    A new type of steel floating breakwater, which is comprised of a box-type pontoon and truss structure, was designed for incident waves to be broken efficiently by the front truss and for the pontoon to suppress the transmission of the small broken waves. The performance of wave absorption is investigated by changing systematically the experimental parameters and the dimension of the floating breakwater. The transmission coefficients are normalized by introducing a representative dimensionless parameter, and a universal expression for the transmission coefficients is obtained. The relationships between the introduced representative parameters and the dimension of the breakwater or the wave parameters are investigated with the aid of a dimensional analysis. The universal expression for the transmission coefficients and the quantification of the representative parameter enable us to estimate the transmission coefficients of the steel floating breakwater constructed in an arbitrary sea area.
