COURSE OVERVIEW:

This advanced course provides a practical and structured understanding of how Hazard Identification and Risk Assessment (HIRA) is supported and strengthened by Layer of Protection Analysis (LOPA) and Safety Integrity Level (SIL) classification. The course explains how to move from qualitative hazard studies (such as HAZID and HAZOP) into semi-quantitative LOPA, determine whether existing safeguards are adequate, and define additional risk reduction requirements.

Participants will learn how to develop LOPA scenarios, quantify initiating event frequencies, evaluate Independent Protection Layers (IPLs), and classify SIL targets in line with corporate and international requirements. Through multiple group exercises and relevant examples, participants will gain the confidence to apply LOPA methodology, understand residual risk, and contribute effectively to LOPA and SIL workshops within their organisation.

COURSE OBJECTIVES:

After completion of this course, the participants will be able to:

-Explain the relationship between HIRA, HAZOP, LOPA, and SIL classification within the overall process safety and risk management framework.

-Describe the key concepts, terminology, and principles of the LOPA methodology.

-Develop LOPA scenarios starting from hazard identification and initiating events, including definition of consequences, frequencies, and safeguards.

-Select appropriate frequency targets for mitigated event likelihood in accordance with corporate risk criteria.

-Identify sources of initiating event frequency data and understand their limitations and uncertainty.

-Describe the characteristics of effective Independent Protection Layers (IPLs) and the requirements for independence, integrity, auditability, and response.

-Identify sources of probability of failure on demand (PFD) data for IPLs and understand how PFD is used in LOPA calculations.

-Perform basic LOPA calculations to determine whether existing safeguards achieve the required risk reduction.

-Determine SIL classification requirements where gaps exist between residual risk and tolerable risk criteria.

-Participate effectively in, and where appropriate lead, LOPA study teams and SIL determination workshops.

-Apply LOPA and SIL results to support recommendations, action tracking, and follow-up within the company's HIRA and process safety management system.

TARGET AUDIENCE:

-Process Engineers and Senior Process Engineers

-HSE and Process Safety Engineers

-Operations and Production Engineers and Supervisors

-Instrumentation, Control, and Safety System Engineers

-Project and Design Engineers involved in safety studies and modifications

-Risk, Assurance, and Audit personnel supporting HIRA and LOPA activities

TRAINING COURSE METHODOLOGY:

A highly interactive combination of lectures and discussion sessions, as well as case studies, will be managed to maximize the amount and quality of information, knowledge, and experience transfer. The course will be intensive but practical and highly interactive. The sessions will start by raising the most relevant questions and motivating everybody to find the right answers. The attendants will also be encouraged to raise more of their questions and to share in developing the right answers using their analysis and experience. There will also be some indoor experiential activities to enhance learning. Course material through PowerPoint equipped with necessary animation, learning videos, and general discussions will be provided.

The course participants shall be evaluated before, during, and after the course.
