Equipment placed in protective rooms, should deactivate automatically on detection of gas in the room, with the added possibility of manual deactivation. VHF stations in lifeboats or MOB boats should be designed and located so that they can be used at the same time as the boats are manoeuvred with the engine at maximum revolutions. Guidelines regarding the facilities regulations.

Definitions and abbreviations set out in the Framework Dnnv are not repeated in these regulations. On a subsea facility, the subsea pipeline normally terminates at the connection to a christmas tree or wing valve.

Section 10 of the Framework Regulationsthe party responsible shall prepare and retain material and information necessary to ensure and document that the activities are planned and conducted in a prudent manner, and this may be required to be submitted to the authorities.

The flame spread and smoke development qualities of the materials should be considered when textiles or surface treatment with paint or other coating is used. Petroleum Safety Authority Norway. Control actuators, edition 1,NS-EN Re Section 77 EMC. Section 21 of the Management Regulations. Norwegian Food Safety Authority. The requirement related to stopping, isolation and partitioning as mentioned in the third subsection, means that the following valves normally will be emergency shutdown valves: In cases where the party responsible has dn to apply older technical requirements for a facility, questions may arise over time as to how the technical condition of the facility compares with today’s prudent standard, cf.

Control actuators, edition 1. In living quarters, electrical installations oe be constructed of halon-free materials. For the design of alarm systems, refer to Section 34a on control and monitoring system. The requirement relating to protection against electric shock in the event of errors as mentioned in litera b, entails that quick, automatic disconnection of the power supply shall be provided when a failure arises that can lead to a dangerous flow of current for personnel that unintentionally come into contact with exposed parts of the installation.


Re Section 39 Ballast system. Re Section 54 Christmas tree and wellhead. The two maritime VHF radios with DSC should be located in separate rooms so that they cannot be made inoperable by a single incident.

In order to fulfil the requirements for design and siting referred to in the fourth subsection, the facility should be designed so that the potential for and consequences of accidents are reduced.

Examples of methods for the determination of safety integrity levels, Part 6: Storting White Paper 25 The Ow environmental policy and the state of the environment in Norway relating to reduction of emissions and discharges, litera d: For mobile facilities that are not production facilities, and that are registered in a national ships’ register, DNV-OS-A Chapter 2, Paragraphs 3, 6 and 7 can be used as an alternative.

General principles for design.


The firefighting equipment for the diving facility should cover the entire facility, and have capacity to also put out fires that may arise inside the chambers. Risks as mentioned in the second subsection, may include accumulation of flammable gases, risk of increased explosion pressure and potential reduced access for firefighting. Heat release rate Cone Calorimeter methodedition 2. Cnv Section 59 Health department When stipulating fire resistance for load-bearing structures, varying material utilisation can be taken into account.

Well testing as mentioned in the third subsection, means flow during formation testing, test production, clean-up and stimulation of the well. The requirement relating to design as mentioned in the first subsection, shall be seen in the context of Chapter II of the Framework Regulations. Examples of conflicting requirements are; pressure definitions and system test pressure requirements.

New type as mentioned in the third subsection, means a type that deviates materially from previous structural solutions, i. This standard requires that the manufacture of line pipe and construction is performed to this standard. References B Applicability The following standards include provisions which, through reference in the text constitute provisions of this offshore standard.

There should be emergency lighting in those areas where personnel can be located in a hazard and accident situation. Following delegation of authority from the Norwegian Food Safety Authority, the County Governor of Rogaland supervises compliance with the provision relating to food, water supply and drinking water in the petroleum activities.

It is important to identify differences between these at an early stage and assess these. Sections 1 and 2 of the Machinery Regulations stipulate the scope of the regulations and which equipment is covered by the Machinery Regulations.

The standard of hygiene as mentioned in the second subsection, should particularly be maintained in cabins, day rooms, the health department and areas where food is stored, prepared and served, cf. Re Section 30 Fire divisions Section 42 Materials for action against acute pollution.

This means that the party responsible can choose to use technical requirements in regulations that applied on and after the time of the PDO approval.


ISO Fire-resistance tests — Elements of building construction, Part 13 and 4 through 7. For mobile facilities, this standard should be used for vibrations in the 5—80 Hz frequency range. Moreover, the dimensioning extent of the damage should be based on an assessment of possible fault modes.

The connection piece is part of the subsea pipeline. Requirements regarding surface quality should be specified in connection with carrying out non-destructive testing of forged and cast goods. The need to qualify new technology should also be taken into account, cf.
