In order to study the influence of both buoy position and buoyancy on capability of anti-disturbance for floating structure catenary, the mathematic model of multi-component catenary was established by using piecewise extrapolation method. With consideration of current forces and elastic extension, the variation trend of catenary length and top horizontal tension changes following buoy position changing with same preload was derived. By analysis of moving response of the platform under different buoy positions and same disturbance, the optimum buoy positions at a disturbing force were determined. Then the buoy with different size were selected to change the buoyancy for studying the influence of buoy on catenary top displacement and its length under fixed disturbance, in result, the optimum buoy sizes at optimum positions were derived. The results can provide a reference for the configuration of the catenary in moored positioning system.
