Summary of Operation Boundaries (SOOB)

A summary of defeating factors (either single or in combination) that have the potential to exceed the tolerability limits of safe operations. These defeating factors are qualitatively determined using experience and establish the boundaries in which operations are carried out. Other Related Terms and Definitions: Shell EP95-0010 (Revision 1 – 25 Jan 2001) – (Manual of Permitted Operations – MOPO) – Manual of Permitted Operations defines the limits of safe operation when barrier effectiveness is reduced. The limit of safe operation permitted during periods of escalated risk in either likelihood or consequence. The limit of safe operations if the barriers are reduced, removed, or purposely defeated.

SHIDAC

Structured Hazard Identification, Assessment and Control (SHIDAC) Process incorporating the basics of fault-tree and event-tree, implementing measures to control hazards and to recover in case of barrier failure. A key deliverable is the identification or determination of Critical Activities or Tasks that ensure the identified Barriers are established, maintained and effective. The steps are:
  1. Identify the hazards
  2. Assess the potential consequences, their likelihoods and their associated risks
  3. Identify hazard Control Barriers to prevent release, and
  4. Identify Defence Barriers to protect people, assets, environment and reputation in the event of such a hazard release.
