Question 1 of 27070

🔍 Key Concepts

• Damage stability criteria for mobile offshore drilling units (MODUs) like COASTAL DRILLER • Relationship between displacement (total weight of the unit) and allowable stability limits • How exceeding a maximum displacement affects GM, KG, and righting arm curves

💭 Think About

• Think about why a maximum displacement limit would be set for a drilling unit that already has KG and watertight integrity requirements—what extra risk does higher weight introduce? • Consider which displacement value would be consistent with a realistic operational limit, not a light-ship or extreme value. • Ask yourself: if you pick too high a displacement, would the unit still reasonably be able to meet all the other listed criteria at the same time?

✅ Before You Answer

• Verify that displacement here is the total operating weight (including variable load), not just light-ship weight. • Check that the value you choose would allow the unit to maintain positive stability margins after assumed damage per the damage stability criteria. • Ensure the displacement is below the point where the KG limit curve (or KGL/KGT limits) would likely be exceeded for a typical operating load condition.
