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.
