Abstract: An oil spill reclamation system utilizes an elastomeric foam functionalized to exhibit both oleophilic and hydrophobic properties. The foam material is contained in permeable pods connected to each other in a chain to form a boom strung in a closed loop around the oil spill. As each pod is brought into contact with the spilled oil, the foam material absorbs it to saturation. The pods are linked through an inflated flexible hose that ensures their buoyancy. The chain of pods is continuously processed in one or more barges that include equipment to press the absorbed oil out of each pod and a conveyor system for retrieving the pods from the water, pulling them through the press, and returning them to the water in a continuous cycle of operation. Positioning buoys with vertical rollers are used to retain the general shape of the containment loop defined by the continuous boom.

Abstract: The present invention pertains to a floating breakwater structure in the pe of a "V". This breakwater design allows for a wide range of wave periods, unlike previous floating breakwaters. The construction of the instant invention is that of a suspended curtain which deflects and redirects the waves that are incident thereto rather than absorb or reflect incoming wave energy. This design results in a substantially smaller structure with reduced mooring loads. Moreover, the floating breakwater of the instant invention allows for fast deployment that can be either shipped in sections and assembled on site or assembled in sheltered waters and towed to a site for deployment. The breakwater of the instant invention is intended for temporary coastal operations such as military force projection and sustainment, dredging, coastal civil construction and repair, oil spill recovery, and search/rescue relief missions.

Abstract: In order to control oil accidents and to prevent the oil film drifting on the water from spreading, an oil adsorber 1 is provided, in particular shaped as a barrier 2. This barrier 2 is designed in two parts. Both cells 9, 10 are completely filled with glass fiber material or with corresponding fiber mats 11, 12. The glass fibers 28, 30 of the top cell 9 are waterproofed, by an appropriate coating, whereas the fibers of the bottom cell 10 are not treated, so that they absorb water 6. In both cases epoxy resin or a synthetic resin having the same or similar properties are used, so that a long service life is achieved with optimum solidity and design possibilities. The oil adsorbers 1 thus obtained may be used both as barriers 2 and as flat suction elements, for example to clear bilge waters from ships 3. It is also conceivable to use the flat or funnel-shaped elements for collecting components of an aqueous solution, for example.

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 deployable spill containment boom which, when not in use, is stored along a shoreline. Attached to one end of the deployable boom is a floatation device. The boom is deployed into a moving waterway by means of a cable to which the boom is attached. The deployment cable runs through a pulley attached to an anchor permanently located on the bottom of the river. The other end of the deployment cable is attached to a winch system located on shore on a "take-up" reel. During an oil spill, the system is actuated by a radio signal. The take up reel reels in one end of the deployment cable and a "supply reel" pays out the cable through the anchored pully cable. The deployable boom is then pulled away from the shoreline. Since the boom floats it remains on the surface of the water while the cable is deployed The deployment cable winding operation causes the boom to be extended out into the river. The end of the boom with the floatation device extends into the river to the location above the anchor.

The angular relationship may be 180.degree. and the shaping of the boom made possible by the limited flexibility of the battens of the desired boom shape may be effected by having alternate joints held in an obtuse angular relationship.
