Tsunami Flipping Ships

03/11/2011 12:08 PM

I see on the news, what appear to be 300' ships in Japan, entirely capsized, and laying on their decks hundreds of feet inland. What is the heavy equipment technology involved, in righting these massive ships when they are stranded upside down in the middle of a coastal village? Can they be turned over again? Or will they need to be disassembled? I don't know the actual weight of a ship that large, but are there cranes capable of the task? Can the structure of a ship survive being rolled right side up when it is laying flat on its top deck like that?

The pictures of the damage are quite astounding. I wish our Japanese friends well.

I don't know and it is a good question.

However, someone named Joe on a completely different thread claims that they have a patent pending for a device that can harness energy from the wind with a force exceeding an atomic blast, so maybe they should be consulting them?

Wow.

Here is a 1 min video of the ripple... the entire Pacific will be affected in 20 hours.

Just plain old Wow.

Well the tide was a bit low today. We should see minor increases later this afternoon on high tide, if at all. We had enough of the wet stuff for a while anyway.

The forces involved here are hard to comprehend. Even compared to a cat.5 cyclone that hit us a month ago. We are put in a place of insignificance and have to be prepared for the worst case scenario, never mind were we live or how many Towering Infernos we have watched with our adrenalin pumping.

The unthinkable has caught up with reality and she will not sit still, our wonderful planet. No rest for the wicked.

If I could only be of help , anything, Ky.

Don't forget there is an inverse square equivalent happening with the expansion.

But equally, I'm told, that the Sumatra one registered (to some extent) in tide gauges world wide.

It is one planet - but the problem is mainly being on the quakes doorstep.

The Japanese have been there, their entire history - hence the lack of lives lost and few structures damaged.

Ref the ships - as ~Anon~ said - and I might add, they are quite practiced at remediation. Not to say "oh this is nothing" because it certainly is yet another economic blow to a country struggling for nigh on 20 years.

And it's a country and people I more than quite like.

I don't think the term "lack of lives lost" is really going to apply in this disaster. It sounds like the toll will easily rival America's own 9/11. Perhaps in multiples. Despite their experience and preparation, much of the affected area had literally 5 minutes of warning. And this wave rushed in more than 6 miles inland. Six miles! That's simply unbelievable. And I'm sure there were many that never fathomed a 6 mile surge.

Granted, most of the big buildings withstood water and shaking, but 5 minutes is basically no time at all, for something so insanely powerful, massive and overwhelming.

Some things you simply can't prepare for.

I very much hope I'm wrong.

Sorry

I was following this and thinking in terms of the Sumatra toll.

Next, I might be wondering about San Andreas, but oddly not that politics is at fault.

Structural engineers will examine the ships for damage and report submit reports so it can be determined if it is cheaper to replace the ship or repair it.

If it is cost effective to repair, it could be righted with cranes, air bladders and rail tracks assembled underneath so it can be returned to the water.

If not cost effective, it will be scrapped.

Further to Anon's comment: Not only is the structure in question, but the machinery is an even greater cause for concern. The engine bearers in a ship are designed to take quite a lot of abuse, but I don't know if they can hold the engines in place with the ship turned turtle. If the machinery has torn loose, the ship probably will have to be scrapped even if the basic structure is sound.

Actually, I think that it would be either a Maritime Architect/ Engineer that would have to check out the structural and machinery integrity of a ship rather than a Structural Engineer, who is essentially a Civil Engineer by training.

For ships as large as 300 foot I can imagine that you'd lay the ship for scrap piece by piece where it rests, just like they do in many 3rd World countries. That is not exactly the most environment friendliest method from what I've witness on a couple of TV documentaries this past few years. I can't imagine how they could transport one of those monsters to the sea if it's located more than a few hundred yards inland or more. May be possible to move a much smaller boat or ship, but by what means I haven't a clue????

LOL

I suppose they could levitate the ships much in the same manner they levitated all of those millions of huge limestone blocks for the Great Pyramid at Giza!

I can just imagine all of the Japanese bowing to the Aliens in unison, then later on designing and manufacturing millions of "Alien Transformer" toys for our American brats to play with and worship! LMAO

Cranes? Not likely.

It looks to me like its time to call Brandenburg Demolition to mobilize a fleet of demolition shears and scarfing torches.

Typically with large vessels, structural integrity is checked, holes patched, and a channel is dredged. The engineering behind the controlled chaos is amazing. I have seen them move large barges and ships that were a 1/2 mile inland. It took less than 2 weeks.

Re: Tsunami Flipping Ships

In 1977, there was equally devasting Tsunami in India, near Machhalipattanam, east coast. During those days, the name Tsunami was not so well known. The sea waves penetrated to 8 miles inland. Fortunately, the area was (and not is even today) so well developed, to see such great damage of property. But loss of lives was around 100000. The humans and the cattles were found hanging on top of the trees some 50 feet high.

One ship landed few kms from the shore line and water receded. The ship was there on land for many years (i am not sure if it is still there)

But this Tsunami was not because of any earthquake. It was because of very huge storm.

Also the survivors claim that they saw flames in mid sea, when storm was in full swing.

Can anybody explane the phenomenon.
