Instrumented Protective Functions (IPF): Design and Verification
| 29 June – 03 July 2026, Abu Dhabi | 16 – 20 Nov. 2026, Abu Dhabi |
COURSE OVERVIEW:
The purpose of this course is to provide a rigorous engineering approach to the design, implementation, and verification of Instrumented Protective Functions (IPF) within the framework of Functional Safety standards. In high-hazard industries, IPFs serve as the final electronic layers of protection designed to prevent or mitigate catastrophic events. This program focuses on the technical requirements of the IEC 61508 and IEC 61511 standards, ensuring that safety-critical systems are engineered with the necessary reliability and integrity.
The scope of this training encompasses the entire Safety Lifecycle, from the initial Hazard and Operability (HAZOP) studies to the final decommissioning of the system. Participants will explore the methods for determining the required Safety Integrity Level (SIL) for a specific function, utilizing techniques such as Risk Graphs and Layer of Protection Analysis (LOPA). The curriculum provides a detailed look at the architecture of Safety Instrumented Systems (SIS), including the selection of certified sensors, logic solvers, and final elements.
Coverage includes the quantitative verification of IPF performance, specifically the calculation of the Probability of Failure on Demand (PFDavg). Attendees will learn how to manage the "Safe Failure Fraction," determine appropriate proof-test intervals, and ensure that the hardware meets the required architectural constraints. By focusing on both the mathematical proof and the physical installation, the course ensures that participants can design protective functions that truly provide the intended level of risk reduction.
COURSE OBJECTIVES:
After completion of this course, the participants will be able to:
- Analyze the requirements of the IEC 61508 and IEC 61511 standards.
- Differentiate between Basic Process Control Systems (BPCS) and SIS.
- Perform SIL Determination using LOPA and Risk Graph methods.
- Design IPF architectures to meet specific SIL 1, 2, or 3 targets.
- Calculate the Probability of Failure on Demand (PFDavg) for a loop.
- Evaluate the impact of "Proof Testing" intervals on safety integrity.
- Select SIL-certified sensors, logic solvers, and final elements.
- Implement "Voting Logic" (1oo2, 2oo3) for improved reliability.
- Manage the "Safe Failure Fraction" and "Hardware Fault Tolerance."
- Develop comprehensive Safety Requirement Specifications (SRS).
- Conduct Verification and Validation of the SIS design.
- Ensure compliance with Functional Safety Management (FSM) audits.
TARGET AUDIENCE:
This course is intended for Safety Engineers, Control Systems Engineers, Process Safety Managers, and Instrumentation Professionals involved in safety-critical design.
TRAINING COURSE METHODOLOGY:
A highly interactive combination of lectures, discussion sessions, and case studies will be employed to maximize the transfer of information, knowledge, and experience. The course will be intensive, 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 the learning experience. Course material will be provided in PowerPoint, with necessary animations, learning videos, and general discussions.
The course participants shall be evaluated before, during, and at the end of the course.
COURSE CERTIFICATE:
National Consultant Centre for Training LLC (NCC) will issue an Attendance Certificate to all participants completing a minimum of 80% of the total attendance time requirement.
