The project team headquartered in Fluor's U.K. office provided engineering, procurement, and construction management services to TCO for both the SGI and SGP Projects. The scale of the undertaking called for engineering to be performed 24 hours a day at project offices located in different time zones around the world. Construction also presented challenges, with a multinational workforce from 61 countries performing construction under hostile climatic conditions. Extreme weather conditions and temperatures range from +40 Celsius in summer to below -40 Celsius in winter.
SGI – The SGI project was divided into two stages:
- Stage 1 was performed to inject sweet gas from the processing facilities into the reservoir to prove the operation of the compressor and validate the predicted response of the reservoir.
- Stage 2 expanded the installation, permitting injection of high pressure sour gas (17% H2S) from SGP and providing the opportunity to process an additional 3 million tonnes of oil within the oil/gas separation area of SGP.
Key to the success of the project was pioneering a compressor and associated piping systems capable of delivering sour gas into the reservoir at 10,000 PSI in a way that is both safe and dependable.
SGP – The SGP project included a one-year front-end engineering and design [FEED] followed by detailed design and construction with the SGP greenfield facilities, including new production wells and associated gathering system together with crude stabilisation, crude desalting, sour gas dehydration, gas processing, sulfur recovery, crude oil export systems, LPG processing, storage, and loading, as well as offsites and utilities.
The Fluor JV also provided engineering, procurement and construction management services for a power plant at the TCO project site. The scope of facilities included two Frame 9E GE gas turbine generators, each with a nominal rating of 123 MWe, including all associated electrical, control and instrumentation equipment, and two supplementary-fired Heat Recovery Steam Generators (HRSGs). Each HRSG is capable of generating a maximum of 450 tons per hour of steam at 370 °C and a pressure of 72 bar, using gas turbine exhaust gas and full supplementary firing.
In addition to the major power plant equipment, the Fluor JV was responsible for all associated piping and support racking necessary, electrical and control equipment, and BOP equipment within the Power Island battery limits.
