Project Description
Foroozan Oil Field Development – Offshore
Client
Mobin Sazeh Gostar Khalije Fars (ISOICO/MSG)
Owner
Iranian Offshore Oil Company (IOOC)
Location
Persian Gulf, Iran
The Foroozan Oil Field is located 100 kilometers southeast of Kharg Island. According to the Iranian Offshore Oil Company (IOOC), the field comprises 53 wells and shares boundaries with Saudi Arabia’s Marjan Field. Key components of the field include:
- Two main platforms: FX and FZ
- One accommodation platform: FY (currently used as a jack-up rig for temporary living quarters at the FZ area)
- One flare platform adjacent to each production platform
- Two wellhead platforms: F15 and F16, connected by a bridge to the FX and FZ production platforms, respectively
- Eleven satellite wellhead platforms: F2, F8, F18 (new) (FX area) and F3, F9A, F9, F11, F12, F13, F14, F17 (FZ area)
- 20 infield pipelines, with 6 additional pipelines under installation
- One crude oil and one gas export pipeline to Kharg Island
Renovation projects for this field have been tendered and awarded to various Iranian contractors. The consortium of PETROPARS-ISOICO (led by PETROPARS) has been awarded the development of part of the field. PETROPARS/POSCO (Petropars Oil Services Company) will develop the subsurface part, while ISOICO/MSG is responsible for the surface facilities.
Scope of Work:
A. New Offshore Platforms & Connecting Bridge:
Unmanned Wellhead Platform (F19):
- To be installed about 7.8 km from the existing FX platform.
- Equipped with minimal production facilities, including topside and a jacket.
New Entrance Block (FX-A):
- To be installed adjacent to the FX platform due to limited space on the existing platform.
- FX-A will house all required equipment and facilities, including pig launchers/receivers, power generators, LV and MV switchgear rooms, transformers, control room, piping systems, and subsea cable connections.
- The existing living quarters (LQ) of FX will be relocated and installed on FX-A, considering all requirements.
Connecting Bridge:
- A bridge with intermediate support (if required) will be installed between the new FX-A platform and the existing FX platform.
- It will accommodate connecting piping, electrical and instrumentation cable systems, and walkways.
B. Modifications on Existing Platforms:
- Gas Lift Operations and Productivity Enhancements:
- Extending the Gas Producer Manifold on F16
- Installing 5 Transferring Pumps at FX
- Installing KOD on FY
- Gas Lift Piping between F15, F18, and F19
- Methanol Injection Package on FY (F16)
- Corrosion Inhibitor on FY (F16), F15, F2, and F8
- Generating Electrical Power at FX-A
- Relocating the LQ and Control Room from FX to FX-A
- Installing an Oily Water Treatment Package on FX
- Designing, procuring, and installing necessary utilities and facilities
C. Subsea Pipelines:
- Three Subsea Pipelines (12″, 8″, and 6″):
- To transport fluids between the new F19 and the existing FX platform.
- Each pipeline will be connected to FX via FX-A and the connecting bridge.
- The 12″ pipeline will transport crude oil from F19 to FX.
- The 8″ pipeline will be used for testing.
- The 6″ pipeline will transport gas lift (GL) gas from F15 to F19 via FX and FX-A platforms.
D. Subsea Cables:
- Power Supply and Communication:
- Subsea cables with 120% of the required power capacity, including fiber optics for communication, will be installed to supply power to FX area platforms and enable communication between FX/FX-A and satellite platforms.
- Future planning includes supplying electrical power for the FX area from the FZ-A platform, with two additional J-Tubes to be installed on the FX-A Jacket.
Contract Time Period: January 27, 2021, to July 30, 2023.
