I continue to be amazed at the depth of maintenance performed at sea! I'm understanding more as to why there must be redundancy with systems. A ship is it's own self-sustaining island. A realization to folks like myself who've not been in the bowels of a ship subjected to the mechanical aspects. Sure I think, there are engines, generators, water makers, and other pieces that keep everything going... I just never realized the immense responsibility of care and knowledge that goes into the upkeep! Thanks for another great video! Stay well, stay safe!
I'm thinking the same thing. I expect to see work like this done at dry dock. I don't know what these guys get paid but I have a feeling that it's far lower than should be given their expertise.
Retired heavy equipment mechanic here. I used to work in remote camps, I totally understand the concept of not just picking up a phone and getting parts. Love these type of videos. Your crew seems to work well together.
Very nice Chief. As a heavy truck mechanic all of the things are very similar. It's interesting that you guys don't use digital Verner's it's something alot of people can't do the greatest me included. I also like the point where you talked about improvising because it's so true and finally about stuff not in the manual. I heard a saying way back when that " Every five minute job is one broken bolt away from a three day job. As always very nice Chief! Take care and stay safe. And dry!!
You get an extra digit of precision with vernier over digital. One more then the specs they give you so you can make a more informed decision. But for a fast turnaround shop it's probably not worth it to spend the extra time decoding those for every mesurement.
@@nick4506 I have no idea what brand calipers you are using, but on my Mitutoyo's it's the other way around. The verniers have a resolution of .001" and digitals have a resolution of .0005". More importantly, neither have the precision for this type of measuring: It should be done with micrometers.
Note that at sea if there is a breakdown you can’t safely pull over to the shoulder, make a phone call and expect help in a couple of hours. They are overhauling the backup generator that is the backup to the running generator.
The British Motor Corperation (Red Ken shop steward fu*ked the Chieftain tank engine). They should have been castrated. So many had been butchered on assembly. Every single engine we had to strip and rebuild and what they had done was appaling. Not exactly nice to know you have the same problem across the pond as you say.
As a mechanic I have rebuild several engines from simple 2 stroke to motor cars. So watching this and just seeing these marine diesels is just fascinating. The size of the parts is just amazing but the skills are the same! You're team is awesome and thanks for the insights of life on the oceans
Thanks For Sharing Great Videos Ship Engine Overhaul GE on Bulk Carrier Ship.. Bon Voyage n Safe Sailing Chief n all crews. Greetings from Seaman life at Bulk Carrier DL Acacia Panama
Again I am fascinated by your indepth and informative aspects of life at sea , keep up your excellent work chief love and best wishes to you and your family Michael Edinburgh Scotland 🏴
We usually apply grease around the cylinder head where we remove the Valve seat via welding, it helps preventing flux from the weld spark from sticking into unwanted areas
Thanks again Chief, once again you have answered all my questions. As a retired mechanic [gas and diesel] I really enjoy watching techs who know what they are doing. That little trick of using cloth to remove piston rings was a good one, really saves wear and tear on the fingers. Looking forward to the next episode.
Just goes to show, Preventative maintenance saves a lot of time,money and headaches. As both of my grandpas have told me as one is a Aircraft Mechanic and the other is a Machinist that makes tools and dyes. And I myself I’m a truck driver.
The small screw that just refuses to turn and the tool that just refuses to work are found in all occupations. The manufacturer/designer of the part and tools seem to have set this up to add a bit of exciting variety into our difficult but mundane lives. Thank you Murphy. Go Figure.
@@kennyc587 ...and lowered the production volume of good "easy out" kits. Most of the time, my "easy out" kit consisted of a steel hammer, a cold chisel and....the all required few, if not many, choice words.
Where I retired from, we had four 4.4kw 12 cylinders emergency diesel generators. I worked in operations and would remove the generators from service and remove the fluids. Then we would turn it over to the mechanics and get out of their way. I would get to see the various stages of the teardown and the rebuilt but was never actually able to see what it takes to do the complete job. I enjoy all your videos.
The fact that this Video Makes You Want to Watch it Again ,And design of Sploot, it's Just Too Perfect , Hard to stop watching And I don't know exactly Why..
I always liked how the Himsen's were to work on. Very simple, easy to access most things, and I always thought they had a logical build to them. The H32/40's had a little bit of weirdness (HP fuel pipe into the side of the injector) but not too much. Love the videos!
Enjoy the vids chief - I was the manager if a small diesel power station for 34 years looking after 7 generators and all the usual auxilliary plant, however I trained as a marine engineer initially.
