You make us filipinos proud and this will explain why there are thousands of filipino seafarers all over the world. They are dedicated, smart, experienced and knowledgable just like you Chief. Keep it up! Salamat!

I've worked on the ship (deck dept.) for quite long enough and still knew little about the principles and functions of some machineries onboard. Well this one adds to my "now i know" list. Salamat chief!
Very professionally presented with top notch graphics and narrative. I must admit that is exactly what I have come to expect and why I continue my viewing. Thanks.
GW That depends on the amount of money the owner wanted to spend on his newly ordered ship. The best material for the piping is Cunifer 10. When correctly designed in combination with a short piece of galvanized pipe (including a spare one on board) this material is troublefree. A galvanized system will start giving problems after being for about 7 years in service. The pumps however need a lot of maintenance on wear rings and impellers
@@scottwhitley3392 Plate cooler plates are almost always made of titanium, they're very thin and individually very light and are super good at transferring heat while being virtually corrosion free, the only fouling we get is from sea life that accrues on the seawater side. Even then it's a simple job to open up the plate cooler and scrub the accretion off with a bristle brush and an HP hose. They are also regularly backflushed which as it suggests reverses the flow of water while the fresh water supply is isolated and carries a lot of crud overboard. SW pipework is indeed just steel but there's really not a lot of it, as Chief Makoi stated, it only goes from suction inlet to cooler then overboard and it's becoming more common now to have the internal surface coated in a resin and there is also of course plenty of cathodic protection.
Sir Makoi.. maraming salamat po sa mga videos nyo po na may matututunan kaming mga future marine engineers.. sana po marami pa po kayong mga topics na pwedeng ma i share po saamin..Godbless you po Chief !! Keep safe po palagi 💯💯
Love the series. I'm a 1st year engine cadet, due to go to sea for the first time in June (hope I get to go and this coronavirus doesn't mess it up for me). Your videos are excellent in helping me prepare for my upcoming exam. Thanks for all you do on your channel.
Good luck to you. So glad to see you have found a directiion to go and commited to it. With all the pc, social noise that goes on these days its hard for younger people to point their compass in a direction their commited to. A life at see is a fulfilling existance. All the best to you.
@@joe18425 thanks, I'm looking forward to going on board for the first time whenever that may be. My college has been shut due to this virus and the college is now in discussion with the MCA about our exams and sea time so hopefully they can work something out to get us away.
Hey Chief, really enjoy your videos. Worked in the boating industry during college for about 10 1/2 years at a boat builder & distributor. They also were a navy contractor, so got to see that side as well. My dad fished in the commercial tuna fleet after WW2 and went to school for his masters papers and navigation certs. So got some training there. He rose to co-captain, and worked in the fleet from 1946 through 1955 just before the seiners became dominant. I also like the fact that you go back to the Maritime Academy as a teaching instructor and mentor the future maritime seaman. Thank you Chief Makoi.
Good Day, Sir. I'm a newbie here and also in Maritime career. An Aspiring Marine Engineer in the near Future and your videos Study Call has great impact for me to know more and hoping to apply it when my day comes. I hope you also have a Videos soon for Principles of Auxiliary Machineries onboard like Marine Pumps and Purifiers. This kind of Videos really helping us, As a beginner on our field. God bless you more, Sir.
Sir, My suggest topic for your next vlog is all about the connection of steering wheel and telegraph to the engine and how it works . Because many of us /maritime students are confused about that . Just to easily understand that thing through your explanation sir . Thanks a lot sir 😊
Thermal engineer here, you do a good job of describing things and how these systems work. One small quib is that these coolers operate on the principles of convection not conduction.
@@ChiefMAKOi I can't beleive you actually replied! I love watching your videos to see how these massive ships work. I am curious as to how shipping HVAC and plumbing works as well. I design systems for buildings and I assume there are similarities and differences in how ships work
@@ChiefMAKOi it's a wonderful resource to use. I will be looking out for those as there are many options and I love seeing different uses of the same science Thank you.
Hi chief makoi, first of all i have to say that i am very grateful with your material about the life at sea, and of course with all the videos about the machinery and systems that a ship employs, i am a four year engine cadet(the most difficult year in My career but i want to cope with this last level) and of course in the future i would like to be a chief engineer as you sir, if you could make a vídeo about fuel injectors or the most common maintenance in the Main engine or in the diesel generators aboard i will to appreciate it , You have a faithful follower here in México sir Greetings
Very well explained Chief! You achieved simplicity while still being exquisitely precise and accurate. And while I would enjoy an hour long walk through of a ship just showing these systems, this is great as a primer for normal people lol
I was on a cruise ship over Christmas... it's two main swimming pools were filled with seawater and these were re-filled each morning. In the cases of cruise ships with swimming pools is any of the heat from the engineering equipment captured to heat the pools? Another interesting heating/cooling piece of info I find really neat... my city (Christchurch, New Zealand) is still recovering from a major earthquake in 2011. We are now building a new large public swimming pool / sports complex. The main pool is being heated, in part, by a heat exchange system from a very large main urban sewer pipeline! It's the first of its kind here in New Zealand. About a third of the city's sewage flows through the "Southern Relief" sewer pipe and the heat from this pipe is being exchanged/used to help heat the new pool complex!
Nice video. Short and comprehensive. You should have mentioned the use of strainers and of the main sea duct or crossover. At least to offer a usual arrangement perspective. Well maybe another episode where you can explain high and low sea chests and ballasting deballasting. Keep them coming Chief! Rgds
This was absolute fascinating. One thing comes to mind. Ocean water is heavy in nano and micro organisms that scale up in engines, heat ex-changers and piping. How often and how do you clean scale within these systems/components and how must manpower does it take? Or do you have some sort of scale control chemical or system to stop scale even forming/building up?
Hello Chief, how about a class on paralleling generator sets? I know there are auto syncs out there, but on our old diesel electric dredge we still have to manually punch them in. Maybe explain how the lights and the arrow actually work when in sync? I am an up and coming young Chief Engineer on US Western Rivers. What you and fellow blue water engineers do is amazing. Thanks Chief.
Really enjoy watching ur vids, i just come across 1 of them by browsing thru youtube and now busy watching all ur vids. Tnkx for the good vids man, keep them comming. And safe sailing.
thank you Chief. I wonder if modern sailors still learn much about and use small rope much? I mean small ropes, Like 1 inch to around 5 inches. When I was small my Uncle , a life long sailor used to bring me wonderful dogs, cats etc he made with just his hands then presented them to me. You can imagine a little kids joy. Time has taken them from me but not my warm memories....Thank you I'm a 66yr old Aussie man who visited Philippines for holidays many times, Nice country, Nice people.
Hi Chief Macoi I learn a lot from your video...I will share it to my students.. I hope your next video is the operation of a camless Diesel engine... Thank u
Really liking the format for these types of videos, short and to the point. Couple of ideas - Traditional/electrically-controlled fuel injection, and self-cleaning HFO/LO purifiers and their principles of operation/troubleshooting.
Chief, good job explaining the heat exchanger system, looking forward to the next on the internal FWC system. Good news is that I plan to incorporate your videos in my high school physics class thermodynamics unit. Keep it up!
This video made a lot of things connect in my head. Unfortunately my understanding oh how an engine the size of a house is cooled, was found lacking. Thanks for filling in the gaps! Im also really enjoying the rising production quality. Nice editing , effects etc.
Chief, is it possible to analyze the cargo doors that been used for helipads and their strength? Are all the same or the designated for helipad is strengthened more? Thank you
How much of a shop does a ship have? do you have a lathe, a magnetic base drill press with reverse for tapping and the ability to tig aluminum? Or is it more like a bucket of dull cheap and bent vice grips. Do you supply your own hand tools? If you weld in heavy seas, can you see it in the finished bead?
A lathe machine, drill press, electric arc and oxy-acetylene gas is standard for ship's workshops. Pkus an assortment of different hand tools and power tools as well. Pretty decent. We don't work with aluminum that much so nothing for that.
That was a very informative tutorial and you presented it really well. Thanks for sharing your knowledge on this subject as I had wondered how the engines were cooled.

