how do they test submarines for pressure and leakage before just plunging to the depths of the ocean?
In: Engineering
We know the strength of the steel and other materials the pressure hull is made of, the specific design of the submarine, and how water pressure works, so it’s not hard to use computer models and simulations to determine what depths a submarine can withstand. When built, submarines have a design depth, which is the depth they’re designed to be able to withstand. Then during sea trials (sea trials are the usually lengthy period when a naval vessel is tested at sea before deployment to make sure everything works as intended), the submarine will actually be taken down to various depths to ensure it performs normally.
