Synthetic fiber ropes are often used in offshore moorings instead of steel and have undergone a rapid testing and development phase over the last five years.

A primary advantage of Synthetics is their lightweight. Lightweight lines are easier to handle and reduce topside weight.

 

Another advantage of Synthetics compared to steel is the very large number of synthetics with a wide range of material properties. Due to this fact, compared to steel it is easier to design a synthetic fiber rope that will match the mooring requirements.

 

Synthetic ropes can be used as a lightweight insert in a catenary mooring. However, their real potential lies in taut moorings where ropes combining low weight and low elastic modulus with good durability characteristics.

 

The main disadvantage of these materials is that they are easy to damage. Being less tough than steel wire rope, synthetic rope shows the damage it receives.
