heal.abstract	The present study tackles the problem of random wave diffraction through an opening between two breakwaters forming an arbitrary angle. The numerical scheme used is result-oriented and employs the solution regarding the diffraction coefficient k for the monochromatic case. The study comprises two parts, the first dealing with uni-directional and the second with multi-directional incoming spectra. A simple energy conservation principle applied to a number of components associated with the monochromatic solution of the diffraction problem, produced one-dimensional spectra of the diffracted waves at any point in the lee of the breakwaters. A compound diffraction coefficient K could thus be established in terms of the k's and the characteristics of the incoming spectrum. Graphs of equal K-values are presented for the various cases examined. The second part of the study deals with waves presenting spatial distribution of energy. A directional spreading function of the Mitsuyasu-type was assumed. The diffracted spectra yielded a composite diffraction coefficient by integrating through the directions as well as through the frequencies.	en
