Alameda, California to protect itself with an innovative floating defensive barrier

Summit, New Jersey-based Wave Dispersion Technologies (WDT), a private maritime technology company, has completed installation of the WhisprWave Small Craft Intrusion Barrier (SCIB) at USCG ISC Alameda, California. The floating marine barrier encloses a security zone of 2,400 feet and incorporates two swinging gates of 725 feet and 825 feet to allow for movement of U.S. Coast Guard Cutters into and out of the exclusion zone. The total contract, in excess of $900,000, represents the largest completed contract to date for Wave Dispersion Technologies. Alameda is a city on a small island next to Oakland, California in the San Francisco Bay. The WhisprWave SCIB received installation permission from various federal and state environmental authorities. California’s environmental requirements are the most stringent in the nation.

The SCIB’s swinging gates pivot from WhisprWave’s proprietary Pivot Buoys, which are restricted to a specified watch circle so as to maintain a limited SCIB catenary. Their design prevents the barrier from impinging on the Federal channel or into the exclusion zone. The pivoting barrier security gates are the largest of their kind in the world.
