How to rescue person or animal who were trapped in a cabin of the capsized vessel?

Are there any mature technologies or cases?

No.

Scuba equipment and trained rescue divers.

 

Back about 15-20 years ago a friend of mine cut a hole in a hull in the bottom of an overturned fiberglass boat and saved 2 out of the 3 occupants. Used a chainsaw and had the hull cut before emergency services made it on scene. Was given a pretty high award for his quick thinking and action. Met one of the guys he saved after his passing, said he'll never forget the diesel smell or his rescuers face nor the strength in his hand when he drug him out by his collar (friend was built like a black bear and kinda walked like one as well).

His wife has the article about it and the Coast Guard award framed.

Granted these were 40 foot fishing boats not container ships.

 

Every rescue is a unique casualty event....Only luck, knowledge, and skill aids the rescuers.

 

Thanks for your reply！ It is dangerous to cut a hole in a hull in the bottom of an overturned fiberglass boat, because the stability is changed in most cases. Your friend is lucky.

 

Why can't we deal with the rapid development of the world's economy and technology? Is there too little attention paid to offshore engineering, or is the economic value of this project low?
Is the widespread appeal conducive to promoting the optimization of handling such dangerous situations?

 

It was on the beach in the surf. Not much stability changed in cutting a big old hole. Luck, crazy, who knows. Takes something to risk being crushed by an overturned boat.

jehardiman is right every situation is different, in the above story it was 100 feet either way and it was jagged rocks not gravel. Story would have been 3 lost souls then.

Lost a friend in 12' and there was only one survivor. He described the effort it took to push against the inflow of water against the door. He'd got up a few seconds before needing a smoke when the lights went out and over it went. That one was a sheared off pvc pipe that caused down flooding, rudder locked over when the power went out and the slack tank in the engine room rolled it right on over. Figure the pvc fitting had a stress fracture from vibration being in proximity to the main. The give a mouse a cookie line was, old steel valve had corroded over many years, so it was replaced with maralon. The maralon had leaked badly several months prior so they had swapped it out with a sch 80 pvc valve.

Most would say it was bad choices, but I'd say almost half the vessels up here have pvc plumbing on their fish tanks, and for all its vaunted value I've never had a maralon piece that didn't fail. Whilst my plumbing is frp or silicone bronze, it's not exactly outside of standards of practices up here to use heavy pvc. Just in that instance it cost four souls. Maybe it was economic but the boat was quite lucrative and had plenty of reinvested money. Likely it was a fix of what happened to be there and everyone was more concerned with other things.

That pushes the hard reality that sometimes things happen, neglect or bad decision can factor in but sometimes the reaper just comes a calling. It's impossible to prep for all eventualities, and everyone has a different view of risk assessment.

Topic reminds me of an incident in Finland decades ago. A push tug flipped and most dies but two survived.

google translated part that talks of the rescue (at points it translates rescuers when it should say rescuees)





youtube footage, in the news bit they say 10 dead, not knowing two were alive.

 

Nothing to it, really, there is even a full training film.

Due to pressure hull, aircraft might completely submerge with live people inside.

It is actually not that rare, but putting a hatch in the bottom of a ship for the unlikely event of a survivor would just lead to more casualties.
