🔍 Key Concepts

• Jack-up rigs vs. other mobile offshore drilling units (MODUs) and how they are supported while drilling • Difference between independent-leg and mat-type jack-ups • Effect of seafloor conditions (firm/soft, even/uneven) on leg foundations and stability

💭 Think About

• Think about how independent legs can adjust to different heights. In what situation would that be more useful: flat/even or sloping/uneven seabeds? • Consider what happens if the bottom is very soft and the load is carried on narrow legs instead of a broad mat. Which is more likely to punch in or settle unevenly? • Ask yourself: do independent-leg designs spread the load out more or concentrate it more? What kind of bottom is better for that?

✅ Before You Answer

• Match independent-leg design with the type of seabed topography it handles best (even vs. uneven) • Consider which bottoms need a mat-type jack-up to spread the load (typically softer, more uniform soils) • Eliminate any answer that confuses water depth limits of jack-up rigs with bottom conditions—jack-ups have depth limits, but this question is about seafloor characteristics, not just depth
