Abstract (en)
[origin: EP4067221A1] A ship propulsion device (1) includes three or more propulsion units (11), a malfunction detection unit (12a), and a control unit (12). The control unit (12) controls the three or more propulsion units (11). The three or more propulsion units (11) are disposed with left-right symmetry. When a malfunction is detected in any one of the three or more propulsion units (11) by the malfunction detection unit (12a) while the three or more propulsion units (11) are operating, the control unit (12) stops the propulsion unit (11) in which the malfunction has been detected, and, on a left side and a right side of a hull, stops at least one propulsion unit (11)¥ of the propulsion units (11) disposed on the side opposite from the side on which the propulsion unit (11) in which the malfunction has been detected is disposed.
