DNV DNV-OS-E402 PDF

The scope of this standard is to provide principles, technical requirements, and guidance for surface orientated and saturated diving systems covering:

— design philosophy

— overall system requirements

— requirements to typical diving components

— certification and classification requirements.

The scope of this standard is complementary to the 2023 Diving Code.

The scope is defined in each section and may refer to standards that apply in general, such as for electrical systems. In these cases this document only contains requirements that are particular to diving systems, whereas the generic requirements are given in the referred rules, standard, or code. The combined requirements then constitute the scope.

Requirements for the diving support vessels, such as the requirements for floatation and positioning ability, are not in the scope of this standard and are provided in DNV-RU-SHIP Pt.5 Ch.10.
