Stiction Analysis of Emergency Shutdown Valve Based on Partial Stroke Test

This paper presents an analysis on the stiction of emergency shutdown
valve based on data gathered from partial stroke test software. It is meant to
complement the existing software used to perform partial stroke test. Currently,
most of the partial stroke software does not provide extensive offline analysis.
Therefore, this project is intended to do extensive offline analysis based on
available operational data. The stiction analysis is done based on test rig at
Universiti Teknologi PETRONAS which used ball and butterfly valves. The
analysis comprises Baseline Analysis, Present Analysis, and Comparison of
Baseline Analysis and Present Analysis. First step of the analysis is to determine
the baseline whereby first partial stroke test's data on a specific valve are
gathered. Next step is to do analysis on present data which will be compared with
the baseline analysis in order to detect any unconformity of the valve. Apart from
the analysis, Graphical User Interface is developed for user-friendly interface for
offline analysis of emergency shutdown valve.
