RL Leak Repairs?

[trongey]

I've always wondered how leaks were stopped from the inside of a submerged submarine. I've done some internet searches, but haven't found anything. Does anybody around here know how it was done in the WWI or WWII eras?

I'm guessing it didn't involve dragging around a bunch of tiny men then clicking on the compartment that was leaking.

I don't know what they did prior to this, but it's got some good pictures regardless.

When the wood comes in contact with water it swells and seals the hole.

AFAIK the same methods are used today

In the Kelsy Grammer movie Down Periscope they used a clamp for the main pipe and after the scene you saw smaller versions. Was that standard issue back then or just movie crap?

You mean the 'band-it' repair pieces? We had them onboard. They were supposed to be for emergency repairs only. However, from the decom stories I have heard, there have been subs cut up where they found them covered in grime attached to seawater pipes and such. They were used in ACTUAL repairs and just left in place and forgotten about.

When you have a leak, you use anything you can to slow it down while they isolate the path to sea. There is a standard DC kit. They have wooden wedges, twine, rubber patch peices, various sized conical wooden cones, and straps with the tightening tool.
