Question 519Electricity & Electronics - Assistant Engineer

The correct answer is C. The azipod drive unit is rotated by means of a hydraulic steering unit. In an azipod propulsion system, the azipod unit itself needs to be rotated in order to change the direction of thrust in accordance with steering commands from the bridge. This rotation is achieved through a hydraulic steering unit, which uses hydraulic power to physically turn the azipod unit as needed. The other options are incorrect because pneumatic systems, electro-mechanical systems, and synchronous transmission systems are not the typical means of rotating the azipod unit for steering purposes. Hydraulic steering is the industry standard for azipod propulsion systems.
