As someone who grew up far from to ocean, the idea of 6600v equipment on a ship is a little mind boggling. I realize that heavy equipment needs high voltages, but the idea of multi-thousand volt equipment on a ship is something I never would have thought of. Thanks for the video!
There's probably more and longer wiring in these large ships than in an entire town. And, all specialized uses. Long runs + high voltage == lower current. Well presented docuentary of this project... change those dampers 👍
@@roetemeteor 6600 will be the main bus fed from the generators and it'll stay at 6600 phase to phase. After it's distributed from the main switchgear, then it may be dropped down to 480 or similar. But the larger motors (like azimuth pods or thrusters) are usually fed the primary bus voltage to save on motor size and copper.
Just FYI WD-40 is a terrible lubricant. It's mostly a solvent. It works well for freeing stuck things but needs to be followed up with a proper lubricant otherwise the problem is going to return.
@@bryanlatimer-davies1222 that's were it got its name WD and the 40 was the 40th try at the water displacement formula. Was a contract with the military for a water displacement.
Thanks for the interesting video. WD40 is actually a poor lubricant. It is a water displacement fluid and tends to evaporate and disperse over time. A good quality synthetic oil or grease would be much better.
You may want to look into the life cycle of these VCBs. That Bow Thruster VCB is sitting on around 5000 operations which is nearing on the limit of its mechanical life, that is probably why you are starting to find signs of wear internally.
Ah. I just used it on my small 25ft sailing boat to try to fix intermittent contact with my automatic tiller. The WD40 for cleaning contact that is. Small world.
It was developed for use in the Atlas missile program, the WD stands for Water Displacement. So yeah, its been used for multi million dollar applications quite a bit in aerospace and aviation. As a lubricant, I think it sucks. Its a pretty good contact cleaner and fairly mild adhesive remover.
@@SteelDoesMyWill glad you pointed that out. The history of WD40 is interesting. 40 tries and an RFP from the DOD for a magical WD product that would preserve ICBMs.
Good Job Lucky Jake ! ! I am glad you are being extra careful & also that you have the necessary High Voltage Suit which confers the extra protection that you need while onboard & working with dangerous equipment. I would have the Captain always remind everyone during a all hands meeting ; that No One UnTags Any Valve or Switch or Breaker that has not been placed there by themselves & all safety tags must be known & approved by at least one supervisor ! There is no reason to lose the ship or anyone aboard it during these modern times. If all safety procedures are followed then everyone goes home with a smile & pocket full of money ! Good Luck , Lucky ! I had 2 electricians electrocuted while I was in The U.S. Navy & I can still smell the burning of their bodies in my mind when I recount the incidents. Keep yourself & your crew safe , keep them sober & get rid of anyone with a drug or alcohol problem.
Thank you very much for this wonderful comment. Messages like this will help me alot to improve my dealings with safety and to be better at my work. Thank you
Well done! Never cut corners when it comes to safety. My job is similar but it's on land. The highest voltage I deal with is 480v 3 phase from the grid. A ship at sea is its own power plant! Fascinating.
@MichaelKingsfordGray #1 he isolated the problem area. #2 he released any stored energy. #3 he used the proper PPE. #4 he tested for voltage. He didn't cut corners. He was safe. As far as the wd40 goes I don't think rebuilding or replacing the VCB was an option at the time so he gave it a few squirts. The bow thruster's back on line and he is alive and healthy. Arc flash is no joke especially at six thousand volts.
We have more mechanical issues with our high vol switch gear than electrical! Lol. Back in the day, the buss rails and plugs were made of all high quality parts and with regular maintenance would never fail. Now they try to save money and use cheap stuff.

