Title:
SHIP PROPULSION SYSTEM AND SHIP
Document Type and Number:
Japanese Patent JP2023068838
Kind Code:
A
Abstract:
To provide a ship propulsion system and a ship that can enhance position holding accuracy in controlling drift, while minimizing an environmental load accompanying driving of propulsion machines.SOLUTION: A ship propulsion system 102 of the invention includes: a main propulsion machine 1 configured to be able to change a direction of thrust by turning laterally; an auxiliary propulsion machine 2 which includes an electric motor 23 for driving an auxiliary propeller 20 generating thrust, and is capable of changing a direction of thrust by turning laterally; and a control section 6 for controlling drift by moving a hull 101 when an external force F including flows of wind and water is received, while maintaining an orientation of a bow 101a of the hull at a target orientation T2 by turning round the hull. The control section 6 is configured to maintain, in controlling drift, an orientation T1 of the bow 101a at a target orientation T2 by driving the auxiliary propeller 20 to turning round the hull 101 in a state that a main propeller 10 generating thrust of the main propulsion machine 1 is halted.SELECTED DRAWING: Figure 1
