The instant application discloses, among other things, a foam-based boom to provide for a spill containment on either water or land. In one embodiment, an expanding foam, such as polyurethane, may be used form a cylindrical or other shaped boom, providing strength, flexible boom shape and size, and easy deployment. Multiple types of foams may be used together; for example, a water absorbing foam may be used in conjunction with a waterproof foam, to allow for a boom to extend both underwater and above water.

An offshore atoll system includes a continuous barrier, the continuous barrier having one or more modular sections coupled together, wherein each of the one or more modular sections have at least one concave surface positioned at a sea surface. The continuous barrier also includes one or more thrusters disposed along a length thereof. The continuous barrier is provided to reduce a magnitude of incoming waves on at least one side of the continuous barrier.

In order to provide a containment boom capable of functioning as a barrier for certainly preventing the containment of oil spill in no concern to momentary violent movements of waves and currents, the containment boom comprises a plurality of float units and a coupling portion by which adjacent float units are coupled to one another. Each of the float units comprises a housing having an oil shielding surface perpendicular to sea level, a float portion having a buoyant force, and a plummet portion positioned under the float portion. In addition, the float portion and the plummet portion are adjusted so as to locate a water line to approximate middle position of vertical length of the oil shielding surface. Furthermore, the coupling portion is a flexible coupling portion for varying a relative position between the adjacent float units.

A float boom for confining material floatable on a liquid surface during high temperature conditions, comprising: an elongated floatable tube formed of fluid impervious material; a source of fluid under pressure for cooling the boom during high temperature conditions; piping connected to the source of cooling fluid for distributing the cooling fluid over the length of the boom; and, a protective cover, of a fluid-absorbing material, mounted over the tube, the cover having peripheral edges adapted to engage the boom to encase the tube therein, the piping distributing the cooling fluid over the tube and under the cover to soak the cover over its length.

A floating barrier wall includes a number of individual barrier units each comprising a housing formed in the general shape of a highway barrier having a top wall, a bottom wall, opposed end walls, and, opposed side walls interconnected to form a hollow interior which is preferably partially or completely filled with a foam material. A ballast weight is secured to each barrier unit, either along or beneath the bottom wall, to maintain them in an upright position in the water. Cables, couplers and/or other connectors are employed to mount adjacent barrier units end-to-end to form a barrier wall which can encircle a vessel or otherwise isolate an area within a seaport to provide security.

A rapidly deployable breakwater is disclosed having a primary barrier containing liquid under pressure, and one or more overtopping barriers. The primary barrier floats at, and extends substantially below, the surface of the water, while the overtopping barriers are positioned on the primary barrier and extend substantially above the surface of the water, the combination being adapted to attenuate wave action in open water. The liquid in the primary barrier is pressurized to a level substantially greater than the pressure of the surrounding water, and such pressure may be maintained or varied during the period of deployment of the breakwater.

An improved heat-resistant surface contaminant containment boom is described, which has a floatation section incorporating refractory materials and spacing materials providing an air-gap around an inner float assembly which can be formed of less heat-resistant and more flexible materials. Further, the boom provides a water wicking action which draws water into the boom to be converted to steam. Provision is made for the steam to escape from the boom removing heat therefrom allowing the float assembly within to remain at a cooler temperature.

A system and method for containing oil or other contaminants which have leaked from an oil tanker or similar structure is disclosed. A series of flotation members are connected end to end and stored around the perimeter of the tanker. A membrane is folded and packed into a recess in each member and held between the member and the tanker. The members are held against the sides of the tanker by a movable stay. In case of an oil leak, a triggering mechanism sequentially moves the stays to release the flotation members, which drop off the tanker into the water. One edge of the membrane is attached to the members while the opposite edge of the membrane is free. The free edge of the membrane falls from the members so that the membrane forms a curtain in the water. Each flotation member is further connected to adjacent members by a flexible jacket and adjacent edges of each membrane are connected to each other. In this manner, a continuous curtain surrounds the tanker to prevent passage of all or most of the spilled oil. The curtain and/or the tanker may be maneuvered to best contain the spill. The curtain may be detached from the tanker and maneuvered to pinch off and isolate the spill from the tanker.

A flexible, fence-type, water-borne pollutant containment boom is disclosed having a flexible, permanently attached tension reinforcing belt of continuous, substantially parallel, high modulus, aramid fibers adhesively secured to the boom proximate its bottom edge and having a plurality of handles spaced along the top edge of the boom, the handles being molded on both sides of the boom and overlapping the top edge and surrounding openings cut in the boom proximate the top edge leaving flaps of boom material to selectively close the openings.

A barrier for water carried pollutants comprises a series of end to end connectable boom sections containing a flotable material; fluid impervious connectors for the ends of the boom sections; flexible draft members and associated connectors for maintaining the integrity of the boom if it becomes necessary to replace one or more of the boom sections, wherein the flotable material comprises a plurality of closed-cell foam, hollow, cylindrical blocks and end closure members for each end of each block.
