Technip Selects Siemens to Supply Produced Water Filtration and Seawater Injection Systems


Warrendale, Pa., June 8, 2006 -- Technip-France has chosen Siemens to supply a produced water filtration system and a seawater injection system to Total Upstream Nigeria Limited for its Floating Production Storage and Offloading (FPSO) unit of the Akpo field development, offshore Nigeria. This project follows Siemens' successful completion of other projects for Total, including the Dalia FPSO water injection system.

The produced water treatment system, engineered by Siemens Water Technologies, part of Siemens Industrial Solutions & Services (I&S) group, includes the design of a primary vessel (oily water drum), a secondary vessel (hydrocyclones) and a tertiary vessel (induced gas flotation system). This combination of gravity and centrifugal separation, and gas flotation, will reduce oil levels in the influent from 1200-1500 ppm to 30 ppm. The flow rate is designed to handle up to 150,000 BWPD of produced water.

In addition, Siemens Water Technologies, which incorporates USFilter, was awarded an order for a skid-mounted Chloropac® concentric tubular electrode (CTE) seawater electrochlorination package for controlling marine growth. The system will provide 96 kg/hr (211 lbs/hr) of sodium hypochlorite, and the limited installation area required a double-deck skid design.

Siemens Energy and Automation, Alpharetta, Ga., was also successful on this project by obtaining the contract to provide eight fourteen-foot diameter media filters to filter up to 425,000 barrels of seawater per day for reservoir injection.

The Akpo field, operated by Total Upstream Nigeria Limited, is located on the Oil Mining License (OML-130), offshore Nigeria, in water depths ranging from 1,100 to 1,700 meters (3,520 to 5,440 feet). The Akpo FPSO hull will have a storage capacity of two million barrels of oil and will be anchored in 1,325 meters (4,240 feet) of water.
