Taweelah Receiving Facilities
Dolphin Energy's gas produced in Ras Laffan, Qatar - arrives at the heart of the company’s UAE Operations; The Taweelah Receiving Facilities in Abu Dhabi, UAE. The Facilities consist of three parallel gas receiving trains, metering facilities, control buildings and warehousing. The Facilities are joined to various interconnecting pipelines that link customers’ facilities.
The engineering, procurement and construction (EPC) contract for Taweelah was awarded to Technip/Al Jaber in 2004 and construction was completed early in 2007. The Facilities were subsequently tested and commissioned, thanks to temporary supplies of early gas from Qatar Petroleum in March, before receiving regular supplies of Dolphin Energy's own gas from Qatar from July 2007.
Consumer Receipt Stations
Natural gas is distributed throughout the UAE Gas Network (UAEGN) from the Taweelah Receiving Facilities (TRF) to customers in the Emirates and Oman. This is done via receipt stations across the network, which is located at Taweelah and Umm Al Nar in Abu Dhabi, at Jebel Ali in Dubai, Fujairah and at the UAE-Oman border.
Al Ain Control Station Valve Station
Before its unmanning in the middle of 2009, the Al Ain Control Station used to be the Control Station of Gas operations for the Al Ain to Fujairah Pipeline (AFP). Thirty two Block Valve Stations were installed to allow segments of these pipelines to be isolated in case of emergency or for maintenance purposes.
Eastern Gas Distribution System
Once gas arrives at Taweelah, the majority is supplied to other parts of the UAE using Dolphin Energy's Eastern Gas Distribution System (EGDS). The EGDS is also used to transport natural gas to Oman, using a connection with a pipeline on the Omani border. This connection was put in place in October 2008 thus completing the tri-nations gas grid.
The EGDS was upgraded by Dolphin Energy between 2006 and 2007 as part of a long-term lease agreement with Abu Dhabi National Oil Company (ADNOC). This involved the refurbishment and recoating of existing pipelines and the addition of fiber optic cables for communications purposes.
Dolphin Energy EGDS pipelines vary between 18 and 48 inches in diameter. Principal pipeline distances involved are:
Taweelah to Maqta—52-kilometers
Maqta to Jebel Ali—112-kilometers
Maqta to Al Ain—148-kilometers
Al Ain - Fujairah Pipeline
Dolphin Energy entered the business of gas supply in January 2004, when the company commissioned the natural gas pipeline that connects Al Ain with the UAE east coast emirate of Fujairah.
This 24-inch, 182-kilometer pipeline provides fuel for ADWEC’s major 656 MW power plant and 100 million gallons-per-day desalination plant at Qidfa–benefiting hundreds of farmers and scores of inland rural communities.
Initially all the gas being delivered by Dolphin Energy came from Oman, delivered via a tie-in on the UAE-Oman border near Al Ain. Up to 135 million standard cubic feet of gas per day (scf/day) was being supplied by the Oman Gas Company. As a result, refined gas started flowing by land from one GCC nation to another for the very first time.
Once Dolphin Energy began receiving gas from Qatar in July 2007, the company started to supply Fujairah with gas directly, through the new and refurbished pipelines connecting Taweelah with Al Ain.
Taweelah - Fujairah Pipeline
In 2007 Dolphin Energy embarked on the conceptual design of a new natural gas pipeline to link its receiving facilities at Taweelah with Fujairah on the UAE’s east coast.
A detailed Environmental and Social Impact Assessment (ESIA) was undertaken in the same year to identify all measures necessary to minimize the pipeline’s impact on the environment and local communities along its path.
A contract for the manufacture and delivery of coated pipeline was awarded to Salzgitter Mannesman International of Germany December 2007. A Design and Build contract was awarded to PJSC Stroytransgaz in July 2008.
After three years, planning and construction the Taweeleh - Fujairah Pipeline (TFP) was completed in 2010. This substantial 48 inch pipeline crosses 244-kilometers of the heart of the country; through Abu Dhabi, Dubai and Sharjah, then over the mountains of Ras Al Khaimah and Fujairah itself.
With a design capacity of 1.6 billion scf/day, TFP supplies the immediate and future gas requirements of Dolphin Energy's largest customer ADWEC at the existing Fujairah 1 and Fujairah 2 power stations and desalination plants. The Fujairah 2 plant has been built next to the existing Fujairah 1 plant at Qidfa, on the Arabian Sea north of Fujairah city, which already receives gas from Dolphin Energy via the company’s Al Ain to Fujairah pipeline.
Other pipelines used in the UAE Gas Network include the 48-inch line from the Taweelah Receiving Facilities (TRF) to the tie-in facility at Taweelah and the 36-inch line from TRF to ADWEC’s Taweelah Power Station.
