The invention discloses a flow velocity debugging method and system for a ship oil system. The debugging method comprises the following steps: constructing a pipe network model of the ship oil system; setting data parameters of internal parts of the pipeline model, acquiring a first Reynolds value and minimum turbulence intensity, comparing the first Reynolds value and the minimum turbulence intensity with a preset range, and judging and acquiring a second valve resistance coefficient of each valve; according to the resistance coefficient-valve opening degree curve and the second valve resistance coefficient, the first valve opening degree is obtained; the first valve opening degree is applied to an actual ship pipeline system, and an actual flow value is obtained; and whether the error value between the actual flow value and the model flow value corresponding to the first valve opening degree is within a preset error range or not is judged, so that the final execution valve opening degree is obtained. The oil flow speed of a pipeline system is simulated and debugged, it is guaranteed that all pipelines efficiently complete oil flow string washing, and the problem that the later real ship oil throwing string washing period is too long is solved.
