NIKA-Siri® X-12 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 special engineered structure of NIKA-Siri® X-12 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’s breaking strength.
APPLICATIONS: MOORING / TOW LINES / STS OPERATIONS (to be used with synthetic tails) / ANCHORING / OFFSHORE
NIKA-Siri® X-12 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® X-12 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® X-12 ropes have been field tested in tugboat operations, a highly demanding application, with exceptional results.
NIKA-Siri® X-12 ropes are an excellent wire-rope alternative and some of the reasons are the following:
