2. Description of Related Art including Information Disclosed under 37 CFR 1.97 and 1.98
The Oil Pollution Act of 1990 (33 U.S.C. 2701-2761) amended the Clean Water Act and addressed the wide range of problems associated with preventing, responding to, and paying for oil pollution incidents in navigable waters of the United States. It created a comprehensive prevention, response, liability, and compensation regime to deal with vessel- and facility-caused oil pollution to U.S. navigable waters. OPA greatly increased federal oversight of maritime oil transportation, while providing greater environmental safeguards by:
Prior oil containment booms generally require hours of labor to install and uninstall due to an elaborate attaching system of cables and bolts. Routine installation or removal of oil containment booms for maintenance, replacement, and cleaning may become very expensive due to the man hours of labor required in uninstalling and reinstalling the oil boom in addition to the time for maintenance and cleaning. Many times it is necessary to uninstall and reinstall oil containment booms as quickly as possible. One example is when a large oil containment boom needs to be drawn in to confine a smaller area as when a spill from refueling or other type spill occurs within the larger boom and the boom should be made smaller to act as a net confining the oil to a smaller spill area. Prior art booms do not lend themselves to such speedy conversions.
U.S. Pat. No. 4,016,726, issued Apr. 12, 1977 to Campbell, indicates a connector hinge for attaching oil spill containment booms having a male cylindrical connector which fits loosely within a female cylindrical connector to allow easy movement of both connectors in both a vertical and horizontal direction. A resilient gasket is disposed within the male cylindrical connector such that the gasket forms an oil-tight seal between the male connector and female connector. The female connector is tapered along its length to allow easy disposition of the male member within its cylindrical cavity. Both the male and female connectors can be attached to a floating oil spill containment boom, a substantially immovable object such as a pier or jetty, or a floating tow assembly. The loose fit between the male and female connectors allows the connector hinge to adjust to tidal variations as well as additionally aiding in placement of the male connector within the female connector. The gasket material is formed of foam rubber, rubber, or any other suitable resilient material capable of forming an oil-tight seal. The gasket is formed in either a rectangular shape or beaded to aid in securing the gasket to the male connector.
U.S. Pat. No. 5,971,660, issued Oct. 26, 1999 to Duchesneau, puts forth an extensible barrier to retain a hydrocarbon slick between a fixed and a floating structure to confine potential oil spills while transfer in, between a ship and a wharf, or between two ships. It is made of a barrier that is fitted on a IS beam fixed on the wharf on which the barrier can be moved vertically with a float, according to the waterline. This barrier is mobile and detachable, of a mechanical. pneumatic or hydraulic type, and can be easily operated by one man. A waterproof canvas is placed on the mechanical barrier to confine the oil slick; a spring thrusts a shoe against the hull of the ship and is kept in place by magnets. A mechanical arm slides against the hull, with the help of balls. A hydraulic alternative stops oil diffusion by creating a current. A pneumatic alternative uses a curtain of bubbles that burst at the surface and hold the oil while creating a current.
U.S. Pat. No. 3,973,406, issued Aug. 10, 1976 to Casey, is for a collapsible, quickly deployable floating containment boom which comprises an elongated curtain-like partition of strong, flexible, impervious material supported in a substantially vertical position in the water by a plurality of outrigger-type flotation units spaced along the partition. The partition is in the form of an elongated, flexible belt which has a smooth surface on the side opposite the flotation units, and the smooth side surface engages the material to be contained by the barrier. The barrier has sufficient longitudinal flexibility to encircle an oil spill or a ship that might be unloading or loading oil, and the outrigger flotation units support the partition or belt at a height above the surface of the water which is approximately ⅓ to ½ of the partition width. Each outrigger flotation unit comprises a frame and a float. The frame is connected to the side of the partition or belt for pivoting action about a vertical axis extending parallel and immediately adjacent to the side of the belt, and the float is connected to the frame for pivoting action about a horizontally extending axis. This articulation of the frame and float provides a self-stabilizing action of the outrigger flotation units. It also permits each float and frame to be folded back flat against the side of the belt to facilitate deployment of the floating barrier through narrow passageways such as between ships and piers. This articulation also permits the barrier to be folded in accordion fashion for compact storage and transport. The device can be used to connect an end of the floating barrier to a pier or other fixed object and yet permits the barrier to move up and down with the changes in the tide level.
