Components of Force Generated by Harmonic Oscillations of Small-Scale Mooring Lines in Water.

Abstract

Linear scaling of deep-water moorings is impractical and reliance must be made by designers on analytic models. To provide a broad data base applicable to model validation, five small-scale mooring line materials were selected for evaluation. The horizontal and vertical components of dynamic tension generated by vertical, sinusoidal motion of the upper end of the mooring line were measured. The experiments were made under conditions of current and no current. Data were reduced to force response ratios as a function of frequency of input, and observations of mooring line motions were made. These response ratios were found to depend on preload, current, bending stiffness and scope.
