Abstract: A high temperature resistant oil containment boom having a protective cover, the cover comprising, in laminar combination, an outer layer of high temperature resistant metallic fabric, a first underlayer of high temperature resistant insulation, a second underlayer of a polymer-coated fabric, a third underlayer of high temperature resistant insulation and a bottom layer of a high temperature resistant polymer-coated material, the protective cover being unified by having at least the top and bottom layers secured together along their peripheral edges.

Abstract: A float boom for retaining a floatable material, such as hydrocarbons, floating upon a liquid surface. This float boom consists of separate and sequentially arranged buoyancy chambers having depending channels that are interconnected via a passageway such that an inflating medium is sequentially supplied to the buoyancy chambers. An automatic sealing system blocks access to each buoyancy chamber by closing the depending channel whenever the internal pressure within the channel is less than the external pressure upon the channel.

Abstract: A boom for collecting material floating on the surface of a body of water comprising: a first collapsible tube which can be stored either as flat layers of folded material or by rolling it on a roller; transverse seals along the length of the first tube to create a longitudinal sequence of first compartments; and, a second tube within the first tube, the second tube having transverse seals to form a longitudinal sequence of second compartments, these second compartments being generally concentric with the first tube and the first compartments. Pressurized gas communicates with each of these separate compartments so as to provide pressurization thereof.

Abstract: A boom for collecting material floating on the surface of a body of water which, by its configuration, requires considerably less inflation air to achieve the required degree of buoyancy to float the boom than is normally required. One embodiment incorporates an elongated collapsible first tube compartmentalized into a series of sequential compartments. Within such compartments are located inflatable flotation tubing which expands the walls of these compartments thus displacing water, thereby increasing the buoyancy of the boom. Such inflatable floatation tubing may be configured as a longitudinal sequence of inflatable annular rings within these compartments; or, the inflatable floatation tubing may be configured as a spiral coil disposed along the length of the compartments biasing the walls of the compartments outwardly. The inflation tubing can be connected by a conduit to a tube secured to and extending the length of the first tube for providing inflation gas thereto.

Abstract: A boom for collecting material floating on the surface of a body of water comprises a first collapsible tube which can be stored either as flat layers of folded material or by rolling it on a roller. Transverse seals are provided along the length of the tube to provide a longitudinal sequence of compartments. A reactant body is disposed in at least one compartment, and being capable of producing an inflating gas. The reactant body is disposed within a pouch which is frangible under pressures applied by rollers or the like during the deployment of the boom from its stored condition. In a modification, a small collapsable tube is provided in longitudinally secured relationship to the first tube and the interior of the small tube is provided with fluid connection to each of the successive compartments.
