What is the initial step to take during an internal inspection of a vessel?

Reading the previous inspection reports is a crucial initial step during an internal inspection of a pressure vessel. These reports provide valuable insights into the vessel's historical data, including previous issues, repairs, and any areas noted for particular attention. This context helps inspectors understand the vessel’s condition better, making them more aware of potential problems that may have developed since the last inspection.

Additionally, reviewing earlier findings can guide the inspector's focus during the current evaluation. Understanding trends in deterioration, previous corrosion patterns, or past repairs allows for a more thorough and informed inspection. This foundational step ensures that the inspector is adequately prepared to identify any recurring issues or newly developed concerns.

While performing visual inspections and checking safety equipment are important components of the overall inspection process, they typically follow the review of historical documentation. The chain of action often begins with gathering existing information before directly assessing the vessel's condition. This structured approach emphasizes the importance of knowledge and preparation in ensuring effective inspection practices.
