3 Key Integrity Barriers Topic 16 – Emergency Shutdown (ESD) and Blowdown Systems • Emergency shutdown systems are installed on plants to provide a mechanism to shut down the plant safely in the event of an emergency. ESD is usually triggered automatically if some key process parameter has been exceeded or a fire/gas release has been detected, or may be manually initiated if personnel believe that they are no longer able to ensure safe control of the plant. • Blowdown systems provide a means to rapidly depressurise the plant by removing the gas inventory to a safe location (e.g. a flare). • These systems are required to be functional when called upon to take action. In order to do this end-to-end tests of the systems (including sensors, control system and final control elements) have to be conducted periodically to ensure that the system is robust and ready to respond if/when required. HSSE Management Tours: Asset Integrity Guide • The key areas in ensuring ESD and blowdown system functionality are: – A robust process(s) for system function testing of all components – Ensuring that function tests are actually carried out and the results recorded for analysis – Review of results and follow up on any deficiencies found • Certain testing activities may require one or a number of devices to be isolated, and it is therefore important to fully understand what functions are being withdrawn in this period and that any risks are fully assessed. 40
3 Key Integrity Barriers Topic 16 – Emergency Shutdown (ESD) and Blowdown Systems 1. How do we make sure that ESD and blowdown systems will work when needed? 2. What happens when deficiencies are found in the system(s)? 3. Can you describe to me where testing records are kept and what is done with them? Questions 4. Who is technically responsible for the ESD and blowdown systems? How do they get involved? 5. Are there any parts of these systems isolated at the moment and what is the reason? Is this a recent change? 41
