All alterations to pressure vessels must be authorized by whom?

• A. Authorized inspector
• B. Pressure vessel engineer
• C. Authorized inspector and the pressure vessel engineer
• D. Authorized inspector or the pressure vessel engineer

Answer: (C)

The requirement for all alterations to pressure vessels to be authorized by both an authorized inspector and a pressure vessel engineer stems from the critical importance of ensuring safety and compliance with applicable codes and standards. An authorized inspector plays a vital role in evaluating the integrity of the pressure vessel and ensuring that any changes meet safety regulations. Their expertise in assessing materials, fabrication techniques, and inspection standards is crucial to ensure that the alterations do not compromise the vessel's structural integrity. On the other hand, the pressure vessel engineer is responsible for assessing the design and engineering aspects of the alterations. This includes ensuring that any changes align with engineering principles and safety requirements. The engineer's knowledge is essential for evaluating how proposed modifications may affect the vessel's performance, including stress distribution, material compatibility, and compliance with relevant codes. By necessitating authorization from both the authorized inspector and pressure vessel engineer, the regulations ensure a comprehensive assessment that addresses both inspection and engineering viewpoints, thereby significantly minimizing the risk of failure or accidents. This collaborative approach enhances the safety and reliability of pressure vessels after alterations are made.
