ANALYTICAL DETERMINATION OF STRUCTURAL LOADING ON ASR CATAMARAN IN BEAM SEAS

A two-dimensional model which incorporates the effects of wave diffraction and body motion has been developed to predict the dynamic structural loading on the crossbeam of a catamaran with zero forward speed in beam seas. Theoretical and model experimental results are compared for the amplitude of the bending moment and vertical shear acting at the midpoint of the crossbeam of the ASR catamaran, a Navy submarine rescue ship. Correlation of theory with experiment is confirmed over the important frequency ranges.
