Oasis of the Seas did not look to be connected to shore power, based on the steady stream of exhaust coming from one of its stacks. The Ship has massive Power requirements.

The ship’s power comes from six medium-speed, marine-diesel generating sets: three 16-cylinder Wärtsilä engines producing 18,860 kilowatts each and three similar 12-cylinder Wärtsilä engines producing 13,860 kilowatts each. The fuel consumption of the 6 engines at full power is 7,230 us gal/hour. The total output of the engines, 97,020 kilowatts, is converted to electricity, used in hotel power for operation of the lights, elevators, electronics, galleys, water treatment plant, and the other systems onboard, as well as propulsion.

Propulsion is provided by three 20,000-kilowatt (26,800 hp) Azipods Docking is assisted by four 5,500-kilowatt bow thrusters.
