Rolls-Royce, the global power systems company, has been awarded contracts worth $136m to supply technology and long-term services support to Dolphin Energy Limited, which transports natural gas from Qatar to the United Arab Emirates and Oman via a 364km subsea pipeline.

Andrew Heath, Rolls-Royce energy president, said: "I am delighted that Rolls-Royce technology has again been selected to support the Dolphin Gas Project, one of the largest cross border energy infrastructure projects ever undertaken in the Middle East. The supply of three new Rolls-Royce Trent gas turbines to Dolphin Energy is testimony to the six units already installed on the project. To date, these have recorded over 150,000 operating hours, transporting billions of standard cubic feet of gas to meet the energy needs of the UAE and Oman."

Rolls-Royce will supply Dolphin Energy Limited with three industrial Trent gas turbine compression packages. The three new Trent units, each rated at 52MW, will join six similar Rolls-Royce packages that went into service at Dolphin Energy’s gas processing plant in Ras Laffan, Qatar in 2006.

In addition to selecting Rolls-Royce energy technology, Dolphin Energy Limited has signed a TotalCare long-term equipment service agreement designed to increase equipment availability and reliability.

The equipment will be manufactured and packaged at the Rolls-Royce facilities in Montreal, Quebec, in Canada, and Mount Vernon in the US state of Ohio.

Delivery of the packaged units to Ras Laffan will be in the second and third quarters of 2013.
