These rules give technical and procedural requirements for classification of complete diving systems, including the certification of components and materials to be used.
The scope of classification includes:
- certification of system components
- plan approval and survey of the diving system.
These rules do not include vessel specific requirements relevant to diving support vessels, as covered by DNVGL-RU-SHIP.
Notwithstanding the above, these rules do apply to the diving system as installed on vessels with the class notation Diving support vessel as described in DNVGL-RU-SHIP Pt.5 Ch.10
The designer or builder may as an alternative to comply with the requirements given in these rules, submit evidence that the topics covered in these rules are accepted by the national authorities.
National authorities may have requirements in addition to the requirements stipulated in these rules. Compliance with the requirements in these rules will not automatically result in compliance with requirements stipulated by the national authorities.
These rules apply to certification and classification during the design, construction and operation of diving systems.
These rules are intended for diving systems used in the petroleum and natural gas industries. For application in other industries, special considerations may need to be agreed by the parties to the contract and or involved statutory regulators.
Additional requirements for the diving system may be applicable due to the statutory requirements given in certain geographic areas, or onboard ships flying certain flags (see also Sec.2 [2.2]) .
These rules apply to both transferable and permanent installed diving systems as located on and operated from a ship, barge, mobile offshore platform, fixed offshore installation or an onshore site (in the latter case e.g. for training and research purposes).
These rules do not apply to submersibles or atmospheric diving systems (ADS such as JIM and NEWT suits) as these are covered by DNV GL rules for classification: Underwater technology (RU-UWT).
