Description

• This was the first deepwater project for Shell in Nigeria in a water depth of 3,000 ft located 120 km off coast of the Niger Delta using a FPSO
• The FPSO, measures over 300 metres long, 75 metres wide and 33 metres tall. The Bonga FPSO can extract and process up to 225,000 barrels of oil a day and store up to 2 million barrels of oil. It also has a gas export facility of 150 million standard cubic feet per day
• Bonga North-West is located in approximately 900 to 1,200 meters of water, and has been developed with 12 subsea wells tied back into the Bonga main infrastructure.
• Bonga Phase 3 is an expansion of the Bonga Main development, with peak production expected to be some 50,000 barrels of oil equivalent. This is transported through existing pipelines to the Bonga FPSO
• Bonga North will be a subsea tie-back to the Bonga FPSO. The Bonga North project involves drilling, completing, and starting up 16 wells (8 production and 8 water injection wells), modifications to the existing Bonga Main FPSO and the installation of new subsea hardware tied back to the FPSO.

Contractors

• AMEC: FPSO Engineering Procurement Construction contract
• Samsung Heavy Industries(SHI): FPSO hull construction
• Saipem: Engineering, procurement, fabrication, installation and pre-commissioning services for 13 kilometres of 10”/12” production pipe-in-pipe flowlines, 4 kilometres of 12” water injection flowlines as well as related production facilities for Bonga North-West
• Subsea 7: Eight production flowlines, 10-inch, 26km total length, with six Steel Catenary Risers (SCRs) each 2km in length, two production flowlines, 12-inch, 12km total length, with two SCRs each 2km in length. In addition, a total of 24km of 12-inch water injection flowlines with 2km long SCRs transport treated seawater from the FPSO to several subsea injection wells.
