Question 1 of 27070

An elevated jack-up weighs 14,000 kips. The drill floor, weighing 700 kips, is skidded 10.0 feet to starboard. The change in TCG is __________.

🔍 Key Concepts

• Transverse shift of center of gravity (TCG) due to moving a weight sideways • Using the moment = weight × distance concept for calculating shift of G • Total displacement vs. weight being moved and how they relate in the formula

💭 Think About

• How does moving a smaller weight on a larger structure affect the combined center of gravity? Will it move more, less, or the same as the distance skidded? • What formula links the moved weight, the distance it is moved, and the resulting change in TCG of the whole jack-up? • After you compute the change in TCG, should it be a large shift (many feet) or a relatively small shift given the total weight?

✅ Before You Answer

• Write and use the standard shift of G formula for transverse movement: change in TCG = (w × d) / W • Make sure units are consistent (all in kips and feet) before plugging into the formula • Confirm the direction of the shift (port or starboard) based on which way the drill floor is moved
