The CORAL PRINCESS built in 2002 at Chantier de l’Atlantique is P&O first CODAG cruise liner. This machinery and propulsion system brings together a General Electric 25,000kW gas turbine located in the funnel and driving an alternator and two 16,200kW diesel-alternators fitted in the main machinery room and using Wärtsilä prime movers.
The three alternators supply power to two main switchboards and twin 20,000kW Alstom variable speed propulsion motors. These drive FP propellers in an arrangement, which provides 50% redundancy in case of fault, with back-up electrical supply available from two 1080kW diesel-alternators sets.
