A Study of Partial Stroke Test for Emergency Shutdown System (ESD) Using Masoneilan Valve

This report presents the progress and the future development of the work in Partial Stroke Testing.
Partial Stroke Test is a good complement to Full Stroke Testing (FST). During the FST operators will monitor the testing to confirm that the valve has reached the desire position and to ensure the valve reached in specific time to establish the integrity of the valve's operating mechanism.
