Which reference provides specific guidance for inspection, prevention and repair of corrosion onboard ships?

• A. JFMM VI
• B. NSTM 631
• C. CCIMS
• D. NAVEDTRA 12345

Answer: (A)

Corrosion control on ships is guided by a dedicated reference that gives concrete procedures for inspecting for corrosion, preventing it, and repairing affected areas. The best fit here is the Corrosion Control manual in the Naval Ships Technical Manual, which lays out inspection criteria, prevention methods (such as coatings, materials, and cathodic protection), and approved repair techniques for various ship systems and hull regions. This makes it the authoritative source for onboard corrosion guidance. The other references don’t provide the same comprehensive, shipwide corrosion-specific guidance: one is a general maintenance manual, another is a system or data-management tool, and the last is a training text that doesn’t serve as the technical standard for corrosion inspection and repair.
