Design Review: This is the initial stage of commissioning, where the design plans and specifications of the system or facility are thoroughly examined. The purpose is to ensure that the design meets all the required standards, codes, and regulatory requirements. Any potential issues or discrepancies are identified and addressed before proceeding to the next stages. Factory Acceptance Testing (FAT): During the FAT, the equipment and components of the system are tested at the manufacturing facility where they were produced. The tests are conducted to verify that the equipment functions as per the specified requirements. It ensures that the components are of high quality and meet the agreed-upon standards before they are delivered to the installation site. Installation Verification: This level involves checking and confirming that the equipment and components are installed correctly at the intended location. The installation process is evaluated to ensure compliance with the design specifications and manufacturer’s recommendations. Start-Up Pre Functional Tests: Before the system is fully operational, start-up pre-functional tests are performed. These tests are focused on verifying individual components and subsystems to ensure they are functioning properly and are ready for integration. It helps identify and rectify any issues before moving on to more comprehensive testing. Functional Tests: Functional testing is conducted to assess the entire system as a unified entity. The goal is to confirm that the system is performing all its intended functions correctly and efficiently. This step is critical to ensuring that the system operates as expected and meets the defined performance criteria. Integrated Testing: Integrated testing takes commissioning a step further by examining the interaction and performance of different systems that may be interconnected. The purpose is to ensure that all the integrated components work seamlessly together and do not cause any conflicts or malfunctions. Throughout the commissioning process, thorough documentation is maintained, including test procedures, results, and any corrective actions taken. Commissioning is essential to deliver a reliable and fully functional system that meets the user’s requirements and operates efficiently and safely. It’s worth noting that the commissioning process can vary depending on the complexity and type of system being commissioned, and there might be additional levels or steps based on specific project requirements.
