This entails that an assessment has to be made of existing facilities to determine whether the facility fulfils the requirements of the regulations. Re Section 57 Pipeline systems In order to fulfil the requirements regarding noise in the individual areas as mentioned in the second subsection, the NORSOK S standard Chapter 5.

Design to handle controlled well flow as mentioned in the first subsection, means.

General principles for design, NS-EN 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: The test methods in the following standards should be used for penetrations: For mobile facilities that are not production facilities and that are registered in a national shipping register, DNVGL-OS-A can be used as an alternative in the area covered by the standard.

Fire divisions with coated or sprayed-on fire protection material that does not fulfil the requirements for inflammability, may be used if an overall assessment indicates that this is dnvv from a safety point of view, cf.

Re Section 8 Safety functions 7. As regards water breakthrough in floating facilities, see Sections 39 and It is important to identify differences between these at an early stage and assess these.
