History of the WhisprWave® Module.FLOATING BREAKWATERSWave Dispersion Technologies, Inc.(WDT) developed the WhisprWave®floating articulated breakwater technology Marine Physicalto afford protection to ports, harbors, Barriers, Floatingmarinas, beaches, and private propertysubject to destructive or annoying wave / Breakwaters andwake forces. There are three primaryconfigurations of the WhisprWave® Warning Buoysfloating breakwater: Ocean FloatingBreakwaters, 2-Layer FloatingBreakwaters, and 3 Layer FloatingBreakwaters.PHYSICAL BARRIERSThe modularity and the flexibility of theWhisprWave® erosion controltechnologies led to discussions with theUnited States Navy and United StatesCoast Guard about developing variousmaritime port security barriers and Wave Dispersion Technologies, Inc.related products for their Homeland 269 Sheffield St. Mountainside, NJ 07092-2318Defense and Military Force Maritime Phone (908) 233-7503Protection needs.
