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.
@@isabellam1936 I stand corrected, yeah, I made a mistake when I wrote that comment (I don't meant to spread misinformation, I just like to answer thing) several months later, I learned about diesel-electric train, which work on the same principle just like you described and it finally clicked to me
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.
Yeah, that's a interesting fact which they conviniently forgot. Both steering and propulsion wi ll be lost in the event of a mishap. Certainly not worth the advantages of using it.
This is totally amazing. 👍 Just one thing, why is it better to pull the 🚢 rather than push? And I heard this Propulsion system, Design and Configuration is going to be put on TITANIC. Still an interesting thing. Please and Thank you.
So, does this virtually eliminate the need for a wheelman? The captain can simply control the direction of the azipods, with no need for a conventional rudder.
Because of the expenses of fitting the ships with them, instruct the crew about the how they work, maintenance and so on. Cargo ships are made to bring money not to increase expenses.
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.
Higher capital costs Diesel-electric system required (power loss). Power requirement higher for single screw arrangements. Limitation in power. Limitation in speed.
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
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
You’re wrong. Azipods have been notably successful in improving the operational efficiency of ships, cutting fuel consumption by up to 20% compared to conventional system.”
Diesel motor > generator > VSD > electric motor > gear >prop Now there literally no way on earth it's more efficient than motor attached to propeller without a reduction gear.
Great.
You impart amazing knowledge from time to time.
Keep it up!

electric motor will be severelyy underpowered, not to mention you have to carry battery

@@rv_316 And still all the navies and corporations are going there so it must be more efficient.
Thanku for the amazing content. Add more ship related videos, it will be useful for us.
Thank you Vinod. Sure we will. Do subscribe to our channel
Regarding the properties of moving water, not aerodynamic, hydrodynamic.

Glad to hear the video was helpful!
Variable pitch propeller. Can the Azipod be equipped with them at nominal cost and are they effective?
All this and nightmares too. Thanks.
Great insights ! what are the disadvantages???
Very informative
Thank you. Please do share and support 👍
can we use locomotive traction motors? I am mean same traction but bigger in size..making a replika making it bigger..
So, does this virtually eliminate the need for a wheelman? The captain can simply control the direction of the azipods, with no need for a conventional rudder.
How sealing is made here like stern tube sealing?? Please make video for Contra rotating propellers
What about Wartsila ?
Thnx for the information
Welcome. Please do share and support
What is the tonnage limit that electrical pods can move? I ask this question because a 400,000 ton ship may not be able to move it. Thanks. like
Thx for the info. I have 2 questions
1. Why do most naval ships not use azipods?
2. Why don't cargo ships or oil tankers use azipods
Because of the expenses of fitting the ships with them, instruct the crew about the how they work, maintenance and so on. Cargo ships are made to bring money not to increase expenses.

Yes, Burshless motors are alos used.
Diesel electric propulsion coupled with POD has higher power loss as compared to direct drive system
are those fitted backwards??? With the Properllers pointing forwards? to the bow?
Yes, they are fitted at the aft.
The pod which carries the propeller can be rotated 360 degree
How much does Azipod propulsion systems cost on an icebreaker?
I love this content
Glad to know that 👍
Do you have shown how to drop anchor and lift the anchor
Very informative ❤️
Glad it was helpful!
Do you still need tug boats as much while docking .
Hi
Please produce a video about AtoN buoys production process
Thanks
Is there any disadvantage of this pod propulsion???
Higher capital costs
Diesel-electric system required (power loss).
Power requirement higher for single screw arrangements.
Limitation in power.
Limitation in speed.
@@marineinsight Can you please elaborate the limitation in power and speed please
What should be the operational switching frequency of it?
Sir, please upload videos for azimath steer drive am working on this type vessel, i dont have a idea
The excellent system
👍
If Titanic have those engine would they avoid iceberg effective than 3 screw with tiny rudder?
Ship with such technology can still collide and sink :)
How asipod propulsion will reduce Manning in merchant Navy?
IT won't
How much does a Pod add to the draft of the ship?
That’s a great question! You wouldn’t want to run aground with this type of propulsion!🤣
Did not know that bottom fin on azipod is for better AEROdynamics in water
Bravo
Thank You Benod for the support and comment.
How the Steering system is replaced in the azipod system?
Azipod doesnt need a steering system since it can steer by turning itself
Then why is it not widely used ?
Engineering room 😊
usefull
First cruise ship ever made with pods was Carnival Paradise not Elation.
Thank you for the insight
So many errors in this youtube-clip
Why aren't actual propellers protected from underwater obstacles
Some Propeller do have a circular covering
Adding protection to the screws also adds drag, reducing efficiency.
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
In Germany we call it schottel, because the only company making these is schottel

We are not sure either 🤷🏼
Diesel motor > generator > VSD > electric motor > gear >prop
