Shop Inspection Exercise

Scenario: You are the owner's representative on an oil & gas project. You are scheduled to perform a Shop Inspection of a newly fabricated pressure vessel.

Task: Create a checklist of essential items to be inspected during the Shop Inspection. Include at least five specific inspection points for each category.

Example Checklist:

Visual Inspection:

• • Verify the vessel's overall dimensions match the approved drawings.
• • Inspect the welds for any visible defects (cracks, porosity, etc.).
• • Check for proper material identification markings.
• • Assess the condition of the vessel's exterior (corrosion, dents, scratches).
• • Ensure all openings and connections are appropriately labeled and identified.

Dimensional Verification:

• • Measure key dimensions (length, width, height) and compare to drawings.
• • Verify the thickness of the vessel walls and compare to specifications.
• • Check the diameter of the vessel's openings and connections.
• • Ensure the position of the vessel's nozzles is correct.
• • Verify the location and size of any manways or access hatches.

Material Verification:

• • Check the material certifications for the vessel's construction.
• • Verify the material type (steel grade, etc.) matches the specifications.
• • Inspect the material for any visual signs of defects (inclusions, etc.).
• • Ensure the heat treatment process was correctly applied.
• • Verify the supplier of the materials and their reputation.

Non-destructive Testing (NDT):

• • Conduct ultrasonic testing to detect internal flaws in the welds.
• • Perform radiographic inspection to assess the weld quality.
• • Apply magnetic particle inspection to identify surface cracks.
• • Consider penetrant testing for surface cracks.
• • Document the NDT results and any findings.

Functional Testing (if applicable):

• • Perform pressure testing to verify the vessel can withstand design pressure.
• • Conduct leak testing to ensure the vessel is airtight.
• • Verify the operation of any internal components or devices.
• • Test the vessel's ability to maintain pressure over time.
• • Document the test results and any observed performance data.

Documentation Review:

• • Examine the welding procedures used in the vessel's fabrication.
• • Review the manufacturing records to ensure proper quality control measures were applied.
• • Check the material test reports for the vessel's components.
• • Verify the vessel's design calculations and analysis.
• • Collect all relevant documentation and records.
