As a passenger on a cruise ship, you may have seen the vessel slowly moving sideways along the dock or while navigating through narrow channels in the port. You might have wondered how a huge ship that weighs thousands of tons can move sideways so effortlessly. Here’s how:
Thrusters
Cruise ships have thrusters that are essentially high-powered propellers that are mounted on the sides of the vessel. These thrusters pump water in a sideways direction, pushing the ship in the desired direction. Most cruise ships have bow thrusters at the front of the vessel and stern thrusters at the rear. The thrusters can be used to move the ship both backward and forward as well as sideways.
The ship’s captain and crew can control the thrusters separately, allowing the ship to move in any direction they want. The onboard computer system calculates the amount of thrust required to enable the ship to move sideways. This system can also make minor adjustments in the thrust to keep the ship parallel to the dock when berthing.
Azipod Propulsion System
Another way that cruise ships can move sideways is by using an Azipod propulsion system. This innovative system comprises an electric motor that is located directly on the underside of the ship’s hull. It is positioned horizontally instead of vertically, like a traditional propeller. The system can rotate 360 degrees and can provide enough propulsive force to move the ship in any direction, including sideways.
The Azipod propulsion system is highly efficient, and it can provide better maneuverability and fuel efficiency compared to traditional propulsion systems. This system also reduces noise and vibration, making the cruise more enjoyable for passengers.
Moving a large cruise ship sideways requires a great deal of precision and expertise. The ship’s crew must use the onboard technology and high-powered thrusters to control the vessel’s movement while keeping it parallel to the dock. With the right equipment and a highly skilled crew, cruise ships can easily move sideways and navigate narrow waterways to the delight of their passengers.
