Abstract

In this paper, truncated mooring lines for model tests in various ocean engineering basins are designed with the static similarity. The finite element method based on minimizing of the potential energy is used in order to describe the static statements of mooring lines. The total restoring force induced by mooring lines and tensions at each line are the objective functions for determining the suitable experimental mooring lines. The static offset tests are simulated with variations on the weights in the water, axial stiffnesses, mooring line lengths and mooring line radii. In order to figure out the most similar truncated mooring lines, a simple genetic algorithm is adopted and the usefulness of this method isidentified in terms of the computational time.
