Aon Energy Risk Engineering - Process Hazards Analysis and Layer of Protections Analysis
Raising the Bar in PHAs/LOPAs.
A process hazard analysis (PHA) is one of the most important elements of the process safety management (PSM) program. Most PSM-covered sites are in their fourth cycle of PHA revalidations. Some approach this as a regulatory-required “check the box” task, even though process safety incidents continue to occur and investigations often find the PHA did not identify the cause or consequence. You can not engineer protective designs and safeguards for consequences you have not identified.
Recognized Experts
Aon Energy Risk Engineering’s professionals have led over 3,500 PHA studies and over 1,500 LOPA studies. Our experienced PHA leader and scribe teams help maximize the value of your PHA team time while challenging the team to raise the bar in process hazard analysis by:
- Systematically identifying causes, potential consequences and current safeguards
- Guiding the team to uncover potential low likelihood, high hazardous consequences so safeguards can be identified and evaluated
- Ensuring your corporate procedures are followed throughout the study
- Providing high-quality documentation that meets both regulatory and your corporate requirements
Experienced Facilitators means Value Added
Aon’s Energy Risk Engineering PHA facilitators have more than 20 years of practical experience in refining and chemical manufacturing. We bring technical and operational depth to your team make-up, in addition to being trained on the specific process hazard analysis methodology being used. Our leaders use their industry experience to help guide the team to formulate cost-effective recommendations, when justified, to improve the integrity of your process.
If you are designing, engineering or constructing a new process, we can help you with third party leadership of your Hazard Identification (HAZID) or your Initial PHA.
Many PHA teams now utilize the Layer of Protection Analysis (LOPA) methodology to more objectively determine if the existing safeguards are adequate. Our PHA Facilitator/Scribe teams are trained to lead LOPAs, either integrated through out or at the conclusion of the PHA.
