Real Rolling at sea!

[Tonka's Skipper]

Just a peek of a really heavy roll on a containership at sea! That is about 30 degrees..........makes the light rolling on a cruise ship seem unimportant, doesn't it!

Wow! Impressive!

Wow!

 

[ludari]

Impressive.

That made my stomach jump just looking at it!

It's incredible to me that they're able to stabilize all those containers. In this picture you think they all go flying into the sea.

 

[Tonka's Skipper]

On deck, the Ocean Containers have in each upper and lower corners, a *corner casting* with a *twist locks* which fits between the corner castings above and below and as the names implies, locks them together and to fittings on the vessel. In addition, the lower 2 or 3 tiers of containers also have crossed *locking bars*, which further secure the containers in place.

In the holds, the containers are stacked in *SLOTS*, with each corner secured with VERTICAL *L angle * steel brackets.

The system has been around since the late 60's and is remarkably simple and does quite well holding everything together. Of course that does not mean every now and then there isn't a problem.

I seem to remember a statistic that about 10,000 containers go overboard and into the ocean each year worldwide, never to be seen again. I guess that's just a tiny fraction of the number shipped each year, but it still seems like a large number to me.

This has always been interesting to watch.

Thank goodness for the stablizers on the cruise ships!

Ships do indeed *hog* (meaning they bend upward in the middle) and *SAG* ( meaning they bend downward in the middle hull bends). On a rough night at sea, all those little noises you hear is the hull bending and twisting. The ships are designed that way, to relief the stresses.

We had sleeve joints on pipe lines on the tankers (40,000 tonner). On the rough trip you could stand on deck and watch the sleeves move in and out up to 6".

I don't remember that number SuperDry, But I wont say its wrong.

I know. Just as a bike bends, a car has to flex and planes deflect as well. If they didn't they'd fall apart from stress and fatigue. It's just an interesting video to watch for those who've never seen it.

Love it! When I served on an LST in the USN, we were in a couple of storms when we rolled over more than 45 degrees and there were several times I didn't think we'd come back up, but we did, only to repeat the experience on the other side.

I had a bunk on an aircraft carrier that would frequently hog and sag. At first it was annoying, but I got used to it so that I missed it when it when I was reassigned to another stateroom.

How about this one:

2003, Alaska, Radiance of the Seas. I hadn't thought about the fact that we were coming out of the inside passage in the middle of the night to get to the glacier. I woke up, FREAKED OUT by the noises and the shifting and the rocking and swaying. Didn't know what was going on. Our oceanview room was at the bow, overlooking the helipad. I kept trying to wake up my brand new DH, trying to get his words of wisdom. His dad was Navy/Merchant Marine/shipping, and DH's first jobs were for his dad on ships, and then on oil tankers in REAL Alaska waters. He slept and slept. He wouldn't wake up for more than a "it's OK" mumble. See, that rocking just put him to SLEEP like I've never seen in him, because he misses a life at sea.

I finally got to sleep, practically sucking my thumb in a fetal position, having worked out that if stuff wasn't falling off the shelves, and the clever little storage areas were staying closed, that it was probably OK no matter how it felt to me.

In the morning at breakfast we sat next to a couple from Canada, and the wife was talking about how rocky it had been. DH launches into a fabulous explanation of the ship and how you WANT it to bend, and the creaks are part of that, etc etc, just this big long explanation, and he nearly got his coffee dumped in his lap. Where was that explanation the night before while YOUR wife was nearly in tears, Mister?!!???

I laugh about it now.

We want skyscrapers to sway a bit. We want ships to bend a bit. Even though it feels totally wrong.

Oh Deb, I hadn't watched that before I posted. I think I'm gonna be sick and pass out just thinking about being on that ship. Wowza.

 

[C6PT7]

I'm glad you don't see cruise ships flexing this amount!

 

[maxiesmom]

You guys are doing a great job of convincing me to never go on a cruise!!! Eeek!!
