Wire rope and its benefits

Wire rope can also be constructed of only individual wires tightly spaced and wound without stranding, known as spiral strand. This construction commonly uses a sheath for protection since it is much more susceptible to damage. To eliminate torque, the rope construction (spiral strand, half locked and full locked coils) uses layers of wires (or bundles of wires) wound in opposing directions to obtain the torque balanced characteristics.

Wire rope has a lower fatigue life and is more sensitive to damage and corrosion compared to chain. As per DNV-OS-E304, wire rope segments in mooring lines are to be protected against corrosion attacks throughout the design life, either through coating of the strands or sheathing of the rope. Regular inspections are recommended throughout the design life to ensure the protection is intact and corrosion is within acceptable limits.

Termination connections also are available in various sizes to accommodate any size of mooring components. All wire ropes and components are certified and approved for use offshore by facilities managers. InterMoor, a brand in Acteon’s Engineering, Moorings and Foundations division, offers varying sizes and configurations for wire rope. All wire ropes have an independent wire rope core (IWRC) of the highest quality grade and meet all requirements necessary to perform in the offshore industry.
