COURSE OVERVIEW:

The purpose of this course is to provide specialized technical knowledge regarding the design, implementation, and maintenance of Safety Instrumented Systems (SIS) and Emergency Shutdown (ESD) systems. These systems act as the final automated layer of defense in industrial facilities, designed to take the process to a "safe state" when operating parameters exceed pre-defined limits. This program focuses on the high-integrity hardware and logic solvers required to protect life, the environment, and capital assets from catastrophic events.

The scope of this training encompasses the entire safety lifecycle as defined by international standards, from initial hazard identification to the decommissioning of the system. Participants will explore the technical requirements for safety-rated sensors, logic solvers (such as Triple Modular Redundant systems), and final control elements like block valves. The curriculum is specifically designed to address the balance between safety, availability, and the avoidance of "nuisance" or spurious trips that can cause unnecessary economic loss.

Coverage includes the practical aspects of Proof Testing, Safety Integrity Level (SIL) verification, and the rigorous documentation required for regulatory compliance. Attendees will learn how to interpret Safety Requirement Specifications (SRS), manage bypasses and overrides safely, and troubleshoot fail-safe circuits. By focusing on the practical application of safety engineering, the course ensures that participants can maintain the systems that prevent disasters in high-risk environments like oil refineries, gas plants, and chemical facilities.

COURSE OBJECTIVES:

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

• Analyze the role of SIS within the "Layers of Protection" (LOPA) framework.
• Differentiate between Basic Process Control Systems (BPCS) and SIS.
• Identify the requirements for SIL 1, SIL 2, and SIL 3 classifications.
• Evaluate hardware fault tolerance and voting logic (1oo2, 2oo3, etc.).
• Understand the operation of Triple Modular Redundant (TMR) logic solvers.
• Execute Proof Testing procedures for safety-rated sensors and valves.
• Utilize Partial Stroke Testing (PST) to verify ESD valve functionality.
• Manage "Force" and "Bypass" registers according to safety protocols.
• Identify fail-safe vs. fail-danger failure modes in instrumentation.
• Interpret Cause and Effect (C&E) diagrams for emergency logic.
• Document safety system modifications under strict Management of Change (MOC).
• Troubleshoot safety loops without compromising plant protection.

TARGET AUDIENCE:

This course is intended for Safety Engineers, Instrumentation Technicians, Control Systems Specialists, and Operations Supervisors in hazardous industries.

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.
