Steel Ships - Emergency Repairs Underwater

Welders in wet suits?

He really does not give much to go on. So your suggestion is the best he will most likely come up with. Then again can't be to bad if he is asking here. I think the ship will sink before he gives enough information. I do have another suggestion lower the life boats.

HELP! SOS. Bluble, chock, blurb. Must....contact...CR4.....all we all shall die!!!!

in diving suits actually. i thought some vessels have the diving facilities in the first place. lol. first of all, what sort of repairs is he looking at that needs people to rush out of the vessel into the waters immediately and cannot be settled with easier alternatives before rushing the said vessel to the nearest yard for proper repairs?

if the vessel is supposed to be stationed far out in the seas, then during design phase that should have been taken into consideration.

some vessels are destined to be sunk without proper precaution taken. (thinks titanic) lol.

There ought to be a shipwright on board that has done it all before.

I have been in the diving industry for about 5 years now, and my family has since 1898. i can tell you whether it was back then or now, its not so easy repairing a ship underwater. There are many factors such as: coast guard regulations and rules for repairs, inspections,and so forth. Our main location is the Great Lakes and the way we fix a ship underwater is, 'we' (the divers) go under and find the crack or hole and depending on the size of it we assess what type of patch to put on the outside temporarily. most of the time the crack is in an area that is one of the ships ballast tanks. they then pump it dry and do repairs from the inside. All repairs are done accordingly to the Coast Guard. A person on board to do these repairs? eh, not so idealistic in the real world. And no, absolutely NOT to the idea of a person jumping in a skivvy suit and welding underwater. You have to be certified and trained to weld underwater commercially, which is big $$. Plus it is structurally not so great to just weld a crack. Ships are made out of a high strength steel that is not made to bend much , it just cracks, so when you have a small crack , its like a windshield, it will keep cracking with time and amont of stress. There is a procedure for stopping a crack from growing and again, lol by Coast Guard regulations..
