Section last changed: 01 January 2014
Safety functions as mentioned in the first subsection, are included as barriers against hazard and accident situations as mentioned in Section 5, and Sections 4 and 5 of the Management Regulations.
Safety functions can be divided into active and passive functions.
The design of active safety functions as mentioned in the first subsection, should be based on the standards NORSOK S-001, NS-EN ISO 13702, IEC 61508 and ISO 13849. The Norwegian Oil and Gas’ Guideline No. 070 should be used in addition.
To ensure that the active safety functions are always able to function as mentioned in the first subsection, they should be designed so that they can be tested and maintained without impairing the performance. For disconnection of safety functions, see Section 26 of the Activities Regulations.
In order to stipulate the performance for the safety functions as mentioned in the second subsection, the IEC 61508 standard and Norwegian Oil and Gas’ Guideline No. 070 should be used where electrical, electronic and programmable electronic systems are used in the structure of the functions.
In order to fulfil the requirement for available status as mentioned in the third subsection, the NORSOK I- 002 standard, Chapter 4 should be used.
