NBIC guidelines primarily govern which aspect of vessel work?

• A. Repair or alteration of pressure vessels
• B. Electrical system design
• C. Paint and coating schedules
• D. Shipping and transport regulations

Answer: (A)

NBIC, the National Board Inspection Code, focuses on making sure repairs and alterations to boilers, pressure vessels, and piping are done safely and documented properly. It lays out the approved methods for workmanship, materials, welding or brazing, nondestructive testing, inspections, pressure testing, and the stamping or verification of the vessel after work. This ensures that any changes or repairs keep the vessel safe for continued service and are traceable to a recognized standard. It doesn’t govern electrical system design, painting or coating schedules, or shipping and transport regulations, which are governed by other codes and authorities.
