- العرض التوضيحي: يشمل ذلك عرض تشغيل النظام على أصحاب المصلحة للتحقق من وظائفه وقدراته المقصودة.
فوائد التحقق من النظام:
تُمتد فوائد التحقق من النظام بشكل شامل، فذلك ليس فقط لتلبية متطلبات الامتثال، بل أيضًا:
- تقليل المخاطر وتحسين السلامة: من خلال تحديد المشكلات المحتملة ومعالجتها في وقت مبكر، يقلل التحقق من مخاطر وقوع الحوادث والأعطال.
- تحسين الكفاءة التشغيلية: تُترجم الأنظمة الموثوقة إلى عمليات أكثر سلاسة، وتقليل وقت التوقف، وزيادة الإنتاجية.
- تقليل التكاليف: من خلال اكتشاف الأخطاء ومعالجة المشكلات قبل أن تصبح مشاكل باهظة الثمن، يُوفر التحقق الوقت والموارد.
- تحسين عملية صنع القرار: يوفر التحقق رؤى قيمة حول أداء النظام، مما يسمح باتخاذ قرارات أكثر استنارة فيما يتعلق بالمشاريع والاستثمارات المستقبلية.
الخلاصة:
يُعد التحقق من النظام عملية أساسية في صناعة النفط والغاز. فهو ليس مجرد وضع علامة على خانة، بل يُشكل أساسًا للعمليات الآمنة والموثوقة والكفاءة. من خلال التحقق الدقيق من أنظمتهم، يمكن لشركات النفط والغاز بناء الثقة في عملياتها، وتقليل المخاطر، وضمان مستقبل مستدام ومربح.

System Verification Exercise:
Scenario: You are a safety engineer tasked with verifying a new drilling platform's emergency evacuation system.
Task: Identify three specific methods of System Verification you would employ to ensure the system functions correctly and meets safety standards. Explain how each method would be applied in this scenario.
Exercice Correction
Here are three possible methods and their application:
- Testing: Conduct a full-scale evacuation drill simulating a real emergency. This involves activating the system, ensuring all alarms, escape routes, and safety equipment function correctly. Participants would follow established procedures to evaluate the system's effectiveness and identify any deficiencies.
- Analysis: Using simulations and modeling, analyze the evacuation process under various scenarios, such as different weather conditions, fire outbreaks, or equipment failures. This helps to identify potential bottlenecks and improve evacuation routes and procedures for maximum safety.
- Inspection: Thoroughly inspect all components of the evacuation system, including alarms, escape routes, lifeboats, and safety equipment. Verify that all components are properly installed, maintained, and in working order. This includes checking for any damage, corrosion, or wear and tear that could compromise the system's performance.

System Verification Techniques in Oil & Gas
System verification in oil and gas employs a range of techniques to ensure systems meet their intended performance, safety, and regulatory requirements. These techniques can be broadly categorized as follows:
1. Testing:
- Functional Testing: Evaluates the system's ability to perform its intended functions under various scenarios. This may include testing individual components, subsystems, or the entire system as a whole.
- Performance Testing: Assesses the system's performance against predefined metrics, such as throughput, efficiency, and response time. This may involve stress testing, load testing, and capacity testing.
- Safety Testing: Focuses on identifying potential hazards and ensuring the system's safety features are effective. This includes testing emergency shutdown systems, fire suppression systems, and other safety mechanisms.
- Environmental Testing: Evaluates the system's resilience and performance under harsh environmental conditions, such as extreme temperatures, humidity, and vibration.
- Integration Testing: Ensures the seamless integration of different components and subsystems within the overall system.
2. Analysis:
- HAZOP (Hazard and Operability Study): Identifies potential hazards and operational problems within the system. This method focuses on identifying deviations from intended behavior and analyzing their potential consequences.
- FTA (Fault Tree Analysis): A top-down approach that analyzes the potential causes of system failure and their likelihood. This helps identify weak points in the system and potential areas for improvement.
- Simulation: Utilizes computer models to simulate the system's behavior and predict its performance under various conditions. This allows engineers to test different scenarios and identify potential problems before they occur.
- Data Analysis: Analyze data collected during testing or operation to identify patterns, trends, and anomalies that may indicate potential issues.
3. Inspection:
- Visual Inspection: A physical examination of the system's components and materials to ensure they meet specified standards and are free from defects.
- Dimensional Inspection: Verifies the dimensions and tolerances of components to ensure they meet design specifications.
- Non-Destructive Testing (NDT): Uses specialized techniques to evaluate the internal integrity of materials and structures without causing damage. Examples include radiography, ultrasonic testing, and magnetic particle testing.
4. Demonstration:
- Functional Demonstration: A practical demonstration of the system's intended functionality to stakeholders, including operators, regulators, and clients.
- Simulation Demonstration: Demonstrates the system's behavior using simulations, providing a visual and interactive representation of its performance.
Choosing the Right Techniques:
The specific techniques employed for system verification depend on the nature of the system, its complexity, and the specific requirements. A comprehensive verification process often involves a combination of these techniques to ensure a thorough evaluation.
