The limit switches on a MODUs survival-craft winch system _______________.

A stop the winch in case the craft weighs too much
B limit the ascent rate
C stop the winch just before the craft reaches the final stowage position
D limit the amount of cable on the drum
AI Explanation

The correct answer is C) stop the winch just before the craft reaches the final stowage position. The limit switches on a MODU's (Mobile Offshore Drilling Unit) survival-craft winch system are designed to stop the winch just before the craft reaches its final stowage position. This ensures the craft is gently lowered into its storage location without impacting the structure and potentially causing damage. The limit switches act as a safety mechanism to prevent the craft from being over-lowered. The other options are incorrect because: A) the weight of the survival craft is already accounted for in the winch system design, B) the ascent rate is controlled by the winch system itself, not the limit switches, and D) the limit switches do not directly control the amount of cable on the drum.
