The engineering on board of Harmony of the Seas is reliable, strong and environmental. The main engines are four Wartsila 12V46F, each with power of 19,300 hp, as well as two Wartsila 16V46F, each with power of 25,700 hp. The total output power of the vessel is 128,800 hp. The propulsion is provided by three 20 MW ABB Azipod, which allow operating with service speed of 22.0 kts, while the maximum achieved speed is 25.0 kts. Also on board are installed four 5.5 MW Wartsila CT3500 bow thrusters. Harmony of the Seas is 20% more energy efficient than her sister ships. Small air bubbles from the keel reduce drag and thus fuel consumption by 7-8%, and a smooth hull surface further reduces resistance. The bubble system also reduces propeller noise, which improves the comfort of the passengers. The LED and fluorescent lamps replace incandescent light bulbs, reducing power consumption and need for air conditioning. The engine system uses a waste heat recovery system, and drives three Azipod propellers.

Harmony of the Seas is operating under the flag of Bahamas with IMO number 9682875, MMSI 311000396 and call sign C6BX8.
