In the event the motion of the DEEP DRILLER is such that critical motion limits are exceeded, you should _______________.
AI Explanation
The correct answer is B) place the unit at 45 foot draft.
When the motion of the DEEP DRILLER exceeds critical motion limits, the proper action is to place the unit at a 45 foot draft. This is because a 45 foot draft provides the most stable configuration for the unit, reducing the risk of exceeding motion limits and ensuring the safety of the operation.
The other answer choices are not correct. Shifting loads to increase KG (A) may not be enough to address the critical motion issues. Placing the unit in standby (C) or at a 65 foot draft (D) would not provide the necessary stability to mitigate the excessive motion.
