The Mooring system design based on Genetic Algorithm

Mooring system design problem is to determine the anchor chain type, length and weight of the ball to make the buoy of the draft depth and swimming area and the angle of inclination of steel drum as small as possible. In this paper, we proposed the mooring system optimization design by mechanical analysis. Because the wind speed on sea surface and sea water velocity direction may not be located in the same plane, so we established three-dimensional coordinate system. And then we deduced the force relation between the objects. Then we regarded the depth, radius and angle of inclination of the winding drums as the optimization goal. By Genetic algorithm we obtain the chain number and length, the quality of heavy ball to make the mooring system under different external conditions (water depth, water velocity and wind speed) safe and stable.
