Definitions and abbreviated forms that follow from superior and equal regulations are not repeated in these guidelines. These comments elaborate or provide additional information in relation to the definitions as mentioned in this section.

Fire divisions – Class A and Class H:

For standardised fire tests the ISO 834 standard should be used.

Simpler facilities without overnight stay possiblities:

Integrated development concepts as mentioned under simpler facilities without overnight stay possibilities litera c, means facilities with gangway connections. The simpler facility may, nevertheless, be linked to other facilities by a pipeline system.

Not constituting a danger to other facilities as mentioned under simpler facilities without overnight stay possibilities litera c, means, inter alia, that a fire on the facility does not jeopardise the safety of other facilities, e.g. through the possibility of the fire spreading or thermal stress.

Pipeline systems:

On a subsea facility, the subsea pipeline normally ends in a connection to a christmastree or wing valve. The christmastree is not considered to be a part of the pipeline system.

On a subsea facility where the above definition cannot be employed, the subsea pipeline ends at the connection to the subsea facility. The connection piece is a part of the subsea pipeline.

Subsea pipelines and risers up to and including the lock for launching or receiving tools for internal maintenance (including inspection), with associated equipment, are considered to belong to the pipeline system. If such a lock has not been installed, the pipeline system is considered to extend to the first automatic shutdown valve above water.

In order to fulfil the requirements to living quarters as mentioned in the first paragraph, the NORSOK standards C-001 revision 3, C-002 revision 3, S-001 revision 4 and S-002 revision 4 should be used with the following additions:

a) the capacity requirement as mentioned in the first paragraph, means that the living quarters are dimensioned with sufficient margins to avoid bed scarcity during peak manning,

b) the living quarters should be designed so that personnel can sleep undisturbed and be assured of satisfactory restitution.

For mobile facilities that are registered in a national ship’s register, the Norwegian Maritime Directorate’s regulations 17 December 1986 No. 2318 concerning construction and outfitting of the living quarter on mobile offshore units, last amended 11 April 2003, Sections 6, 7, 8, 12, 13, 14, 15, 17 and 18 may be used as an alternative to the standards NORSOK C-001 revision 3 and C-002 revision 3, with the following additions:

a) the additions as mentioned in the first paragraph,

b) bunks should be replaced with beds on the floor, cf. Section 19 on ergonomic design.

The requirements as mentioned in the first paragraph, also apply to simpler facilities with overnight stay possibilities, but consideration may be given to whether

a) the dining hall should be included in the total recreation area,

b) adaptation of kitchen and washing-up areas should be in proportion to the need on the facility,

c) the laundry room can be omitted,

d) the dedicated health department can be omitted.

If a dedicated health department is omitted, there should be adequate area and equipment on the facility to cover the need for first aid until the helicopter arrives.

The standard of hygiene as mentioned in the second paragraph, should particularly be maintained in cabins, day rooms, the health department and areas where food is stored, prepared and served, see Section 62 on supply of food products and drinking water.

For facilities where no permanent manning is planned, consideration should be given to whether living quarters should be built, or emergency quarters. These evaluations shall include, as a minimum,

a) anticipated scope of work and work organisation,

b) risk related to transportation and stay on the facility,

c) working environment matters,

d) need for restitution and rest,

e) hygienic conditions.

Re Section 60
Health department

If facilities are connected by gangways, the requirement as mentioned in the first paragraph, implies that at least one of the facilities shall have a health department.

In order to fulfil the requirements to a health department as mentioned in the first paragraph, the NORSOK standard C-001 revision 3 Chapter 7.17 should be used with the following additions: the health department should be located such that it to the smallest extent possible is exposed to noise and vibrations, and such that stretcher transport to the health department of sick or injured personnel can be accomplished in a prudent manner.

For mobile facilities that are registered in a national ship’s register, the Norwegian Maritime Directorate’s regulations 17 December 1986 No. 2318 concerning construction and outfitting of the living quarter on mobile offshore units, last amended 11 April 2003, Section 16 may be used as an alternative to the standard NORSOK C-001 revision 3, with the same additions as mentioned in the second paragraph.

The health department's equipment should be assessed on the basis of the defined situations of accident and hazard as mentioned in the Management Regulations Section 15 on quantitative risk analyses and emergency preparedness analyses.

