5.2.3Process Safety Reporting
A Loss of Primary Containment (LOPC) is defined as an unplanned or uncontrolled release of any material from primary containment, including non-toxic and non-flammable materials (e.g. steam, hot condensate, nitrogen, compressed CO2 or compressed air).
A Tier 1 or Tier 2 PSE is defined as an LOPC from a process system that meets criteria defined in API RP 754.
LOPC events are reported in SBM Offshore’s Reporting System as highlighted in sections 2.1.2 and 5.3. This system includes a built-in calculation tool to assist the user in determining the release quantity of LOPC events. All LOPCs are analysed to identify those considered to be PSEs as per API RP 754. Process Safety KPIs used by SBM Offshore include the number of Tier 1 and the number of Tier 2 PSEs.
SBM Offshore encourages employees and contractors to report the PSE Tier 3 (minor LOPC, precursors, etc.), using them as a basis for leading initiatives aiming at minimizing the probability of major events occurring.
