Manufactured for the demands of the shipping industry, NIKA-Siri® S12 COVERED RSB ropes combine high strength and increased safety in mooring operations of commercial vessels such as tankers, LNG, LPG vessels, Bulk carriers etc. The human-centered design of the ropes is the key characteristic of the NIKA-Siri® S12 COVERED RSB ropes, while maintaining the high performance and very long service lifetime. 

APPLICATIONS: MOORING / TOW LINES / STS OPERATIONS (to be used with synthetic tails) / ANCHORING / OFFSHORE

The protective jacket offers very good abrasion resistance and gripping properties when used on winches, capstans, and other types of hardware.

Also the jacket provides extra protection against abrasion, UV sunlight and environmental degradation. The jacket is non-load bearing and repairable with the use of repair kit.

The 12strand core is treated with NikaThane coating and the unique Linear Structural Preformation (LSP) process enhance the fiber’s superior characteristics and improve drastically the structural stability and the strength efficiency of the rope. Also, the NikaThane coating improves the core-jacket interaction, minimizing the jacket slack during operation.

NIKA-Siri® S12 COVERED RSB ropes are 7-8 times stronger than steel ropes and 3 times stronger than polyester (on a weight by weight comparison). When compared to wire ropes, NIKA-Siri® S12 COVERED RSB ropes are stronger (for the same weight), lighter (making them easy and fast to handle), safer to use, and cost-saving (minimum maintenance needs, no greases, faster operating times).

NIKA-Siri® S12 COVERED RSB ropes are an excellent wire-rope alternative and some of the reasons are the following:

NIKA-Siri® S12 COVERED RSB comply with OCIMF’s latest regulations & recommendations for the safe mooring of the tanker-LPG-LNG and bulker vessels.

Force – Elongation properties

The two-step partition of the rope is attributed to the RSB member that exhibits higher elongation and restraints the snap-back effect when the rope is stretched to break.
