INTRODUCTION
The North Field is the world’s largest natural gas field and accounts for nearly all the State of Qatar’s gas production. The principal objective of the NFPS projects is to sustain plateau from existing QatarEnergy LNG Operation – S1, S2, S3, N1 and N2, production areas by implementing an integrated and optimum investment program consisting of subsurface development, pressure drop reduction steps and compression.
NFPS projects comprise 3 main investment programs:
Investment #1: Drilling and Associated Facilities [WHP12S/ WHP13S/ WHP14S/ WHP12N/ WHP13N] Investment #2: Trunk line Looping and Intra-field pipeline looping [32” PL1LN, 32” PL1LS, 38”PL610LS] Investment #3: Compression Complexes and associated facilities [Phase 1 CP6S & CP7S; Phase 2: CP8S & CP4N; Phase 3: CP4S & CP6N Phase 4: CP1S & CP1N]

PURPOSE
The purpose of this document is to define the minimum requirements for the design, materials, fabrication, inspection & testing and documentation for Electrical equipment on Packaged units supplied by equipment VENDORS as part of packaged units for NFPS Compression project.
This specification shall be read in conjunction with the electrical data sheets and the equipment supplied shall be capable of meeting all the requirements stated therein. This specification is complementary to the Data Sheets for the individual items of equipment. Compliance by the VENDOR, with the provisions of this specification does not relieve him of his responsibility to furnish the equipment and accessories of a proper design to meet the specified service conditions, Local Codes and Agreements, Statutory Legislation and Health and Safety requirements.
This Specification and referred specifications and standards shall be applicable, in general for offshore compression facilities.
5
SCOPE
The specification shall cover the complete supply of the equipment and auxiliary systems design, engineering, materials, fabrication, assembly, coordination, weight control, inspection, testing, certification, surface preparation and painting, documentation, export packing, corrosion protection and delivery in full compliance with the requirements of this specification.
This specification shall be read in conjunction with the appropriate electrical, mechanical, equipment and instrument specifications for the main equipment.
This Specification does not dictate the detailed design of the equipment or assembly of components. It is intended that those responsibilities be retained fully by the VENDOR so that all equipment warranties remain unmitigated. This Specification includes tagging and packing for the preparation for overseas shipment of all equipment furnished. The specification shall be applicable as part of the Request for Quotation/ Material Requisition/ Technical Requisition Package and form part of the Purchase Order.
