Question 2545 Deck General

The correct answer is D) All of the above. According to U.S. regulations, the Oil Record Book must record all operations involving oil cargo on a tank-to-tank basis. This includes the discharge overboard of any bilge water accumulated in machinery spaces, the loading or unloading of any or all oil cargo, and any internal transfer of oil cargo during a voyage. All of these operations must be accurately recorded in the Oil Record Book as per the applicable regulations. The other options are incorrect because they do not fully encompass the scope of operations that must be recorded. Option A only covers the discharge of bilge water, while option B and C are limited to specific cargo operations, rather than the full range required by the regulations.
