The invention relates to a ship fouling monitoring and evaluation method based on an overall fouling coefficient, belongs to the technical field of ship fouling treatment, and solves the problem thata fouling monitoring method is not accurate enough. The method comprises the following steps: acquiring navigation data of a to-be-evaluated empty/full-load navigation section; based on the navigationdata of a to-be-evaluated no-load navigation section, acquiring a power-navigation speed relation curve of the no-load navigation section, acquiring a fitting power-navigation speed relation curve ofthe no-load navigation section in combination with a fitting model, and calculating an overall fouling coefficient of the to-be-evaluated no-load navigation section in combination with a power-navigation speed reference data matrix under a no-load working condition; and based on the navigation data of the to-be-evaluated full-load navigation section, acquiring a power-navigation speed relation curve of the full-load navigation section, acquiring a fitting power-navigation speed relation curve of the full-load navigation section in combination with a fitting model, and calculating an overall fouling coefficient of the to-be-evaluated full-load navigation section in combination with a power-navigation speed reference data matrix under a full-load working condition. The fouling state is quantitatively analyzed in real time on the whole, and the accuracy of an analysis result is improved.
