🔍 Key Concepts

• Load line draft and when it applies to mobile offshore drilling units (MODUs) • Differences between column-stabilized units and bottom-supported units • Situations where a unit is transitioning between floating and bottom-supported conditions

💭 Think About

• Ask yourself: In which situation is the unit NOT in its normal floating, transit condition for which the load line is intended? • Which option describes a short-term, controlled operation rather than a normal seagoing voyage? • Which scenario clearly involves a vertical movement relative to the seabed, not a horizontal tow between locations?

✅ Before You Answer

• Identify which options involve column-stabilized vs bottom-supported units and how that affects buoyancy and draft control • Check which scenario is a temporary operational evolution (like positioning or jacking) rather than normal navigation • Verify which situation would make strict application of the assigned load line draft impractical during that specific, brief operation
