Executive Summary


Aramco awarded Fluor a project management contract for a new offshore gas gathering project. The complex work scope recovered gas flared off in the Arabian Gulf offshore fields. The gas was collected and treated from three separate offshore fields in Safaniya, Marjan and Zuluf, then transported by pipeline to shore at Safaniya and Tanajib.

From there, the gas was transported along the coast to processing facilities previously constructed by Fluor at Berri, Shedgum and Ju'aymah. In total, more than 150 miles of various diameter pipelines, primarily offshore, was installed.

Client's Challenge


The Safaniya facilities were designed to gather 170 million standard cubic feet per day (MMSCFD) of field gas from the Safaniya gas-oil separation plant (GOSP)-2/3/4 high pressure production trap gases, to provide offshore gas compression and ancillary equipment to serve Safaniya GOSP-2/3/4 and to transport the gases to Safaniya GOSP-1 onshore for further handling. Gas would be gathered and compressed at two separate compressor platforms accommodating a total of 50,000 HP turbine driven units.

At Marjan, facilities were designed to gather 900 MMSCFD of field gas from Marjan GOSP-1/2/3 offshore gas pressure production trap gases, to provide offshore gas compression and ancillary equipment to serve Marjan GOSP-2 and to transport the gases to Tanajib for further handling.

At Zuluf, the facilities were designed to gather 550 MMSCFD of field gas from the Zuluf GOSP-1/GOSP-2 high pressure production trap and Zuluf GOSP-2/GOSP-4 low pressure production traps, to provide offshore gas conditioning facilities and ancillary equipment at Zuluf GOSP-2 and to transport the gases to Safaniya for further handling.

Fluor's Solution


For the Marjan and Safaniya projects, our work involved a project series that included definitive scoping studies, project proposal preparation, expenditure request estimate preparation, lump sum, turnkey bid package preparation and material procurement assistance.

The Zuluf and Marjan projects included project management services for the work to be performed by lump sum, turnkey design/fabrication/construction contractors.

Conclusion


Aramco invested capital to recover the gas flared at three offshore platforms by constructing a new gas gathering network. The pipelines collected, treated and transported gas to their onshore processing plants. The recovered gas generated additional revenue while significantly benefiting the environment.
