Foroozan Oil Field is located 100 kilometers, southeast of Kharg Island. According to Iranian Offshore Oil Company (IOOC) the field has 53 wells and is common with Marjan Field of Saudi Arabia. The field consist of two existing main platforms named FX and FZ, one accommodation platform named FY (currently utilized a jack up rig as temporary LQ at FZ area), one flare platform next to each production platform, two wellhead platforms named F15 and F16 which are linked by a bridge to FX and FZ production platforms respectively and eleven (11) satellite wellhead platforms named F2, F8, F18 (new) (FX area) and F3, F9A, F9, F11, F12, F13, F14, F17 (FZ area). There are 20 numbers of infield pipelines with 6 additional pipelines under installation by COMPANY and one crude as well as one gas export pipelines to Kharg Island. The renovating projects of this field have been tendered and awarded to different Iranian contractors among which, the consortium of PETROPARS-ISOICO (leading by PETROPARS) has been awarded to develop part of the filed. Within the CONSORTIUM, development of the subsurface part shall be carried out by PETROPARS/POSCO (Petropars Oil Services Company) while ISOICO/MSG is responsible for development of surface facilities. The scope of work consists of following topics: A. New Offshore Platforms & Connecting Bridge
• To extract crude oil, one unmanned wellhead platform (F19) is planned to be installed about 7.8 km far from existing FX platform equipped with the minimum production facilities, including topside and a jacket.
• Because of scarcity of space on existing FX, a new entrance block named FX-A, including a jacket and a topside, will be installed in adjacent to FX platform to accommodate new equipment on its deck. FX-A platform shall accommodate all required equipment and facilities including pig launchers/receivers, power generators, LV and MV switchgear rooms, transformers, Control room, piping system, and subsea cable connections. The existing LQ of FX should be transferred and installed on FX-A platform considering all requirements.
• To integrate system and connecting FX-A platform to FX platform, one bridge with intermediate bridge support (if required), accommodating connecting piping, electrical and instrumentation cable systems and walkway between FX-A and FX platform shall be installed between new FX-A platform and existing FX platform.
B. Modifications on Existing Platforms
In addition, to increase the Filed Productivity, Gas Lift Operation is intended. Therefore, some modification including extending Gas Producer Manifold on F16, installation of 5 Transferring Pumps at FX, KOD on FY, Gas Lift Piping Between F15, F18 & F19, Methanol Injection Package on FY (F16), Corrosion Inhibitor on FY (F16), F15, F2 & F8, Generating Electrical Power at FX-A, transferring of LQ and Control Room from FX to FX-A, Oily Water Treatment Package on FX, …, and the required utilities and facilities have been foreseen to be designed, procured and installed.
C. SUBSEA PIPELINES
To transport fluids between new F19 and Existing FX Platform, three 12", 8", 6" subsea pipelines will be installed. Each pipeline will be connected to FX via FX-A and connecting over bridge. The 12" pipeline will transport crude oil from F19 to FX, the 8" pipeline will be used for test and the 6" pipeline will be transport utilized for GL gas from F15 to F19 via FX and FX-A platform.
D. SUBSEA CABLES
• To supply power for FX area platforms and to make communication between FX/FX-A and satellite platforms, subsea cables with 120% of required power capacity including fiber optic for communication will be installed.
• As a future plan, it is planned to supply electrical power consumption of the FX area from FZ-A platform. In line with this requirement, two additional J-Tubes shall be installed on FX-A Jacket.