Equipment as mentioned in the second paragraph, encompasses, inter alia, medications and first aid equipment, stretchers and medical rescue equipment.

Re Section 61
Emergency unit

The emergency unit will normally be a room that has another primary function, but that can quickly be converted into an emergency unit if needed.

In order to fulfil the requirements to the emergency unit, the NORSOK C-001 revision 3 standard Chapter 7.17 should be used.

Re Section 62
Supply of food and drinking water

The requirement to design as mentioned in the second paragraph, implies that technical solutions for food and drinking water supply shall satisfy the provisions in the food regulations for land-based activities, as well as the Regulations relating to water supply and drinking water. In addition, the technical solutions should be based on recognised methods to the extent possible.

Reference is also made to the guidelines to the Activities Regulation Section 11 on food and drinking water.

Reference is also made to Chapter III in the Regulations 4 September 1987 concerning potable water system and potable water supply on mobile offshore units, issued by the Norwegian Maritime Directorate pursuant to the Seaworthiness Act. By adhering to the somewhat more detailed provisions, etc. stipulated in the latter regulations, one will normally also fulfil the Facilities Regulations' provisions on drinking water systems. The Norwegian Maritime Directorate's regulationsare not legally binding, however, with respect to anything other than facilities that are or will be registered in a Norwegian ship's register, cf. Section 2 of the regulations. The provisions of the Facilities Regulations may thus also be fulfilled by selecting other means than those given in the regulations of the Norwegian Maritime Directorate.

Reference is also made to the following standard: NORSOK P-100 Chapter 22. It is assumed that the NORSOK standard will be supplemented with the National Institute of Public Health's guideline material for design of drinking water systems.

The Norwegian Board of Health, or anyone authorised by the Board, also carries out supervision in accordance with the Framework Regulations to ensure that the provision on food, water supply and drinking water is fulfilled in the petroleum activities.

With regard to exhaust ducts from reconditioning plants in drilling fluid systems, see Section 50 on drilling fluid systems.

Re Section 70
Lifting appliances and lifting gear

The Machinery Regulations apply to design, manufacture and sale of lifting appliances and lifting gear for use on permanently placed facilities. The machinery regulations are expanded on in harnonised standards, including the EN 13852-1 for offshore cranes. The standard EN 13852-1 should also be used on mobile facilities that are registered in a national ship’s register. With regard to evaluation of the technical condition of cranes on existing mobile facilities that will be put into service on the Norwegian continental shelf, reference is made to the Norwegian Shipowners’ Association’s Guidelines for implementation of EN 13852-1 on existing offshore cranes on mobile offshore units.

The requirement as mentioned in the first paragraph second sentence, continues the current law in the regulations under the Petroleum Act and applies only to the safety aspects, not the health and environment aspects.

In order to fulfil the requirement to remote operation as mentioned in the third paragraph, the NORSOK D-001 standard Chapter 5.4 and OLF/NR guideline No. 081 revision 2 should be used, with the following addition:

lifting equipment should have independent safety assemblies and be hung off and stored in such a way that the equipment is secure in the event of heeling, and that the danger of falling objects is limited.

Snubbing units as mentioned in the last paragraph, means mobile units that are installed so that forces are transferred directly to the wellhead. For snubbing units, the requirement will be made applicable to the extent that equipment to be used with such units, has been developed and tested.

For lifting appliances and lifting gear on the drill floor of mobile facilities that are registered in a national ship's register, the ISO 13535 standard and relevant parts of the DNV OS-E101 standard may be used as an alternative to the standard NORSOK D-001.

For remote operation of pipes and work strings on mobile facilities that are registered in a national ship's register, the DNV OS-E101 chapter 2, section 5, F 100-400 may be used as an alternative to the standard NORSOK D-001 chapter 5.4.

Re Section 71
Helicopter decks

In order to fulfil the requirement to helicopter decks as mentioned in the first paragraph, the NORSOK C-004 standard may be used as an additional document. The requirements in the regulations of the Civil Aviation Authority shall be complied with in all cases.

For design of helicopter decks, the NORSOK S-001 standard revision 4 Chapter 20.4.9 should be used with the following addition:

for facilities where there are particular problems related to take-off and landing, consideration should be given to such problems when determining the design and location of the helicopter deck.

