Ok, if you own a ship with 2 main engines each kicking out 9600HP make sure you do the Big Ends up properly otherwise this might happen...

""

and the piston will get stuck in the liner...

""

and the block will be smashed to pieces resulting in bent push rods ..

""

oh..and a new block...that'll be 1.9 million euros please...
""

old block out

New block nearly in...
""

lowered down through hole cut in deck into engine room..

DONE

dude i work for Finning Caterpillar , that ship was a RFA ship...get involved..they toss it off BIG stylee..lol

fatty

worth noting that the RFA ( royal fleet auxiallary) dont ACTUALLY do alot of work themselves..hence why we get called in. sound bunch tho. Worse still is the RN , they are slack as hell lol big boys club.

next time im down at my twin engined 9600bhp ship ill check the big ends have been done properly.

JonnyBravo

Thats a rather large engine !

Being that the engine I guess is assembled by a few people what happened to the guy that incorrectly torqued that big end up !

How long does it take to remove and refit a engine ?

fatty

Well, they've had issues for a while with these engines because for some reason theres a washer on one end of the Big end Bolt and if its not located properly when they are done up ( 2250 BAR ) it basically rattles loose and heres the result. We've done the big ends dozens of times and always made sure this washer was in place but it seems it was one of the ships engineers that cocked up this one. As regards what happend to him , not alot i dont think. It hard to pin it on one guy ( but we think we know who it was ) and as usual it all kinda gets lost in the paperwork trail.

The old engine was out in about 2 days, that includes cutting the hole, unbolting the coupling , pipework , removing cylinder heads and other bits .
It was done in Hamburg using Blohm and Voss shipyard ( where they built the Bismark ) and the yard labour were shit hot. Literaly 14 days to get the old one out, the new one in, line it all up , bolt on the pipework and make some alterations and then weld the deck back in etc.
Good going for ZEE GERMANS

JonnyBravo

lol @ that ^^^

You make it sound so simple.

We had a discussion round mine the other night after looking through that out shipyard thread and some more current ones, what exactly do you use to tighten a bolt to 2250bar ! Some of the tools must be ridiculous !

TurboShed

fatty

lol its basically done using the stretch in the bolts. If you look in one of the pictures at the top of the thread you can see them lying on the pallet. Its done using hydraulic jacks that screw onto the thread at the end. the jacks are then extended ( only about 5mm) to 2250 BAR ( on a maximator air pump ) using oil and then then nuts are tightend down the thread and the pressure let off. Same for the cylinder heads and main bearing caps. The flywheel bolts and other BIG bolts are done using a torque multiplier. Sometimes it involves using a big bar and inch drive gear.
Hope this makes sense, its not easy to get your head round lol.
The REALLY big two stroke stuff uses the same principles just bigger jacks and nuts.
The jacks themselves are about the size of two bags of suger so are man handelable.
Its easy to get wrong but once you;ve done it several hundred times it gets easier .

JonnyBravo

Great info, just spoke to my mate who is a fitter for Scania, he asked the initial question and was quite impressed with all that as that's totally his sort of thing.

If there are any jobs going let me know and he'll drop your company a cv

fatty

Ah Scania eh? lol yep they're always looking for people. best thing would be get him to email me and ill have a word in the new year. Its home based ( ) etc.
The boss is a bit of a bell-end but who knows what might happen.. lol

JonnyBravo

Cool, I'll let him know, I'm like a kid in a sweet shop walking around his work looking at what I consider to be big engines, clutches etc. but then you post things like that !

Some of the stories of he roadside repairs he has been called out to are hilarious, one being a small rattle coming from the engine which turned out to be half a block missing and a rod hanging out through the side LOL

Like ship engines when those sort of things let go they do it properly ! only more expensive !

Feel free to post more pics, I love stuff like this and plenty others on here do too !

oh and PM me your email !

fatty

lol yeh its all fun and games! couple of the guys i work with have moved over to the marine side from working on Caterpillar Construction so they're all into their diggers and all that stuff, another guy's ex Mercedes etc. so its a mixed bunch really.
I came from Wartsila which is another big marine diesel engine firm . If your mates keen then its nt a bad crack really, obviously its not all shits and giggles but it pays for my house and Rs's lol also , in the last two months ive done 3.5 weeks work . ideal

just popping out, ill try to remeber when i get bk / tmrw about the email etc. ill have a rumage for some pics aswell..got far too many lol

ta - ra!

is that a big fooking turbo strapped to the top of it? if so do you reckon a cvh could spin it up lol!!!!

Who gets to weight the old block in

Glenn_

iTrader: (1)

Fook me thats some size.

Turbo Pez

Im a dockside crane driver, so been on a few ships in mine time, lifted a few engine parts on to them, pistons etc, and they are rather huge...i have sometimes thought how the hell do they change the engine if it goes boom, some are stuck right under the bridge's etc, now i know just cut the boat until you can get it out

Also notice thats some crane lifting it out, dont look like much but has a S.W.L of 200ton...

MikeR

Blom and Voss, they have just built Abramovichs new boat, bloody good ship yard by all accounts, what type of boat was this on ?

Mike

jammerrs

may be a daft question but...how many litres is that engine?

Turbo Pez

I dont know the answer to that, but prob runs on oil, most do if im correct!

dug112y

iTrader: (1)

i seen bolts like that the other day.............holding the forth road bridge up!!!!
no ARPs in here lol

fatty

yep its a big fukkin turbo lol. trying to find room in the xr2 for one but struggling..oh and they're a bit dear aswell

fatty

the block weighed in at 160 T i believe, thats minus heads etc. You want big cranes goto Schiedam in Holland, they've got the Mommout deep sea rigs etc..thats BIG lifting lol

fatty

Correct, it was there in another dock when we were there. This boat was a RORO ferry used for the army to shuttle stuff around . its currently heading to the Falklands.
Hopefully on Both engines

fatty

Yep, they run on MFO or HFO , diesel Oil or Heavy Oil which needs to be heated first

the Heavy stuff is a cunt to work with, they shoul dnever shut the engine down on Heavy but some do.
As a link , the Chief Engineer onboard owns a Mint Escort Cos , He's in the Durham Rs Club if anyone knows him...Steve

pacwest

fixed.

fatty

lol the question on everyones lips ..do to the 'composit' casting you cant actually weigh the bastard in , its the wrong type of metal 'apparantly'

theres a crankshaft going tho if anyone wants it?? lol

fatty

its done on Hours, the old one had 36000 hours - ish

pacwest

I was referring to volume - square kilometres.
