Canada–Nova Scotia Offshore Area Petroleum Operations Framework Regulations — 126
Emergency electrical power supply 126 (1) An operator must ensure that an installation has an emergency electrical power supply that is independent of the main electrical power supply such that the following systems and equipment continue to function in the event of a failure of the main electrical power supply: (a) lights at (i) all embarkation and debarkation stations and evacuation points, (ii) all escape routes, temporary safe refuges, service corridors, accommodations area corridors, stairways, exits and personnel lift cars, (iii) all control centres, control stations and areas from which the communication system referred to in section 129 is controlled, (iv) spaces from which drilling or production equipment, including any equipment that is critical to that equipment’s operation, is controlled, (v) spaces where equipment that is related to the emergency shutdown system referred to in section 133 and to the power plants referred to in paragraph 122 (4)(b) is located, (vi) areas where emergency response equipment is stored, and (vii) aircraft landing areas and the location of any obstacle to take-off and landing; (b) hazard detection systems, including the central monitoring system referred to in section 169 and the fire and gas detection system referred to in section 132 ; (c) emergency response and life-saving systems, including life-saving appliances that require electrical power; (d) the communication system referred to in section 129 ; (e) the emergency shutdown system referred to in section 133 ; (f) the lights and sound-signalling appliances referred to in section 127 ; (g) in the case of a floating platform, the pumps and powered watertight doors and hatches that are necessary to stabilize the installation, having regard to the failure modes and effects analysis referred to in subsection 144 (5); (h) in the case of a column-stabilized mobile offshore platform, the ballast systems referred to in section 144 ; (i) the systems and equipment that are necessary to safely suspend at any time drilling or production that is in progress, including (i) blowout prevention systems, including the blowout preventer referred to in subsection 68 (5), (ii) any disconnectable mooring system referred to in section 148 , (iii) any disconnect system referred to in section 150 , and (iv) pumping systems; and (j) any other system or equipment that requires electrical power and that is referred to in the operator’s safety plan referred to in section 9 or its contingency plan referred to in section 11 . Mechanically driven generator (2) If the emergency electrical power supply is a mechanically driven generator, the operator must ensure that (a) the installation is equipped with a transitional source of electrical power, unless the generator will automatically start and supply the necessary power in less than 45 seconds from the time the main electrical power supply fails; (b) the installation is equipped with a self-contained battery system that is designed, on failure or shutdown of both the main electrical power supply and the emergency electrical power supply, to automatically supply sufficient power to operate (i) for a period of at least one hour, the lights that are located in any emergency exit route, any escape route, any space where equipment incorporating an internal combustion engine, gas turbine, electric motor, generator, pump or compressor is found, any control centre and any emergency assembly room and at every launching station of life-saving appliances, (ii) for a period of at least one hour, the communication system referred to in section 129 and the general alarm system referred to in section 130 , and (iii) for a period of at least four days, the lights and sound-signalling appliances referred to in section 127 ; and (c) the mechanically driven generator has redundancy in its starting capabilities and a dedicated fuel source. Design and maintenance (3) The operator must ensure that the emergency electrical power supply
