NIKA-Siri® S-12 Rope

NIKA-Siri® S-12 Single Braided ropes are 12 strand High Modulus / High Performance ropes, produced using the highest quality UHMWPE fibers. NIKA-Siri® S-12 SB ropes are treated with NIKAThane-S coating during a unique heat-setting process that enhances the fibers' superior characteristics.

NIKA-Siri® S-12 SB ropes are 8 times stronger than steel ropes and 3 times stronger than polyester (on a weight by weight comparison).

APPLICATIONS:  Mooring (to be used with Synthetic tails) – Tow Lines - STS operations (to be used with Synthetic tails) – Anchoring

The application of NIKAThane-S coating and the heat-setting process improve drastically the structural stability and the strength efficiency of the rope while increasing the rope's coefficient of friction for better gripping performance when used in winches, capstans, chocks, bitts etc.

When compared to wire ropes, NIKA-Siri® S-12 SB ropes are stronger (for the same weight), lighter (making it easy and fast to handle), safer to use and cost-saving (minimum maintenance needs, no greases, faster operating times).

NIKA-Siri® S-12 SB ropes are an excellent wire-rope alternative and some of the reasons are the following:

LR Type Approval Certification
  1. Most cost effective ropes to purchase due to lower labor requirements in operations and decreased mooring & towing operating times
  2. Safer and easier to use due to their high strength and low weight.
  3. 2-3 times longer service life
  4. Negligible maintenance costs

NIKA-Siri® S-12 SB ropes are produced according to ISO 10325-2009 and they comply with OCIMF's latest regulations & recommendations for the safe mooring of the tanker-LNG-LPG vessels.
