Abstract

Partial Stroke Valve Testing (PST) which is related to the Emergency Valve
Shutdown System is a method whereby the performance of a portion of a valve is
tested at more frequent interval (accelerated proof test). PST can be a good
complement to Full Stroke Testing (FST). The objective of this project is to develop
a control for a PST that is based on a system called Programmable Logic Controller
(PLC) as the main controller to do Full Stroke Testing and for the Partial Stroke
Testing: it was conducted using software provide by the vendors. The problems that
have been identified during the system familiarization and training session are
needed to be solved in order to meet the project's objective. One of the problems is
that first owing to the fact that the PST will be done using three different software
from three different vendors, the valves are having problems to communicate with
each other due to the connection architecture (point to point connection). Therefore a
multiplexer is needed to be installed in between the connection. Scope of the study
involved the detail explanations of the Metso' s valves specifications. Furthermore,
the device called V alvGuard that is attached to the valves and also the Field Care
Software (Metso' Valve Software) is discussed. The specification of the PLC device
and the example of the ladder diagram developed and used in this project is
presented. The software provided by Y okogawa called WideField2 is explained.
