PART IGeneral Requirements

General

 For the purpose of ensuring the safety of an installation, no operator shall use the installation unless the equipment on the installation is arranged in accordance with these Regulations to

  • (a) provide for the safety of personnel;

  • (b) minimize damage to the environment; and

  • (c) enable easy access to the equipment.

Quality Assurance

  •  (1) Every new installation shall be designed, constructed, installed and commissioned in accordance with a quality assurance program that complies with subsection (2) and that is selected in accordance with Canadian Standards Association CAN3-Z299.0-86, Guide for Selecting and Implementing the CAN3-Z299-85 Quality Program Standards.

  • (2) A quality assurance program shall be developed in accordance with

    • (a) Canadian Standards Association CAN3-Z299.l-85, Quality Assurance Program — Category 1;

    • (b) Canadian Standards Association CAN3-Z299.2-85, Quality Control Program — Category 2;

    • (c) Canadian Standards Association CAN3-Z299.3-85, Quality Verification Program — Category 3; and

    • (d) Canadian Standards Association CAN3-Z299.4-85, Inspection Program — Category 4.

Helicopter Deck

  •  (1) Every helicopter deck or facility that forms part of an offshore installation shall

    • (a) conform to Transport Canada TP 4414, Guidelines Respecting Helicopter Facilities on Ships; and

    • (b) be equipped so that any fuel stored on or adjacent to the helicopter deck or to the accommodation areas

      • (i) can be jettisoned by action taken at another location on the installation, or

      • (ii) is protected against damage or impact.

  • (2) Every helicopter deck that forms part of an offshore installation shall be in a location that is readily accessible to and from the dependent personnel accommodation of the installation.

  • (3) Every helicopter facility that forms part of an onshore installation shall conform to Transport Canada TP2586E, Heliport and Helideck Standards and Recommended Practices.

Facilities for Inspection and Maintenance

 An offshore installation shall be designed and equipped in such a manner as to allow for the monitoring, maintenance and periodic inspection of the installation, including

  • (a) clear marking and identification of the areas to be inspected;

  • (b) provision for safe access to and adequate inspection space for the areas to be inspected;

  • (c) space for the storage and operation of diving equipment;

  • (d) means to facilitate the work of divers, where inspection by divers is required;

  • (e) means to assist maintenance personnel, including those doing underwater maintenance, to perform their work safely and effectively; and

  • (f) in the case of a mobile offshore platform that is not intended to be periodically drydocked, means to facilitate on- location inspection of the hull.

Secondary Structures and Fittings

 All decks, deckhouses, skids, modules and other structures located or installed on an offshore installation shall be capable of withstanding all the loads and forces to which they will be subjected, as determined in accordance with section 45.

Arrangements of Materials and Equipment

  •  (1) In this section

    flame-type equipment

    flame-type equipment means any electric or fired heating equipment that uses an open flame, electric arc or element, and includes a space heater, a torch, a heated process vessel, a boiler, an electric arc or an open flame welder, or an open element electric heater or appliance; (équipement de type à flamme)

    process vessel

    process vessel means a heater, dehydrator, separator, treater or vessel used in the processing or treatment of produced gas or oil. (récipient de fabrication)

  • (2) No person shall create or cause to be created any unprotected flame or source of ignition within 50 m of a well, an oil storage tank or other source of ignitable vapour.

  • (3) No oil storage tank shall be placed or remain within 50 m of an onshore well.

  • (4) No flame-type equipment shall be placed or operated within 25 m of a well, an oil storage tank or other source of ignitable vapour, except

    • (a) where the well is

      • (i) a water supply well, or

      • (ii) a water injection well equipped with a suitable packer and with the surface casing annulus vented outside any building; or

    • (b) where emergency work requires the use of flame-type equipment and the wellhead valves and blow-out preventer, if any, are closed.

  • (5) No flame-type equipment shall be placed or operated within 25 m of a process vessel, unless the flame type equipment is fitted with an adequate flame arrester.

  • (6) No flame-type equipment shall be located in the same building as a process vessel or other source of ignitable vapour, unless

    • (a) the air intakes and flues of all burners are located outside the building;

    • (b) relief valves, safety heads and other sources of ignitable vapours are vented outside the building and discharged above roof level; and

    • (c) the building is adequately cross-ventilated.

  • (7) All process vessels and equipment from which ignitable vapour may issue shall be vented to the atmosphere, and all vent lines from every storage tank that is vented to flare pits or flare stacks shall be provided with flame arresters or other equivalent safety devices.

  • (8) An exhaust pipe from an internal combustion engine located within 25 m of a well, a process vessel, an oil storage tank or other source of ignitable vapour shall be constructed so that

    • (a) any emergence of flame along its length or at its end is prevented; and

    • (b) the end is at least 6 m from the vertical centre line of the well projected upward and shall be directed away from the well.

  • (9) All equipment at or near a well, a process vessel, an oil storage tank or other source of ignitable vapour shall be constructed in accordance with Part I of the Canadian Electrical Code Part I and the Oil and Gas Occupational Health and Safety Regulations.

Access to Hazardous Areas

  •  (1) Subject to subsection (2), there shall not be direct access or any opening in an installation between

    • (a) a non-hazardous area and a hazardous area; or

    • (b) a Class I, Division 2, hazardous area and a Class I, Division 1, hazardous area.

  • (2) Subject to subsections (3) to (5), an enclosed area that has direct access to, and that is classified as less hazardous than, a Class I, Division 1, hazardous area or a Class I, Division 2, hazardous area shall be considered to have the same classification as the area to which it has direct access.

  • (3) An enclosed area that has direct access to a Class I, Division 1, area shall be considered to be a Class I, Division 2, hazardous area if

    • (a) the access is fitted with a self-closing gastight door that opens into the enclosed area; and

    • (b) when the door is open, the air flows from the enclosed area into the Class I, Division 1, hazardous area.

  • (4) An enclosed area shall not be considered to be a hazardous area because of its direct access to a Class I, Division 2, hazardous area if

    • (a) the access is fitted with a self-closing gastight door that opens into the enclosed area; and

    • (b) when the door is open, the air flows from the enclosed area into the Class I, Division 2, hazardous area.

  • (5) An enclosed area shall not be considered to be a hazardous area because of its direct access to a Class I, Division 1, hazardous area if

    • (a) the access is fitted with self-closing gastight doors forming an air-lock; and

    • (b) the enclosed area is maintained at a pressure that is higher than the pressure maintained in the Class I, Division 1, hazardous area.

  • (6) Piping systems on an installation shall be designed to preclude direct communications between hazardous areas of different classifications and between hazardous and non-hazardous areas.
