Question 2640 Deck General

The correct answer is A) 12 months. According to U.S. Coast Guard regulations, cargo discharge piping on vessels must be tested for integrity at least once every 12 months. This requirement is specified in 46 CFR 61.10-5, which states that all cargo piping systems must be pressure tested annually to ensure they are in safe working condition. The other options are incorrect because 6 months is too frequent, 24 months is too infrequent, and 18 months does not align with the 12-month regulatory requirement.
