- This video shows how to start-up and secure a ship's Fresh Water Generator. Most cargo ships are equipped with a Distillation Plant. This is how ships convert sea water into fresh water.
Yesterday my frnd teach me easy now I watch your video it's will be easily memorise and understand ❤
Here's another technical video for all of you. I hope you guys enjoy!

I served onboard the U.S.S. Cushing (DD-985) in the 80s in Auxiliary Division, our main job underway was to operate the evaporators. Brings back good memories, thanks Chief! 😁👍👍
Dear Mr West,
I just watched a video on the U.S.S Cushing DD-985 being used as target with different types of missiles and torpedoes .
She took a lot to sink her .
It must break your heart to see a beautiful ship like her at the end of her life being sent 15,000 feet to the bottom of the ocean...
Take care.
@@charliepearce8767 She served right to the end. The last of the Spruance class to be decommissioned.
A Gang, Evap Watch?
(6:15) No need to study thermodynamics to understand the phase diagram of water ;) :)
@@richarderion4611 Yup
Thanks for another peak behind the curtain. And distilling it down for us.
Perfect explanation with step by step exhibition
I really enjoyed every Chief Makoi's video, it was very fascinating to learn about ship machineries. I was passionate to learn more about Marine Engineering. Hoping to become a Chief someday. Godbless Chief Mark.
Your knowledge is amazing. Your willingness to share it is wonderful. Thank you for sharing.
Keep safe always sir and the crew!😇🙏
I always appreciate people like you chief, even at the top still shares knowledge for other people. As an engine cadet I find it very helpful with actual demonstration, since I'm reading manuals and still get confused. Thank you and keep uploading for more, Godspeed!
This your comment is exactly what I’m passing through at the moment, now in bulk carrier in shipyard.
4/11/22; ..thanks Chief for video on making fresh water from salty, sea water. That is a whole lot of steps, valves, gage readings, walking to different areas around big tanks & distractions which must you & yur mates must absolutely master. Again, much appreciate you showing all us armchair YT viewers just exactly goes on inside these big ocean going ships. Amazing the complexity that has been matured into the different categories for successful ocean going vessels to navigate & perform all aspects of machinery manipulation for safe voyage for crew & cargo. Always impressed with your videos, content & editing. Stay safe Chief, keep your videos comming!🛳⛴🚢👍👍👍🧑🔧
As usual well presented and explained, thank you chief another story well done 👏
Great Video! I like the combination of animation and diagrams along with real life operation of the equipment. Thank You!
I was on the USS Bremerton (SSN-698), we had a 12k gal/day steam evaporator and a 2k gal/day electric evaporator. We still didn’t have enough water to take “Hollywood” showers.
That was almost like being in class again. I had to learn this for water systems management but never got to use it in a real life situation. It brought back some knowledge that was stuck way back in my archives.
Excellent video as always Chief! Thank you!
Good day Chief Macoy thanks for sharing very helpful for as kapatid sa hanap buhay. Keep safe Chief and more power to you and company, God Bless us
Hi from uk Chief MAKOi and crew👋👍 great to see this procedure in detail👌 its good to see how the energy is spent in many ways to aid the ship and crews life 👍 thanks for this and thank you for your time be safe and see you soon👍👋
Loving these more technical videos! It's cool to see how the "principle of operation" diagrams are implemented with real parts
We called it a fresh water 'Evap system.'
I guess it functioned in a similar way as your system.
And MAN! Were they strict on how much water you got to use!
Those showers were a luxury, and they were limited to 5 minutes usually.
But shipboard water was way better than water we got in port to drink.
It seemed we always had a big rush to the head, when we drank water from port. Water was often delivered to our ship in potable water barges.
And you could never be sure those floating water tanks were clean inside. Or that the hoses it was pumped through were clean. Or that the water itself, was clean.
Our ship's doctor would test the water for it's cleanliness... Declare it good... Then we all paid the price with plenty of toilet paper!
Oh yes! Those were the days! LOL
Feels like I’m ready to be a ship engineer by watching your videos 😂
Malaking tulong at dagdag kaalaman talaga mga videos mo sir. Thankyou sir
I saild till 85 on the Atlantic. This gives so many good memories. I am glad I did it
hello I'm really impressed about your ship content and also starting to really like them now.so keep on spreading and showing how awesome and amazing these giant boats truly is✌
i think its not aboat its ship but how am i?

