Strong yet lightweight ropes made with Dyneema® XBO Technology not only outperform other synthetic ropes on bending performance, they also match or even outperform the bending performance of specialty steel wire rope. This makes ropes with Dyneema® XBO Technology ideal for applications where superior bending performance is required.
With the increasing need to reduce the total costs of ownership, systems that depend on steel wire rope have reached their limits. Use ropes with Dyneema® XBO Technology to:
The potential for using ropes with Dyneema® is supported by the findings of the SIRIUS (Safe Installation with Ropes In Ultradeep Sea) JIP testing program run by DNV, Samson Rope, Technip, Subsea7, and Dyneema. This JIP explored the bend fatigue performance of large – over 100 mm diameter – fiber ropes made with Dyneema® on small diameter sheaves. The results showed a slightly better fatigue life for the engineered fiber ropes versus traditional steel wire rope. This indicates that large diameter fiber ropes on sheaves can be used in subsea deployment systems containing active heave compensation.
Dyneema® XBO Technology is a special coating that is only available in combination with Dyneema® fiber.
Ropes with Dyneema® XBO Technology have the same bending performance as specialty steel wire rope. Dyneema® XBO Technology outperforms all other synthetic fibers and has been specifically developed to deliver superior bending performance.
Dyneema® XBO Technology works perfectly with Dyneema® DM20 fiber. The resulting fiber - Dyneema® DM20 XBO - is ideal for designing high strength lightweight synthetic ropes.
Rope with Dyneema® DM20 XBO can run for long periods at maximum payload, even at significantly elevated core temperatures. This is typically seen during Active Heave Compensation mode at maximum payload, with cycle times down to 8 seconds.
Dyneema is experienced in certifying new applications using Dyneema® DM20 XBO to DNV standards.
