The invention provides a thrust distribution method under a ship propeller fault mode based on an improved parrot algorithm, and belongs to the technical field of dynamic positioning ship thrust distribution. According to the technical scheme, the method comprises the following steps that 1, various parameters of a ship are initialized; step 2, constructing a thruster equality constraint term; 3, initializing parameters of the improved parrot optimization algorithm; 4, performing individual variable updating by applying an improved parrot optimization algorithm; 5, judging whether the maximum number of iterations is reached or not, if so, executing the step 6, otherwise, executing the step 4; and 6, outputting a thrust distribution result, updating ship state parameters, and skipping to the step 2 to carry out thrust distribution calculation of the next cycle. The method has the beneficial effects that the method has good algorithm optimization ability in both the failure mode and the non-failure mode of the ship propeller, the thrust optimal solution can be quickly and reliably obtained, and the ship thrust distribution performance is improved.
