NFPS Offshore Compression Complexes Project COMP2 SPECIFICATION FOR MACHINERY PROTECTION, CONDITION AND PERFORMANCE MONITORING SYSTEM FOR CP6S & CP7S COMPLEXES

INTRODUCTION

The North Field is the world’s largest natural gas field and accounts for nearly all of the state of Qatar’s gas production. The reservoir pressure in the North Field has been declining due to continuous production since the early 1990s. The principal objective of the NFPS Project is to sustain the plateau from existing QG South Operation (RL Dry Gas, RGE Wet gas) and existing QG North Operation (QG1 & QG2) production areas by implementing an integrated and optimum investment program consisting of subsurface development, pressure drop reduction steps and compression. Refer to the figure below for a schematic of the North Field.

Qatargas Operating Company Limited is leading the development of the North Field Production Sustainability (NFPS) Project.

1.1 Project Objective

The objective of this Project includes:

• Sustain the Qatargas North Field Production Plateau by installing new Compression Complex facilities CP6S & CP7S in QG south with integration to the existing facilities under Investment #3 program.

• Facility development shall be safe, high quality, reliable, maintainable, accessible, operable,

and efficient throughout their required life.

• Achieve standards of global excellence in Safety, Health, Environment, Security and Quality

performance.

1.2 Project Scope

The Project Scope includes detailed engineering, procurement, construction, transportation & installation, hook-up and commissioning, tie-in to EXISTING PROPERTY and provide support for start- up activities of the following facilities and provisions for future development. The WORK shall be following the specified regulations, codes, specifications and standards, achieves the specified performance, and is safe and fit‐for‐purpose in all respects.

Offshore

CP6S and CP7S Compression Complexes that are part of QG-S RGE facilities as follows:

• CP6S Compression Complex

• Compression Platform CP6S, Living Quarters LQ6S, Flare FL6S

• Bridges BR6S-2, BR6S-3, BR6S-4, BR6S-5

• Bridge linked Tie-in to RP6S

Production from existing wellheads (WHP6S & WHP10S) and new wellhead (WHP14S) are routed via riser platform RP6S to compression platform CP6S to boost pressure and export to onshore via two export lines through the existing WHP6S pipeline and a new 38” carbon steel looping trunkline from RP6S (installed by EPCOL). CP6S is bridge-linked to RP6S.

• CP7S Compression Complex

• Compression Platform CP7S, Living Quarters LQ7S, Flare FL7S

• Bridges BR7S-2, BR7S-3, BR7S-4, BR7S-5

NFPS Offshore Compression Complexes Project COMP2 SPECIFICATION FOR MACHINERY PROTECTION, CONDITION AND PERFORMANCE MONITORING SYSTEM FOR CP6S & CP7S COMPLEXES

• Bridge linked Tie-in to RP7S

CP7S shall receive production from existing wellheads (WHP5S & WHP7S) and new wellhead (WHP13S). There is only one export line for CP7S through the existing export pipeline from WHP7S. CP7S is bridge-linked to RP7S.

RGA Complex Destressing

Migration of the Electrical power source, Telecoms, Instrumentation and Control systems from WHPs and RPs hosted by RGA to the respective Compression Complexes listed below:

• WHP6S, WHP10S, WHP14S, RP6S and RP10S to CP6S Compression Complex

• WHP5S, WHP7S, WHP13S and RP7S to CP7S Compression Complex

Destressing of Telecoms, Instrumentation and Control system in RGA Complex Control Room, which would include decommissioning and removal of telecom system devices and equipment that would no longer be required post migration and destressing activity.

Onshore

An Onshore Collaborative Center (OCC) will be built under EPC-9, which will enable onshore based engineering teams to conduct full engineering surveillance of all the offshore facilities. The OCC Building will be located in Ras Laffan Industrial City (RLIC) within the Qatar Gas South Plot. MICC & Telecommunication, ELICS related scope will be performed in the OCC building.

CP area – MMS/CMPS equipment (other than GTC/GTG) shall be powered by IMICC PDB.
CP area – MMS/CMPS equipment for GTC/GTG shall be powered by GTC/GTG package PDB
LQ area – All MMS/CMPS equipment (including GTC, cabinets/panels inside CCR and CCR

Rack Rooms) shall be powered by IMICC PDB.

All the instruments shall be generally 24VDC loop powered from package UCPs, as applicable. However, for GTC/GTG packaged field instrument and equipment in field if need 230 VAC UPS external power supply, it shall be powered from the PDB by the GTC/GTG Vendor.

Each cabinet, that requires power, shall be equipped with dual feeders for UPS supply. UPS supplies shall be fed from independent buses. All the components inside cabinets (i.e. control system components (controllers, I/O modules etc), panels fans including all non-essential utility power supplies such as panel lighting and utility sockets) shall be powered by the UPS supply. Each cabinet shall be provided with fans to ensure that HVAC failure does not expose electronics to more than 49°C.

Automatic transfer switch or differential switch between the dual supplies shall only be used for equipment where redundant power supply may not be available (e.g. power supply to workstations and HMI).
