| As shown in the illustrated electric propulsion control scheme for a twin screw vessel, when the two shaft speeds are within 5% of each other, the bridge may select "shaft synchro-phasing mode". What statement is true regarding the purpose of this operating mode? EL-0168 |
| A) Vibration sensors are used to achieve identical shaft speeds and propeller synchronization to minimize vibration. |
| B) The respective shaft speed sensors alone are used to achieve identical shaft speeds without regard to propeller position to achieve even power development. |
| C) The respective shaft speed and shaft position sensors are used to achieve identical shaft speeds and propeller synchronization to minimize shaft vibration. |
| D) Cavitation sensors are used to achieve identical shaft speeds and propeller synchronization to minimize vibration. |
