Dolphin Qatar-UAE Natural Gas Pipeline, also known as Ras Laffan-UAE pipeline, is an operating natural gas pipeline in Qatar, the United Arab Emirates, and Oman.[1]


The Pipeline begins in Qatar and runs offshore through the Persian Gulf to Taweelah in the United Arab Emirates. From there, the pipeline intersects with a number of small pipelines which move throughout U.A.E. and branch out into Oman.[2]

Project Details

  • Operator: Dolphin Energy[3]
  • Parent Company: Mubadala Development Company (51%), Total (24.5%), Occidental Petroleum (24.5%)
  • Capacity: 3,200 million cubic feet per day
  • Diameter: 48 inches[4]
  • Length: 370 kilometers/ 230 miles
  • Status: Operating
  • Cost: USD 3.5 billion[5]
  • Start year: 2006


Dolphin Energy, the constructor and operator of the project pipeline, is jointly owned by Mubadala Development Company (51%), Total of France (24.5%) and Occidental Petroleum of the United States (24.5%). The first phase involved the development of two platforms in Qatar’s North field, two multi-phase offshore sealines to the processing facilities and the gas treatment and compression plants at Ras Laffan. The second phase involved the construction of a 48in diameter, 260 mile (364km) subsea pipeline that carries gas to the UAE (cost $3.5bn). The second phase was completed in August 2006. The pipeline has a capacity of 2 billion cubic feet per day and potentially can carry upwards to 3.2 billion cubic feet per day.[5]

The Dolphin pipeline was the first pipeline laid as part of the Dolphin Natural Gas Project between Qatar and U.A.E. The second pipeline laid was the Al Ain - Fujairah pipeline, followed by the last the leg of the project, the Taweelah-Fujairah pipeline.[6]

The Dolphin Gas Project is one of the largest trans-border energy projects ever undertaken in the Middle East. The project brings natural gas from Qatar via pipeline to the United Arab Emirates (UAE). The $7bn project has brought together three Gulf Cooperation Council (GCC) nations – UAE, Qatar and Oman – into an integrated regional energy network for the first time.[7]

In 2015, Dolphin Energy raised $863 million in debt from BNP Paribas, MUFG, and SMBC to expand the pipeline’s capacity by adding three new compressors to the six already in operation.
