The COASTAL DRILLER, elevated in 200 feet of water with 2 knots current, 30 foot waves, and wind speeds of 60 knots may continue drilling if the maximum leg reaction is less than __________.

🔍 Key Concepts

• Jack-up rig leg reaction limits from the unit’s operating manual or stability manual • How environmental conditions (water depth, wave height, wind, current) relate to the allowable leg reaction table for that specific rig • The importance of staying below, not equal to or above, the maximum permitted leg reaction value

💭 Think About

• Which choice most closely matches the maximum allowable leg reaction given for this exact combination of water depth, wave, wind, and current for the COASTAL DRILLER? • If the condition says the rig may continue drilling, what does that imply about where your calculated leg reaction lies in relation to the maximum allowable value? • Are the options spaced in a way that suggests you should look for the exact tabulated limit rather than rounding or estimating?

✅ Before You Answer

• Verify you are using the correct row and column from the COASTAL DRILLER’s leg reaction/operating limits table for: 200 ft water depth, 2 knots current, 30 ft waves, 60 kt wind • Confirm that the condition for “continue drilling” is satisfied only when the calculated maximum leg reaction is less than the tabulated limit for that condition • Double‑check that you have not confused units: leg reactions are in kips (kilo‑pounds) and the choices differ by tens of kips, so precision matters
