Mobimar and STX Europe have signed a contract on the build-up of propulsion systems area for the two Oasis class cruisers.  Contract for these so called Azipod equipment rooms is regarded as a turn-key delivery. Launch of the first vessel (Oasis of the Seas)  is 2009 and the second vessel (Allure of the Seas) sets its sail in 2010. Mobimar has built similar systems to Voyager class cruisers between 1999 and 2003.

Azipod is a electric propulsion system for ships and it is a trademark of ABB. The Azipod unit is fixed outside the ship in a pod, or casing, which combines the functions of a propulsion motor, main propeller, rudder and stern thruster. These traditionally separately installed units are no longer needed, vacating space on board for other purposes.

The Azipod system arrangement in a cruise vessel has been shown to reduce fuel consumption by about 10 percent when compared to diesel-electric propulsion systems with a conventional shaft-line arrangement.
