What it Takes to Manufacture Million $ Propellers Moving World’s Largest Ships

Welcome back to the our channel for a discussion about how giant ship propellers are manufactured, cleaned, and protected from the ocean’s elements. That's one of the most fascinating things I've ever seen on video. A ship's propeller in motion under the water. And in such crystal clear water too. Beautiful footage, too bad it doesn't always coincide with the dialogue. I'd think blades on variable pitch props could rotate 360 degrees (they can't) if I hadn't worked on them. Scary stuff being down next to those blades. A simple miscommunication can easily cause a life to be lost if those things start up while anyone is still underwater and close to them! I thought we would see some super huge CNC's milling the props! Basically skipped that part. Most large ships use electric motors to power the propellers like in those azimuth thrusters. Kind of strange they didn't talk about that at all. Otherwise very interesting video.
