Find out about our expertise in manufacturing of High Performance ropes

Over the past few years, the use of High Modulus ropes in mooring operations of commercial vessels has significantly increased while the operational conditions are getting more and more demanding.

Quality and performance is the core parameter for long-term service life and safe mooring operations and this is where our engineering and manufacturing processes make the difference.

Our Linear Structural Preformation (LSP) process which has been developed by KATRADIS MARINE ROPES INDUSTRY SA with mutual studies along with Chemnitz University, is a key stage in manufacturing our Siri High Performance ropes. Basically, it is a two-step procedure which enhances the mechanical properties of the rope:

• Coating with Polyurethane based material: Each fiber is coated for extra protection against abrasion, which is the most frequent cause of fiber damages during operation.
• Pre-stretching and drying of the whole rope length, providing structural stability and faster adjustments on the working conditions.

Residual strength tests from used ropes in the field have shown excellent results which verify the high quality and long lifetime expectancy of our Siri® High Performance ropes.

Improvement of Yarn-on-Yarn abrasion performance

When abrasion is a service life limiting factor, our special NIKA-Thane Polyurethane based coating improves drastically the performance of the rope and the durability against abrasion. Test results have shown 5 times better durability of coated Siri® fibers when compared to commonly used UHMWPE fibers without coating protection.
