§ 36 Firewater supply
All facilities with accommodation shall have a sufficient supply of firewater to combat fires and suppress gas explosions if this can result in lower explosion pressure, cf. Section 37.
Manned facilities shall have firewater supply from fire pumps or other independent supply to ensure sufficient capacity at all times, regardless of whether parts of the supply are out of service.
Simpler facilities with emergency quarters shall have a firewater supply from a fire pump or other equivalently reliable supply.
Simpler facilities without emergency quarters shall have an adequate supply of firewater or passive shielding so that the personnel by evacuation can be protected from fires that can occur.
The firewater system shall be designed such that a pressure stroke does not make the system or parts of it inoperative.
On facilities where firewater is supplied from fire pumps, the pumps shall start up automatically in the event of a pressure drop in the fire main and fire and gas detection. Fire pumps shall also be capable of being manually activated from the central control room and at the propulsion unit. Propulsion units for fire pumps shall be equipped with two independent starting arrangements. Automatic disconnection functions shall be as few as possible.
Firewater piping shall be designed and placed such that a sufficient supply of firewater is ensured to any area on the facility.