Re Section 72
Marking of facilities

In agreement with the Coast Directorate, the following provisions shall be used for marking of facilities as mentioned in the first paragraph: IALA Recommendation on the marking of offshore structures (IALA Recommendation O-114 May 1998) with the following modifications and additions:

Re O-114 Section 2.3.1

The main light shall have a nominal range of 15 nautical miles.

The horizontal extremities of the facility, with the exception of extremities that are marked with a main light, shall, in case it is considered to be necessary, be marked with a red light (“subsidiary light”). This light shall have the same code/character as the main light and have a nominal range of 3 nautical miles. Subsidiary lights shall be synchronised, but not necessarily synchronised with the main light.

As regards calculation of the light intensity required to achieve the given ranges, reference is made to the Recommendation on the Photometri of Marine Aids to Navigation Signal Lights (IALA Recommendation E-122 June 2001).

Re O-114 Section 2.3.3

Use of sound signals will not be ordered. Earlier orders relating to the use of sound signals are revoked.

Re O-114 Section 2.3.6

Only in exceptional cases will it be of relevance to use floating marking equipment for traditional marking of facilities in the petroleum activities.

Re O-114 Section 2.4

In addition the equipment mentioned, it may also be of relevance to use AIS as additional marking.

It will also be generally required that all marking of facilities in the petroleum activities shall have an availability of 99.8 per cent measured over a three year period (cf. IALA Recommendation O-130 On Categorisation and Availability Objectives for Short Range Aids to Navigation December 2004).

Identification panels

Facilities shall be fitted with identification panels displaying block number, name of field and name of facility, in black letters/ figures 1 meter high on a yellow background. The identification panels shall be so arranged that at least one panel is visible from any direction. The identification panels shall be visible in daylight as well as in darkness.

For requirements to marking of mobile facilities that are registered in a national ship's register, reference is made to the Framework Regulations Section 3 on use of maritime legislation in the petroleum activities.

Re Section 73
Marking of equipment and cargo

This section is a continuation of the former Safety Regulations Section 41.

Re Section 74
Lifts

In order to fulfil the requirement to lifts, harmonised EN standards that are prepared on the basis of the Lift Directive, should be used. The Lift Directive itself is not made appliccable to the petroleum activities. On mobile facilities, the ISO 8383 standard should be used.

Chapter V
IMPLEMENTATION OF EEA LAW

Re Section 75
Simple pressure vessels

This section continues the previous incorporation in the petroleum activities of Council Directive 87/404/EEC relating to simple pressure vessels.

Re Section 76
Personal protective equipment

This section continues the previous incorporation in the petroleum activities of Council Directive 89/686/EEC relating to personal safety equipment. In addition, the changes made in Council Directive 93/95/EEC, have been incorporated.

Re Section 77
Aerosols

This section continues the previous incorporation in the petroleum activities of Council Directive 75/364/EEC relating to aerosols, as well as the adopted changes in Commission Directive 94/1/EEC.

Re Section 78
EMC

This section continues the previous incorporation in the petroleum activities of Council Directive 89/336/EEC and Council Directive 92/31/EEC (electromagnetic compatibility – EMC).

Re Section 79
Ex-equipment

This section no longer applies, hence no comment.

Re Section 80
ATEX

This section continues the previous incorporation in the petroleum activities of Council Directive 94/9/EU relating to equipment and safety systems for use in areas where there is a hazard of explosion (ATEX).

The ATEX Regulations have limited application in the petroleum activities.

See the guidelines to Section 83 on entry into force as regards the transitional arrangement up to 30 June 2003.

Re Section 81
Pressure equipment not comprised by the Facilities Regulations

The purpose of this section is to clarify the relationship to the Regulations 9 June 1999 No. 721 relating to pressure equipment (RPE).

The RPE have limited application in the petroleum activities.

The RPE entered into force on 29 November 1999 with a transitional period up to 29 May 2002. The regulations that applied when the RPE entered into force, will be accepted until 29 May 2002.

Reference is made to the Framework Regulations Section 63 on entry into force and repeal of regulations No. 2, litera o, which states that the Regulations 7 February 1992 No. 151 relating to process and auxiliary facilities in the petroleum activities may be used for pressure equipment covered under the RPE up to 29 May 2002.

In those cases where the RPE do not apply, relevant parts of the Facilities Regulations will apply.

