Abstract:Based on the traditional catenary mooring, a new mooring system with submerged buoy is proposed. Genetic algorithm is used to optimize the length and weight of the new mooring line to keep the pretension, horizontal span, as well as the length of line resting on the seabed consistent with the traditional catenary mooring. To illustrate the validity of this new system, the static and dynamic characteristics are studied and compared with that of traditional catenary mooring. The piecewise extrapolating method is employed to solve the static problem. The dynamic analysis is executed through time-domain nonlinear finite element method accounting for the sinusoidal oscillations of the moored floating platform. The specific results would be helpful for the design improvement of deep water mooring system. Copyright ? 2016 by the International Society of Offshore and Polar Engineers.
