Plans for the submarine were designed by Frenchman Leopold Villaine, and along with Australian gold miner R. W. Nutall, the pair brought the plans to Dunedin. [4] Nutall proposed that the submarine could prospect any part of a river for gold, with equipment to blast rocks, remove obstructions, and sluice the river bed.
Within 30 minutes, a different, non-nuclear civilian construction group began an assignment to bring Guitarro within a half-degree of trim; this entailed adding water to the forward ballast tanks to overcome a reported two-degree up-bow attitude. Until shortly before 20:00, both groups continued to add water, unaware of each other's activities. [1]
Because the H.L. Hunley was made of iron and was submerged for over a hundred years, rust had formed all over the submarine. However, to prevent more rust from forming, the conservators choose to keep the H.L. Hunley submerged in a water tank, instead of exposing it to the oxygen-rich air, until a full conservation plan could be created.

An emergency main ballast tank blow is a procedure used aboard a submarine that forces high-pressure air into its main ballast tanks. The high-pressure air forces ballast water from the tanks, quickly lightening the ship so it can rapidly rise to the surface.
Educational videos of a submarine imploding have racked up millions of views on TikTok amid the search for the missing Titanic submersible in the Atlantic Ocean where ‘debris’ was uncovered ...
The vents of the Redoutable are under the casing. The square openings in the casing are limber holes to facilitate draining the superstructure. In submarine technology a vent is a valve fitted to the top of a submarine's ballast tanks to let air escape from the top of the ballast tank and be replaced by water entering through the opening(s) called "flood ports" or "floods" at the bottom of the ...
A 16th-century Islamic painting depicting Alexander the Great being lowered in a glass submersible. The concept of underwater transport has roots deep in antiquity. There are images of men using hollow sticks to breathe underwater for hunting at the temples at Thebes, and the first known military use occurred during the siege of Syracuse (415–413 BC), where divers cleared obstructions ...