Good Day! Very much enjoying your series - learning very much with your added experience and points of view are an added bonus - let me know if you get shore leave in Kalama ,WA the next time - lunch is on me!
Bless you for the clarity you give in the areas of your teaching.
we allway waiting for your neww videos god bless you for you efforts and cantinue
Great explanation with visuals . Cheers
I appreciate the transition you did by pressing your camera into your colleague.
Another Gold production from Chief Makoi.
Thank you you.
Its makes me feel at home in a Plant Room looking at all the pumps and valves with the constant high pitch reves of the motors in the background.
Hi sir, iam an Indian I saw your videos youtube channel,I learnt most valuable things your videos and apply for my job. Thank you sir.
As always really good and quality high content. You are an inspiring teacher Sir.
Thank you
This was very interesting! I always wondered what the process was for purified water on a ship was and this answered my questions. Thanks for sharing this.
God bless you! Thank you Chief !
Thank you, Chief as always your way of explaining is good one has to dummy not to understand. May God rewards you for all these efforts. I'm sure some young men could get a lot of benefits out of your hard work. Thank you again.
Excellent discourse on distillation of sea water to potable water.
Thanks for sharing.
Thank You for sharing @Chief Makoi, i am one of Your old viewers, Just love Your channel, i live near the Port city of Durban here in south africa, we had some of our worse floods ever, Even some shipping containers washed away in the floods, if You type in Durban floods on You tube, You wil see some footage!
Love the way you explain these tech installations, easy to understand !
Thanks chief ;-))

I love all your Videos!! Excellent job.. your hard work doesn't go unnoticed.
This was one of your most interesting videos. Thank you
Pure Knowledge.. Wonderful insight Chief :D
Thanks so much sir.. this type of video help us to much
Great job! Your videos are very good!
I've been told "the age of sail" is an epoch the human race has left behind. Yet the seas of the world are the only thing, on this planet, that can truly handle the tonnage of our global economy.
Another great video 👍
Awesome video thanks for sharing🌊
Superb video ..superb explanations..👍👍
I ENJOY ALL YOUR VIDEOS CHIEFF,,FASCINATING STUFF FOR THIS LAND LOVER..STAY AWESOME!
Very interesting Chief!
Laking tulong neto sa pagka kadete ko sir chief🫶. Salamat po!
Thanks Chief!
Always informative.
damn i did not realize they use waste heat from the main engine to distill the water :D i thought RO was the way to go but this makes so much sense :D
This video helps alot salamat malaking tulong to samin na galing sa domestic inter island na nganagarap mkasampa ng international
i really enjoy your videos please make more like that!!!!
Nice. I now understand how vacuum distillation work. Low temperature energy can still be used to produce useful work.
Very interesting. I always wondered how that worked. Thank you.
A fascinating explanation. Deep water turning on and off, does that infer starts and stops beyond the continental shelf ? 20 tons production a day infers about 4800 US gallons per day. A gallon of water weighs 8.3 pounds. The average household consumes about 87 gallons per day, so approximately 55 homes per unit. Being a little crazy with some math... there are approximately 170,800 homes in Tampa Florida [numbers vary a bit depending on sources]. That would require approximately 3,100 your ship sized desalination units to supply it water from the sea, assuming my math is correct. I love your stories. thank you for doing them !
No one outside america can understand what your trying to say
A project that size would be awesome but I imagine the chemical treatment bill might be a lot. Along with whatever kind of energy source you use to run the machinery. I think I like what you're thinking though.
You are assuming the tonnage is US or Short tons?
I assumed one ton equals 2,000 pounds. 4800 gallons equals 18,168 litres, 87 gallons equals 329 litres. Close enough. 3.785 litres per US gallon. I am aware the marine environment uses 2240 pounds per ton. I am not aware of the pound holding different values around the world, I am aware both tons, and gallons vary. I was attempting to grasp a data point on the magnitude of the seawater desalination problem for terrestrial use.
There is a company called Miox that has produced portable water sterilization liquid from a small hand held device originally developed for the military but also sold on the open market to campers and hikers.
