CABRAL 512® polyester ropes are manufactured from high effi ciency sub-rope cores laid parallel within an outer braided jacket. Each sub-rope is monitored during rope manufacture to ensure all sub-ropes have equal tension and length. Typically, CABRAL 512® ropes include 7 to 18 sub-ropes, each sub-rope being of a long lay length 12 x 1 construction, which gives a 100% torque free rope.

The design of this mooring rope consists of parallel laid yarns to construct the strands of the sub-rope cores which are also laid parallel within an outer braided jacket. Again, each sub-rope is of a long lay length 12 x 1 construction, which gives a 100% torque free rope.

Axial Stiffness
Stiffness is normally divided into two categories: static stiffness and dynamic stiffness. Static stiffness is used to determine the extension of the rope from first order motions and calculate the offset of the vessel. Dynamic stiffness is used to calculate the peak loads in the mooring lines during second order motions of the vessel. CABRAL 512® is the stiffest rope construction currently available in the market for deepwater mooring applications. It requires less constructional extension due to bedding in and lower overall elastic extension resulting in smaller platform offsets and the option to utilise lower pre-tensioning during installation. In order to maximise the efficiency of the mooring system, Lankhorst recommends performing a stiffness test at an early stage. This stiffness test should incorporate static and dynamic loading scenarios and is performed on a sub-rope. Lankhorst can offer this service to our clients, please ask for further details.
