🔍 Key Concepts

• Jack-up rig leg strength requirements for ocean transit with limited wind conditions (less than hurricane strength) • Relationship between Tip of Can (TOC) position, leg length exposed below the hull, and bending loads on the legs in transit • Difference between harsh environment / storm survival positions vs. normal ocean transit positions

💭 Think About

• How does raising or lowering the legs change the bending moment on the legs when the rig is in a seaway? Think about where the waterline is relative to the hull and the leg truss. • For winds not expected to exceed 70 knots, would class/operating manuals typically require the legs to be fully retracted, partially extended, or in a deep-storm survival position during ocean transit? • Which option looks more like a "flush" or "nearly flush" transit setting versus a large, storm-survival leg projection below the hull?

✅ Before You Answer

• Check what TOC value would mean the leg can is essentially even with the bottom of the hull (minimum exposure). • Compare how much leg is exposed for each option and ask: which setting would most likely reduce hydrodynamic and bending loads during normal ocean tow with moderate winds? • Verify from jack-up operating or stability manuals what the typical leg position for ocean transit is when not expecting extreme storms.
