Under extremely heavy weather on the DEEP DRILLER, when operating conditions are too severe to permit the drill string from being tripped out of the hole and laid down in the pipe racks, it may be __________.
• Deepwater drilling operations – what is normally done with the drill string when you cannot safely trip it out of the hole • The purpose of a setback area versus tensioners on a floating drilling unit • What it means to hang off a drill string in terms of how the load is transferred and where it is supported
• Ask yourself: In extreme weather, which option leaves the drill string in the safest, most controlled condition without relying too much on motion‑sensitive equipment? • Which choices describe temporary storage on deck, and which describe securing the string through the well / wellhead structure? • Think about where the weight of the drill string ultimately goes in each option – is it into the deck, into motion‑compensated gear, or into the well structure?
• Be clear on the function of drill string tensioners – are they intended as the primary long‑term support in extreme storms? • Recall what the setback is used for and whether the question says you can fully trip the string out of the hole. • Know the definition of hung off on a drilling unit – where is the string secured and how is the load carried in that condition?
