Question 354General Subjects - Assistant Engineer

The correct answer is D) The thrust direction of the steerable internal duct thruster is determined by the orientation of the water discharge vectoring ring. The thrust direction of a steerable internal duct thruster is controlled by the orientation of the water discharge vectoring ring, which is located at the exit of the thruster duct. By adjusting the position of this ring, the direction of the water jet can be changed, allowing the operator to steer the thrust and control the vessel's movement. The other options are incorrect because they do not accurately describe how the thrust direction is determined in this type of thruster system.
