Emergency shutdown  (ESD) Safety Instrumented System (SIS) is designed to prevent or mitigate the plant operation from the consequences of emergency situations which may otherwise pose unacceptable risk to plant itself, public or environment.

As soon as the triggering condition is detected, ESD system immediately shuts down the plant in a safety manner in order to avoid further risk.
HIMA ESD systems, together with HIMA Slovakia expertise in pipeline & control management system FlexSILon® PMC make us the best partner for your pipeline safety and its effective operation.

ESD –The Highlights:

  • Prevents hazardous situation from occurring
  • Built to isolate hazardous sections of pipeline (for gas pipelines also depressurize hazardous sections)
  • Based upon HAZOP study and further design
  • Designed to safely stop the plant on triggering conditions
  • Power failure must not prevent safe shutdown
  • Extremely high reliability and availability
  • No spurious trips = no production loss
  • Product portfolio of HIMA safety systems up to the most demanding SIL 4 class.

The Emergency Shutdown system is in a need of a high Safety Integrity Level, typically SIL 2 up to 4. Product portfolio of HIMA safety systems is able to fulfill the most demanding SIL 4 class. Safety levels apply also to communication channels which must be guarded by robust and safe protocol, such as HIMA’s safeethernet.

Example of a plant requiring a distributed ESD SIS is a long-distance pipeline, which is area of expertise of HIMA Slovakia.
