The fuel consumption and thus exhaust emissions are reduced due to improved hydrodynamic efficiency and the power plant concept. Improved hydrodynamic efficiency is a result of reduced hull resistance when traditional shatfline and related brackets can be eliminated and optimum hull design can be utilized. Pulling type propeller is also working in an optimum environment with highest efficiency.

According to the experience from the first cruise vessels with Azipod® propulsion the Carnival Elation, savings up to 40 tons of fuel per week were achieved when compared to her sister vessels with conventional electric shaftline propulsion. A typical value of 10% can be used when estimating the fuel efficiency benefit of a cruise ship with Azipod® propulsion compared to a shaft line concept.

An independent study by marine consultancy Deltamarin revealed that the ABB Azipod® electric propulsion system for ferries could save up to $1.7 million in annual fuel costs per vessel, strengthening Azipod® propulsion’s market-leading position in sustainable marine technologies.By simulating a transit on seven existing ferry routes, researchers found that a ferry equipped with twin 10 MW mid-power range Azipod® units consumed less fuel compared to a similar vessel powered by a traditional shaftline propulsion system. Lower fuel consumption also means that the Azipod®-powered ferry would reduce CO₂ emissions – by approximately 10,000 tons per year. This is equivalent to the amount of carbon dioxide emitted by about 2,200 passenger cars annually.

The power plant concept provides fuel savings by optimizing the loading of the diesel engines. The power management system connects or disconnects diesel generator sets to the network depending on the vessel power requirement, reducing both inefficient low load operation and running hours of the engines.

One of the main sources of vibration is the propeller. The Azipod® unit propeller is a pulling propeller which operates in a better wake field and thus induces lower pressure pulses to the hull. The Azipod® propulsion concept also eliminates the stern thrusters, external shaft supports and rudders. As a result lower vibration and noise levels can be reached onboard the ship which improves passenger comfort.

Since its launch in 1990, Azipod® electric propulsion has become the industry standard for a wide range of vessel segments ranging from smaller crafts to icebreakers capable of independently operating in the harshest conditions.

Offshore segment e.g. drilling rigs, offshore supply vessels, accommodation vessels and pipe layers apply Azipod propulsion technology as an ideal solution due to excellent dynamic position characteristics, reliability and safety aspects.

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 the main reason for the Azipod propulsion selection has been the unbeatable ice going characteristics and the efficiency. Azipod propulsion elevates icebreaking capability and performance to a complete new level. It enables independent ice operation in the harshest environmental conditions with predictable operating schedule, while still minimizing the need of icebreaker assistance. Azipod enables DAS concept, providing up to 50% less installed power and lower fuel consumption ensures economically efficient operation throughout vessels lifetime. 

Azipod propulsion is the most significant example of innovations in passenger segment. Azipod propulsion has become an industry standard in the cruise segment, with the proven ability to cut fuel consumption by up to 20 percent compared to traditional shaftline propulsion systems. Since the first installation over 25 years ago, Azipod® propulsion has saved approximately 700,000 tons of fuel while clocking up close to 15 million running hours at an impressive availability rate of 99.8 percent. For RoPax segment the mid-power range propulsion units have been designed for low onboard height, which allows placing the Azipod® system under the car deck of RoPax vessels, ensuring smooth loading and unloading of vehicles, as well as allowing for maximizing the deck space. The design simplicity of the propulsion system provides increased robustness and reliability, at the same time allowing for ease of maintenance.

Azipod VI propulsion is a unique azimuthing solution for ice applications in power range 6-17MW. With a built-in high-efficiency AC motor and fixed-pitch propeller mounted directly on the motor shaft, it stands out from other thruster solutions. While mechanical thrusters have complex transmission with gears and shafts, the Azipod propulsion has only electrical cables between the power source and the thruster unit. This makes it possible to build an extremely robust propulsion device with the simplicity, strength and reliability for the most challenging ice conditions, and to any ice class.

The Azipod mid-range podded gearless propulsion systems covers three frame sizes in the power range from 7.6 MW to 14.5 MW per propeller, and is based on the straightforward, robust and easy to maintain design principles that have seen Azipod propulsion selected across 25 vessel types over close to three decades. 

These propulsion systems are equipped with ABB’s fourth generation permanent magnet motors that draw on proven Azipod propulsion technologies and have been refined to further increase power and maximize efficiency.

 The mid-power range propulsion units have been designed for low onboard height, which allows placing the Azipod system under the car deck of RoPax vessels, ensuring smooth loading and unloading of vehicles, as well as allowing for maximizing the deck space. The design simplicity of the propulsion system provides increased robustness and reliability, at the same time allowing for ease of maintenance.

In addition to ferry and RoPax vessels, this power range will also be applicable for larger offshore construction vessels, midsize cruise ships and shuttle tankers.

Azipod XO is a propulsion solution for high power open water applications. Azipod XO is available up to 22 MW unit power and it is an ideal choice for vessels like ferries and cruise vessels. Azipod XO brings with it improved energy efficiency, excellent maneuverability and improved passenger comfort.

For fast vessels a Contra Rotating Propeller concept can be formed of Azipod propulsion unit and conventional shaft line by replacing the conventional rudder with an Azipod propulsion unit where the propellers face each other.

Azipod XO is also available with ice classes up to PC 5.

Azipod XL is a high efficiency propulsion unit suitable for high power ships. Compared to Azipod XO the efficiency is improved by installing to the pulling Azipod propulsion unit a special nozzle module including stator blades to straighten the water flow from the propeller to reduce the turbulence and energy loss and to give the optimum thrust for the vessel.  This gives about 5 - 10 % efficiency improvement compared to the exist­ing Azipod XO design. Compared to the conventional shaft line concepts, up to 20 % improvements can be achieved. The efficien­cy is improved over the whole ship speed range and not only at one design point.

Azipod XL design is now available for one frame size, Azipod XL2100, for unit power up to 17,5 MW.

Suitable ship types for Azipod XL are for example LNG tankers, ferries, cruise vessels, offshore construction vessels and tugs.
