(a) is connected to at least two pump systems that are situated as far apart as possible; and
(b) when any one of the pump systems required by paragraph (a) is out of operation,
(i) is capable of delivering at least one jet simultaneously from each of any two fire hydrants through the hoses and nozzles, at a pressure at the hydrants of at least 350 kPa,
(ii) is capable of delivering water at a sufficient pressure and quantity so that the aggregate capacity of the pump systems that are still operating is not less than 120 m3/hour when the pump systems are delivering water to the fire hydrants, and
(iii) is capable of maintaining a pressure of at least 700 kPa to any foam system protecting the helicopter deck.
(3) The number and position of the fire hydrants in the fire hydrant system shall be such that water from any two hydrants, one of which is fitted with only a single length of fire hose and the other of which is fitted with one or two lengths of fire hose, can reach every part of the installation where a fire may occur.
(4) Each fire hydrant in the fire hydrant system shall be provided with a hose that
Water Deluge and Water Monitor Systems in Areas with Petroleum
- water deluge system
water deluge system means a system capable of deluging a space with water from fixed heads; (système déluge)
- water monitor system
water monitor system means a system capable of deluging a space with water from monitors. (système de régulation d’eau)
(2) Every manned offshore production installation shall be equipped with a water deluge system or, in the case of an open space, a water monitor system, for each space in the installation that contains equipment that stores, conveys or processes petroleum not used as fuel on the installation.
(3) The systems required by subsection (2) shall be
(4) Every water deluge system shall
(a) operate automatically in response to a signal from the fire detection system;
(b) be capable of being operated manually from the control station and from locations close to but outside of each space served by it; and
(c) when in operation, automatically activate an audible and visual signal at the fire and gas indicator panel in the control station.
(5) Every water monitor system shall
(a) be capable of being activated manually from the control station and from locations close to but outside of each space served by it;
(b) have sufficient movement in the horizontal and vertical planes to permit the monitor to discharge water into any part of the space served by it;
(c) be capable of being locked in any position; and
(d) be capable of discharging water as a jet or spray.
(6) A water deluge system provided pursuant to subsection (2) shall meet the requirements of National Fire Protection Association 15, Standard for Water Spray Fixed Systems for Fire Protection.
General Requirements for Fire Pump Systems and Water Mains
(2) Every water main referred to in section 24 or 25 shall
(a) be routed clear of hazardous areas as far as practicable;
(b) be arranged in relation to any thermal barriers and structural elements of the installation so as to obtain the maximum protection from damage due to heat;
(c) be equipped with valves that will permit a damaged part of the system to be isolated from the undamaged parts; and
(d) be used solely for the purpose of firefighting.
(3) Every sea suction and source of power for each of the pump systems referred to in section 24 or 25 shall
(a) be designed and arranged to start automatically in response to
(b) be capable of being started manually from the control station and started and stopped manually from a location close to the pump system;
(c) be capable of functioning continuously without attendance for at least 24 hours; and
(d) be designed and arranged so that a fire, explosion or flooding in any one space of the installation will not put more than one pump system out of operation.
(4) When any of the pump systems referred to in section 24 or 25 is started, an audible alarm shall be given automatically at the pump and an audible and visual alarm shall be given automatically at the fire and gas indicator panel in the control station.
(5) Every pump system provided pursuant to section 24 or 25 shall be located in a part of the installation remote from spaces that contain equipment used for storing, conveying or processing petroleum that is not used as fuel on the installation.
Sprinkler System in Accommodation Areas
(a) two dedicated pump systems connected to the water main referred to in section 24 or 25 by way of a lockable screwdown non-return valve that will prevent backflow from the sprinkler system to the water main; or
(b) one dedicated sprinkler pump connected to
(i) the water main referred to in section 24 or 25 by way of a lockable screwdown non-return valve that will prevent backflow from the sprinkler system to the water main, and
(ii) a pressurized fresh water tank having a volume equal to at least twice the volume of water required pursuant to subsection (2) to be supplied for a period of one minute.
(2) The volume of water supplied by the pump systems or pump and fresh water tank described in subsection (1) shall be at a pressure sufficient to ensure, at the level of the highest sprinkler, continuous coverage of at least 280 m2 at the rate of at least 6 L/minute/m2.
(3) The sprinkler pump required by paragraph (1)(b) shall
(4) When the sprinkler system is activated, an audible and visual alarm that shows the location of the activated sprinklers shall be given automatically at the fire and gas indicator panel in the control station.
(5) The sprinkler system shall be designed to prevent the passage of sea water into the fresh water tank.
(6) The sprinkler system shall be provided with at least one stop valve for every 200 sprinklers that can prevent the flow of water into those sprinklers without affecting the rest of the system.
(7) Each of the stop valves provided pursuant to subsection (6) shall be protected from accidental operation.
(8) A gauge indicating the pressure in the sprinkler system shall be fitted at each stop valve and at the control station.
(9) The sprinkler heads shall be placed in positions and spaced in a pattern that will ensure an average application rate of 6 L/minute/m2 throughout each space in the accommodation areas.
(10) The pump system or pump and fresh water tank required by subsection (1) shall be situated outside the accommodation areas and as far as possible from the main machinery space.
(11) The sprinkler system shall be
(a) installed in accordance with National Fire Protection Association 13, Standard for the Installation of Sprinkler Systems; and
(b) tested and maintained in accordance with National Fire Protection Association 13A, Recommended Practice for the Inspection, Testing and Maintenance of Sprinkler Systems.
