70% to pass

Using high working tensions in the mooring system reduces the _______________.

A hook load at drilling depths over 10,000 feet
B allowable deck load at operating draft
C margin between working tension and breaking strength
D possibility of dragging anchors
AI Explanation

The correct answer is C) margin between working tension and breaking strength. Using high working tensions in the mooring system reduces the margin between the working tension and the breaking strength of the mooring lines. This decreases the safety factor and increases the risk of the mooring system failing under high loads. The other answer choices are incorrect because they do not directly relate to the effect of high working tensions on the mooring system.
