Question 520 Deck General

The correct answer is D) 5 years. The reasoning behind this is that according to U.S. Coast Guard regulations, for vessels fitted with cargo gear, an initial test of the units under a proof load must be conducted, and subsequent tests and examinations of the same nature must be carried out at intervals not exceeding 5 years. This is to ensure the ongoing safety and reliability of the cargo gear. The other options are incorrect because they do not align with the 5-year interval requirement specified in the Coast Guard regulations for periodic testing of cargo gear on vessels.
