← HistoryWhich outcome results when using hemp ropes as mooring lines attached to a stationary pier supporting 15th century Basque galleons?
A)Increased risk of chemical degradation
B)Rope fatigue from cyclic loading✓
C)Reduced frictional wear over bollards
D)Decreased risk of marine organism damage
💡 Explanation
Cyclic loading on fibre ropes causes rope fatigue, because repeated loading weakens the rope fibres over time through the mechanism of material creep and micro-fissure growth. Therefore, mooring failure likelihood is higher, rather than chemical or biological degradation, which act through different, slower processes.