In the deep past for me, a friend was Chief Engineer on an Australian-registered cargo ship. Yes, a while ago! He described similar maintenance regimes. I served in the Australian Navy as a deck officer, but one of my (small) ships had a complete engine change, unbolt the soft patch and lift out and in, then measure EVERYRHING nd adjust before we poured the seating compound around the engine seats. I still remember the engineers "measuring three times", etc.
Great video once again chief. As a retired mechanical engineer working on large earth moving equipment. It's great to watch skilled engineers. Brings back great memories.
The procedure is exactly the same when writing diesel mechanic trade test like taking measurement etc here in South Africa i love your video Chief i hope one day i will meet you f2f
Another great video, brings back memories for me from many years ago,and good to see not much has changed in the methods and practices, keep the good work up,can't wait to see the rebuild and start up.
No, it's good. Leftover pieces, it's been found, have been secretly put inside the engine by manufacturers as head scratchers for mechanics. Keep them on their toes and adds needed excitement to their otherwise mundane and boring lives. 😁 Collect enough pieces and you can make an attractive wall clock, or unique paperweight....you know..
Another great video chief..one bulk carrier I was on had a steam generator..when vessel under navigation they would use steam generator and stop diesel generators..steam came from economiser. A ferry I was on during drydock in Curacao we scrapped down a generator to the bedplate to replace the crankshaft..
Dear Chief, I wanted to tell that, cover nuts or con rod nuts are not tigtened by hydraulic force, but the bolt is tensioned-lengthened so a person can even hand tighten or lets say tighten the nuts to 25 to 40 Nm. There is really "Hydraulic Tightening" but this to apply really big amount of torque like 1000 Nm or more. Anyway, great video, sure that it will be appreciated by many engineers. It is a great service for the one who want to learn. Thanks!
Chief, I have been out of the Ships Engineer Officer game for over 35 years now. Do I miss it?? That is a BIG no !!! Your videos are always great ! They remind me of a different life. Thanks again. Sincerely, Rod
I like chunks of nice shiny metal 😋 . I liked the piston rod. I drooled over it. Does anyone else like the aesthetics of such things ? Am I weird or what ?
Fascinating seeing some of the differences between that, and like a semi truck rebuild, or a V8 gas engine. I’ve had to personally rebuild a few of my engines over the years. It’s both tough, but fun.
I’m fascinated that every wear item is independently replaceable - guides, seats, liners, etc…. It’s like it was made to be worked on and reconditioned, not discarded like consumer grade garbage. 😁👍🏻
I am a graduate of criminology but i always watched your video the moment you upload it. I always pretend that someday work on board a ship but unfortunately it was not happen anymore.
Watching this engine being stripped down takes me back fifty years to when I was serving my apprenticeship on Birish Railways deisel locomotives. My first job, after a years full time at college, was to grind in by hand all sixty four inlet and outlet vales on a Paxman V16 loco engine.
Thanks Chief. I always look forward to your videos as they give me a glimpse of a life I'd otherwise never experience. I'm surprised the compression ration is only 15:1, but I guess it is never started in extreme cold and, when running ,the turbocharger increases the dynamic compression ratio to a higher value.
Time to show the tools some care, and remove those burrs on the drifts, before they turn into shrapnel. However that engine looks really clean for something that has run 25k hours, or at least 3 years since last overhaul, though with three likely nearly 8 years of use, yet it looks so clean. Testament to the crew to keep the engine looking so good.
Very informative video . I hope you will continue doing with your best comments . Fine job . It’s really interesting to watch . Do it again 3/4/5 day and so on
Chief Makoi commented the Generator Overhaul was usually at 20K Operating Hours. By Comparison, General Aviation , Gas Engines, Seldom go over 2,000 Hours before an overhaul. Different engines but stark by comparison. Thanks for the Rebuild Series Chief, Nicely Done.
@@nmccw3245 There's actually quite a difference in maintenance in aircraft engines. A Kinner radial is almost a train motor and similar looking flat Continentals can range from 1500 to 5000 hours. Crankcases often suffer.
Good day to you Chief and your crew. I'm always just fastenated with all the little parts and pieces of an engine. It's amazing how all these parts come together and make an engine work. What you call a 'valve spindle,' we call the 'valve stem.' But I'm sure the results are the same! Is 20,000 hours a lot of time at sea? Most of the time, your trips between ports may daye days, or even weeks at sea! Seems like 20K of time would get eaten up pretty quickly to me. Looking forward to the completion of this maintenance operation. Best to you and the crew...
as always, fantastic video, thanks! *respect* to you for your deeply competent diligence. i wonder how often you detect falsified maintenance records? seems like there'd be a lot of shipping companies that would skimp on required maintenance, especially with lax enforcement oversight, as is generally the case these days. :(
