ABSTRACT
Numerical calculation procedures are presented for computing the wave diffraction by surface-p1ercing structures in an ocean of finite depth by the Boundary Element Method. Both direct and indirect boundary elements have been investigated. The more accurate direct formulation is used to calculate the wave interference effects on multiple structures. Comparisons ·between the present results and results available from analytical, source
distribution and finite element methods are good. Therefore, this direct boundary element method provides an alternative calculation procedure for multiple wave interference analysi~. especially when the structures are at some distance apart.
