A computer program, originally developed to predict wave loads on large‐diameter fixed offshore structures, has been modified to compute added masses, damping coefficients and response motions of free‐floating and moored rigid systems. It is now being extended to predict multi‐degree‐of‐freedom responses of articulated structures, particularly wave energy absorbing devices. The structure is modelled by surface singularities (point sources) in potential flow. The boundary conditions, fluid and structure equations of motion are linearized. Engineering applications here include the predictions, fluid and structure equations of motion are linearized. Engineering applications here include the prediction of wave loads on a gravity platform, response motions of a moored barge, and comparisons with laboratory data on the mooring loads and response of a tethered buoyant platform, and on the wave loading, response and efficiency of two wave energy absorbing devices.
