NIKA-Siri® X12 ropes are high Modulus / high-performance UHMWPE 12-strand ropes, where each strand is a 12-strand UHMWPE rope over-braided with High Tenacity Polyester sheath, resulting in a robust rope structure.
The specially engineered structure of NIKA-Siri® X12 ropes gives them very high abrasion durability. This unique structure protects against both external and internal abrasion. Each strand is coated with NikaThane-J coating and undergoes a fine Linear Structural Preformation (LSP) process that enhances the rope strand breaking strength.
APPLICATIONS: MOORING / TOW LINES / STS OPERATIONS (to be used with synthetic tails) / ANCHORING / OFFSHORE
NIKA-Siri® X12 ropes are 7 times stronger than steel ropes and 3 times stronger than polyester on a weight by weight comparison. When compared to wire ropes, NIKA-Siri® X12 ropes are stronger on a weight by weight basis, lighter and easier to handle, safer to use with reduced recoiling upon breaking. If floating properties are required then instead of Polyester, the sheath can be made using UHMWPE fibers that enhance also the abrasion resistance even more.
NIKA-Siri® X12 ropes have been field tested in tugboat operations, a highly demanding application, with exceptional results.
NIKA-Siri® X12 ropes are an excellent wire-rope alternative and some of the reasons are the following:
