Benefits of technology

[0008]The present invention overcomes some of the difficulties of the past, including those mentioned above in that it comprises a relatively simple in design and highly effective port security barrier which prevents bomb laden waterborne craft operating at speeds around 50 knots from entering a port for the purpose of disabling and seriously damaging military ships.
[0011]Port security barrier modules for the port security system may be used as gates to allow small craft to pass through the system. By positioning the pontoons perpendicular to the main support beam drag is reduced when the gate is opened and closed.

Problems solved by technology

However, these port security barriers are not capable of halting a deliberate attempt to penetrate the barrier
However this type of barrier is not effective as a deterrent to larger bomb laden watercraft operating at speeds of 50 kts or more.

Embodiment Construction

[0020]Referring to FIGS. 1, 1A and 5, the port security barrier 10 comprises a floating segmented boat barrier, modular, floating barrier that is installed in lengths ranging from a few hundred feed (example, two hundred feet) to over a mile. Barrier 10 operates to a stop a hostile high speed waterborne craft 12 which is attempting to inflict heavy damages on a port facility and the military ships anchored at the facility. Arrow 13 indicates the direction waterborne craft 12 is traveling throughout the figures of the drawings.

[0021]The port security barrier 10 is assembled using the port security barrier modules 14 illustrated in FIG. 1, each of which is approximately 50 feed in length. The width of each port security module 14 is about 18 feet, the height is about 9.4 feet and the weight is approximately 8,000 to 8,500 pounds.

[0022]A mooring system 15 is also provided for the port security barrier 10. The mooring system 15 includes mooring buoys 16 which are positioned approximat...

Abstract

A port security system comprising a continuous modular, floating barrier that is installed in lengths ranging from a few hundred feet to over a mile. The port security system is designed to stop high speed explosive laden waterborne craft traveling at speeds of fifty knots or greater from penetrating a military or commercial port. Each module of the port security system includes a capture net and net support structure which operates to stop the waterborne craft and prevent entry into the port.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates generally to a port security barrier system which provides protection for military and commercial ports and ships docked at these ports. More particularly, the present invention relates to a floating barrier which utilizes nylon netting to prevent a small watercraft carrying explosives or the like from damaging a military or commercial port or ships docked at these ports.[0003]2. Description of the Prior Art[0004]There is currently a need to protect military ships from attack by explosive laden watercraft traveling at high rates of speed. Such explosive laden watercraft may include commercial power boats, small military craft and pleasure craft. These boats are generally less than forty feet in length, have a weight of around 10,000 pounds and travel at speeds of up to 52 knots. The small watercraft threat may be defined as watercraft which have a kinetic energy threshold of approximately 1...