Nice switch bounce on the VCB. Good example why they have springs and dampers otherwise the switch can bounce back partially closed and arc weld itself closed.
You are correct. I just worked on similar voltage stwichgear on a project and we used the correct silicone grease where needed. Perhaps it's not something they keep on board but I think they should. That being said, a cleaning with WD-40 might be all they needed anyway.
Wd40 not for lubricant. But to remove the hardened rust or corrosion. I think they use it for that. Then wipe it out. We don’t know if they used a grease specially for the contacts. But he did a good job on that lever
I sure hope when you get to Chile, you attend to the contactor mechanism service and lubrication properly since it is already compromised. WD-40 will do for now, but not for the long run.
WD 40 may be a better choice as it won't cause problems with the electeical. Except perhaps from dust accumulation. Would for example, a silicon lubricant act as a semiconductor, and be a bad choice around electrical contacts?
@@alakani yes I know, but I was referring to the dielectric properties. There are different types of silicone. I know some have good dielectric properties, I suspect the lubricant do not as much, as the better lubricants have smaller molecules.

They do need more regular maintenance than VCBs and luckily the one that went bang hadn't been maintained by us :-) I don't miss hand cranking the things either. Those tanks are heavy.
You really should put in more in depth explanation of why are you going and using this approach and what you needed to consider. Mainly, why the VCB could be opened with no load on the bow thruster? Is it some kind of interlock, or...?
It was actually specifically mentioned in the beginning that the vcb cannot be opened hence need to isolate the bus tie to manually open it so that it can be disengaged safely from the bus bar.
It must be a good feeling knowing you got such a serious arc flash suit on board. The danger of 6000volts is kinda impossible for people to understand until it blows up in your face.
I used to tour some factories and see “medium voltage” AC motors. While that does not sound scary at first think about this, 0-600v is “low voltage” and up to 4,160 volts is “medium”. I didn’t even want to look in the direction of those motors or their feed boxes!
Amazing video. Next time my home light circuit breaker trips, I'll head straight to the 50 cal arc flash suit and ensure the VCB is open along with the MBT. 😂🤦🏽♂️
i understand the good pratice as you did here, good job, but what kind of trouble is to have connected power to the bowthruster, linked with MSB if nobody operates the motor? You had connnection between MSB and BT, if you could operate BT in such way, after manouvering you could just leave breaker ON. Or there is some kind of protection on PMS that prevent to keep that?
The VCB is a protection component. In case of a overload or short circuit it protects the circuits to prevent fire and/or cascade failures. Without an operative VCB the bow thruster is not safe to be operated.
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?
You put wd40 on the mechanical parts but you referred to rubber worn off a pad or part what was that from and did it cconcern you ie getting a new pdf for replacement? I worked in the North Sea when the oil boom was on early 80"s and one catermaran tug had I its bow thrusters I think wired in revers and other problems, we went towards a lay barges and the thrusters cut out and we hit it blunting our stern and slightly damaging the barge, as it was running anchors and it was also doing survey work which I was involved in so the vessel I was not involved in, but if I was I would have had it checked over as it had a lot rong wilt it. Thanks for the technical video I'm wes in electronics and anything over 5 or 3.3V DC is doggy.
The dampers are rubber parts that avoids the metal to metal contact everytime the vcb opens and closes. With that kind of force the rubber acts like the shock absorber which in return wers off hence need to replace. To replace this we need to dismantle the springs and calibrate again, which ofcourse needs the special tools which is not part of our scope. We just tried to lubricate the joints to free them up but I am sure this will happen again unless the dampers were not replaced.
TY UA-cam. I have no idea what i just watched. But it was fixed with WD-40 which blew my mind. I imagine this is temporary until they can get the part they need on board replaced.
I had to spray wd40 on a 135kv vcb. The trip relays opened but the mechanisms had dried out grease on them. Gave the mechanisms a couple squirts of wd40 and then BAM! They slammed opened.
Your videos are really amazing and have learned so much. However I find the background music on every video is the same and very monotonous Can you please change it. Thanks for an amazing channel
Trying to compare ship electrics to ground based industrial electrical supply. Is 3 phase standard? I'm guessing the crazy high voltage is a compromise to run lower amps, meaning smaller wires running throughout the ship? What sort of control voltage is typical, is it digital comm cable buss circuits?
440vac 3ph 60hz typical, IGBT VFDs take it up to 3.3, 6.6 or 11kv for motors. 3x half redundant 720/900 rpm generators off the engine, smaller ships 1-2 megawatts total, bigger ships maybe 2x15mw just for main thrusters. 2:1 split phase 110/220v transformers for more mundane stuff. 24vdc relay control voltage, 5/3.3v digital. But it depends
Interesting to see that they use different color coding on the panels. For the racking they use green for "disconnected (i.e. OFF) and I'd assume red for connected (i.e. ON), which is what I'm used to seing. But on the panel lights the colors are reversed. Seems a bit confusing to me, is that a local thing?
I am entirely not one to speak on this system specifically, but I've seen on a printing press where 'contextual' indicators appear to clash: safety-context (red==danger; technician should stop//green==safe for tech to proceed) and operation-context (red==system/mechanism is stopped//green==system/mechanism is running). I too am curious if this is the arrangement for these indicators!
I'm always excited watching your videos, it feels like having a preview on what i am going to experience once i become an ETO. And i think it will be a great opportunity to work with you sir.
The suit is for flipping the switches. These types of high voltages switches used for industrial purposes can dangerously arc flash when thrown, killing or seriously wounding any workers near the panel. The suit helps protects from burns if the panel deicdes to arc flash.
2 guys are working on the emcy fire pump. They are changing the seal hence water spilled. But do not worry they have cleaned it properly after changing the seal.

