Combined diesel-electric and gas turbine (CODAG) propulsion
A hybrid machinery system with a gas turbine and diesel engines driving generators to create electric power for both propulsion and the hotel side. See also CODAG propulsion system of CORAL PRINCESS.
The vessel is driven by four Mermaid pods. The 117,200kW CODAG installation is supplied from four 16,800kW Wärtsilä/ABB diesel alternator sets, supplemented by the output from two alternators with 25,000kW General Electric gas turbine drive. The diesel installation produces some 57% of power requirements, with 43% derived from the gas turbine sets.
