The invention relates to a simulation verification method for adsorption performance of a ship magnetic mooring column. The method is characterized by comprising the following steps: S1, determining basic parameters; S2, determining the position of a magnetic mooring column; S3, verifying the adsorption force and the installation position of the magnetic mooring column; The adsorption force of themagnetic mooring column is determined according to the gravity action of the accommodation ladder and the centrifugal force generated by ship rolling; the state of the full load condition of the accommodation ladder at the multi-angle position is verified under the adsorption force, and the distance difference between the accommodation ladder and the ship body before and after full load is verified through a simulation test to judge whether the installation position of the magnetic mooring column and the adsorption force meet the requirement or not; The simulation verification method can greatly reduce the construction amount of a shipyard and is suitable for verification in various water areas.
