Layers of Protection Analysis (LOPA) Services

aeSolutions provides expert Layers of Protection Analysis (LOPA) services to help industrial manufacturing facilities evaluate process risks and determine whether existing safeguards provide sufficient protection against hazardous scenarios. Our structured, semi-quantitative methodology helps teams better understand risk levels and identify where additional protection layers may be required.

​

LOPA studies are often performed following Process Hazard Analysis (PHA) studies to further evaluate high-consequence scenarios and confirm that Independent Protection Layers (IPLs) effectively reduce risk to acceptable levels. aeSolutions works closely with your facility's engineering, operations, and safety teams to develop defensible risk assessments that support safer, more resilient operations and informed decision-making.

​

Our LOPA capabilities include:​​

• LOPA study facilitation by experienced process safety professionals

• Identification and evaluation of initiating events and consequence scenarios

• Independent Protection Layer (IPL) identification and verification

• Semi-quantitative risk analysis and risk reduction evaluation

• Support for Safety Integrity Level (SIL) determination studies

• Integration with PHA, HAZOP, and broader process safety programs

• Documentation of study results and risk reduction recommendations

• Support for risk mitigation planning and implementation

With aeSolutions’ LOPA expertise, organizations can better quantify process risks, validate the effectiveness of existing safeguards, and ensure protective layers are sufficient to support safe and resilient plant operations.
