In this paper, we examine the possible usage of compressive sampling (CS) for the efficient measurement and analysis of floating breakwaters dynamics. We model the dynamics of a box-type floating breakwater in a random sea environment with the Bretschneider-Mitsuyasu spectrum. The spectral method involving FFT and IFFT routines is used for the simulation and CS reconstruction purposes of the displacement and velocity parameters. The time series of forces are calculated using the Morison equation. It is also shown that those vibration parameters can be limited and suppressed to a certain degree by a tuned-mass-damper. The advantages of using the CS for the tuned-mass-damper-controlled vibration parameter measurement and analysis are also discussed. Our findings may provide convenience for the effective and efficient strategies for the vibration-induced problems of floating platforms including wave energy converters and offshore platforms.
