This technology pertains to the storage and retrieval of large amounts of piping within a submarine, carrier ship, aircraft carrier, and/or other types of equipment, such that the piping is retrieved / inserted using vacuum tubes with rollers, there are multiple layers of airlocks such that the piping may be inserted and/or retrieved from underwater including at deep ocean levels, and the water pressure from any applicable depths will not penetrate the ship. For Self-Coupling Piping Systems, the Torpedo Pipe Storage System can be part of a robotic pipe alignment and coupling system that fetches each piece of pipe, and the couples the multiple pieces of pipe at the entrance / exit point of the vessel. The robotic system on the ship can also couple the outgoing piping to the applicable internal plumbing systems that pertain to the piping, such that the systems of pipe retrieval, robotic alignment and self-coupling, and the self-installation, all work together and should be able to install all of the piping automatically without the need for human intervention. This process works in the same way if the piping needs to be pulled back up and put away, such that the systems work together to move the pieces of the piping back into the ship, passing through multiple airlocks to isolate each piece of piping, and then pushing the piping back into storage.
