🔍 Key Concepts

• how different soil types (soft mud, clay, sand, silt) resist penetration and provide side friction on a jack‑up rig's legs • relationship between leg penetration depth and the buoyant force of the hull needed to pull the legs back out • which soil type is most likely to create very high pullout resistance once a leg has been driven deep

💭 Think About

• Think about which seabed material will "grab" or bond to the leg over a large surface area, making it very hard to extract once deeply embedded. • Consider which material, when penetrated deeply, will rely more on skin friction along the leg rather than just bearing at the tip. • Ask yourself: in which soil would a leg be more likely to become so "stuck" that the hull’s buoyancy alone might not provide enough upward force to free it?

✅ Before You Answer

• Compare the drainage and cohesiveness of clay, mud, sand, and silt, and how that affects pullout resistance. • Focus on which soil type develops high adhesion and side friction on steel legs during deep penetration. • Verify which of the options is commonly associated with very high extraction forces for jack‑up legs in offshore operations.
