Abstract

A method of fire-fighting burning oil wells comprises dispensing liquid nitrogen to the burning site to prevent or inhibit oxygen from fuelling the flames. For applying the method there is used a remotely operated vehicle provided with a source (7) of liquid nitrogen and an articulated deployment boom (11) capable of supplying the liquid nitrogen to the site (15) of a burning oil well.

Description

TITLE
METHOD AND VEHICLE FOR SUPPRESSING OIL WELL FIRES USING LIQUID NITROGEN
The present invention provides a method of successfully fighting burning oil wells employing liquid nitrogen and to the use of a remotely operated vehicle for carrying out the method.
According to one aspect of the invention there is provided a method of fire fighting burning oil wells, by dispensing liquid nitrogen to the burning site to prevent or inhibit oxygen from fuelling the flames. Preferably the liquid nitrogen is dispersed around the well head in a plurality of spaced apart jets. Preferably the fire- fighting operation is controlled by use of a remotely operated vehicle.
According to another aspect of the invention there is provided a remotely operated vehicle provided with a source of liquid nitrogen and an articulated deployment boom capable of supplying the liquid nitrogen to the site of a burning oil well. Preferably the liquid nitrogen supply means comprises a supply line linked with a ring of discharge ports for the liquid nitrogen adapted to surround the well head under treatment. A discharge line may be provided to return unused nitrogen from the well head. Preferably the vehicle includes an electrohydraulic power pack mounted on the vehicle and provided with a water jacket to enable continual cooling of the motor to take place. Advantageously the vehicle is a vehicle driven by an endless track. The vehicle may include one or more of the following: a remote control console situated at the control centre; a multi¬ directional hydraulic powered water cannon with a viewing camera; a multi-directional powered water cannon with diffuser branch nozzle and viewing camera; an anti¬ personnel mine detonation spoiler; a high resolution colour camera in a continuous flush water jacket mounted at the end of the articulated boom and a torque tool mounted at the end of the boom.
By way of example, a preferred form of vehicle for fighting oil well fires will now be described with reference to the accompanying diagrammatic drawing which is a perspective view and shows schematically the manner of extinguishing an oil well fire.
A remote control console is shown at 1, this being situated in the control centre at a safe distance from the well head 15. A permeable fire hose surrounding electro/hydraulic umbilical is shown at 2, and 3 shows an intrinsically safe hydraulic power pack in a continuous flush water jacket. Mounted on a tracked vehicle 13
SUBSTITUTESHEET with endless track 14 are a multi-directional hydraulic powered water cannon 4 with viewing camera and a multi¬ directional hydraulic powered water cannon 6 with diffuser branch nozzle and viewing camera. An anti¬ personnel mine detonation spoiler is shown at 5. A liquid nitrogen supply line is shown at 7, the liquid nitrogen being fed to a nitrogen discharge ring 8 with an array of discharge ports 9 for distributing the nitrogen; a discharge line 10 is provided for supplying additional liquid nitrogen or other fire-fighting medium to the well head 15 if such is required. A deployment boom 11 is mounted on the vehicle 13, and mounted on the boom is a high resolution colour camera 12 in a continuous flush water jacket. Oil well valves are shown at 16, 17 and 18, and 19 shows the flames of the burning oil well. 20 denotes a torque tool at the end of the boom 10.
Commercial applications for the vehicle illustrated and described above are as follows: i) Accessing well heads through areas that are mined and/or on fire which pose a risk to human intervention. ii) Observation at well heads by use of remote cameras from close quarters without risk to human life, iii) Remote removal of well head debris.
SUBSTITUTE SHEET iv) Ability to actuate any remaining valves on well head while fire is still burning. v) Carry water cannon to fire location. vi) Carry any fire fighting apparatus or systems
(e.g. halon, dry ice, etc.) to the direct fire location. vii) Ability to place around the well head a liquid nitrogen dispenser to feed liquid nitrogen to cool the well head and starve the fire of oxygen so that re-ignition does not occur. viii) Ability to land on well head replacement valve assemblies in controlled manner and carry out well killing operations. ix) Ability to conduct work safely in atmospheres contaminated with toxic and/or sour gas and/or explosive mixtures.
SUBSTITUTESHEET
