🔍 Key Concepts

• Operational limits for jack-up rigs in their Operating Manual or stability booklet • Effect of increased wind speed on required leg penetration for stability and leg strength • Difference between afloat condition vs elevated (jacked-up) condition

💭 Think About

• How does higher wind speed affect the overturning moment on a jack-up like COASTAL DRILLER, and what does that usually mean for how far the legs must be lowered? • Compare each option with what seems realistic for providing additional seabed reaction and structural strength at more than 70 knots of wind. • Think about whether a very small change in leg penetration (like around 1 foot) could realistically make a big difference in stability at very high winds.

✅ Before You Answer

• Check what the stability/leg strength tables or curves for COASTAL DRILLER specify for wind speeds above 70 knots. • Verify whether the condition in the question is fully elevated (legs firmly on bottom) or only partially lowered while still afloat. • Confirm that the distance chosen is consistent with typical safety margins used for jack-up rigs in severe weather.
