Rolls-Royce Trent XWB and Trent 1000 engines will power 12 Airbus A350 XWB and eight Boeing 787 Dreamliner aircraft which are part of THAI's fleet modernisation programme and will further improve the airline's operational and environmental performance.

THAI President Piyasvasti Amranand said: "Our decision to add these extremely efficient Trent engines into our fleet demonstrates our continued commitment to achieve the highest standards of environmental performance across all our operations. This commitment was recently demonstrated with our first biofuel-powered passenger flight, using Rolls-Royce Trent 800 engines."

Nick Devall, Rolls-Royce, Chief Commercial Officer - Civil Aerospace, said: "THAI is an important customer for Rolls-Royce. We are pleased to supply THAI with highly efficient engines which will help the airline achieve its environmental and operational objectives."

When these engines are delivered, THAI will be an operator of every member of the Rolls-Royce Trent engine family: the Trent 500, Trent 700, Trent 800, Trent 900 - as well as the Trent 1000 and Trent XWB.

The Rolls-Royce Trent 1000 powered the 787 Dreamliner aircraft into passenger service for the first time in October and has accumulated more than 75 per cent of the aircraft's flight test hours.

The Trent XWB, the only engine available for the A350 XWB, is the fastest selling Trent ever with more than 1,100 sold. Test results have show the engine to be the most efficient large civil aerospace engine ever produced.

The Trent family of engines has won about 50 per cent of the widebody aircraft market with a firm order book of more than 2,400 engines, and has accumulated more than 50 million hours of service.
