If NDE is substituted for a pressure test after a major repair on an in-service vessel, who must approve this substitution?

• A. Just the Inspector
• B. Just the Engineer
• C. Either the Inspector or Engineer
• D. Both the Inspector or Engineer

Answer: (D)

The approval for substituting non-destructive examination (NDE) in place of a traditional pressure test following a major repair on an in-service vessel requires consent from both the Inspector and the Engineer. This joint approval is essential as it ensures that technical and safety considerations are both addressed comprehensively. The Inspector's role is crucial as they have the expertise to evaluate the vessel's integrity and ensure that the NDE methods applied are suitable for verifying the repair's quality and the vessel's overall condition. The Engineer's involvement is equally vital because they have the technical knowledge to assess whether the NDE can adequately substitute for the mechanical properties and structural integrity verification that a pressure test typically provides. This collaborative approach between the Inspector and Engineer helps ensure that the decision to use NDE instead of a pressure test adheres to industry standards and the specific code requirements relevant to the vessel's operation and repair history. The safety implications of such a decision necessitate that both professionals are in agreement before proceeding.
