The COASTAL DRILLER, elevated in 150 feet of water with 0 knots current, 10 foot waves, and wind speeds of 70 knots may continue drilling if the maximum leg reaction is less than __________.

🔍 Key Concepts

• Leg reaction limits for jack-up rigs like COASTAL DRILLER • How environmental conditions (waves, wind, water depth, current) affect allowable leg loads • Where to find the maximum allowable leg reaction value in the rig’s operating manual or stability booklet

💭 Think About

• Compare the given environmental conditions (150 ft water depth, 0 current, 10 ft waves, 70 knot winds) with the rig’s leg reaction tables for that specific condition or closest match • Think about whether stronger winds and higher waves increase or decrease allowable leg reactions, and how safety margins are applied • Ask yourself: for this exact combination of conditions, what is the published maximum leg reaction before operations must stop?

✅ Before You Answer

• Confirm you are reading the correct table/row for 150 ft water depth and 70 knot wind in the COASTAL DRILLER’s manual (or exam-supplied table) • Verify the units of leg reaction (kips) and match them to the choices • Double-check that you are using the maximum allowable leg reaction, not an average or a value from a different sea state or wind speed
