🔍 Key Concepts

• Intact stability of jack-up rigs and how it differs from conventional ships • The relationship between righting arm (GZ) curve and maximum stability angle • Physical meaning of deck edge immersion, loll, downflooding, and load line on a floating or elevated unit

💭 Think About

• Think about what happens to the jack-up’s ability to resist heeling as the angle of heel increases: at what point is the righting moment at its greatest? • Which of the listed events (deck edge immersion, loll, downflooding, or reaching the load line) is most closely tied to the point where the righting arm curve peaks? • Consider which option represents a stability condition versus which represent operational/structural limits or emergencies.

✅ Before You Answer

• Identify which of the four choices is directly linked to the maximum value of the righting arm (GZ) curve. • Distinguish between stability-related phenomena (like loll) and geometric or regulatory reference points (like deck edge or load line). • Verify which event typically occurs at or near the angle where stability begins to decrease after reaching its maximum.
