ABSTRACT:
The present method and apparatus are directed to a fire control system for use with a drilling rig. Multiple nozzle means are positioned around a drilling rig at selected locations to spray water delivered through fire hoses onto the rig to prevent fire damage. The equipment utilizes a skid-mounted engine and connected centrifugal pump for delivery of water from a closed storage tank. An engine control unit adjusts the throttle to an operating speed which delivers no water during normal operation. Subject to control by switch means on the rig floor, either hard wired or by means of a radio transmitter and receiver arrangement, the engine control unit switches the engine to maximum power output. An alarm is also sounded when this occurs. So long as the engine is running, operating lights signal rig personnel that the equipment is operative. The equipment is switched from a slow speed operation to a maximum power output to deliver water under control of rig personnel.
