thanks Chief great video.

A serious job, performed by a professional crew! Thanks, Chief!

These maintenance videos give a good look at what you and your team do. Thanks for the upload.

THANK YOU CHIEF AND YOUR GREAT FOLKS..SAFE TRAVELS..

Too think my job the other day was too replace my rotors and brake pads. Love making things work again.. Thx Chief makes it look easy ~

Cheers to the crew. 🇨🇦

Love how the ship have all the tools and spares and knowledge on board to conduct this repairs. An the machinery seems to be designed to help the maintenance. Great Vid Sir.

Hats off to that engineering crew they made that look like it was out of a textbook.

Teamwork takes a great team and a great team leader. You have both. I am impressed with your coordination and attention to detail. Thanks for sharing. 👍👍👏👏

Работая 3 и 2 механиком с 1983-90 г. на двигателе K9Z 60/105 E участвовал в подъёме 111 поршней.... Опыта в подобной работе достаточно. До сих пор " в дрожь кидает" от мысли, как можно было все это выдержать? Был молод, амбициозен, хотелось заработать денег....

Kumusta po chief and crew ? … another interesting video salamat 😊 I love the sound of the engine as she kicks into life ❤

Great video brother from the imperial county California 🇺🇲🇺🇲

Really detailed and accomplished job, I also compared as change a heart valve of aT Rex. I really love the care of all aspects of your job, congratulations. 🎉🎉

Thanks for the video. You guys need to get some twisting lockwire pliers. Makes that job neat and easy.

Love seeing the engine work!

Chief MAKOi : great video. Really enjoy these. God bless you, your family and your crew - John 3:16

Excellent Chief. Thanks to ALL.

Very interesting. Thanks for posting, Chief.

From the Y.T video on the Dali black box revelation video. All I can say that if it was maintained to this level of preventative maintenance schedule like this ship, it would be still sailing by now.

That's one big jeepney😅😅😅

Impresive work Chief, well done 👌

Another great video! It always amazes me at how many machines You and Your Crew have to be completely proficient with.

While these engines are huge, it's amazing how much work they are able to do considering how small they are relative to the size of the boat

It always amazes me that, compared to the size and length of the ship, how small the engines really are.

Thanks for the video. It's very interesting to see how these things are done. It's an important part of world infrastructure. Much appreciation to all the team being filmed, it means I can appreciate how something I have has been able to travell across the world.

Thank for these types of vidos. Kindly make one video on engine room piping systems.

Love Watching your crew in action

Thank you Chief impressive on board maintenance/repair work.

Good job Chief and Team!

Gone are the days when ships stay long in port and do main engine overhaul.

Great crew you have there!

Exxelente ....u are a tru chief....all the guys are a fine team. Good luck to u all 👍👍👍 Greetz , diesel repair Rotterdam

Well Done Chief and Crew members. Thanks for sharing this information. Best Wishes to everyone, their Families and Friends.

Very enjoyable and informative video. Thank You.

Tapered ring compressors are used in automotive engine rebuilding too. The disadvantage over adjustable sleeves is that you need a different tool for each diameter cylinder bore you work with.
