Worked on car engines most of my life. This is nothing short of astounding. The amount of actual work involved in this little deal is just mind numbing. That crankshaft is the most incredible engine component my eyes have ever witnessed. Would love to see how it's made. These guys definitely earn there paycheck.
If I could get to see things like this I may actually consider going on a cruise ship! Seeing all of the systems that enable these floating towns to operate would be my preferred way to spend time a cruise ship!
@@daveklein2826 Ordinarily, the thought of being on a cruise ship would appall me, but having the opportunity to see all of the systems that keep it operating would be of interest. I have absolutely no interest in any other aspects of the ship, like attending shows, casinos or cinemas, only the technical areas.
Many cruise lines offer behind the scenes tours. I’ve done one before. You get to tour the galley, engine control room (not actual engine room), the “I-95 corridor”, the bridge and the likes. Pretty interesting. I usually steer clear of the casinos and the money grab type activities.
I always skim through the comments during the video. I was like wth is crab canning a crankshaft. I immediately went to big screen so I could watch this process. I got so damn tickled at that...you got me. 🤣
Bel lavoro!!!! Mettere le mani su un motore, aggiustarlo, ascoltarlo quando si rimette in moto... Che soddisfazione! Bravissimi ragazzi, video esaltante!
This takes me back to Costa Smeralda ship project. I was everywhere in the engine room for 9 months. Seeing the engine running in the rooms is crazy loud and Hot!!
Truly impressive how they move the 7.5 metric tons crankshaft in a such a narrow space front the upper floors down to the engine. Was a bit surprised that the engine block had to be lifted up and then lift up the crankshaft and bolted from under. There must be a reason to do it this way anyway I find it very cool how they managed....
Because the bolts to the conrods connecting to the pistons will only be accessible from below. Plus the main bearings on the engine block only from below. Just like on a car engine. Some will do work from under the car rather than taking the engine out.
@@mcplutt I believe there's different designs which have the closure on the side, giving side access. And engines have inspection panels to suit. But in this case the crank shaft still needs replacing. And you can see the main bearings were accessed from below.
I have worked in shipyards every day for the last 15 years. I have to tell you riggers still never cease to amaze me. The stuff they move into the impossible places they move it. They earn every one of their dollars the hard way.
What I found the most amazing when I started working as a millwright was how natural the crazy rigging came to some guys they can just look at the strangest parts and have it flying and transferring in air
Watch ALE Heavylift performing a crankshaft exchange on ms Zaandam in Uruguay. The ship's old crankshaft was replaced with a new one, weighing 7.5 tons, via jacking and skidding techniques. Zaandam's old crankshaft was damaged at the bearing points from wear. The exchange took 3 days to complete following a week of preparation.
would have loved more details on this job actual time? the life of the old crank? the hired outfit that did this install? the total cost of job? was it planned or a mechanical failure? was this job in budget or a blow out? was the top end refurbed also? what engine type was it? what port was this? was this a non stop 24/7 operation to meet deadlines? do these engines have run in cycles? fuel burn per hour?
Would have been a lot easier to machine the old crank inside the ship. Just bring the equipment down. Personally I would have just done a bearing roll and some sand paper to polish the journals and call it a day.
Sailed on the Zaandam in Feb 2023 for 14 day transit through the Panama Canal. Crew was awesome, but the lady is old and shows her age not in a good way. Thanks for sharing.
Common practice using blocks of wood mainly hardwood in heavy engineering, metal on metal is dangerous as it tends to slip. Using wood is less likely too.
Most likely preventative maintenance based on hours of operation I suspect. Edit: If that is the Zaandam, my wife and I sailed on that ship. Good crew, steady ship in rough seas.
i remembered spending 10 hours measuring and aligning shims for 11,000 pounds Cummins generator OUTSIDE of warehouse times 3 for power emergency power generation the surface finishes on BOTH platform and engine bottom end must be absolutely at 0.00 some change and that is extremely expensive machining procedure. thats another reasons why massive marine engines like these cost in millions
"Jack points, designed for this type of engine" No shit bud, I honestly thought they went down to the local Autozone and got all of thier parts and tools they needed for this job
Music was too distracting, couldn't watch it. I would have enjoyed it. I oversaw the overhaul of a Fairbanks-Morse opposed piston 12 cyl. back in the '80s. Had to pull the 14 ft, 2-ton, upper crankshaft.
Sorry to say, but the working on height sfatey is not applied as the fall absobrbing unit is not correctly installed , the line is way too long , so in case of a fall the guy will hit the floor or will gain much more momentum than designed for the unit . be noted
@@DavidJohnson-hg1mz I've been on construction sites where something similar happened. They built the bottom part of a structure rotated 180° but it wasn't noticed until weeks later. It all had to be taken apart and redone. It's rare but it definitely happens.
Why does this crankshaft have to be replaced? A lubrication problem ruined a baring? I mean, a crankshaft is the most hardened part of an engine. As long as there is oil, there is life.
We do not need loud music, the video should be enough, it is distracting, a good voice over would be better and less or slower time lapse so we can see more.
It becomes obvious why they install engine first then build rest of ship around it. When big parts need replacing, work in tight spaces make it even more challenging. Crankshaft, camshaft, heads, pistons, etc are harder to replace in the field. One part that can't be easily replaced is engine block. That requires disassembly of most of engine, making hole through hull, over 5 million dollars, and weeks of time.
Ive learned how to land a 747, and now I know how to replace a crankshaft on a cruise ship, all thanks to UA-cam..
And that was just your Saturday morning! Next, the NASA channel! Get it done.
Better than college!
DAMN funny!
And build a log cabin on a weekend!😀

