This procedure specifies the requirements to conduct Factory Acceptance Test (FAT) and Site Acceptance Test (SAT) for the Medium Gas Metering Systems with Ultrasonic Meters as specified by 34-SAMSS-153 and 34-SAMSS-114. Conducting these tests is mandatory as stated in SAEP-21 and SAEP-50.
The purpose of the FAT and SAT is to demonstrate, to the fullest extent possible at the vendor’s facilities and site location, that the subject Medium Gas Metering System meets all requirements of the Job Specification, particularly the Functional Specification Document before being shipped to the site and before commissioning. The test shall include the functionality of the Metering Skid (software, hardware and special application packages).

4 Definitions and Acronyms
Approve: Review and formal acceptance characterized by the signature of a final authorizing individual or organization.
Buyer: The Company (Saudi Aramco, Aramco Overseas Co., or Aramco Services Co.) actually placing the order for the material. The buyer can be a third party metering system customer.
Buyer’s Representative: The person acting on behalf of the Buyer, who may be from the Engineering, Inspection, Purchasing, or User organization.
Company: Refers to a Saudi Arabian Oil Company (Saudi Aramco) and its affiliates.
Construction Contractor: An entity that is responsible for construction of a facility based on the approved project documentation provided by Saudi Aramco.
Custody Transfer Measurement: A specialized form of measurement that provides quantity and quality information used for the physical and fiscal documentation of a change in ownership and/or responsibility of hydrocarbon commodities. This includes measurement of hydrocarbon liquid movements (deliveries or receipts) between Saudi Aramco and its customers, suppliers, joint ventures and transport contractors including VELA ships.
Factory Acceptance Test (FAT): A series of tests conducted at the vendor’s plant to demonstrate compliance of the System with the job specification requirements, to the maximum extent possible in the Contractor’s factory environment.
Functional Specification Document (FSD): Provides the technical requirements for the System.
Job Specification: The scope of the work to be performed pursuant to a contract; it describes or references the applicable drawings, standards, specifications, as well as the administrative, procedural, and technical requirements that the Contractor shall satisfy or adhere to in accomplishing the work.
Medium Gas Metering System: A metering system designed to handle gas flow rates between 20 MMSCFD and 200 MMSCFD.
Non-Material Requirements (NMRs): The complete set of documentation required in the electronic form from the Vendor and/or the Contractor during the design and development phase of the project. There are three categories of NMRs:
601 NMRs: Preliminary drawings for review and approval.
602 NMRs: Certified drawings, literature, photographs, and parts data/requirements.
603 NMRs: Operations, maintenance manuals, installation instructions, test certificates, etc.
Pre-FAT: A comprehensive test, completed by the vendor prior to FAT, which ensures that the System can be tested according to FAT procedures without unanticipated delays.
Proponent: The Saudi Aramco organization responsible for signing the Saudi Aramco Form 7213-ENG, Mechanical Completion Certificate. In the context of this document, the Proponent is the Saudi Aramco organization responsible for operating and maintaining the metering facility.
Project Management Team (PMT): The team of Company individuals who are assigned the responsibility of managing the project.
Site Acceptance Test (SAT): A series of tests conducted at the site location on the installed System that demonstrates compliance with all requirements, except availability.
System: is the metering skid system that is procured under the Contract.
Vendor: The party that supplies or sells integrated metering systems, metering equipment, or components sometimes called Integrator.

SAT Site Acceptance Test
The FAT (SAT) Report shall contain the following sections, as a minimum:
a) Identify System and Vendor
b) Include certification statement
c) FAT (SAT) location, start date, completion date
d) Name of Contractor/Vendor representative and signature
e) List of Company representatives and signatures
