What happens if a submarine has a leak?
Submarines always have small sea water leaks. This water is collected in the bilges and pumped overboard as necessary. When a leak is sufficiently large that it cannot be handled in this manner, it is called flooding (see damage control).
Submarines generally stock a 90-day supply of food, so they can spend three months underwater. The diesel-powered submarines (not now used by the United States Navy) had a limit of several days submerged.
What is a moon pool in a submarine?
It is an opening in the floor or base of the hull, platform, or chamber giving access to the water below, allowing technicians or researchers to lower tools and instruments into the sea. A moon pool also allows divers or small submersible craft to enter or leave the water easily and in a more protected environment.
Can a submarine submerge in a lake?
There are vessels that submerge in lakes, but they are submersibles and not submarines (that is, they have a limited range, only carry a few people, don’t carry much in the way of supplies, and are dependent on a support vessel). So any submarine that has a leak will be taking on salt water.
Why do submarines have salt water leaks?
Submarines have salt water leaks all the time. Pump gland (seals around the pump shaft) and the main propulsion shaft seals are designed to have a small amount of leakage for cooling and lubrication. There are other sources as well. These leaks go into the bilge and are periodically pumped out.
What kind of water comes into a submarine from the outside?
Well, first of all, ANY water coming into a submarine from the outside is going to be saltwater since submarines tend to work in the ocean.
What was the name of the submarine that was lost?
Submersible projects date to the 1800s. Alligator was a US Navy submarine that was never commissioned. She was being towed to South Carolina to be used in taking Charleston, but was lost due to bad weather on 2 April 1863 off Cape Hatteras, North Carolina.