on a cruise ship? under a cruise ship? in a cruise ship? Lots of cruise ships are hiring
Somehow, the new crank, requires crab canning, and plastic injection molding. Sweet.
I always skim through the comments during the video. I was like wth is crab canning a crankshaft. I immediately went to big screen so I could watch this process. I got so damn tickled at that...you got me. 🤣
That procedure has clearly been allowed for since the day the boat was built , still a great job well done.
Excellent skilled workers 👍really great work crankshaft exchange is wonderful, thanks for sharing very useful videos congratulations 👌👌👌

I love the extras at the end. Huge surface grinders, injection molding machines, and a crab jar spinner.
Looks like all the lifting straps are new . SMART!
These procedures are so cool❤

Whoever planed this job and the whole crew earned one hell of a blow out as well a week on the beach.
Please note that no one died or got squished.
Music kills this.
I thought that so I turned sound off seemed to work
Turn it off!
What's with the random crab at 9:03?
Superb fabulous marvellous nice engineering smart work which is really of a master piece of engineering great video with a great skill
Amazing work.
Great video....but the music? Rather hear the real sounds and discussions going on between the guys.
Absolutely amazing
this is a ship i sailed on a few years back. this is pretty damn cool
Did they order that crank shaft from Rock Auto?

I didn't know Uruguay had engineering like that. So that's five things I know about Uruguay.
Pretty remarkable to accomplish that much work at that level of difficulty and necessary precision in only three days.
I would like to see them replace the engine block . lol
How many days from start to restart of engine?
would have loved more details on this job
actual time?
the life of the old crank?
the hired outfit that did this install?
the total cost of job?
was it planned or a mechanical failure?
was this job in budget or a blow out?
was the top end refurbed also?
what engine type was it?
what port was this?
was this a non stop 24/7 operation to meet deadlines?
do these engines have run in cycles?
fuel burn per hour?
Jij werkt als ambtenaar bij de overheid?😅
music feels like I'm in 1999 and playing Turok 2 Seeds of Evil
Always amazes me how short the throws are on those cranks.
That struck me too.

those guys earn their money.
I'm curious as the the total cost of an operation like this. Would a guess of $2 million make me look stupid?
I was wondering the same thing. That big of a crew is not cheap
Its a stroker now 🏁

