Application and scope

This standard applies to diving systems for any fixed location. The diving system may thus be 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).

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

The Standard also applies to transferable diving systems as defined in C.

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

This standard primarily applies to 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.

This standard is applicable to various diving systems such as:

a) diving systems with deck decompression chambers and a ladder or basket for deployment of divers

b) for 'open bell' deployment of divers

c) for 'closed bell' deployment of divers and 'bounce-diving techniques

d) 'saturation diving' systems.

This standard is not applicable to submersibles or submarines.

Upon special consideration, part of a submersible may be verified against parts of this standard.

Guidance note:

The above limitation is due to the additional equipment needed for the propulsion and navigation of the submersibles. Some tethered submersibles are simple in nature and may be seen as a closed bell operated in observation mode with an internal pressure equivalent to one atmosphere.

Other submersibles contain a capsule rather like a closed bell. In these cases this standard may be applied upon special consideration and in agreement between the parties.

Tourist submersibles are not included in this standard.

The scope is defined in each section for the various disciplines and may refer to standards that apply to the discipline in general, such as for electrical systems. In these cases this Offshore Standard (OS) only contains requirements that are particular to diving systems, whereas the generic requirements are given in the referred standard or code. The combined requirements shall then constitute the scope.

This section bears impact on all other sections.
