Rolls-Royce has received an order worth $390m from Thai Airways for Trent 700 engines to power an additional seven Airbus A330 aircraft.
The order also includes a TotalCare long-term service agreement for the aircraft, which will be delivered from 2011.
Rolls-Royce executive vice-president of customer business civil aerospace Nick Devall said the combination of the Trent 700 and the TotalCare support package would offer Thai Airways significant reliability and performance benefits to enhance their operation.
The Trent 700 is the only engine specifically designed for the Airbus A330 and over 1,000 are now in service or on firm order.