Hopefully they remembered to use the Plastigauge.
Millwright’s we are beasts
WOW these guys must earn big bucks! Too bad I never did anything with my life lol
Captain: "Are we going to need to dry dock for this repair?"
Engine Room Crew: "I find your lack of faith... disturbing."
Would like to see the lathe that thing was turned on!
Fanbloodytastic team work riggers, welders ,engineering services Great 👍👨🏻🏭🇬🇧
nice ！！
Wow, talk about a short throw crank!!
Short throw, high compression, only four main bearings... a recipe for failure .
and here's me having a melt down with my KTM crankshaft lol... Amazing !!!
And I thought Audi built engines difficult to work on...! Kudos to the photographer as well.
for an engine that size the crankshaft looks so small. and the stroke of those connecting rod journals looks so minute considering the engine!! 🤔🤔
I'll keep this in my hip pocket so that when a cruise ship has a engine problem I can be the savoir and perform the crankshaft replacement.
Your having a really bad day when your told your car needs a new crankshaft, but when you own a cruise ship 😱
Can't believe they had Jenga holding the block.
Common practice using blocks of wood mainly hardwood in heavy engineering, metal on metal is dangerous as it tends to slip. Using wood is less likely too.
super interesting video, could have done without the synthesizer montage tho
I turned off the stupid music.
I would hate to get this repair bill!
As a marine diesel mechanic very impressed. The engine does not look very old. Warranty repair?
Most likely preventative maintenance based on hours of operation I suspect. Edit: If that is the Zaandam, my wife and I sailed on that ship. Good crew, steady ship in rough seas.
I was working on the ship at that time - the shaft was out of spec for a maintenance plan.
Needed new bearings from wear is what i heard
I use to work in a place like that made those crankshafts.
Fascinating, but I wanted to slit my wrists after listening to that soundtrack.
I'm surprised how short the stroke appears to be
thats what your mom said.
There is so much better royalty free music out there.
how many cylinders? 6? what engine is that?
This is a 12V !
How much hp she puts down bud?
Specs on the cam? I'm looking to get some punch in to my '66 Chevelle.
Trade it for a mopar
Engineers rule the world. The average people think it's mere politicians.
You don't wanna drop that on your toe.
Why no guards on the journals? One ding and all is lost!
That's actually a small crankshaft for a cruise ship! Is this driving a generator?
What happened at the end of the movie clip ???
It was fitted, put back together, run up, run in, back in service, we went home.
It ended
The passengers watching want to know, “How much longer?”
5:51 hol up, "last minute" and "risk assessment" usually don't go well together
Why are there no mounting holes for the alignment brackets .
Welding them and then grinding the welds of seems a little adhock.
This is me lifting in my new sofa alone LUL
Why did it need to be replaced ?.
FYI, that is not the main engine crank, not even close.
Lol, there will be an exam after watching this video
would be interested to know what the failure of the old crankshaft was. seems like it failed very early in its service life.
how I feel when I change my oil in my car
Is no one going to mention the crabs at 9:00 in what appears to be part of the intake strainer system?
Would this be a good crankshaft for my car it has 300 hp. I dont know if it can handle it.

🤝👍
Sent old one off to be refurbished, yet only install new? What is the point of sending off for refurb if never to be used again.
Engine mechanics: [aligns crankshaft under block]
Also engine mechanics: "the crankshaft is backwards, take back out and flip it around!"
🤔 yea no. Highly doubt that would ever happen in this situation.

Dude, who forgot to tighten the bearing caps
With enough chain falls and rigging points, I can move anything. You would be amazed at what goes on in engine rooms, especially during a yard period.
So if the block goes bad do they have to cut the ship open to get new one in?
@@69jbr69 Yes!

@@gibbogle9486 I've never seen a large diesel up close, have you? It would be quite the sight.
This crankshaft is so tiny against the giant crankshafts of the main engines from Olympic, Titanic and Britannic.
The music was way over the top and distracting, yes I turned down the volume to watch it.
Makes me wonder how you actually know that it requires replacement 🤔 ???
Low oil pressure due to failed main bearings is my guess.
Only 4 main bearings in a ship engine of that size and horsepower.
The big question is WHY? What happened so that the crankshaft had to be replaced? Seems like a failure that just should not occur...?
Only 4 main bearings, that's why .
