🔍 Key Concepts

• Liftboat jacking operations and the importance of keeping the hull clear of the water during leg problems • Risks of applying excessive side load or rotational force to a stuck leg • Basic safety principle: protect the hull, legs, and seabed structure by avoiding sudden or extreme movements

💭 Think About

• Which choices would increase side loads or twisting forces on the stuck leg rather than relieving them? • How does partially supporting the hull on the legs versus fully afloat affect the ability to free a stuck leg safely? • Which option best maintains control and minimizes the risk of structural damage to the legs or hull?

✅ Before You Answer

• Eliminate any option that would twist the vessel around a single fixed leg • Be cautious of any step that would overload the jacking system or leg structure • Consider which action keeps the operation gradual and controlled rather than sudden or extreme
