Question 3571 Deck General

The correct answer is B) 18-36 times the diameter of the wire rope. The recommended minimum diameter of the fairlead sheave in a wire rope mooring system is 18-36 times the diameter of the wire rope. This is based on industry standards and guidelines to ensure proper bending of the wire rope over the sheave without excessive wear or fatigue. A sheave that is too small can cause the wire rope to bend at a tighter radius, leading to accelerated wear and potential failure. The other options are incorrect as they fall outside the recommended range.
