Based on general experience in the industry, compared to spiral strand wire rope, polyester rope is an alternative providing the same capacity of station keeping while presenting the following advantages:
- Lighter weight
- Lower mooring pretension and thus lower pull-in loads
- Lower mooring loads
- Excellent fatigue life, low axial stiffness results lower tension-tension and OPB fatigue in the chain sections
- No corrosion related issues
- Ease of handling during installation
It has been shown that mooring system with polyester rope can deliver satisfactory performance for the spread mooring system.
