The COASTAL DRILLER, elevated in 100 feet of water with 0 knots current, 30 foot waves, and wind speeds of 50 knots may continue drilling if the maximum leg reaction is less than __________.

🔍 Key Concepts

• Maximum leg reaction limits for a jack-up drilling rig under specified environmental conditions • How wave height, wind speed, and water depth affect structural loading on the legs • Required safety margins between calculated leg reaction and the allowable limit

💭 Think About

• Given 100 ft water depth, 30 ft waves, and 50-knot winds, should the allowable maximum leg reaction be just equal to, or comfortably above, the calculated reaction? • If the rig may continue drilling when the maximum leg reaction is less than a certain value, what does that tell you about the relationship between the calculated reaction and the allowable design limit? • Look at the pattern of answer choices—are they close together or spaced in a way that suggests a design limit value rather than a random number?

✅ Before You Answer

• Confirm you understand that kips means kilo-pounds (1,000 pounds of force) • Think about which option most reasonably represents an allowable maximum leg reaction (a design limit) under severe but still operational conditions, not survival-only conditions • Double-check that the phrase "may continue drilling if the maximum leg reaction is less than" means you are choosing the threshold limit, not the current calculated load
