Hotel Service Unit 16 Q5 Quiz

Correct Answer:
C) It can actively adjust water movement in the tanks to counteract any rolling motion

Explanation:
The system’s active control allows it to respond to roll even when the vessel is stationary, unlike passive systems that rely on external water movement.

Correct Answer:
C) Amidships on either side of the vessel

Explanation:
Positioning the tanks amidships ensures effective roll reduction, as this location allows the water movement to counterbalance rolling forces across the vessel’s beam.

Correct Answer:
A) It operates effectively at all speeds, including when the vessel is stationary

Explanation:
Unlike passive stabilizers, which depend on vessel speed, an active system can stabilize the vessel even when stationary, as it actively controls water flow to reduce roll.

Correct Answer:
B) It automatically adjusts water flow based on real-time sensor data on vessel roll

Explanation:
The control system responds instantly to roll sensor data, adjusting water flow to counteract roll by directing water movement within the tanks.

Correct Answer:
C) Gyroscope or inclinometer

Explanation:
A gyroscope or inclinometer senses roll angles and provides data to the control system, allowing it to adjust the water movement within the tanks to counteract roll.

Correct Answer:
B) To reduce vessel roll and improve stability in rough seas

Explanation:
An active tank stabilization system helps counteract rolling by adjusting the movement of water within tanks, thereby enhancing stability.

Correct Answer:
B) By minimizing vessel roll, resulting in a smoother experience during rough sea conditions

Explanation:
Reducing vessel roll enhances onboard comfort, particularly in rough seas, by stabilizing the vessel and providing a steadier environment for crew and passengers.

Correct Answer:
B) To circulate water within the tanks to create a counteracting force against roll

Explanation:
Pumps and valves in the system control the water flow between tanks, using water movement to counteract and dampen roll.

Correct Answer:
A) It increases fuel consumption due to the pumps required for operation

Explanation:
The pumps used to circulate water in response to vessel roll consume additional energy, which can slightly increase fuel consumption.
