Dolphin Gas Project
The Dolphin Gas Project is the natural gas project of the Qatar, United Arab Emirates, and Oman. It is the Gulf Cooperation Council's first cross-border refined gas transmission project and the largest energy-related venture ever undertaken in the region.
Dolphin gas pipeline was conceived in 1999 to produce, process, and transport natural gas from Qatar's North Field to the UAE and Oman.
The project involves:
In addition, the gas supplies from Qatar to Oman are planned through the Al Ain – Fujairah pipeline, which is officially considered as separate project.
The total costs of the project are $7 billion, of which $3.5 billion are costs of the offshore pipeline.
The North Field facilities were designed by Foster Wheeler Sofresid. The first appraisal well was completed in April 2002 and the second appraisal well was completed in June 2002. The offshore platforms were constructed by J Ray McDermott Middle East Inc. The first gas from the wells were produced on 25 June 2007.
Two 36 inches (910 mm) diameter concrete-coated sealines to transport the production stream from the wellheads to the Ras Laffan processing plant were designed and installed by Saipem, a subsidiary of Eni. The 80 kilometres (50 mi) long sealines were laid in 2006.
The Ras Laffan gas processing and compression plant is located at 25°55′31″N 51°30′58″E / 25.92528°N 51.51611°ECoordinates: 25°55′31″N 51°30′58″E / 25.92528°N 51.51611°E. It was designed by JGC Middle East FZE, a subsidiary of JGC Corporation. Ras Laffan is the single largest gas processing plant in the world. The six compression trains are driven by 52 MW gas turbines supplied by Rolls Royce Energy Systems. The plant came on line in 2006 and compresses up to 2 billion cubic feet per day (57 million cubic metres per day) of refined methane gas. The by-products condensate, propane and butane, are sold on spot markets, while ethane is supplied to Qatar Petroleum.
