Ships are no different than your car, truck, boat, airplane,or anyother mechanical device. They all need repairs from time to time. They all need maintence from time to time.
I'm surprised how well they keep these ships looking and operating. And being in the ocean 24/7, 356 days a year, its even more remarkable.
Azipod, is what propells the ship through water. There also used to turn the ship.You ever wonder how they can place a ship as large as the Conquest in-between 2 other huge ships? They use the pods to place the ship into tight areas.
happy cruising to all;