Re Section 82
Machinery and safety components not comprised by the Facilities Regulations

The purpose of this section is to clarify the relationship to the regulations 20 May 2009 No. 544 relating to machinery (the Machinery Regulations).

The Machinery Regulations have limited application in the petroleum activities and do not comprise seagoing vessels and mobile facilities together with machinery on board such vessels or facilities, cf. the Machinery Regulations Section 1, No. 2, litera f. This means that the Machinery Regulations apply to permanently placed facilities, including floating production facilities in permanent positions (in position for the entire life span of the field). As regards these floating production facilities, the Machinery Regulations apply to equipment that is necessary for carrying out drilling and production activities, and that does not have any function in relation to normal maritime activities.

The Machinery Regulations Sections 1 and 2 of stipulate the scope of the regulations and which equipment is comprised by the Machinery Regulations. In those cases where the Machinery Regulations do not apply, relevant parts of the Facilities Regulations will apply.

Chapter VI
ENTRY INTO FORCE

Re Section 83
Entry into force

See the Framework Regulations Section 63 on entry into force and repeal of regulations No. 2 for an overview of which regulations are repealed when these regulations enter into force.

Within the scope of the Pollution Control Act, the complete Facilities Regulations enter into force 1 January 2002. This also applies to existing facilities. This implies that an assessment has to be made of existing facilities to determine whether the facility fulfils the requirements of the regulations. This applies in particular to the requirements in Sections 14, 39, 47, 50, 51, 53, 56 and 68 of the regulations. If the facility does not fulfil the requirements of the regulations, changes must be made to the facilty. If particular reasons so warrant, the NPCA can exempt from requirements in the regulations. This could, for example, be instances where the costs of making changes far exeed the environmental gain. It is not presumed that the regulations’ requirements on account be taken of the external environment, will entail major or costly changes to existing facilities. In many of the requirements, provision is made for making a cost-benefit assessment in relation to that of deciding whether the requirements of the regulations are fulfilled or not. This applies, for example, to Section 39 on open drainage systems.

Sections 3, 4, 5, 9 and 11 say that consideration shall be given to the risk of pollution or environmental risk when selecting materials and when choosing and designing facilities and plants. These provisisons will be of significance in the planning and designing phase, and when modifying plants and facilities. These sections do not require, however, that changes are made to existing plants and facilities.

This Section No. 2 viewed in context with the Framework Regulations Section 63 on entry into force and repeal of regulations, implies that, in the area of health, working environment and safety, it is the technical requirements in the regulations that applied up to the date when these regulations entered into force, that can still be used as a basis.

See also the Framework Regulations Section 63 on entry into force and repeal of regulations No. 2, litera o which stipulates a transitional arrangement for pressure equipment comprised by the Regulations 9 June 1999 No. 721 relating to pressure equipment. See the comments to Section 81 on pressure equipment not comprised by the Facilities Regulations.

The transitional arrangement up to 30 June 2003 for equipment comprised by these regulations Section 80 on ATEX, still applies. This implies that provisions on such equipment in regulations that applied at the time of entry into force of these regulations, may still be used up to 30 June 2003.

Major rebuildings and modifications as mentioned in this Section No. 3, may be the installation of a new module, major interventions in hydrocarbon-carrying systems or major changes in physical barriers. With regard to the use of new standards in such contexts, see the Framework Regulations Section 18 on documentation.

Existing facilities as mentioned in this Section No. 3, means facilities where the plan for development and operation of petroleum deposits (PDO) has been approved according to the Petroleum Act Section 4-2, or where special permission has been given on the basis of plans for installation and operation of facilities for transport and exploitation of petroleum (PIO) according to the Petroleum Act Section 4-3, or facilities that have beenn granted consent to carry out petroleum activities before these regulations entered into force.

For mobile facilities that are registered in a national ship's register, the requirements in the new regulations will apply when a new consent is applied for, see the Framework Regulations Section 63 on entry into force and repeal of regulations. It ensues from the Information Duty Regulations Section 6 on contents of application for consent that, when applying for consent, the operator shall provide an overview of previously granted exceptions for mobile facilities. Previously granted exemptions follow the mobile facility. New operators must, however, evaluate whether it is prudent to operate with the exemptions granted, and whether changed conditions exist that make it necessary to apply for a new exemption, see the Framework Regulations Section 59 on exemptions.
