Rolls-Royce has won its largest ever order, worth $9.2bn, to provide Trent 900 engines and TotalCare® service support to Emirates. The engines will power 50 Airbus A380 aircraft that will enter service from 2016.
The decision confirms the Trent 900 as the engine of choice on the four-engine A380. It has now secured more than 50 per cent market share on the aircraft, in addition to being selected by the majority of A380 customers.
John Rishton, Rolls-Royce, Chief Executive Officer, said: “The success of Emirates over the last thirty years has been extraordinary; this is in no small part thanks to the exceptional leadership of Sir Tim Clark. Rolls-Royce has been proud to have been part of this success, powering Emirates aircraft since 1996. We are delighted that Emirates has again placed its trust in our technology, with the biggest order in our history.”
Sir Tim Clark, Emirates Airline, President, said: “Rolls-Royce is a key partner for Emirates and we have been impressed with its commitment to continual improvements in the economic and operational performance of the Trent 900. These improvements have been decisive factors in our selection of the product for 50 of our A380s. Today’s announcement is significant not only because it cements the partnership between Emirates and Rolls-Royce, but also because of the significant economic impact that this will have on aviation manufacturing in the UK and Europe.”
The Trent 900 powered the first commercial A380 in 2007 and is now used by eight operators on more than 70 aircraft, having logged over 4 million in-service flight hours. The engine offers the lowest lifetime fuel burn, with the latest version including technology developed for the Trent XWB and Trent 1000 engines.

A new family of medium speed diesel engines producing 600kW per cylinder maximises the integration of today’s technology to reduce operating costs.
Developed to be more powerful and efficient as well as extending service intervals, the new Bergen B33:45 harnesses today’s technologies to the full.
The ship designer and shipyard can use to advantage the new engine’s compactness and ease of installation.
The new B33:45 comes with a 20 per cent increase in power per cylinder compared with current B-series engines.
Bore is 330mm and stroke 450mm. CFD analysis of the combustion process was undertaken together with the MTU R&D centre in Friedrichschafen.
In-line engines are the first to be produced, with V engines to follow later. In-line six, seven, eight and nine cylinder units span a power range from 3,600 to 5,400kW and V engines 6,000 to 8,400kW.
Specific fuel consumption is 175g/kWh at 85 per cent MCR and 177g/kWh at full load.
The engine control system is the electronic engine management system from MTU which is developed in-house. It monitors and controls all key engine functions and exhaust aftertreatment.
A totally new turbocharger is matched to the exhaust system which provides multi-pulse charging with charge air taken through a two stage intercooler, which gives a high turbo efficiency. Modular design has been applied throughout for ease of maintenance.
Looking more closely at the design of the B33:45, the foundation is a more rigid SG iron block than the current B-series, which has reduced vibration levels to 10-11m/sec. It supports the balanced crankshaft which is the same for both propulsion and generator applications. Cylinders are individual units that can be removed complete within a service height of 2.52m above the crankshaft centre-line. Connecting rods are of the marine three-piece type allowing piston removal without disturbing big end bearings. The strengthened camshaft design has one section per cylinder for ease of replacement.
Another feature is a reduction in the amount of external pipework, that ensures a safe, yet simple fuel system design. This has been achieved by putting the oil bores into the cylinder heads and the passages are joined by simple transfer blocks. The system is common rail ready, with the conventional system providing maximum flexibility for different applications.
Meeting IMO Tier III NOx emission requirements was another important goal and is achieved with selective catalytic reactor (SCR) technology. The system uses urea to convert the NOx into nitrogen and water vapour. An SCR system was part of the development programme and NOx levels within IMO levels have been successfully validated running from 10 – 100 per cent load. The control unit is integrated into the engine controller and compact SCR units will come in various sizes to match the engine power selected.
The B33:45 family is designed for 25,000hrs between major maintenance when operating at average loads within a specified window. This enables major engine maintenance to be alined with the vessels reclassification intervals, normally every five years, which significantly reduces vessel down time. When overhauls are finally needed owners can benefit from the Bergen worldwide exchange pool system which offers cylinder heads, injection components and other parts by exchange and later return, with warranty.
The engine control system is the electronic engine management system from MTU which is developed in-house. It monitors and controls all key engine functions and exhaust after treatment.
