Safety
ABS classed tourist submarines carry approximately one million passengers each year (for the past 20 years) and have a perfect safety record, making them statistically the world’s safest form of transportation. Poseidon’s undersea resort was designed by U.S. Submarines to meet the structural requirements applicable to a submarine pressure hull; all components of the resort are structurally very strong with a high overall safety factor. Each individual component of the complex will be automatically isolated in the highly unlikely event of a structural breach. Every unit has a safety dome with an entrance hatch where professionally trained divers can enter. Diving staff regularly practice rescue procedures in a purpose–built unit.
Maintainability
With the exception of the central corridor, which is permanently fixed to the structural base of the facility, each individual unit is neutrally buoyant and capable of being removed from the complex–and the water–if necessary. All important systems are shore–based or can be found inside the complex for easy maintenance. Automated viewport cleaning systems remove marine growth from transparent surfaces.
