An industry first occurred recently at Dresser-Rand's world-class manufacturing and test facility in Olean, New York, involving both Rolls-Royce and Dresser-Rand. A full-load, full-pressure performance test for the Dolphin Export Pipeline between Qatar and the United Arab Emirates was completed on a Rolls-Royce TRENT 60 DLE gas turbine and a Dresser-Rand DATUM Model D14 centrifugal compressor — the first time these units have been paired on a compression train.

The ASME PTC10 Type I performance test is the culmination of efforts by Dresser-Rand and Rolls-Royce to design and produce equipment for six export gas compressor trains as part of Dolphin Energy's Dolphin Gas Project in the Middle East. Six mechanical drive Rolls-Royce industrial TRENT 60 Dry Low Emissions (DLE) gas turbines will be used to drive six Dresser-Rand DATUM centrifugal compressors. The project represents the first application of the aero-derivative industrial TRENT 60 engine as a compressor driver.

The test was conducted in May, and included full-pressure testing at over 140 Bar (2000 psi) and 40,000 KW (53,600 hp) to simulate site conditions.

The Dolphin Gas Project is one of the largest energy-related projects ever undertaken in the Middle East. In addition to the development of upstream facilities to extract wet gas from Qatar's North Gas Field, twin sea lines are being constructed to transport the gas to Ras Laffan, an onshore site also in the northern part of the state. Once there, NGL products and condensate will be stripped and the remaining dry gas will be compressed and transported along over 370 kms of sub-sea pipeline to the United Arab Emirates.

Upon completion in late 2006, the Dolphin Gas Project will deliver two billion cubic feet of natural gas a day to the UAE, and is anticipated to supply natural gas to the region for at least 25 years. Three shareholders jointly own Dolphin Energy Limited: Mubadala Development Company, wholly owned by the Government of Abu Dhabi (51 percent), the French company Total (24.5 percent), and Occidental Petroleum of the US (24.5 percent).

In January 2004, Dolphin Energy Limited contracted with the energy business of Rolls-Royce to provide the TRENT 60 gas turbines for the project. Dresser-Rand was selected to provide the high-efficiency DATUM compressors. The TRENT gas turbines were manufactured in Montreal and packaged at the Rolls-Royce facility in Mount Vernon, Ohio. A completed TRENT turbine package was then shipped to Olean to be matched with the DATUM compressor for testing.
