🔍 Key Concepts

• Meaning of LCG (Longitudinal Center of Gravity) and TCG (Transverse Center of Gravity) in relation to a jack-up’s legs • What is meant by the leg centroid when a unit is elevated • How vertical alignment of the unit’s CG with the leg centroid affects load sharing between legs

💭 Think About

• If the LCG and TCG are positioned exactly over the leg centroid, how would the total vertical load from the hull tend to distribute among the legs? • Which option talks about how the load is shared between the legs, versus options that talk about seabed conditions or drilling/preloading operations? • Think about which effect happens immediately from geometric alignment of centers (CG and leg pattern), rather than from changes in environment or operational steps.

✅ Before You Answer

• Identify which answer choice directly concerns load distribution among legs rather than seabed erosion or operational loads. • Ask yourself: if all legs are the same and the CG is at the leg centroid, would any leg be expected to carry more or less load than another? • Eliminate options that mainly relate to seabed scour or specific operational phases (preloading/drilling), rather than the basic static geometry of weight versus leg layout.
