Abstract

This paper presents a methodology for determining the wave surface profile and the velocity components of water particles from the wave spectrum of a random sea state to calculate the loads acting on the buoy. For the calculation of mooring lines with attached weights under random loads, the finite element method (FEM) is applied. The parameters of the governing dynamic equations are identified, the Newmark method is used for time integration, and a computational program is developed. The program is verified by comparing the results of the static problem with the dynamic problem under constant loading, demonstrating the correctness of the algorithm and computation. The program is then applied to calculate mooring lines with attached weights for an actual navigational buoy subjected to wind, current, and random wave loads, demonstrating the practical applicability of the proposed approach.
