Question 3865 Deck General

The correct answer is D) Load Line mark. The maximum draft to which a MODU (Mobile Offshore Drilling Unit) can legally be submerged is indicated by the Load Line mark. The Load Line is a physical mark on the hull of a vessel that indicates the maximum draft or depth to which the vessel can be safely loaded. This is regulated by international agreements like the International Convention on Load Lines, which sets requirements for load lines on different types of vessels, including MODUs. The other options are incorrect because: A) the Certificate of Inspection does not directly specify the maximum draft, B) the Tonnage mark indicates the vessel's tonnage, not its maximum draft, and C) the Muster List ("Station Bill") provides information on crew emergency duties, not the vessel's maximum draft.
