CSWIP 3.1U Practice Questions - CSWIP 3.1U Underwater (NDT) Inspection Diver Exam

How does Close Visual Inspection (CVI) differ from General Visual Inspection (GVI) during a CSWIP 3.1U subsea survey?

CVI is conducted entirely using ROVs without diver intervention. CVI requires localized surface cleaning down to bare metal or tight marine growth removal to examine specific details and welds. CVI is restricted to top-side splash zone structural members only. CVI replaces all non-destructive magnetic and ultrasonic testing requirements.

Correct Answer:

CVI requires localized surface cleaning down to bare metal or tight marine growth removal to examine specific details and welds.
