ABB is set to launch a new Azipod propulsion unit that the company claims is up to 10% more efficient than previous versions.
Azipod propulsion is the shipping industry’s leading podded electric propulsion system and ABB believes the improved efficiency and bollard pull will expand its appeal beyond established strong markets, into new sectors such as LNG carriers.
The new linear flow Azipod XL introduces a nozzle with stator plates, which directs the water flow from the propeller to reduce the turbulence and energy loss and to give the optimum thrust for the vessel.
Azimuth propulsion works by drawing water into the propeller and pulling the vessel. As such, the addition of a nozzle will optimise the water flow as it leaves the propeller. All the improvements have been tested extensively using scaled versions in laboratory conditions.
Juha Koskela, Managing Director of ABB’s Marine and Ports business, said: “Azipod propulsion is widely used in the cruise industry and on many complex specialised offshore vessels […] However improved fuel efficiency and bollard pull of the Azipod XL will increase its competitiveness into new sectors such as tugs, ferries and LNG tankers.”
The Azipod XL concept can be designed to give high bollard pull thrust at lower speed and still have good characteristics at higher speeds. This improved performance along with better fuel efficiency makes the Azipod XL suitable for a wider range of vessels.