Enjoy all of the Chief's videos. The technical information is very interesting.
Corrosion must be a big headache when it comes to maintaining this system. Great video as always.
GW sacrificial anodes are used in coolers to help prevent corrosion
Erotikstudio Winkler GmbH The plates on a plate cooler maybe made out of stainless steel, but the actual piping for the sea water system is just steel
On the Mississippi River we have issues with what we call zebra muscles. Ugh they clog up the tubes and we are constantly cleaning them.

Best 6 mins about sw cooling, I've ever heard.
Salamat po ulit chief makoi, since wiper position napo yung sunod na sampa, dagdag kaalaman po ito para sakin! 🙏
Clearly mentioning what causes a problem, what the problem actually is, and what we can do about it :) I love the way he teaches!
I’m a marine navigation student but the wording was so simple that i was easily able to understand everything! Looking forward for the next one
Great job Chief

We'll get to that topic eventually but it's pretty much the same except that the coolant for the condensers will be (eventually) sea water.

Love this episode. More videos like this Chief.
Excellent video Chief!
Very good explanation of the seawater cooling system👌👍
Thanks dito chief.for advance study purpose to para saakin
Thank you for these topics and this format. It is fantastic for those of us who want more technical details. Great job, S
Very well explained Chief!

very imformative sir
Such a jump in production quality! Appreciate it man, must’ve taken a lot of effort
Love these videos, so very clearly explained. A very accomplished engineer indeed. Great stuff.
I am very surprised to know na may mga shell and tube heat exchangers din pala sa barko. Yan ang favorite topic ko sa chemical engineering :)
This series is perfect since I'm an Oiler and getting enough seatime to challenge the 4th Engineer exam.
good luck

Can you make one on purifiers, actually working of gravity disk is not going in my head.
Nice one sir
Very good video..I suggest you to add more subtitles for this series..im about to start as an engine cadet in couple months and I can't wait!
very well explained. very well indeed. I am a ship agent from Brazilian ports. congrats bro!
Very nicely explained chief.... Waiting for other systems too
Thanks chief, I learned again. Good day !!!
I wish i could see this video when i was a cadet ! Thank you anyway ! Waiting for more videos from you Chief 🙃
Fresh water system please.... great video btw
