Abstract

Embodiments of this invention describe a float for use with a running gear entanglement system ('RGES') deployed on water, in addition to an improved system and method for using an RGES deployed in water. The floats lock securely onto the RGES mainline rope. The floats may be stacked for additional buoyancy or to allow for multiple RGES ropes in the same deployment. The floats are designed to permit the RGES to be retrieved/stored on and deployed from a reel. The floats may be constructed of any color and may also be luminescent. The floats may be ballasted to assist in anchoring the RGES.

Description

FLOAT FOR USE IN WATER-BASED SECURITY SYSTEM
CROSS REFERENCES TO RELATED APPLICATIONS.
This application claims the benefit of United States Provisional Application Ser. No.60/831 ,119, filed 14 July 2007, the contents of which are hereby incorporated by reference herein in their entirety.
FIELD OF THE INVENTION.
Embodiments of this invention include using floats with a security system/barrier deployed on water, and more particularly, for use with a security barrier of the type known as "running gear entanglement system" and describe an improved apparatus and method for this purpose.
COUNTERING TERRORISM.
This invention may be utilized in countering terrorism. Unwelcome objects, such as boats, attempting to intrude into populated, secure, or sensitive areas are commonly employed in terrorist activities. As part of efforts to counter terrorism, there is an urgent need to prevent penetration of such objects into such populated, secure, or sensitive area. One or more embodiments of this invention will aid in this prevention.
BACKGROUND OF THE INVENTION.
This invention concerns using floats with a security system/barrier deployed on water of the type known as "running gear entanglement system" ("RGES").
In recent years, security agencies, such as the United States Coast Guard, have been looking forways to deter water-borne terrorist attacks. To this end, one newly developed law enforcement tool are nets designed to tangle the running gear of boats entering restricted waters.
The nets are commonly known as a "running gear entanglement system" or "RGES". The RGES is typically a line that floats on the surface of the water, with 40-inch long loops spaced every 8 inches. Inflatable 15-inch buoys are placed approximately every 100 feet. Lights may also be attached approximately every 100 feet, midway between the flotation buoys. Anchoring systems may be required every 200 feet.
The RGES would be used primarily to temporarily cordon off a section of harbor or bay. The RGES would function analogously to the yellow tape police use on land.
An RGES may be used to help protect large gatherings such as a political convention, conference, or sporting event. The RGES would be used to provide a barrier around a high value asset or to establish a "line of demarcation", thereby outlining a security or safety zone and allow security forces sufficient time to react and counter a threat.
The RGES could operate in typical harbor, anchorage, and wharf environments including fresh, salt, and brackish waters, in air and water temperatures and thermoclines, as would typically be expected in a port/harbor environment.
Thus, one concern of the use of an RGES is its environmental impact. Depending on where the nets are used, turtles, manatees, sea lions and other aquatic life might become snarled. Although tests to date have concluded that the nets won't harm wildlife, concern does continue.
Therefore, it is desired to maximize the efficiency of an RGES with minimal effect, if any, on the surrounding environment.
BRIEF SUMMARY OF THE INVENTION.
In one embodiment, this invention comprises a float for use with an RGES.
In another embodiment, this invention comprises a method for using a plurality of floats with an RGES.
In still another embodiment, this invention comprises apparatus using a plurality of floats with an RGES.
BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWING.
Fig. 1 is a view of one embodiment of this invention. Fig. 2 is another view of one embodiment of this invention.
Fig. 3 is another view of one embodiment of this invention.
DETAILED DESCRIPTION OF THE INVENTION.
In a preferred embodiment of this invention, a float is described for use with an RGES.
The float is preferrably made of polyethylene, although any, lightweight, moldable, buoyant material may be used. The float has a modular design to allow stacking and securing multiple floats on top of each other.
The float has a locking mechanism to allow attachment to the RGES rope. This locking mechanism is comprised of raised ridges in the underside of the float. These ridges act in conjunction with a groove on the dorsal area of the float, allowing a uniform compression of any given diameter rope. This system has the effect of locking the float in position on the rope.
The float contains apertures to reduce or eliminate heave forces on the RGES system when deployed. The apertures also are used for hand holds to assist in retrieval of the system from the water.
Individual floats may be stacked one upon the other as desired. The floats are held one upon each other by attachment means well known in the art, including, without limitation, bolts, nuts, and/or washers. Preferably, attachment occurs at the four corners of the float. The fasteners also create an opportunity to mount warning devices and sensors above and below the water.
In use, a plurality of floats are locked onto a RGES mainline rope via the locking mechanism. Preferrably, pairs of two stacked floats are placed approximate six feet apart along the RGES mainline rope, but the stacking and placement combinations may be adjusted for any particular application.
The floats provide a method of delineation for ropes floating in the water. Also, the floats provide additional buoyancy for the RGES. This additional buoyancy increases the propeller-catching capabilities of the RGES.
Another embodiment of this invention comprises utilizing a plurality of floats to increase the number of RGES systems deployed in a given usage. This outcome may be accomplished by stacking floats on top of each other and locking individual RGES lines to different, corresponding floats in each stack. For example, with a series of four-stacked floats, one could locking one RGES line in the second lowest float of each stack and another RGES line in the uppermost float of each stack. The resulting RGES system would have increased propeller-catching capabilities.
Furthermore, the float may have a shape and design specifically chosen to allow an RGES system including locked-on floats to be stored or rolled onto a reel. This reel-friendly characteristic permits for easy deployment and retrieval of an RGES system.
In addition, the float may incorporate additional safety features, including, without limitation, being of any desired color and/or luminescent to glow in the dark.
Another embodiment of this invention comprises a series of floats deployed along an RGES system in a drogue configuration slowing the motion. These configurations, well known in the art, would have the beneficial effect of slowing down a vessel which comes into contact with the RGES system.
Still another embodiment of this invention comprises ballasting a series of floats. Such ballasting, utilizing methods well known in the art, would allow the floats to assist or act as an anchor for the RGES system, other netting, or other lines in the water column.
Therefore, although this invention has been described with a certain degree of particularity, it is to be understood that the present disclosure has been made only by way of illustration, and that numerous changes in the details of the apparatus and method may be resorted to without departing from the spirit and scope of the invention.
