CHEMCO Exit Exam • Set 9 Question 27 of 30

How to prevent failure of the mooring and other components in the mooring system during large swell conditions?

✓

Direct Answer

Option B: By attaching fibre tails on the ends in the mooring ropes

Attaching fibre tails to the ends of mooring ropes allows for controlled energy absorption. These tails have higher elasticity than wire ropes, cushioning the impact during large swells and preventing shock loads from reaching the main mooring lines or winch brakes, thereby protecting the system.
