On an FPSO there are typically three main
safety instrumented systems
• Process Shutdown System (PSS) –
detects potentially dangerous conditions
and executes process shutdowns
• Fire and Gas System (FGS) – detects gas
release or fire, and executes fire fighting
and other mitigation actions
• Emergency Shutdown System (ESD) –
executes process depressurisation
(blowdown), electrical isolations and other
global shutdown functions
