In a storm, the leeward lines of a MODU's mooring system will _______________.

A pull the unit in the same direction that the weather is pushing it
B pull the unit in the opposite direction that the weather is pushing it
C affect the unit's draft and inclination as maximum mooring tensions are reached
D tend to keep the unit on its original location over the well head
AI Explanation

The correct answer is A) pull the unit in the same direction that the weather is pushing it. In a storm, the leeward lines (lines on the downwind side) of a MODU's (Mobile Offshore Drilling Unit) mooring system will pull the unit in the same direction that the weather is pushing it. This is because the forces acting on the leeward lines from the wind and waves will be in the same direction, causing the unit to be pulled towards the leeward side. The other options are incorrect because: B) is the opposite of the correct answer, C) refers to the unit's stability rather than the direction of motion, and D) is incorrect as the mooring system will not necessarily keep the unit in its original location during a storm.
