This NORSOK standard is applicable for preparation and optimisation of maintenance activities for plant systems and equipment including

  • offshore topside systems,
  • sub-sea production systems,
  • oil and gas terminals.

The systems involving the following types of equipment:

  • mechanical equipment;
  • static and rotating equipment;
  • piping;
  • instrumentation;
  • electrical equipment.

Excluded from the scope of this NORSOK standard are

  • load bearing structures,
  • floating structures,
  • risers and pipelines.

In principle, all types of failure modes and failure mechanisms are covered by this NORSOK standard.

This NORSOK standard covers

  • definition of relevant nomenclature,
  • brief description of main work flow related to maintenance and which elements this typically involves,
  • definition of risk model and failure consequence classes,
  • guidelines for consequence classification, including
    - functional breakdown of plants and plant systems in MFs and sub functions,
    - identification of MF and sub function redundancy,
    - assessment of the consequences of loss of MFs and sub functions,
    - assignment of equipment to sub functions and associated consequence classes
    - description of how to establish an initial maintenance programme, and how to update an existing programme,
    - description on how to use the classification in combination with probability for decision making related to prioritising work orders and handling spare parts.
