The invention provides a thrust redistribution method under breakdown of a ship dynamic positioning ship propeller. The method mainly comprises the steps: 1, dividing partial faults and complete faults based on different fault degrees, and applying the fault types to thrust distribution; 2, establishing an optimization model in a fault mode based on a maximum thrust fault coefficient method of thepropeller; and 3, determining the thrust redistribution method of the propeller of the dynamic positioning system. A genetic algorithm is selected as an optimization solving method of the control system, and a criterion for solving optimization control distribution is determined. According to the invention, a proper fault model is established for different fault types and degrees. In order to ensure that the ship continues to work safely under the condition that the propelling breaks down, different fault types of the propeller are analyzed, and control distribution parameters of the propulsion system are reconstructed.
