Sometimes it's a tight squeeze but the right people can make it look easy.
You're not in south Georgia!!!
It's good when a good plan comes together. By the head count, it took near all of them to pick it up.
At the end of the day, no damage to the ship and all go home with the correct digit (finger) count, It was a good day.

This one might leak.
Its done in NZ so no worries there mate
Of course I was joking about it leaking but what is NZ?
Back to the task at hand ...
I am imagining the effort needed just to prepare for the main job.
It looks like they've taped luan or underlayment to all the cabinets and walls for protection against a misguided wrench.
Lots of planning before you even set foot inside the boat.
Is that a camera above the counter in the ceiling or a light fixture ?
Makes going to a turbine look easy...
Anyway... what needs to be done gets done! I have often wondered why they just don't:
1. haul the boat,
2. Cut the bottom out under the engine,
3. lower it out,
4. Install the new engine,
5. Jack it into place,
6. Weld the bottom back in, and
7. Away you go... not much fuss or mess!
With modern cutting and welding techniques it is pretty simple. And, it keeps the mess in the engine room. Saves all that protecting fancy stuff, horrifying the ladies when they think the grease gob and it sweaty attendants dragged it through the salon, the black stain on the carpet and all that aggravation. And, the evidence is underwater where few care to check... other than yard workers and fish!
Navies do this plug and play all the time with no harm done. ONLY way to do anything on a submarine... the EASIEST way to replace equipment on a ship.
Sounds as easy as replacing a stove in a kitchen. However, I think you might have missed a couple of steps.
We considered going thru the hull on a houseboat Roamer. Lots and Lots of plumbing and electric stuff we really did not want to mess with.
Lucky, problems were resolved and a new block was not required.
We had a customer with a Deerfoot and he went in thru the hull for his engine change out. Re-finished hull and you could not tell anything had happened inside or out. Think that work was in NZ also.
I'm sure there is a balancing of work either way it's done.
1 2 3 4 5 6 7 8 9 10 ...
Was this boat that had one engine blow up just after delivery to a new owner?
Well maybe there's just a little bit more involved... but
simplifying it and explaining it to you guys is like trying to explain:
"Wham Bam Thank You Ma'am" to a French lady... it don't translate... and it just isn't enough!
YF you might want to downsize that picture! I am not mechanically inclined enough to !
NO, the blue one was just a "normal" engines and generators upgrade. The gaping white cavity was left over after removing the engine because some clever fellow thought it was OK to place the main bearings in series with a welding ground.
An engine that never needs a reman (out of the application) would be better or maybe one with light enough and small enough parts to be taken out through a small opening. The expense in these pictures is huge.
