Manned submersibles

A manned submersible is a small vehicle which operates underwater, and holds a small crew. The first submersibles were known as ‘bathyscapes’ which were developed in the 1930s

Submersibles are used for research and tourism purposes, as well as in salvage and escape and rescue missions. Submersibles may be used to help when the crew of a submarine is in a DISSUB situation and needs assistance.

These escape and rescue submersibles can ‘mate’ or dock with submarines in order for people and materials to be passed from the submarine to the submersible, and vice versa.

They come in a wide range of shapes and sizes depending on purpose. Some contain video cameras for monitoring the ocean and some have mechanical arms to perform tasks outside the vehicle. Some submersibles have a lock-in-lock-out (LILO) chamber, which allows divers to leave and enter the submersible while it is underwater.

Manned submersibles are not autonomous and rely on a support facility, such as a submarine or surface vessel.

Manned submersibles will require a life-support system, as well as gas monitoring to ensure the crew’s safety.

Gas monitoring in a manned submersible

Gas monitoring needs depend on whether the manned submersible consists of a single compartment or multi-compartments. Multi-compartment submersibles (for example, those with a LILO chamber) would typically use the Sub MKIIIF as a monitoring system. This would monitor O, CO2, temperature and humidity in both the LILO compartment as well as the emergency breathing system.

Single compartment submersibles would typically use a Sub Aspida. The Sub Aspida can also be used as a back-up monitor in a multi-compartment submersible.

Alternatively we have produced bespoke systems to specific customer requirements.
