Saudi Aramco: Company General Use

1 Scope

This specification covers the Saudi Aramco requirements of PST for power operated

Emergency Isolation Valve (ZV). The ZV valve assembly provides local control and

testing functionality for valve actuators. Functional requirements are clarified including

the “partial stroke” feature provided for on-line testing of ZV's. Partial Stroke Testing

(PST) system is not part of the Safety Instrumented System (SIS).

Alternative designs not covered by this specification shall only be used when pre-

approved by the Manager, Process and Control Systems Department.

2 Conflicts and Deviations

Any conflicts between this document and other applicable Mandatory Saudi Aramco

Engineering Requirements (MSAERs) shall be addressed to the EK&RD Coordinator.

Any deviation from the requirements herein shall follow internal company procedure

SAEP-302.

3 References

4 Terminology

4.1 Acronyms

DCS: Distributed Control System

LCP: Local Control Panel

SIS (or ESD): Safety Instrumented System

PST: Partial Stroke Testing

UPS: Uninterruptable Power Supply

4.2 Definitions

Distributed Control System (DCS): A process control system that is composed

of distinct modules. These modules may be physically and functionally

distributed over the plant area. The distributed control system contains all the

modules and associated software required to accomplish the regulatory control

and monitoring of a process plant, excluding field instruments, remote terminal

units, auxiliary control systems, and plant information systems.

Emergency Shutdown System (ESD): A system composed of sensors, logic

solvers, and final control elements for the purpose of taking the process, or

specific equipment in the process to a safe-state when predetermined conditions

are violated or when an operator initiates a shutdown. The system is designed to

isolate, de-energize, shutdown or de-pressure equipment in a process unit.

Another term commonly used throughout the hydrocarbon and petrochemical

industry is a Safety Instrumented System (SIS).

Partial Stroke Testing (PST): It is a way to verify emergency isolation valve

performance when functional testing is required while the emergency isolation

valve is on-line. Partial Stroke testing is not intended to take the place of full-

stroke emergency isolation valve functional tests. Rather, “partial stroke”

testing should be performed to meet the required functional test interval
