I have just found your channel. How great of you to show us inside these large ship electrical systems. My experience as a marine electrician has taught me many things over the years, I've wired several new docking tugs, but never seen inside the ships my tugs dock. Thank you for making this channel! I look forward to learning what goes on inside these massive ships!
On a much smaller scale, I experience the same with vehicles as intermittent shorting/misfiring. It is usually a wire that has been nicked or otherwise a small wear from vibration. Good video. Thank you for posting.
Simple damage but if u are inexperienced to do it, its not that easy even worse u disembark. Thank you for ur great video elec. God bless. Aspiring to be one. Hehe.
Very interesting video. However it requires decipline to follow a proper troubleshooting process. Sometimes, it might be even annoying to start looking for some. Thank you for the video.
Thats a good practice...better investigate 1st the wirings....minsan mag fault then mawala...mahirap din minsan mag trace...the exact location...buti yan kita agad sa loob ng panel box..good job
Hello Chief Lecky, Good Day sir, can you teach us about the basic marine automation onboard such as PLC, DCS and SCADA sir so that we can have good knowledge about this sir, thank you sir. God Bless
Ground is frequently used in American English, whereas the rest of the world tends to use Earth. Both tend to refer to the same thing electrically (although some may argue some very subtle differences).
Hi my friend Leckyjake, I'm speaking from Brazil, I'm trying to find out about the Alj281 from the Daikin container.. Other than the SMV valve, the SMV coil, and the solenoid coils, what else can cause this alarm?
Hello sir can you please suggest book for power system protection and switch gear subject, how did you learn how to read single line diagrams, and how to locate and calculate fault current and implementation of appropriate protection scheme 🙏🙏🙏🙏
Railroad locomotives often get sidelined for ground faults for the same exact reason : chafed wires shorted to the metal frame Once, a guy out in California was able to buy an entire GP9 locomotive for about $10,000 because the railroad sidelined it due to ground faults and sold it for scrap ... but he knew of these kinds of faults and rescued it. It runs to this day on the Niles Canyon Museum Railroad. Moral : check your wires, always check your wires. Contact with metal, too tight of wire ties at bend points, etc etc. You'll either chafe and short to earth/ground, or you'll snap from repeated bending stress and end up with a discontinuity.
The repair was enough to get them to port where the engine can be shut down and the harness repaired. Can't isolate that panel since both the redundant systems run through it, without shutting engine down-and that doesn't get done except in emergency.
Good morning sir leckyjake. BSEE student po ako at graduating na po. after po mag board exam nagbabalak po ako maging katulad nyo po na eto. bale naaral ko na po mga dapat ko gawin para maging eto. tanong ko lang po ano po ang mga training or tesda courses na dapat kong pasukin para po ngayon palang magkaron na ako ng knowledge sa pag troubleshoot ng ibat ibang machines na ginagamit sa barko. maraming salamat po
Good day sir lecky, since we have redundant system for Engine Control System i.e., ECU-A and ECU-B. The scenario of shutting down ECU-B, will ECU-A takeover and ME-C shall keep on running?
I'm guessing this is just a bigger version of the typical VW multi-ECU system, which is unsurprising, as Volkswagen owns a large part of MAN, and they likely just reused the same tech that they have already developed for their cars. In this system, one ECU controls half the cylinders, and a second one does the other half, with all sub-ECUs being managed by the two main ones over the drivetrain CAN-bus. If one main ECU fails or loses connection the the drivetrain CAN-bus, that half of the engine will shut down, and the other half will go into a reduced power mode (called "limp mode" for road vehicles or "main engine slowdown" for sea vessels), which is meant to somehow get you home, but not for reaching more than walking speed. The same will happen if any critical sub-ECU (such as a turbocharger controller) loses connection, only that all 12 cylinders will run at even lower power levels, as you still have 2 (mostly) functional banks in limp mode, rather than a completely dead one and one in limp mode. This same system was used in almost all VAG vehicles with 10+ cylinders, including the V10/V12 TDI, V10 TFSI, W12, Bentley W12 biturbo and, apparently, MAN container ship engines. I wonder if that thing is also VCDS compatible? I mean it has CAN-bus diagnosis, so hooking up an OBD2 socket would certainly be possible, it just depends on whether they use the same protocol...
Pre planning how far you are going and how long it will take vs the fuel burn rate per hr/day then you add an reserve just incase you need to divert due to weather or other conditions. You would do it similar for a airplane
You have a huge fuel tank, calculate how much fuel you are going to use, then fill it with that amount plus a bit extra in case anything goes wrong and you use a bit more fuel than intended. You can do the same with a car: If you know the average MPG you get in that car, just divide the length of your trip in miles by the MPG, which gives you the amount of fuel in gallons you need in an ideal case. But because you don't want to run out of fuel if the trip is a few miles longer than planned or you get worse MPG than average, you might want to add a bit extra to that. For a car, 3-5 gallons are enough, for a container ship, it is more like 3-5 truckloads.
Informative video. Thanks sir lecky. I'm an ETO Cadet right now and this really helps if I encounter this trouble. Requesting a video also how you met and court your wife rose hehehe. More power to you sir and ma'am rose
You're a sharp engineer Lecky! Keep posting :)
Thank you Lecky for sharing your experience and knowledge. Didn't hear the 12 cylinders engine sound for almost 5years, thank you for bringing it.

