In an azipod propulsion system, how is the azipod unit itself rotated for the purposes of directing the thrust in accordance with steering commands from the bridge?

Correct Answer: Option C — The azipod drive unit is rotated by means of a hydraulic steering unit.

Azimuthing units rely on high-torque hydraulic steering motors acting on a bull gear to swivel the pod assembly according to bridge navigational inputs. 46 CFR Subchapter J and marine safety standards mandate redundant hydraulic positioning for reliable steering control.
