PROTOTYPE PERFORMANCE CHARACTERISTICS OF TWO FLOATING BREAKWATERS

The performance characteristics of floating breakwaters, i.e., the transmission coefficients, anchor forces, and accelerations in heave, roll, and sway, are evaluated from field measurements on a concrete modular type installed at two different locations in Alaska, and a pontoon-type installed at a location in the State of Washington. In all three instances, the installations served to protect small boat harbors from local, wind generated waves. The measurements were planned with the combined purpose of evaluating the breakwater types under different wave exposures and to supply basic data for the verification and development of a theoretical predictive model for breakwater performance. The instrumentation system was designed with multiple-channel, digital recording capability and packaged for use in remote locations, requiring only periodic maintenance checks and tape changes. The system can be set to be activated by any selected wind speed and sample the various input sensors at prescribed intervals and durations of time.
