ANALYSIS OF FLOATING BREAKWATER MOORING FORCES

A method for analyzing floating-breakwater effectiveness and mooring forces is presented. The mooring-line analysis is based on static equations and is included as a restoring-force term in the equations of motion for the breakwater. Results of the theoretical analysis are compared with model experiments and data obtained in the field. The theory consistently under-predicts mooring forces indicating that further refinement of the analysis is required. Evidence of long-period oscillations in the mooring forces is also presented and discussed.
