The Bathysphere is a unique, spherical deep-sea submersible designed by Otis Barton that has no internal power. Instead, it's lowered into the ocean by a cable. Most famously used to conduct dives off the coast of Bermuda in the 1930s. Watson Stillman Hydraulic Machinery Company handled the casting of the original steel Bathysphere, but other manufacturers have cast reproductions.


Designed by the same engineer, the Benthoscope was similar to the Bathysphere. It was built to withstand higher pressure and has been used on record-breaking solo descents to 4,500ft, rather than the 3,000 ft depth of the original Bathysphere. The internal diameter was 1.4m, and it had a wall thickness of 44.5mm.

Deep Submergence Vehicles

Deep Submergence Vehicles are deep-diving crewed submarines that use self-propulsion. Commonly divided into two types: research and rescue vehicles. Research vehicles are used for ocean surveying and exploration, while rescue vehicles are often used to rescue crews of sunken submarines or for installing undersea cables and wiretaps.

Diving Bell

Diving bells are one of the earliest forms of underwater exploration equipment. In modern diving bells, air overpressure and fresh air are supplied through pipes and air pump, filling the rigid chamber with a breathable atmosphere. The most common types are the closed bell and the open bottom wet bell.

Diving Chamber

A diving chamber is typically a small underwater vessel used for sole human occupation. Hyperbaric diving chambers have an entrance that can be sealed to hold internal pressures higher than the ambient, using a pressurized gas system. It can be used for diver training, therapeutic recompression, surface decompression, and saturation diving.

Mini Submarine

Mini submarines are categorized as underwater vehicles that weigh less than 150 tons. Typically operated by one or two crew members, but can hold up to nine people. Little to no onboard accommodation is provided, as they generally partner with larger submersibles that house living accommodation and support staff.


Remotely operated vehicles are tethered underwater devices that are typically operated from nearby floating platforms, ships, or land. They're unoccupied vessels used extensively in deepwater industries, including hydrocarbon extraction, sub-sea development, and sub-sea repair. Most ROVs are equipped with lights and video cameras.


AUVs are autonomous vehicles that travel underwater without being controlled by an operator like an ROV. Vehicles range in size from portable AUVs to 10m length. Many roboticists build AUVs as a hobby, but they are also widely used in commercial, research, wreckage investigations, and military applications.


In 1961, the first semi-submersible vessel was launched by the Blue Water Drilling Company. Semi-submarines are vessels that are capable of diving but cannot fully submerge. Similar in design to a ship, the passenger cabin is usually a few meters below sea level and has large windows that allow observation of the marine environment during the passage.

Personal Submarines

Personal submarines are usually constructed for recreational use. However, they also have some military applications. Widely use in tourism, watersports, and rescue, personal submarines vary in size and diving depth capability. Some may house over 30 people and can submerge for several weeks, while others are built to house just one occupant.