Gud day Po sir, salamt Sa video mo, dagdag Po Ng kaalaman Sakin, kc nag aapply din Po ako Sa ngaun.bilang assistance electrician.
instincts i tell u are most imp on this job.. knowledge not enough.. great job lecky.
A very valuable video!!!
Thanks you.
I liked and subscribed! Great video mate. Sometimes earth faults can be very difficult to find, but you found it no problems 👍😁
I would put a piece of insulating rubber mat on the bottom of the box to additionally protect the wiring from rubbing against metal.
Thank you sir the lesson of main engine slow,I hope next lesson of video.
Wow, very informative content sir. Thanks for sharing
The Legend has returned )) Where have you been..???
Great jop from a great electrician , keep up the excellence work . By the way , long time to see you man 😁..

great info thanks dear
Welcome back bro
Welcome back!
we never forget to like your videos my friend :)
make more technical videos
i like the approach you use on technical problems
Thank you Sir!
Finally, i am really waiting your video
Present master!
I have learn a lot thank you Sir
Thank u sir...
Such a simple fix, well found.
Good job
I am also eto . Big fond of u
thank you lecky
🎉🎉🎉
Thank you sir
wow interesting
good day sir lecky jake, hows the grounding system on a ship? how differ from it to the earth ground system on a landbase?
Loving your videos. Just wondering where does your poop go.
❤❤❤❤
Great job as usual. Maybe the word you want to use is "ground" instead of "earth"
I think, it's also correct. I have met only combination of words "earth fault" In the technical manuals
Ground is frequently used in American English, whereas the rest of the world tends to use Earth. Both tend to refer to the same thing electrically (although some may argue some very subtle differences).
@@arpremo agree. In my country we use the word for "earth", but in manuals you will get "ground". Anyway, outstading job in the video.

Hello sir can you please suggest book for power system protection and switch gear subject, how did you learn how to read single line diagrams, and how to locate and calculate fault current and implementation of appropriate protection scheme 🙏🙏🙏🙏
Like the one which can provide easy and simple explanation may be with examples 🙌
Walang ganyan sa MOP namin sir, nakadisable. mahihirapan ata ako sa pag isolate dito.

Thanks
Long time to see u sir, what happen?
Hello leck can you please put videos for troubleshooting in lyngso panels
FIRST👍
How did you repair the actual insulation damage?
The repair was enough to get them to port where the engine can be shut down and the harness repaired. Can't isolate that panel since both the redundant systems run through it, without shutting engine down-and that doesn't get done except in emergency.
@@ConstantlyDamaged Cool, thanks!

Am assistant Eto and I want to learn from you pls... Thank you
What is the rationale behind only using a zip tie instead of also wrapping the nicked wire with electrical tape?
I have this eicu low insulation, but only occur when ship sailing, when engine stop the insulation is gone can you please give me some tips?
Only poor design control system will shutdown single main engine ship. Amateurs in that design office.
I always asking my self, how you have enough fuel for long journey when you don't have gas station in middle of ocean ....
Pre planning how far you are going and how long it will take vs the fuel burn rate per hr/day then you add an reserve just incase you need to divert due to weather or other conditions. You would do it similar for a airplane
You have a huge fuel tank, calculate how much fuel you are going to use, then fill it with that amount plus a bit extra in case anything goes wrong and you use a bit more fuel than intended.

@@unmountablebootvolume now it's have sense
Now fix the fuel pump fault
Where have you been bra?
Lecky how can i contact with u???
Why did u not replace those damaged wires, sir? You just put an insulating tape and a cable tie for it
shutting off breaker or isolate wires related to main engine will cause of shutting down the whole operation.
Never replace a wire on a running system.
It is also in the main engine which is not available for temporary shut down.
@T.J. Kong thank you brother
