Cut and shuts

[Ruffian]

So saw this tonight.
Quite a feat of engineering.

Cut and shut a cruise ship!!

Fair play as that's a lot of work

Saved for later.

Chatham Dockyard (of blessed memory) used to do that to ‘ T’ class submarines. Not quite in the same league for complexity. But still an interesting engineering exercise.

If they get the cruise ship wrong, they can take to the lifeboats . Get the subs wrong and it'd have been ''Goodnight Vienna" .......

I think the Yanks did that with some of their wartime aircraft carriers some time in the 50's to make them long enough for jet aircraft.
ISTR reading that they scrapped about a third of the ships in that class but reused the centre sections to extend the length of the remaining ones.
Haven't a clue how you'd move a lump like that to position it for sticking it all back together though...

Saw that a while back, Very impressive! Also some of the sunken ships they recover are quite an interesting rescue operation

Isnt that one of the things theyre looking into with the disappearance of the Agentine sub in the South Atlantic. It had been cut & shut by its German builders to lengthen it.

I believe to split and pull back together part of the ship is on tracks and pulled away from the other half in some cases the piece that is fitted in is allso on tracks and just slid in to position then all pulled back to gether

Seems to be a fairly common thing.... saw something about the big container ships being done like this too

 

[Shox Dr]

It’s amazing how little they gain [in comparison to the rest of the ] but it must be worth it.

(I wonder if they used a Giant Rapidor to cut it in half)

I was just thinking the same thing... I wonder how many extra rooms they added... and how long that will take to cover the cost of the work ?

Few bits of pipe underneath it and a few hefty lads with bars would do it

 

[Wozzaaah]

It cost around $70m to extend it.

 

[PhillipM]

That's not going through the MOT.

 

[steve t]

where is it being done, shame its not being done at Harland and wolf.

 

[addjunkie]

All ships are built in sections these days, then assembled, this is the same thing on a bigger scale. Quite interesting when you see how its done.

You can't just lengthen a hull willy-nilly, there are various ratios of length to beam to shape to speed that need to be adhered to or you get a hull that handles badly or tears up its screws. They used to get it wrong on older ships and end up with terrible vibrations that either rendered the stern section un-inhabitable or it would destroy the props and rudder.

measure twice cut once! wots u bet the innards was done by Aleksander wojiski with a lidls jigsaw.
