| 141 | Fire extinguisher | US47628674 | 1974-06-04 | US3887011A | 1975-06-03 | DOKES SAMUEL; ISAIAH ALVIN K |
| A fire extinguisher for oil wells, and the like, has a first pipe connected to a well pipe and a second pipe branched from the first pipe. First and second valves are arranged in the first pipe, while a third valve is arranged in the second pipe. These valves are connected together and restrained from movement so that the first and second valves are normally-open and the third valve is normally-closed. When an element constructed from lead, and the like, is melted due to an increase in temperature caused by a, for example, fire in the first pipe, the first and second valves are released and permitted to move to closed positions, and the third valve is permitted to open, thus smothering the fire contained in the first pipe between the first and second valves while bypassing the communication with the oil well through the second pipe and into the atmosphere.

| A method and means for protecting the structural integrity of offshore oil and gas producing rigs from damage due to blowout fires. The invention includes vertical, tubular members which form passageways for water and are in fluid communication with cross members providing lateral support. The water may be pumped either through an inlet depending into the water and positioned between the surrounding tubular members and then forced throughout the tubular members by a pump that is supported on a lower platform above or below the lower surface of the water, alternatively an independent vessel may be connected to one or more of the tubular members by means of a subsea line to circulate water from the sea through each of the tubular and cross members. Nozzles may be positioned on the tubular members pointing inwardly and downwardly toward the wellhead to provide a spray that may be directed into a flame and also used to direct a cooling stream to anyone of the platforms.

| 143 | Thermal sensing actuating device | US3744506D | 1972-02-22 | US3744506A | 1973-07-10 | MILSTED J |
| The present disclosure is directed to a fail safe device to close an oil or gas well that has ignited during drilling or workover operations working in conjunction with pressure accumulators and blow out preventers. The apparatus is installed in a line the upstream side of which is pressurized by the accumulators and the downstream side of which is connected to actuate the blow out preventer. The device has a pair of normally closed check valves which are spaced apart but which may be moved together to mate and unseat the valves and permit the pressurized fluid from the accumulators to actuate the blow out preventer. The movement of the check valves is caused by a fluid motor which while being under pressure is restrained from unseating the valves by a barrier of a material which is normally solid, but when attaining high temperature due to the fire will flow to permit the fluid motor to cause the normally closed check valves to mate and unseat and thereby apply the accumulator pressure to actuate the blow out preventer to close the well.

| 144 | Apparatus for preventing pollution from offshore oil wells | US3664429D | 1971-06-07 | US3664429A | 1972-05-23 | JONES EUGENE G |
| An apparatus for catching oil from high pressure offshore oil wells so as to prevent pollution of the adjacent water. A substantially enclosed container is provided with an entrance throat area at one end of the container, and an exit at an opposite end thereof. The incoming oil from the oil wells is deflected rearwardly by a formed front wall means whereby the oil is deflected rearwardly of an upturned marginal edge of a bottom wall for the substantially enclosed container and is removed therefrom, preferably by gravity. The bottom wall ensures that no oil spills into and pollutes the adjacent water.

| An extinguishing manifold around the opening of an oil well and a control circuit actuated by heat, air pressure or manually to open a valve to cause carbon dioxide to be dispensed from the manifold to prevent or extinguish an oil well fire. The carbon dioxide may also be injected into the well casing, and used to cool the exhaust pipes of engines at the well site. On an offshore rig, the carbon dioxide container is attached to a leg of the platform, below water.

| 146 | Oil or gas pollution control apparatus and method | US3602299D | 1970-05-12 | US3602299A | 1971-08-31 | MOZIC JOSEPH D |
| A method which is particularly suitable to prevent oil pollution of water in the vicinity of an offshore drilling operation. Apparatus is provided for use on a ruptured oil and/or natural gas pipe where fluid is issuing under pressure from the pipe. A heat dissipating screen is disposed in the path of the fluid and raised to a predetermined position. The fluid is then intentionally ignited (thus preventing pollution), the heat dissipating effect of the screen confining the flame to a region above the screen, spaced from the open end of the well pipe. A thermal radiation shield can be provided as well as water coolant members for the screen and shield.
