SABP-Z-002 Functional Specifications for Process Control Systems
Introduction 1.1
Purpose The purpose of this document is to provide recommended guidelines for defining Functional Specifications and Scope of Work for a Process Control System (PCS) project. It is recommended that Project Teams use the appendices of this document as a starting point in the definition of the Process Control Systems required for their project. Items highlighted in “Red” color should be filled in with information specific to the project.
1.2
Scope The scope of this document is the definition of Functional Requirements and Scope of Work for Process Control Systems referenced in the attached appendices.
1.3
Intended Users This document is intended to be used by Saudi Aramco Project Management Teams (SAPMT) whom are working on projects which require Process Control Systems.
1.4

General Project specifications for Process Control Systems (PCS) should be dev eloped in a manor which separates the ‘Functional’ requirements from the a ctual Scope of Work for the project. For a majority of projects, the functional requirements for the process control system will not vary significantly. It is mainly quantities which will differ. By separating general functional / technical requirements from project specific / Scope of Work requirements; functional requirements which are generic and can be reused from project-to-project can be developed. Process & Control Systems Department have developed the generic functional requirements documents. These are contained in the attached appendices. The main responsibility of the project team is to develop the actual Scope of Work for the project. The appendices of this document should be used as a ‘Go-By’ for developing the project specific scope of work. This document along with the relevant generic functional specifications document and Saudi Aramco standards shall serve as the basis for procurement of the PCS.
