Question 1 of 27070

The element used to keep weight on the bit at a constant value in spite of up-and-down movement of a MODU during floating drilling operations is the heave or drill string __________.

🔍 Key Concepts

• MODU (Mobile Offshore Drilling Unit) motion in heave (up-and-down movement) during floating drilling • How drill string weight on bit is kept nearly constant despite vertical motion • Purpose and function of a heave / drill string compensating system

💭 Think About

• Which device is specifically designed to absorb or counteract vertical motion so that the bit weight stays nearly constant? • Think about what each option usually does in drilling: which one stabilizes direction, which one keeps tension, which one balances or offsets motion? • If the MODU moves up and down with the waves, what mechanism between the rig and drill string would smooth out that motion so the bit doesn’t alternately slam and lift?

✅ Before You Answer

• Match the term that is commonly paired with "heave" or "drill string" in offshore drilling texts and diagrams. • Eliminate the option that mainly describes keeping lateral alignment or directional control rather than vertical load control. • Confirm which device’s main job is to maintain nearly constant bit weight under vertical motion, not just to keep lines tight or support overall tension.
