§ 10 Installations, systems and equipment

Installations, systems and equipment shall be designed in the most robust and simple manner possible and such that
  1. the possibility for human error is limited,
  2. they can be operated, tested and maintained without risk to the personnel and with the lowest possible risk of pollution,
  3. they are suitable for use and able to withstand the loads/actions they can be exposed to during operation.
Installations, systems and equipment shall be marked so as to facilitate safe operation and proper maintenance.
Section last changed: 01 January 2013

Regulations laid down by the Ministry of Labour and Social Affairs 6 December 2011, pursuant to the Working Environment Act, and entering into force 1 January 2013, including Regulations relating to conduct of work, use of work equipment and appurtenant technical requirements (Conduct of Work Regulations), contain further provisions on certain types of work equipment which is also used in the petroleum activities. Clarification of the scope is directly evident from the individual regulations. In addition, reference is made to the lawmirror (in Norwegian only) of the Norwegian Labour Inspection Authority, in which the requirement of the regulations that are being repealed upon entering into force of the new regulations in pursuance of the Working Environment Act, are included.
With regard to the design of installations, systems and equipment, the following standards should be used in the area of health, working environment and safety:
  1. NORSOK D-001 and D-002 for facilities used in drilling and well activities,
  2. NORSOK L-002 and L-004 for pipes and valves,
  3. NORSOK P-002 for process facilities,
  4. NORSOK R-001 for mechanical equipment,
  5. NORSOK R-002 for lifting equipment,
  6. NORSOK S-002 chapter 5 and A.12 in Annex A for machines,
  7. NORSOK Z-015 for temporary equipment,
  8. NORSOK U-100 and U-101 for diving facilities and breathing equipment,
  9. NORSOK U-001 and ISO 13628 for subsea facilities,
  10. IMCA/AODC 035 for electrical installations for use under water,
  11. IEC 61892 for electrical installations and electrical equipment,
  12. NS-EN ISO 11064 as regards human error.
The NS-EN ISO 20815standard can be used for the design of installations, systems and equipment with regard to regularity and reliability.
For installations, systems and equipment on mobile facilities that are registered in a national ship register, the following standards may be used as alternatives in the area of health, working environment and safety:
  1. DNVGL-OS-D101 for marine machinery, pipe systems and mechanical equipment,
  2. DNVGL-OS-D201 for electrical systems and equipment, with the exception of production facilities,
  3. DNVGL-OS-D202 for instrumentation and control systems, with the exception of production facilities,
  4. DNVGL-OS-E101 for facilities used in drilling and well activities.
In order to fulfil the requirement regarding markings as mentioned in the second subsection, the NORSOK Z-DP-002 standard should be used, with the following addition: main components in the installations should be marked with function, and pipe systems should be marked with the relevant fluid and flow direction.
