The invention discloses a flow debugging method and system for a ship cooling water system, and the method comprises the steps: building a ship cooling water pipe network model, setting data parameters of all parts in the pipe network model and fluid parameters in a pipe network, and calculating a first flow value and a turbulence intensity value; and the appropriate valve opening degree is obtained by judging the turbulence intensity value and the flow value. And the valve opening is applied to an actual ship pipeline system, whether the actual flow conforms to the preset flow range or not is judged, and then the final execution valve opening is determined. Furthermore, reasonable distribution of the flow of the cooling water system can be realized, high-accuracy flow debugging is realized, and insufficient cooling or excessive cooling of mechanical equipment is avoided.
