you probably voted : what where they thinking?!

Correct

I have a feeling that 2013(my guess) when the ship is going on maiden voyage, people will say they dont like thip.
cause they all get lost.

Like in the famous phrase: Every ship floats.

i hope so

and if it doesnt float i will laugh

I am sure the naval architect in charge will make sure she will float

Besides the length won't make a difference to wether or not she floats - the long length means she will displace more water so will make up for the length

I am sure it will float and work, if it was that questionable, they probably wouldn't risk to build it. But I just don't understand why they feel the need for such an big ship, certainly seems like madness to me.

It is not so much a question of whether or not she will float when they launch her, as whether or not she will break in half the first time she is in bad weather.

As has been said above, I am sure the naval architects will have calculated all of the bending moments and stresses, but i wouldn't like to be onboard when those calculations are tested in the real world.

i agree with you clanky

It will float, but still... are they going to even build the Princess Kaguya

oceandream · « **Reply #35 on:** February 22, 2010, 02:06:36 »

yes the japanese are planning too

Where's the official word on this?

McGherkin · « **Reply #37 on:** February 22, 2010, 07:48:07 »

So when are you modelling her Shane?

Well pointed!

Hmm.. So what you are saying is that it is a very expensive form of "trial and error". Like the Tit...ani...c

What who is saying?

Stuart2007 · « **Reply #41 on:** February 22, 2010, 12:49:55 »

Some of the people here who are saying maybe it will float, maybe it won't...

THOSE people.

Before any design is approved, it is tested in model from and the stability and stress criteria are calculated by the classification society and / or the flag state (not sure on the and /or part, I think it varies between classes of ships).

If a ship is built it will float and will be stable, the problems come when trying to assess it's ability to withstand the physical forces on the hull. The methods used to calculate these are very advanced, but they are when all is said and done a modelling process, it is impossible to predict exactly the stresses on a hull for every sea condition.

But when was the last time you heard of a ship breaking up in bad weather due to design rather than old age and corrosion?

Stuart2007 · « **Reply #43 on:** February 22, 2010, 13:03:32 »

Hmmm... A long way back- maybe the US liberty ships, were a good example.

When one looks at the way these things are being built- (the programme about the building of Oasis of the seas) it isn't so much the brute strength of the steel but the way it is built, with everything working together rather than against...

After a challenge on TV years back, myself and a few colleagues wanted to prove it was possible to drive a truck over beer glasses without breaking them... so upside down they were, we drove over and stopped 13 tonnes on top of upturned glasses. But the glass itself is weak if you did it with the glasses on their side...

So, in other words (for the benefit of those who don't understand engineering (ie ME)) that if your ship hits an iceburg, the beer glasses will be the only thing that survives

clanky · « **Reply #44 on:** February 22, 2010, 13:09:20 »

Indeed, ship construction methods have come a long way since the liberty ships.

With all of the fuss over the Derbyshire tragedy and the suspect design which it was believed had led to a massive structural failure they eventually concluded that (as with most disasters at sea) human error was to blame.

Not only have the ship building methods improved, but the design testing has improved. Like I said above it is not really possible to predict exactly how a hull will perform in every sea condition, but they are closer than ever before to doing so and I can't remember a recent case where they got it wrong.

My only reservation is that the methods used at present are known to be accurate for the types of ships which are being built at present, but as ship design takes giant leaps ahead rather than small steps these methods ill have to be looked at carefully to ensure that they remain valid.

oceandream · « **Reply #45 on:** February 22, 2010, 19:49:16 »

well what can i say.......
what youve said is wright.
but one way to make sure things like the derbyshire happen wont ,is to dubbel or even triple the hull.
if its already been sad i know it than

Stuart2007 · « **Reply #46 on:** March 01, 2010, 20:58:02 »

Clanky, the Liberty ships were known to have faults, but there was a war on and if a few sank, that was bad luck for the crew but no big issue for the powers that be.

However, when investment banks are putting up millions, they will have engineer after engineer consult, re consult, get drunk, lose their blue prints, go on holiday, forget what it was they were on about, come back, claim expenses, and re-read all the reports before they say there is a definate chance that it maybe might be 50/50 whether it sinks or floats (but there is only a 17% chance of them giving a 50/50)

Never. I can promise you that. Seriously, I find the designers of this ship to be quite immature. I think they were going for the records, because I don't think the industry quite demands something so large. I feel that if it was, wouldn't most ships be this big?

McGherkin · « **Reply #48 on:** March 01, 2010, 21:55:57 »

Don't worry, I didn't think for a minute that you would model her...

Only pulling your leg!

Daniel Cho · « **Reply #49 on:** March 02, 2010, 06:11:55 »

i think the ship should be a little flexable so the ship wont snap in a storm.
