§ 32 Fire and gas detection system
Facilities shall have a fire and gas detection system that ensures quick and reliable detection of near-fires, fires and gas leaks. The system shall be able to perform the intended functions independently of other systems.
In the event of fire or gas detection, automatic actions shall limit the consequences of the fire or gas leak. The placement of detectors shall be based on relevant scenarios and simulations or tests.

For design of the system as mentioned in the first subsection, the standards NS-EN ISO 13702 with Appendix B.6 and NORSOK S-001 Chapters 13 and 14 should be used.
The requirement for independence as mentioned in the first subsection, entails that the fire and gas detection system comes in addition to systems for management and control and other safety systems. The fire and gas detection system may have an interface with other systems as long as it cannot be adversely affected as a consequence of system failures, failures or isolated incidents in these systems.
The requirement regarding limiting the consequences as mentioned in the second subsection, entails that relevant safety functions are activated, see Sections 33, 36 and 37.
Facilities that are not permanently manned, should also have a dedicated gas detection function for the area around and on the helicopter deck. Detection of gas should be shown by means of a light signal that is visible at a safe distance from the facility.
For mobile facilities that are not production facilities, and that are registered in a national ship register, DNV-OS-D301 Chapter 2, Paragraph 4 can be used as an alternative.
