scope:

General

The requirements in this chapter cover the principles for construction of manned submersibles, equipment, machinery systems, electrical systems, controls and communication, life support systems, rescue systems, additional requirements for tourist services, additional requirements for rescue submersibles including rescue vehicles, launch and recovery system (LARS) and supporting systems aboard the support vessel.

For ambient pressure hulls further requirements may be enforced based on the operational profile.

Autonomous submersibles Submersibles,

which require a relevant support vessel during the mission but are not physically connected to it (e.g. by an umbilical), are regarded as autonomous submersibles.

Non-autonomous submersibles Submersibles,

which are during the mission always physically connected to the relevant support vessel (e.g. by an umbilical), are regarded as non-autonomous submersibles.

Independent submersibles Submersibles,

which are able to operate offshore without support vessel, are regarded as independent submersibles.

Ambient pressure submersibles Submersibles,

which are designed for wet and dry service with the personnel compartment at ambient pressure, are regarded as ambient pressure submersibles.

For further definitions, see Sec.2 [3].
