The method of laying and the construction of an oil pollution barrier for use on the ocean or other bodies of water. The method comprises the simultaneous and synchronized unreeling from a vessel of a resilient barrier strip formed with spaced inflatable pockets and a sectioned resilient hose containing a liquid chemical. Each inflatable pocket has an opening formed at the base which is in communication with an injection tube which is removably mounted below each pocket in the lower edge of the barrier strip. Each injection tube contains a chemical powder, reactive with the liquid in the hose to form a gas. At a predetermined point the injection tube is forced into the hose, the hose is compressed to force the liquid upward into contact with the chemical powder, the gas formed by the reaction inflating the pocket in the plastic barrier. In alternative forms of the invention the pocket is inflated by the use of a low boiling point volatile liquid or compressed gas stored in the hose. The barrier strip and hose are unreeled until the oil slick is surrounded, whereafter the ends of the barrier and hose are cut to form an enclosure around the oil spill.

Dispersion of pollutants having specific gravities less than that of water and floating on a body of water are controlled by encircling the pollutant body with a floating reservoir wall having an open top and open bottom. The reservoir wall comprises an elongated length of flexible water-impervious material having disposed along its upper end a plurality of inflatable flotation cells inflatable through a common duct running the length thereof and having disposed along its lower end ballast means for maintaining the lower end of the wall beneath the surface of the pollutant and body of water. The ends of the reservoir wall are joined together in sealing relationship by compressively engaging inflated cells disposed along the ends of the reservoir wall. Pollutants issuing into a body of water can be directed into the interior of the enclosed reservoir formed by the reservoir wall by a flexible or inflexible conduit secured at one end around the source of pollution with the opposite end leading to the interior of the reservoir. The reservoir wall is held in a predetermined location by means of anchors resting on the floor of the body of water and connected by lead lines to the lower end of the reservoir wall.
摘要:
A barrier for control of waterborne substances having a plurality of units interconnected to one another in end to end relationship. Each unit has articulated flotation chambers and a flexible, depending skirt with permanent ballasting along the lower edge thereof. Means are provided to selectively reef the skirt and water ballasting pockets are formed on the skirt to provide restraint against wind action on the barrier.

An on-board re-inflatable containment boom for a waterborne vessel that lies substantially flat and capable of being spooled when deflated and floats in the proper orientation when inflated, that has re-inflatable float sections which are sequentially inflated during deployment and sequentially deflated during recovery, that can be repeatedly deployed and recovered for the purposes of training and testing, and that can be deployed immediately upon occurrence of an oil spill from a waterborne vessel because of its on-board location and its rapid deployment, and a control system for proper inflation and deflation of re-inflatable containment boom during deployment and recovery.

摘要:
An oil containment system aboard a vessel which includes a pneumatic system to provide power to a winch and reel assembly containing boom whereby the pneumatic supply is capable of simultaneously powering the winch-reel assembly for boom deployment through inflatable gas fed to a pneumatic motor while also inflating the boom. The inflation of the boom is accomplished by diverting, all or any portion thereof, the inflatable gas from a pneumatic supply through a hose that runs concurrently on the outside of the boom wherein appropriate rates of inflatable gas pressure are allowed to flow through the hose to feed through a valve and hose assembly that connects the inflatable gas supply of the hose to the inflatable gas containment system of the boom. The pneumatic supply originates from a single pneumatic system powering both the winch and reel assembly as well as associated brake and feeding inflatable gas pressure to the inflation hose running concurrently with the boom. The system may be manufactured in a form such that it is compact enough to be installed in, or rapidly transported to, any area or place or vessel where there is likelihood of a discharge of floating material, such as hydrocarbons, floating on a liquid surface. The present invention may also be operated through the use of pneumatic control without the benefit of electric power making it particularly useful for applications in remote areas or during a disaster when electrical power is not readily available.

The system would be utilized to confine a discharge of a floating material such as hydrocarbons floating on the surface from a vessel or structure.
