The invention relates to a ship bottom fouling monitoring and evaluating method based on a fixed navigational speed bottom fouling coefficient, and belongs to the technical field of ship bottom fouling treatment. The method solves the problem that a bottom fouling monitoring method is not accurate enough. The method comprises the steps of acquiring ship navigation data of a route segment in a to-be-evaluated time period, and preprocessing the ship navigation data; based on the preprocessed navigation data, obtaining navigation data of no-load/full-load route segments to be evaluated; based onthe navigation data of the no-load route segment to be evaluated, obtaining a power-navigational speed relation curve of the no-load route segment to be evaluated, and calculating a fixed navigation speed bottom fouling coefficient of the no-load route segment to be evaluated by combing a power-navigational speed reference data matrix under a no-load working condition; and based on the navigationdata of the full-load route segment to be evaluated, obtaining a power-navigational speed relationship curve of the full-load route segment to be evaluated, and calculating a fixed navigational speedbottom fouling coefficient of the full-load route segment to be evaluated by combining a power-navigational speed reference data matrix under a full-load working condition. Real-time quantitative analysis of a bottom fouling state is realized, and the accuracy of an analysis result is improved.
