General Electrical Standards
11.

(b) tested for impact at -35°C and bending at -40°C in accordance with Canadian Standards Association Standard C22.2 No. 0.3-M1985, Test Methods for Electrical Wires and Cables.
(3) Where a primary or secondary distribution system for power, heating or lighting, with no connection to earth, is used on an installation, a device capable of continuously monitoring the insulation level to earth and of giving an audible or visual indication of abnormally low insulation values shall be provided.
(4) The primary source of electrical power on every installation shall
(a) include at least two power plants;
(b) be capable of supporting all normal operations without recourse to the emergency source of electrical power required by section 12; and
(c) if one of the power plants is out of operation, be capable of supporting all operations except drilling and production operations.
(5) The primary circuits from the power plant serving an installation shall be equipped with at least two manual shut-off switches, each at a different location.
Emergency Electrical Power
12. (1) Every installation shall have an emergency source of electrical power that is independent of the primary source of electrical power and that is capable of supplying electrical power sufficient to operate, for at least twenty-four hours, the following equipment:
(a) all lights referred to in subsection (2);
(b) all gas detection and alarm systems;
(c) all fire detection and alarm systems;
(d) all firefighting systems except any fire pump that is driven by a liquid fuelled combustion engine;
(e) the general alarm system and all internal communication systems;
(f) the emergency shut-down system referred to in section 18;
(g) all lifesaving systems;
(h) all navigation lights, sound signal systems and illuminated markings, that are required by section 21;
(i) all radio communication equipment necessary to comply with the contingency plans referred to in section 43;
(j) on a mobile platform, the main ballast control system, one ballast pump for each individual ballast system and one bilge pump for each individual bilge system;
(k) on a column-stabilized mobile platform, the secondary ballast control system;
(l) all equipment necessary to secure the production or drilling operations in progress at any one time in a safe manner, including a well disconnect system;
(m) if a pumping system is required under paragraph (l), one pump that is not driven by an internal combustion engine that has sufficient capacity to kill any well on the installation;
(n) any blow-out prevention system; and
(o) any manned diving equipment dependent on an electrical supply.
(2) Every installation shall be equipped with lights supplied by the emergency source of power described in subsection (1), in the following locations:
(a) every embarkation station on deck and over sides;
(b) every escape route and area containing escape route markings;
(c) all service corridors and corridors in accommodation areas, and all stairways, exits and personnel lift cars;
(d) all machinery spaces and main generating stations;
(e) the control station and all control points;
(f) all spaces from which the drilling and production operations are controlled and at which controls of machinery essential for the performance of those operations and devices for the emergency shutdown of the power plant are located;
(g) the stowage positions for firefighting equipment;
(h) each sprinkler pump and fire pump and each ballast and bilge pump, referred to in paragraph (1)(j), and the starting position for each pump;
(i) every helicopter landing deck and every obstacle marker on that deck; and
(j) the radio room.
(3) Where the emergency source of electrical power required by subsection (1) is a mechanically driven generator, the installation shall be provided with
(a) a transitional source of electrical power, unless the generator will automatically start and supply the power required by subsection (1) in less than 45 seconds from the time the primary source of electrical power fails; and
(b) a self-contained battery system designed to supply sufficient power, automatically on failure or shutdown of both the primary and the emergency sources of electrical power, to operate, for a period of at least one hour the equipment described in subparagraphs (i) and (ii) and, for a period of at least four days, the equipment described in subparagraph (iii):
(i) the lights located in every emergency exit route, at every escape route, in every machinery space, the control station and every emergency assembly room and at every launching station of the lifesaving system,
(ii) the internal communication system and the general alarm system, and
(iii) the navigation lights, sound signal systems and illuminated markings referred to in section 21.
(4) The battery system referred to in paragraph (3)(b) shall be capable of returning to the trickle charge state on restoration of the primary or emergency source of electrical power.
(5) The emergency source of electrical power required by subsection (1) shall, for a floating platform, be designed to function at full rated power when the installation is upright and when it is at any inclination up to a maximum angle of
(a) 22½ degrees about the longitudinal axis and 10 degrees about the transverse axis, in the case of a surface mobile platform;
(b) 25 degrees in any direction, in the case of a column- stabilized mobile platform; and
(c) 15 degrees in any direction, in the case of a self-elevating platform.
(6) The location of the emergency source of electrical power and associated fuel storage, the transitional source of power, if any, and the emergency switchboard on an installation shall be
(a) readily accessible from an open deck space;
(b) segregated by class A-60 divisions, as defined in subsection 23(1), from any space containing the main source of electrical power or the internal combustion engines;
(c) outside any hazardous area; and
(d) for a floating platform, located above the waterline that would exist if the platform were in a damaged condition and in a space outside any part of the platform if it were in that damaged condition.
(7) The emergency source of electrical power required by subsection (1) shall be designed to supply electrical power automatically, on failure of the primary source of electrical power, to a switchboard that is designed to direct the power to the equipment listed in that subsection.
