How to ensure the safety of tourist submarines?

The materials and workmanship used in building tourist submarines must strictly comply with prescribed standards. The design of tourist submarines must fully consider emergency performance. When an accident occurs underwater, the submarine can immediately throw away the ballast weight, or quickly discharge the ballast water in the ballast water tank, or use both methods at the same time, so that the tourist submarine in a dangerous state underwater can quickly Come up to the surface. Tourist submarines are equipped with very complete life-saving devices and life support facilities. Generally, the spare oxygen and other energy sources carried by large or medium-sized tourist submarines can allow the tourist submarines to stay underwater for 3 days and nights, ensuring that tourist submarines that are unable to float on their own can be rescued by the outside world. A life jacket is provided under or behind each passenger's seat for passengers to wear to escape if the tourist submarine crashes. Each tourist submarine is equipped with high-performance fire-fighting equipment inside, and a sufficient number of emergency breathing masks are also provided on board. Generally, large and medium-sized tourist submarines have supporting surface support ships and surface viewing ships. The surface support ship is equipped with complete salvage, lifesaving, rescue and communication equipment, and can carry out various rescue activities for the wrecked tourist submarine.

Over the past thirty years, nearly one hundred tourist submarines have been built around the world and put into commercial operation.
