In the YouTube video “Pre-Commissioning vs Commissioning – What Takes Place During Each Stage?” by Paul Turner, the importance of pre-commissioning and commissioning stages in the commissioning process is thoroughly examined. The video highlights that pre-commissioning, often referred to as vendor startup, is the initial testing of individual equipment pieces by vendors upon arrival at the worksite. This stage verifies the proper function of each piece and ensures no damage occurred during shipping or installation.
Following pre-commissioning, the equipment progresses to commissioning testing, where multiple pieces are tested together as subsystems. This phase involves the integration and verification of controls, as well as assessing interconnectivity between components.
Commissioning, as explained in the video, entails building up each part of the project to implement the overall plant process. Each subsystem is eventually integrated with others to achieve the intended purpose of the entire project.
The video emphasizes the necessity of both pre-commissioning and commissioning stages, highlighting various tests involved in the pre-commissioning phase, such as factory acceptance testing (FAT), site acceptance testing (SAT), site integration testing (SIT), and mechanical and electrical pre-commissioning tests. Skipping either stage can lead to issues that require additional time and effort to rectify. Paul Turner’s comprehensive explanation provides valuable insights into the meticulous process of preparing equipment for operation in industrial settings with the help of commissioning services.
