Biggest sea's I have ever seen

[jenkotvr]

Scroll to 0.50 bearing in mind how big that tanker is:

I've been in some fought sea's in the North Sea, around Africa, etc, but bugger me, that looks fairly massive.

1.30 onwards

I swear to god I would cry like a baby.

I am surprised it's back does not break.

They do flex quite a lot, watch (and listen) to this video from 0:12...

Everything flexes until it breaks

On a serious not, I was under the impression these ships were built, and sailed, in compartments. Each 'block' of the compartment rising and falling independently.

I have no idea why

Wow, I am amazed how much movement the ship can cope with. I would have thought a couple of weeks exposure to such flexing would have fatigued the metal out of use. Dread to think how much punishment the structure goes through over the vessel's service life.

Fatigue is an important consideration in the design of ships. The designs are calculated such that the maximum expected loads remain well below the yield strength of the steel - this means that even repeated bending such as in that video won't result in fatigue failure. Ships intended for harsher working conditions, such as those doing the North Atlantic crossing like Queen Mary 2, have to cope with higher loads, and are built much stronger than say a cruise ship expected to go from Caribbean port to port in fair weather. If you were to use a lighter built ship on such a route then there is a possibility of fatigue problems - several ships were lost in WW2 because they weren't built strongly enough for the continuous pounding they took on convoy duty.

Other metals like aluminium don't have a limit below which fatigue can be avoided in the same way, and any cyclic loads can contribute to fatigue failure. That is why such care is taken with aircraft, and why they are assigned a working life beyond which it is deemed the risk of failure is too high to continue using them.

those ships are built with that flex in them because if they were built to be too rigid something will break, which will be the welds holding the ship together!

Jeez! That corridor shot was like looking down the carriages of a tube train whilst under way.

Gold!

[Changedmyname]

Imagine doing a Titanic on the front of that!

As a yottie you tend to think "now matter how rough it gets, just shut the hatches and it will be OK, perhaps a bit of pumping out and very uncomfortable, but it will be OK..."

Er, perhaps not!!

[LimaDelta]

I've been through some pretty rough stuff in my time at sea, but one thing I do know is that as soon as you point a camera at it, the sea calms greatly. No matter how bad it looks in that footage, I'll bet it looked ten times worse from the wheelhouse! Scary stuff.

When I was a young'un I worked on a pair of trawlers out of Peterheeeeeed... Got caught in a Spring storm and at one point we thought we were going down as the boat was overloaded with fish and had the sailing ability of a block of lead. But this video is something else...

Agree with the poster above - film rarely captures how bad reality is...

[mrloudly]

Interestingly I just met with the QM2's director of entertainment whilst flying back to Blighty from Sydney. He was telling us
some really interesting facts about the vessel. 28' to a gallon She's 40% heavier than similar sized non Atlantic ships, thus designed to withstand
the beating! If you google QM2 Entertainment Director, he has produced a couple of really interesting videos about the ships recent re-fit.
As you would expect, a really nice guy!

I'm surprised the front didn't fall off.

[lost in espace]

I see your 1.30 and raise you 2.06! holy cow!

[jenkotvr]

OK so if the weather wasn't bad enough, what would of happened if the engines had failed?

Drag anchor?

Would have been OK if it had though, they'd taken it outside the environment.... there's nothing there.. lol
