🔍 Key Concepts

• Jack-up rig towing procedures in heavy weather and why leg position matters • How lowering the legs changes the TOC (tip-of-can) depth relative to the water surface and hull • Typical storm tow practice: increasing leg immersion to improve stability and structural safety

💭 Think About

• Think about what happens to the rig’s center of gravity and stability when the legs are lowered during a storm tow. Should the TOC value become much deeper, slightly deeper, or stay almost the same? • Compare how much each option increases the TOC from 12.38 feet. Which increase seems more consistent with a deliberate heavy-weather configuration rather than a small trim change? • Consider realistic clearances: in open-ocean tow, would you expect the legs to be just barely in the water or significantly immersed for storm conditions?

✅ Before You Answer

• Calculate the difference between 12.38 feet and each answer choice to see how much extra leg immersion each option represents. • Ask whether the chosen TOC would still keep the legs clear of the seabed in typical ocean depths – eliminate any choice that would be unrealistic for an offshore tow route. • Verify what a storm tow condition normally aims to achieve: a substantial change in stability and strength, not just a minor adjustment.
