The Dolphin Gas Project
is the natural gas project of the United Arab Emirates
. It is the GCC
'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, in order to support long-term industrial growth.
The project involves:
- development of gas wells and installation of two platforms in Qatar's North Field;
- two multiphase sea lines from the wellheads to the processing plant;
- gas processing and compression plant at Ras Laffan in Qatar;
- offshore pipeline from Ras Laffan to Taweelah in the UAE;
- gas receiving facilities at Taweelah.
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 US$7 billion, of which US$3.5 billion are costs of the offshore pipeline.
North Field facilities
The North Field facilities were designed by Foster Wheeler Sofresid
. The first appraisal well s 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 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 the Eni Group
. The 80-kilometers long sealines were laid in 2006.
Ras Laffan processing plant
The gas processing and compression plant at Ras Laffan was designed by JGC Middle East FZE, a subsidiary of JGC Corporation of Japan. The six compression trains are driven by 52MW gas turbines supplied by Rolls Royce Energy Systems of the UK. The plant came on line in 2006 and compresses up to 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
The offshore pipeline from Ras Laffan to Taweelah in the UAE (export pipeline) was designed by Saipem, and the pipes were supplied by Mitsui
of Japan. The pipeline has capacity of 33 billion cubic meter (bcm) of natural gas per annum. The construction of the pipeline was objected by Saudi Arabia
because of the border dispute between Saudi Arabia and the UAE, however the pipeline was built.
Taweelah receiving facilities
The gas receiving facilities at Taweelah were constructed as adjacent to the Taweelah Power Station and comprise three parallel gas-receiving trains and associated equipment, metering facilities, control buildings and warehouses and interconnecting pipelines to the Taweelah Power Stations and to the existing Maqta-Jebel Ali Pipeline. The facilities were designed by Technip of Abu Dhabi and Al Jaber Energy Services Consortium of the UAE. The construction were completed in 2006.
Al Ain – Fujairah gas pipeline
– Fujairah pipeline is a long natural gas pipeline with capacity of 20 bcm of natural gas per annum. The pipeline was constructed in 2003. In 2004-2005, the pipeline was operated by the Emirates General Petroleum Corporation (Emarat), and since 2006 by Dolphin Energy. Until 2008, the pipeline is used for supplying Omani natural gas to the Fujairah power and desalination plant
. Starting from June or July 2008, the pipeline will be used for natural gas export from Qatar to Oman.
Taweelah - Fujairah gas pipeline
The Taweelah - Fujairah pipeline is a planned long pipeline between Taweelah gas receiving facilities and Fujairah to feed a new Fujairah power and desalination plant
. It will be the longest overland natural gas pipeline in the United Arab Emirates. Five companies were invited to bid by 7 May 2008
for design and construction, and on 22 July 2008
, the US$418 million contract was awarded to Stroytransgaz
. Coated line pipes would be supplied by Salzgitter Mannesmann International. The construction expected to begin during third quarter 2008.
The project is developed and operated by Dolphin Energy, a company established in Abu Dhabi
. It is the operator of all upstream, midstream and downstream phases of the project. Dolphin Energy is 51% owned by Mubadala Development Company
, on behalf of the Government of Abu Dhabi
, and 24.5% each owned by Total S.A.
of France and Occidental Petroleum
of the US.
