Numerical Investigation of Large Nonpowered Ships Anchor Chain Mooring Force in Extreme Offshore Environment

Nonpowered vessles can't self-propelled and initiative resist wind and stream. Single point buoy mooring system is one of effective ways for nonpowered vessle to mooring in extreme offshore environment. Based on wind, flow and wave model, the bow anchor mooring force model can be achieved. Through compared with physical model test data, the scientificity and rationality of the mathematical anchor chain mooring force model of single point buoy is verified. Then the design of nonpowered vessle buoy engineering is analyzed by the means of single point buoy mooring system mathematical model.
