Question 3468 Deck General

The correct answer is C) hung off. 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, the drill string is typically "hung off" to secure it in place. This means the drill string is suspended or supported by the rig's equipment, such as the drill floor, to prevent it from being lost or damaged in the heavy weather. The other options are incorrect because: A) supporting the drill string with tensioners would not be appropriate in extremely heavy weather, B) placing the drill string in the setback area would not secure it sufficiently, and D) the lower marine riser package is not designed to support the full weight of the drill string in this situation.
