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, and calculating a first Reynolds value, a flow value and minimum turbulence intensity of the fluid in each section of pipeline according to a set value of the data parameters, a set value of the fluid parameters, a first valve resistance coefficient and a first valve resistance coefficient-Reynolds number relation curve; comparing and judging whether the first Reynolds numerical value and the minimum turbulence intensity value are within a preset range, and acquiring a second valve resistance coefficient of each valve according to the Reynolds numerical value and the minimum turbulence intensity value within the preset range; and according to the resistance coefficient-valve opening degree curve and the second valve resistance coefficient, the actual 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.
