Siemens has secured an 18-year contract to provide services to Abu Dhabi-based gas company Dolphin Energy's Dolphin Gas Project in Qatar.
Under the terms of contract, Siemens will provide service and maintenance for nine aero-derivative gas turbines from former Rolls-Royce Energy as well as the nine Dresser-Rand compressors.
The Dolphin Gas Project consists of the production, processing and transportation of natural gas from North Field in Qatar.
Mubadala Development in Abu Dhabi owns 51% in Dolphin Energy, while Total and Occidental own the remaining shares equally.
"This order impressively underscores that we are on the right path with our acquisitions of Rolls-Royce Energy and Dresser-Rand."
Siemens member of the managing board Lisa Davis said: "This order impressively underscores that we are on the right path with our acquisitions of Rolls-Royce Energy and Dresser-Rand."
"Together, we not only have the biggest installed fleet in the industry worldwide, we are now also able to offer our customers from oil and gas and from industry a unique range of services - which opens up great opportunities."
The Dolphin Gas Project is the natural gas project of the Qatar, UAE, and Oman and 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.
It will also have a gas processing and compression plant at Ras Laffan in Qatar.
Dolphin Energy CEO Adel Ahmed Albuainain said: "This long-term service agreement places our company on an even stronger footing because it supports our efforts to ensure the sustainability, reliability and availability of natural gas exports to the UAE and Oman.
"It also builds on the existing strong relationship we developed with Rolls-Royce, which has now transferred to Siemens and continues to provide Dolphin Energy with direct access to the original equipment manufacturer, thereby providing us the best service available in the market."