U.S. Patent Application #20070201953, published Aug. 30, 2007 by LeBlanc, is for a containment boom guide system for guiding and containing a floating containment boom to a fixed structure such as a pier, ship, column, dock, sea wall, or other like structure. The guide system is made up of one or more boom guide(s) and allows lateral and vertical movement of the floating containment boom while keeping the boom secure to the fixed structure.
U.S. Pat. No. 5,538,359, issued Jul. 23, 1996 to Wadle, provides a quick release boom connector for a remotely disconnectable floating containment boom, which includes male and female portions of a connector and a release element which holds the male and female portions together when they are operatively engaged. The containment boom includes a remote activating element attached to the release element. The remote activating element can disengage the release element from the male and female portions of the boom sections from a remote location, thereby permitting the boom sections to disconnect and separate.
U.S. Pat. No. 5,190,402, issued Mar. 2, 1993 to Vick, shows a fire resistant boom connector for connecting adjacent oil containment booms. The boom connector includes cooperating connector portions, each of which includes a base portion, an elbow portion, and an engaging portion. A slot bounded by the base portion, the elbow portion, and the engaging portion is adapted for receipt of a cooperative engaging portion to interengage the connector portions.
U.S. Pat. No. 4,003,206, issued Jan. 18, 1977 to Tanksley, claims a universal end connector for releasably coupling together aligned ends of a floating boom or the like. The end connector is formed with a normally vertically extending body having a first side adapted for mounting to the end of the boom and a second coupling side formed as a yoke-like bifurcated side having a pair of spaced apart neck portions terminating in enlarged head portions. The neck and head portions define a throat and enlarged cavity therebetween dimensioned for receipt of the head and neck of a similarly formed second end connector. The throat and cavity of the end connectors are open at least one of a top and a bottom end thereof to permit selective positioning of the end connectors in coupled and uncoupled relation. The enlarged head of the end connector is preferably formed with inwardly facing and inclined surfaces on either side of the head so as to cause the head portions to be pulled together and narrow the throat to enhance coupling under normal loading of the connector.
U.S. Pat. No. 3,766,738, issued Oct. 23, 1973 to Gauch, discloses an apparatus for supporting a floating boom which forms a barrier on the surface of a liquid and for forming a seal between the end of the boom and a fixed structure, for example a dock. The apparatus allows lateral and vertical displacement of the boom with changes of wind, current, or tide while maintaining the seal. A deformable, resilient wall held in pressure contact with the dock while supported on a vertically and laterally movable frame displaceable along a vertical pipe spaced from the dock maintains the seal to prevent oil or other pollutants on the surface of the liquid from passing between the end of the boom and the dock.
U.S. Pat. No. 4,348,136, issued Sep. 7, 1982 to Donovan, illustrates a spill containment device adapted for attaching a containment boom to any ferromagnetic surface at the water line, the device including a base member in the form of an elongated arm having a medial portion and opposite end portions, a float at the medial portion of the arm for imparting buoyancy to the device relative to a body of water, a magnet carried by a first of the opposite end portions for magnetically attaching the device to a ferromagnetic surface, a second of the opposite end portions including a loop for connecting a line thereto for applying a force to the device to detach or disconnect the magnetic connection thereof with an associated ferrometallic surface, and first and second couplers for respectively fixedly and movably connecting a containment boom to the device.
U.S. Pat. No. 3,984,987, issued Oct. 12, 1976 to Light, Jr., provides an apparatus for a marine facility which prevents silt from entering the facility and also provides spill containment. A floating barrier provides the containment and a flexible curtain attached to the barrier and having devices anchoring the curtain to the floor of the water prevents silt from entering the facility. The barrier rises and falls with the tides and openings in the curtain permits the tidal flow to enter and leave the facility. The apparatus is attached to fixed structure in a suitable manner. The barrier and curtain can be moved to permit passage of a ship.
