Abstract
  • This report describes the hydrodynamic testing and evaluation of a one-tenth scale model of the FMC Wave Attenuation Device. The purpose of the test was to quantify the wave attenuation characteristics and structural loading induced by a test program of monochromatic incident waves on the submerged structure. The device was tested to failure. The attenuation characteristics of the model were found to be frequency dependent with minimum transmission coefficients (0.4) and maximum reflection coefficitions (0.5) occurring at a wave period of 7.1 seconds prototype. The structure response of the model, as monitored by induced loads, stress and deflection were found to be more dependent on wave height. Yield stresses were exceeded in the duct plate under severe wave conditions and very large uplift forces were noted. The general model behavior was found to correlate well with known kinematic conditions for the incident wave. Structural deflections responded in a restrained circular motion, closely following the water particle orbital motion under a simple wave.