I'm always excited watching your videos, it feels like having a preview on what i am going to experience once i become an ETO. And i think it will be a great opportunity to work with you sir.
good luck to your journey
That's some job you have! Interesting video thank you. 👍
Nice work. Very interesting engineering subject.
Wonderful vídeo
The part where he uses a stick is like when I wire a switch or socket up in my hose then use a wooden spoon to test switch it 😂

What exact was the issue in VCB that cause the issue in the auto breaker off on stopping the motor ?
so funny that you suit up to disconnect what you show us with your unprotected finger first. still a informative video
Yes! WD-40 to the rescue once again. WD-40 was invented in my hometown of San Diego, CA.
Duct Tape and WD 40 are like the best.
Great video!!thanks
Thank you

What is truster bow used for leckyjake??
It is use to maneuver the vessel when getting alongside or sailing out from the port.,
Well done! 👏
At 6:50 he sticks his finger into the hole in father front of the panel. Then explains why he needs the protective suit. I don’t understand…
nice catch
The suit is for flipping the switches. These types of high voltages switches used for industrial purposes can dangerously arc flash when thrown, killing or seriously wounding any workers near the panel. The suit helps protects from burns if the panel deicdes to arc flash.

You test the bow thruster while under sea? This does not disturb the normal sailing direction of the ship or do you correct for that with the rudder?
He was probably just testing the motor without it being connected to the thruster itself.
Cool, I didn't understand anything but I use WD-40 for a lot of stuff. 🤣
Love from india sir ❤️
Thank you for the support
SUBSCRIBED! love this stuff
Thank you sir for sharing your experience and knowledge sir,, are you a Filipino?
Yes sir
👍
I guess if you’re on a ship with no good solutions WD-40 to go to but they make a electrical specific grease for that type of equipment.
… and they wonder why the breaker stuck … what do you expect from Bodgit Philippines Inc …
Why is the bowthrusther room so dirty ?... I've been working on German flag vessels and there is everything completely clean :) good video!
2 guys are working on the emcy fire pump. They are changing the seal hence water spilled. But do not worry they have cleaned it properly after changing the seal.
When you have a ship full of cheap labor that grew up in third World countries, this is what you get. Pay for cheap labor get cheap results.

@@MrThisIsMeToo cheap labor, you mean 6 digit salary's, This is got to be one of the dumbest comments on youtube to date
