In the event the motion of the DEEP DRILLER is such that critical motion limits are exceeded, you should __________.

Question 1 of 27070

In the event the motion of the DEEP DRILLER is such that critical motion limits are exceeded, you should __________.

🔍 Key Concepts

• Critical motion limits on a mobile offshore drilling unit (MODU) like DEEP DRILLER • How draft (45 ft vs 65 ft) affects stability and motions on a semi-submersible or similar unit • Effect of KG (height of the center of gravity) on stability and motion response

💭 Think About

• Which action would most directly and immediately reduce risk to personnel, equipment, and well operations when motions become excessive? • How does changing draft on a unit like DEEP DRILLER generally affect its heave, roll, and pitch motions in heavy weather? • Would increasing KG make the unit’s motions gentler or more severe, and why?

✅ Before You Answer

• Verify whether increasing KG improves or worsens stability and motion characteristics on a MODU • Consider which draft (45 ft vs 65 ft) would put more of the hull deeper in water and how that affects motions • Identify which option corresponds to placing the unit in a safer operating condition when motion limits have already been exceeded

Question 1 of 27070

In the event the motion of the DEEP DRILLER is such that critical motion limits are exceeded, you should __________.

place the unit at 65-foot draft

shift loads to increase KG

place the unit at 45-foot draft

place the unit in standby
