Azipod® electric propulsion

The driving force behind safe, efficient and sustainable operations

Azipod® propulsion is a gearless steerable propulsion system where the electric drive motor is housed within a pod outside the ship hull. Azipod® units can rotate 360 degrees, increasing maneuverability and operating efficiency of vessel, while cutting fuel consumption by up to 20 percent compared to conventional shaftline systems. From its creation three decades ago to its market leading position in global shipping today, Azipod® propulsion has revolutionized marine transport with its unparalleled performance, efficiency, sustainability and reliability.

Key benefits of Azipod® propulsion


   1. Proven ability to reduce fuel consumption by up to 20% compared to traditional shaftline systems

Some of the key reasons why the Azipod® propulsion can save up to 20% of the fuel compared to a shaft line system are:

  • No mechanical losses from a gearless system
  • Pulling propeller in an undisturbed wake field
  • No drag from appendices, rudders etc.
  • Permanent magnet motor technology for maximum output
  • No shaftline system with losses and added resistance
  • Flexibility to optimize hull structure and (5) reduced weight of the vessel

2. Improved safety and redundancy, reduced lifecycle cost
Azipod® propulsion is built to achieve optimal reliability (0.996 availability) and can be delivered with various levels of redundancy, for example double winding, redundant drives and redundant steering system. Safe and flexible operations are enabled by the maneuverability of Azipod® units. The simplicity of the Azipod® propulsion supports limited down time and need for maintenance. Furthermore, the high efficiency of a Azipod® system will support reduced fuel cost and thereby reduce emissions.

3. Vessels featuring Azipod® propulsion are safer: unlike ships using conventional shaftline system, they can be steered throughout the ‘crash stop’ period and take 50 percent less time to come to a complete stop
The tactical diameter is reduced by 40% due to the thrust characteristics of the Azipod® unit. Azipod® propulsion’s steering capability is maintained through the whole speed range of the vessel. Fast acting, the Azipod® system provides easier collision avoidance maneuvers. Crash stop can be reduced by up to 50% by rotation the pods while maintaining positive RPM in a fast and efficient maneuver.

4. Integration of multiple energy sources
As the Azipod® system is a fully electrical propulsion, it is compatible with several types of energy sources of low voltage or medium voltage integration.

5. Seamless integration with power systems and equipment on board
Gearless system limits mechanical losses.

 

   6. Minimized engine noise and vibration

Azipod® propulsion reduces engine noise and vibration due to several factors.

  • There are no noise generation gears
  • Both the pod motor and its shaft are located completely outside the ship hull
  • Pulling propeller receives a steady undisturbed wake field
  • No vibration from a rudder during aggressive maneuvering
  • Noise and vibration from a stern thruster is eliminated

7. Space saved by locating the motor outside the hull allows for more flexible design
Fewer components result in a simpler interface and can reduce the installation costs by up to 20%. The Azipod® system design means less space is required for auxiliary equipment and less height is required in the thruster room. There is no long shaftline. All of this frees up space for the power plant, including engines and generators, which again can enable more payload. Furthermore, by deploying Azipod® propulsion, it becomes easier to develop an optimal general arrangement. The flexible design makes it possible to optimize the hull form.

8. Straightforward and fast installation
A complete thruster exchange can be done in 48 hours. The Azipod® system is designed so that the inboard parts be can installed early and the propulsor later, which gives flexibility and may reduce upfront investment costs for the shipyard.

9. Electric propulsion technology provides a native digital platform. Capability to leverage the digital ABB Ability™ Collaborative Operations infrastructure for predictive maintenance and remote technical support
Azipod® system comes equipped with sensors that can be connected to remote digital monitoring and prediction systems.

10. Azipod® propulsion can be fitted on an existing vessel to replace the traditional shaftline system
The Azipod® system typically frees up space, so it is relatively easy to adapt it to an existing ship in a retrofit project.

Azipod® propulsion in questions and answers


Azipod® propulsion is a gearless steerable propulsion system where the electric drive motor is housed in a submerged pod outside the ship hull.

Azipod® propulsion is available in power ranges from 1MW to 22MW, making it suitable for smaller craftsferriescruise shipscargo carriers and icebreakers capable of independently operating in the harshest conditions. Today, over 25 vessel type rely on the Azipod® technology.

Passenger vessels benefit from the performance provided by 360-degree rotating podded propulsors, high reliability and reduced fuel consumption. Additionally, lower vibration and the flexibility of design allowed by locating propulsion motors outside, rather than inside the hull, prove compelling for passenger vessel owners.

For vessels serving the offshore and energy industries, Azipod® installation requires considerably less space inside the vessel than competing mechanical systems, yielding greater flexibility to optimize vessel design. In addition, optimized installation of thrusters working with a pulling or pushing propeller increases the hydrodynamic efficiency of the vessel and reduces noise and vibrations. Connecting the propeller directly to the propulsion motor eliminates gears and other auxiliary equipment, meaning reduced maintenance costs and less down time due to faults in these systems

Dry cargo vessel benefit from Azipod® propulsion in operations where vessel must perform reliably over an extended period at maximum efficiency, and need to be especially maneuverable in shallow waters. 

For advanced icebreaking tankers and other icebreaking ships, Azipod® propulsion is a true game-changer with unparalleled icegoing characteristics and efficiency.

Icegoing ships powered by Azipod® propulsion can run ahead in open water and astern in heavy ice conditions. This capability allows ships to navigate in ice-covered seas without icebreaker assistance, while keeping higher speeds and consuming less power.


With a much simpler setup than conventional systems, Azipod® propulsion does not require a separate shaftline, rudder, stern thrusters or associated auxiliary systems.
