I’d imagine the pods with electric motors within them would be more efficient than a mechanically driven shaft running down to the pod. There would be a certain amount of power lost through the bevel drive. Great explanation, thank you!

In long term use it more efficient for me than put motor directly to turning propeller. Sealing from sea water will be main issue with underwater motor. Maintenance too will not be a simple work to do.

This design optimizes efficiency by pulling the vessel through water, rather than pushing it, which reduces fuel consumption and enhances maneuverability. Azipods have been notably successful in improving the operational efficiency of ships, cutting fuel consumption by up to 20% compared to conventional system. They are also more powerful than traditional systems.

@@skyfeelan No, azimuth thrusters like the Rolls-Royce Mermaid and ABB's Azipod do not run on batteries. These propulsion systems are powered by the ship's main power supply, which is typically generated by diesel engines or gas turbines. The generated power is converted into electrical energy, which then drives the electric motors located inside the pods beneath the ship. This electrical setup allows the pods to rotate 360 degrees, providing superior maneuverability and efficiency compared to traditional shaft-driven propulsion systems. The electricity for these systems is continuously supplied by the ship's generators, not by standalone batteries. For more detailed operational insights, you might find it useful to visit specific resources or manufacturer websites that provide in-depth technical descriptions and operational guidelines for these marine propulsion systems. They actually more powerful. Please don’t spread lies if you have no idea what you’re talking about. It makes you a bad person and uneducated.

You can forget the rudder refusing to work at low speed, and all the problems with transverse thrust. The pod contains all the moving parts, and all you must take care of, is the quality of the seals. I have no info on how the electric pod propeller behave in case of incidents. Water entering the pod would disable both propulsion and steering of the ship.

From my prospective naval ships are a bit older, on average, and the technology of Azipods is relatively new to them. Military is test, test and test. Changes are in the works so to speak. As far as massive oil tankers go the author is within bounds of reality. Cheaper to get the bump (tug assist). All about the bottom line on profit.

POD propulsion needs high voltage system. Do all synchronous motors used in POD propulsion are slip ring type? I think brushless synchronous can be installed. Secondly may I know why POD propulsion do not gain so much popularity despite of so many advantages? It is well known fact that Deasil electrical propulsion is anytime more fuel efficient then direct diesel drive.

you kind of missed the whole idea and got a bunch wrong, muh hommie. it is cheaper to build a typical single screw propulsion system, but the benefits of a an azipod propulsion system are tremendous. Mainly docking large ships without tug boat assistance and that's with no bow thrusters. There are videos of a little 9 year old girl docking a 100 foot motor yacht by herself, the system uses a single joystick and is incredibly simple to use. They are still studying fuel efficiency so it's too early to claim an advantage in yearly costs and transatlantic cargo shippers are notorious for only using the least expensive method available so single screw cargo vessels will be with us for a while but they may be returning to sails in the future

I dont think that adding a steel ring around a propeller would save it from breaking if you hit something stationary in the move the ships weight is more than enough to rip the pod off the ship if you think about it
