LOPA Course

Why does business need the LOPA method?

1. Cost reduction at project stage: achieving optimal "cost-safety" ratio

   Due to regulatory requirements to implement safety systems at hazardous production facilities, when designing or modernizing facilities, operators often play it safe by installing SIL3 level safety elements, which significantly increases CAPEX and OPEX (SIL3 can be several times more expensive than SIL1).

   LOPA methodology allows selecting adequate protection measures with high justification, avoiding excessive costs.

2. Quantitative risk assessment considering protection measures

   The LOPA method allows quantitative assessment of risk level considering protection measures identified during HAZOP sessions. This helps reduce costs for construction, technical re-equipment, or modernization of hazardous production facilities at the design stage.

3. Facilitating project documentation approval

   Joint application of LOPA and HAZOP makes design solutions more justified and transparent, which facilitates documentation approval in Glavgosexpertiza of Russia.

4. Obtaining license for operating hazardous production facilities

   LOPA analysis results can be used when developing Emergency Response Plans - one of the key documents for obtaining a license.

5. Updating industrial safety declaration

   LOPA helps update data on risks and protection measures during operation of hazardous production facilities.

6. Risk identification and operational cost reduction

   The method allows assessment of existing protection measures at operating facilities and making decisions on their adjustment aimed at reducing operational expenses.

The principle of LOPA analysis consists in assessing the adequacy of independent protection layers of the facility against risk realization. If existing protection measures are insufficient, the required safety integrity level SIL of the safety system is determined.
