Potential disasters at an industrial processing plant may include an accident resulting in a massive release of toxic materials, an uncontrollable reactant, a devastating explosion or any combination of the above. All processing plant must be guarded from all potential disaster scenarios. Therefore , emergency shutdown valves has to be sure be operated with fault-free as the valves are kept idle in open position for long periods and are designed to close and keep tight in case of a hazard occur. Regular checking has to be perfonned in order to guarantee the function of the valves. Emergency Shutdown valves have been tested at unit turnaround, using a Full Stroke Testing and Partial Stroke Testing to demonstrate the perfonnance. The scope of this project is to verify the technology needed for Full Stroke Testing and Partial Stroke Testing in order to ensure the perfonnance of the Emergency Shutdown valve. The testing is simulated by using WideField2 Software (YOKOGAWA) for Full Stroke Test and FieldCare Software (Metso Neles) for Partial Stroke Test. Partial Stroke Testing can be a good complement to Full Stroke Testing as it reduces the required Full Stroke Testing frequency and associated operational impact. Partial Stroke Testing will detect failure of Emergency Shutdown valves without disturbing the process flow. Testing is conducted for sixth times. The valve status and its response to mechanical movement during the test are monitored. Valve perfonnance trend is analyzed after each partial stroke test to find whether there is any potential of valve failure. The result of valve test, pneumatics test, breakdown pressure and load factor are being taken into consideration in analyzing the perfonnance of the emergency shutdown valve.
