Aiming to a twin-screw sightseeing ship with the power supplied by solar and lithium batteries and propellers driven by brushless DC motors, a simulation model of the ship movement is established in the case of both rudders failure. By detecting rotation speed of the propellers on port and starboard, equivalent values of rudder angle are calculated in real-time with the difference between the two speeds, and an appropriate speed controlling value of propeller is given. Maneuvering control strategy is optimized under the condition of rudder failure, and then the control system is simulated. The simulation results show that the proposed control strategy is effective and practical, and both ship maneuvering and safety performances are improved.
