Keeping the draft of a MODU at or below the load line mark will ensure that the unit has adequate __________.
• Load line mark and what it represents for vessel safety • Difference between buoyancy, displacement, and ballast • Why maintaining a certain draft is critical for a MODU’s (Mobile Offshore Drilling Unit’s) survivability in heavy weather or damage conditions
• Ask yourself: What is the main safety purpose of a load line? Is it about weight carried, motion behavior, or how much of the hull stays above water? • Which term describes the volume of watertight structure above the waterline that can keep the unit afloat if it is damaged or takes on water? • Which options are clearly NOT something you "ensure" simply by limiting draft to a marked line on the side of the hull?
• Verify which option directly relates to how much watertight hull remains above the waterline. • Eliminate any option that is more about weight of the vessel itself rather than its ability to stay afloat when damaged. • Check that the term you choose is commonly linked to load line regulations and intact stability requirements.
