Do Cruise Ships Use Gyroscopes?

Cruise ships use various stabilizing systems to maintain stability and manage weights. These systems include active fins, gyroscopes, and active moving weight systems. Active fins use a roll sensor to convey the roll angle and velocity to an external controller. However, most large cruise ships do not use gyroscopic stabilizers due to their heavier weight. To control the rolling, a gyroscope must be large enough to control the ship’s motion.

Stabilizers work by countering the forces that cause the ship to roll, effectively minimizing the degree of motion and reducing the likelihood of seasickness. They also play a crucial role in maintaining the ship’s stability. The third type of stabiliser used on modern cruise ships is a gyroscopic stabiliser. These state-of-the-art fin systems can be adjusted by an onboard control system according to prevailing conditions. When the gyroscope senses the ship’s roll, it changes the fin’s angle of attack so that the forward motion exerts force to counteract the roll.

Finally, all modern cruise ships have stabilizers, with most having two on each side of the ship. Larger ships like Cunard Lines Queen Mary 2 and Royal Caribbeans Voyager have two stabilizers. Examples of active stabilization systems include active fins, active anti-rolling tanks, active moving weight systems, and the gyroscope.

Despite their importance, passenger ships may not use them much due to the drag they cause. Most modern passenger ships use hydraulic stabilizers, which stabilize the ship with the aid of a gyroscope.