They also make municipal sized equipment for water treatment plants and are sized to plant production. The equipment consists of a treatment chamber with a replaceable platinum element and a DC power supply. The equipment will dose a predetermined amount of ordinary salt into the chamber as well as a measured amount of water. After the DC current is placed between the chamber and element after a controlled amount of time the net result is a liquid similar to chlorine which is dosed into the water supply. The net result is the use of cheap table grade salt and water. No caustic chemicals need be stored on site.
Equipment has a high initial cost but users win because it uses cheap salt as its "chemical".
Sea water to fresh water. A simple concept, but very complex in actual operation👍.
It always amazes me how many steps have to be made manually to operate such a simple system.
One would think that there is a automated system to do it for you.
I think there might be some practical reasons for this. My thought is either to make it easier for people to learn, due to many ships employing people from third world nations who might not have the same opportunity to learn automated systems, or manual operation in case of faults at sea (power outages, bugs and such). Also, any sort of sea air and water hates electronics that overstay it's welcome.
Of course, this should be possible to automate despite these issues, but I believe it's safer to have a pair of human eyes on these. 😄
the only thing automated is good for is tripping constantly and needing someone to constantly watch it more than a manual system. automation just for sake of sales is the worst garbage
The parts that make sense to automate already are (salinity sensor). Imagine having to manually test for salinity.
For the rest of it, I imagine the additional machinery to automate valve operation would be needlessly complex and would make maintenance way more difficult. These components need to be inspected and maintained regularly as is, adding more possible points of failure in the messy environment of a ship is probably going to give low returns.
But the tech will probably just get cheaper and more reliable in the future. So who knows, maybe future ships will have smaller desalination systems that are more efficient and can be more easily automated.
The valve path is crucial in many systems.
Would you trust your drinking water, hundreds of miles from anything, to you "smart"phone or PC?
Just think of how many times they let you down.
It's interesting, that the whole procedure consists of only opening and closing valves in the correct order. In theory, this could have been done in the 19th century! And actually pretty smart to use the combination of free heat and a vacuum to minimize energy consumption.
Good point, the only bits they didn't have then was the salinity meter and probe,although I'm sure some clever folk would be able to measure the salinity in some way. Water treatment chemicals may have been a bit suspect though.
@@daic7274 They had hydrometer to measure density of fluids like water, beer or whine 😀. Just get a sample in a bucket, put the hydrometer in and read the scale. If they would have added some minerals, this should be safe to drink.
They actually did. There were fresh water generators in widespread use by 1865 for steam ships. Certainly not this advanced though,
Multiple-effect distillation has been used on ships since the mid to late 1800s.
(6:15) No need to study thermodynamics to understand the phase diagram of water ;) :)
Love the content..
good vid chief
Oh man using excess heat from your jacket line and a small pressure reduction to boil water is genius!
If I read the guage correctly, the pressure reduction is substantial. Looked to be about 95%. Atmospheric pressure at sea level is a tad over 100k pascals and the gauge showed almost 0.1 m pascals. Or do I have the units wrong from the gauge face wrong?
Thank you Chief
All ours tugs have them and sanitation lights in line, nice post chief.
This was very useful. I just bought a cargo ship, and the instruction manual had nothing about how to make fresh water.
Nice info sir. SUggest next video medical emergency procedures for cargo/bulk ships.
Wow! I thought the process would be computer controlled but no, somebody open and close all the valves and checks all the gauges.
Thanks for the explanations, Chief...
I remember sitting and running the fresh water maker "The Vap as we called it".
Awesome! 👌👌👌
I would work for you any time chief. You run a clean and safe ship.
I worked field service for Aqua-Chem in the 70's. Repaired a few of these on ships and oil rigs.
Very interesting, thank you. A basic and robust system. Good use of the ejector pump for vacuum distillation, was wondering how the vacuum would be achieved when you mentioned the engine water temperature. The salinity meter also turns the system into a basic reflux still :) nice setup.
practical answers too practical questions which apply to many other practical applications and explanations. a virtuous cycle.
Thank-you for posting , all fascinating, how things operate on cargo vesicles
good explanation . Godbless
reading your replies... generating 20 tons per day, with storage up to 200 tons... i thought why would you need that much?... i guess its more for the cleaning of the cargo holds, and the pressure would also help on that... and probably also use for emergencies like hosing down pirates
I would think sea water (or even better, the increased salt content residual water from the FWG) would be good enough for pirates. Why be nice to them?
