A description is presented of a three-dimensional model investigation to evaluate a design for the Atlantic Generating Station, which consists of two nuclear power plants mounted on floating platforms and protected against wave action by an encircling breakwater. The primary study objectives are to evaluate: platform motions, mooring strut forces, breakwater stability, platform hull pressures, wave field, near-field thermal effects and effects of a tanker collision on the breakwater. The investigation consists of a small scale (1:196) model and a large scale (1:64) model. Comprehensive results of platform heave, pitch and roll determination are available for the small scale model over the expected range of wind-generated wave periods. These results indicate the most critical design conditions in terms of: wave direction, period, and height. Of particular interest is the relative absence of strong resonant peaks in the normalized responses for heave, pitch and roll.
