A parametric analysis of dissipation capacity for \pi-type floating breakwaters

Aims of this work are to investigate the influence on wave energy dissipation for a ?-type floating breakwater, according to nondimensional variables. The related FB dissipation coefficient distributions are examined with respect to two parameters: the first one is a geometric approximation of the wave period scaled with the heave natural motion period of the FB; the second is the wave steepness. A Monte-Carlo based error analysis is carried out in order to evaluate the amount of error propagation involved in the derivation of dissipation coefficients. Results show that the two invoked parameters appear to be the key for the description of the multiple processes here involved.
