Question 1718 Deck General

The correct answer is D) above 32 degrees North and below 32 degrees South. The immersion suit requirements for Offshore Supply Vessels (OSVs) operating in the Atlantic Ocean apply to units operating above 32 degrees North and below 32 degrees South, as per the regulations outlined in 46 CFR 28.110. This is because these are the regions where water temperatures are cold enough to require the use of immersion suits to protect personnel in the event of an emergency at sea. The other answer choices are incorrect because they specify different latitude ranges that do not accurately reflect the actual regulatory requirements for immersion suit usage on OSVs in the Atlantic Ocean.
