Application, scope and assumptions

This recommended practice applies to naval rescue submersible systems (hereafter referred to as submersible systems). The submersible system may thus be located on and operated from a ship, barge, mobile platform, fixed installation or an onshore site (in the latter case e.g. for training and research purposes).

Requirements for support vessels are included such as the requirements for stability, floatation and positioning ability.

The design of arrangements, systems and individual components may, alternatively or supplementary to the recommended practice, be based on recognised standards, codes, national regulations and other methods of safety and strength evaluation than specified in the recommended practice. The basis shall be equivalent to the requirements given in this recommended practice.

This recommended practice applies to submersible systems used in naval rescue activities.

For application in other activities, special consideration may need to be agreed by the parties to the contract and or involved statutory regulators.

This recommended practice is applicable to various submersible systems such as:

— submersible systems coupled with deck decompression chambers and for deployment of divers

— Tethered/remotely operated submersibles

— Supported submersibles

— Autonomous submersibles
