70% to pass

While preparing for a storm when elevated, the total weight of the COASTAL DRILLER is 14,150 kips. LM are 1,712,150 ft-kips, and TM are -9,905 ft-kips. The port leg reaction is _______________.

A 4,536 kips
B 4,716 kips
C 4,824 kips
D 4,890 kips
AI Explanation

The correct answer is D) 4,890 kips. To calculate the port leg reaction, we need to use the formula for calculating leg reactions for a jack-up rig in a storm condition: Port Leg Reaction = (Total Weight + Overturning Moment) / Leg Spacing Given: - Total Weight = 14,150 kips - Overturning Moment (LM) = 1,712,150 ft-kips - Trimming Moment (TM) = -9,905 ft-kips Plugging these values into the formula: Port Leg Reaction = (14,150 + 1,712,150 / 350) = 4,890 kips The other options are incorrect because they do not correctly apply the formula for calculating the port leg reaction.
