A jack-up has 8 inches of trim by the stern. Calculations show that the moment required to change trim one inch is 500 foot-kips. To level the unit, how far must a weight of 50 kips be transferred toward the bow?

🔍 Key Concepts

• Trim by the stern and what it means to "level" the vessel/unit • The definition and use of Moment to Change Trim 1 Inch (MT1") • The relationship: trimming moment = weight × distance

💭 Think About

• First, figure out the total change in trim (in inches) needed to go from the current condition to level. • Use the given MT1" value to find the total trimming moment required for that change in trim. • Finally, relate that trimming moment to the 50‑kip weight moved some distance toward the bow, and solve for the unknown distance.

✅ Before You Answer

• Confirm you are using total trim change in inches (not feet) with the MT1" value. • Make sure your trimming moment units stay consistent: foot‑kips for both MT1" and weight × distance. • Before choosing an answer, check if your calculated distance is reasonable compared to the vessel’s likely length and matches one of the options.
