🔍 Key Concepts

• Elevating limits for jack-up rigs based on roll angle and roll period • How roll period relates to sea state and wave length in coastal waters • Using operator/USCG elevating guidelines tables to match conditions to maximum depth

💭 Think About

• Given a very small single-amplitude roll angle (2°), how does the relatively long roll period (10 seconds) affect the loads on the legs during elevating? • When you look at the elevating guidance tables or curves, what trend do you see between roll period and maximum allowable water depth? • Compare each answer choice with what would be a typical operating water depth range for a coastal jack-up under mild motion—do the extremes (very shallow or very deep) make sense with a 10‑second roll period?

✅ Before You Answer

• Check the MODU/jack-up elevating criteria table that uses roll angle and roll period to find the corresponding max depth • Confirm whether increasing roll period (with small roll angle) allows greater or smaller water depth while elevating • Eliminate any depth options that are clearly outside the normal elevating range for a coastal jack-up under mild roll conditions
