PROJECT DESCRIPTION General

ENI has been awarded the Zubair project for the development of an oil field (ZUBAIR FIELD) in joint venture with Occidental, Korea Gas and Missan Oil COMPANY (as state partner), with Eni as operator. The Zubair Field is located in the southern area of Iraq, 20 km from Basra city. The structure of the Zubair Field is a relatively gentle anticline oriented NNW SE, approximately 60 km long and 10-15 km wide. The Zubair project is a “brown field project” in which two main phases can be defined:

1.2

•

Rehabilitation Phase (or RP) in which includes the revamping of existing facilities to maximise production capacity of the existing treatment plants in order to achieve an oil production rate of 700 kBOPD at Q3 2013, after rehabilitation of wells, gathering network and overall facilities, plus installation of new facilities as required. These activities should be concluded within 36 month starting from the CED.

•

Enhanced Re-Development Phase (or EP). During this phase the installation of new permanent production facilities to achieve the plateau rate of 1200 kBOPD of oil production has been foreseen. The oil will be produced from reservoir with natural flowing and artificial lift systems requiring also water injection to support reservoir pressure and maintain it above saturation pressure. This second phase should be finished within 6 years from the CED.

Objective The primary objective of this document is to define the minimum requirements for the design, manufacturing, delivery, installation and testing of the FIBER OPTIC CABLE for the following SITES: Zubair Degassing Station; • Zubair Mishrif Degassing Station; • Hammar Degassing Station; • Hammar Mishrif Degassing Station; • Rafidiya Degassing Station; • Safwan flow station; • Power Generation Plant; • Gas Treatment Plant; • New Tankfarm; • Sea Water Intake; • River Water Intake (To Be Defined); • Field Office District; • Radio Shelter; • Fiscal Metering Site (If located outside DGS); • New Remote Wells and Manifolds; •

The FIBER OPTIC CABLE shall be the physical support to the WAN and LAN Systems that provides communications for voice and data services within Zubair Field SITES and FACILITIES. The FIBER OPTIC CABLE shall be installed by CONTRACTOR within the Degassing Station and Main SITES and remote FACILITIES areas, along new Gas and Water pipelines and between Degassing Station and new wells and manifolds SITES along new trunklines and flowlines. All CONTRACTOR ITEMS necessary for the safe and satisfactory operation of the system shall be included notwithstanding exclusions or omissions from the specification.

OVERALL REQUIREMENTS General This specification details the design and characteristics for the FIBER OPTICAL CABLE used for Zubair Field. The FIBER OPTICAL CABLE used for Zubair Field shall be used for data and voice connection between within various site. RTUs, ICSS, Telephones, WAN over FOC, LAN, security, video, trunkline monitoring and integrity signals shall be exchanged between within sites through backbone of fiber optical cables. The FIBER OPTICAL CABLE should be the preferred engineering solution for data exchange of above mentioned services. The function of the Fiber Optical System is to provide a physical layer of connectivity for the distribution of Telecommunications and Automation services along the pipelines, between within the Zubair Field DGSs, main SITES and FACILITIES for both Process and Non-Process areas. The FOC shall also facilitate telecom fiber optic connectivity to the Wells and Manifolds area. Along new oil trunklines, FIBER OPTICAL CABLE shall also be used for pipeline monitoring systems, for that purpose, three cables shall be laid along trunklines: n° 1 (one) cable shall be used for LAN/WAN over FOC • n° 2 (two) cables shall be used for pipeline monitoring system (FOPIMS) • This section gives the minimum requirements, reference standards, test and supply conditions for the supply of t he fiber optical cables for Zubair Field. The supply shall include but not limited to: • •

Fiber Optical Cables FOC joint splicing enclosures

TECHNICAL REQUIREMENTS General Three Two types of Fiber Optical Cables (here called FOC Type 1, FOC type 2 and FOC Type 3) shall be supplied by SUBCONTRACTOR suitable for direct buried installation together with Oil trunklines/flowlines and Gas pipelines (FOC Type 1), Water Pipelines (FOC Type 2) and Over Head Lines (FOC Type 3) . Type 1 FOC shall be suitable to be installed close to Oil trunklines/Flowlines and Gas pipelines while Type 2 FOC shall be suitable to be installed close to water Flowlines/pipelines. Type 3 FOC shall be suitable for Optical Ground Wires installation over power supply lines. Type 1 FOC shall also be suitable for installation within DGS and Main SITES and remote FACILITIES area for data/voice/video/CCTV signals distribution. Type 2 FOC shall be suitable for installation within DGS and Main SITES and remote FACILITIES area for CCTV Cameras signals distribution. Type 1, and Type 2 and Type 3 FOC quantities shall be defined by CONTRACTOR during engineering design considering at least 10% of spare quantities plus quantities above considered plus at least 10m for each manhole during installation. Type 1 and Type 2 FOC shall be included in the FOC SUBCONTRACTOR scope of supply. Type 3 FOC shall be included in the SUBCONTRACTOR supply of the Over Head Lines package.

5.2

Fiber Optical Cable Type 1 The Fibre Optical Cables Type 1 shall be of Corrugated Steel Tape Armoured, Loose Tubes Single Mode type (SM), suitable for direct burial installation. The number of cable cores shall be 24 The tubes shall be filled with filling compound and stranded, together with fibres, around a central dielectric strength member (FRP) to form a compact and circular core. Loose tube with 6 or 8 fibres shall be acceptable. Around the loose tube and fillers, polyester tape shall be applied. Over the cable st core a 1 intermediate black PVC sheath shall be applied. st

Over the 1 intermediate sheath, to prevent cable from petrochemical and chemical compounds an inner jacket of Aluminium tape (coated on both side with a copolymer), HDPE and Nylon (PA) shall be applied. Cable armouring shall consist of a corrugated steel tube (copolymer coated on both side) located between the Nylon (PA) inner jacket and FR PVC outer jacket. The outer jacket along with the corrugated steel armouring shall protect the fibres from rodents and termites. Each single mode Optical fibre shall be designed to provide good performance at both 1310nm and/or 1550nm. The geometric and transmission characteristics shall fully comply with ITU-T-G-652D (06/2005).

Should it be impossible, for any valid reason, to complete the backfilling operations after lowering-in, CONTRACTOR shall carry out partial backfilling to protect the cables into the trench. Backfilling of the trench shall be completed within 24 hours from partial backfilling. The material used for backfilling will be trench excavated material, free from This document is property of Eni S.p.A. Exploration & Production Division.
