When preparing the maintenance programme as mentioned in the first subsection, the NORSOK Z-008 standard, the NS-EN ISO 20815 standard Appendix I and the NEK IEC 60300-3-11 standard can be used in the area of health, working environment and safety.
For activities as mentioned in the second and third subsections, recognized standards should be used in the area of health, working environment and safety that ensure that the required functions of land facilities and parts of these facilities, including temporary equipment, are safeguarded in all phases of the lifetime, cf. Section 58. Functions also mean safety functions. For these functions, the requirement relating to maintenance entails that performance shall be ensured at all times, cf. Section 10.
