Safely replace large-diameter steel wire rope
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 DSM. 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.