Chip, sana next topic naman natin ay yung basic kung paano sumukat ng guages at trabaho ng cadet na newly grad, sana po ay manotice nyo. Godbless and sana madami pa kayong maturuang gusto maging marino🙏💯💯
I think the closest I've ever been to being on a ship was when I've gone canoeing, kayaking or paddle boating. Still love watching these videos, though!
Thanks very much sir
Interesting enough this is the same method used to make WFI ( water for injection) for IV bags. Initial water is soft water though. Thank you for sharing.
Chief can you more technical into marine engines and explain concepts like 1) EARLY INJECTION, 2) DELAYED INJECTION , 3) FUEL PUMPS AND 4) FUEL INJECTORS.
Love your work!
Idea for next docu: start with an overview of the process with the 2d and 3d animation you used. for a sience or engeneering noob this helps a lot with the understanding of the whole machine.
then show in detail how the machines work in real life, maybe with you in the shot? what do you think? a bit like SmarterEvreyDay...
The complexity of a ships engine room is much higher than I imagined . Does the condenser ever get a calcium build up like a kettle ? I jest but a few gallons of best vinegar would do the trick.
Hello Chief I’ve been watching your videos and I’m learning a lot can please do a video about the oily water separator
Nice presentation Sir. Can you please try to include opening up and boxing up of FWG in one of your future videos....it would be really helpful for reference...
Great detailed explanation. What is the daily capacity of your plant? Back when we had steam distilling plants on submarines the plant was several thousand gallons per day for a crew of about 100 on a nuclear ship. There was also an emergency electric distilling plant of 1600 GPD.
20 tons/day.
Running the numbers shows around 200 gallons per hour.
Considering the fact the the pressure on the gauge was in MPa, his answer is probably in metric tons, but there are multiple types of tons... Short tons (2000 lbs)... Long (or "Imperial") tons (2240 lbs)... Metric tons (1000 kg or 2204.623 lbs)... 1 US gallon of water weighs about 8.34 lbs... So, 20 * 2204.623 / 8.34 = 5286.86570743 gallons per day or 220.286071143 gallons per hour...

@1:56 chief shows off his CGI skills.
So vacuum is the trick. Learn something new everyday.
Thanks chief . Make vedio on OWS how to operate
Chief, another super interesting and practical video taking your already good classroom explanation to a real life implementation. Please keep doing these types of vids.
I do have a question: Do the techs ( mates?) follow a procedure checklist of any sort? It seems that there are a number of steps and valves and controls are located all around so it could be easy enough to perhaps skip something if distracted etc.? Have you read the book “Checklist manifesto”? If not, it’s a short read and just so very eye opening!
Stay awesome and safe!
plant manuals contain pocedures followed. most of times muscle memory kick in for principles are the same. its wise to ask old crew about placement of valves otherwise one has to visually trace piping lines and valves according to piping diagram
This is a single stage (effect) evaporator. It is low efficiency but the heat is free and there is plenty of for a ship with 18-24 crew.
Ships making water from steam has to pay for the fuel to make the steam so they have multi effect distillers, more efficient in water production per pound of fuel used.
The most common evaporators are Nirex brand using plate heat exchangers instead of the shell and tube one in this off brand unit.
One more thing for the ex Navy MM’s reading this.
All those hours standing Evap watch was a waste of time!
I got out of the Navy and went into the US merchant marine with the steam tankers and container ships. We had Evaps from the same companies as the Navy ships, multi effect
Flash units, and Never had a watch stander on them. Aqua chem was one maker.
You started it and after stable you walked away checking on it once an hour on a normal round.
If it was not stable you fixed it not have a guy adjust it continually for 4 hours.
I was watching a curiosity stream show called engineering the future Episode 5 Called "Maritime". they discuss the use of wind power on modern vessels as a way to save fuel costs and such. I would be highly interested in your take on that. One of the ships they show was a bulker carrier vessel. The one deployed seems to have the "Sails" on rails mounted along with the ship that could be moved for loading and unloading.
Very interesting. I saw the place that said makes 20 tons/day. How big is the water storage tanks, and what is your ships water consumption numbers?
Great vlog as always! To me this is moy complicado. Lol! How often do you do this? Fresh water is used for cooking, cleaning, washing and drinking. I hope you have had a safe easter together with your family. That was a huge storm. Be safe!
