ΝΙΚΑ-Siri® S-12 DB Rope
NIKA-Siri® S-12 DB are High Modulus / High Performance ropes with excellent properties, ideal for the demanding shipping industry. They consist of a 12strand load bearing core (highest quality UHMWPE fibers) and a protective braided jacket. This rope construction is firm, round and torque free.
APPLICATIONS: MOORING / TOW LINES / STS OPERATIONS (to be used with synthetic tails) / ANCHORING / OFFSHORE / YACHTING
There are three options for the jacket:
a. 100% Polyester jacket: A reliable protective jacket that offers very good abrasion resistance and gripping properties when used on winches, capstans and other types of hardware.
b. Mixed jacket (UHMWPE/PES): A special blend of UHMWPE and polyester fibers form a highly abrasion protective jacket, that combines the gripping efficiency of Polyester and the ultra-high abrasion resistance of UHMWPE fibers.
c. UHMWPE jacket: A High Modulus jacket that provides maximum abrasion resistance prolonging significantly the rope’s service life.
These special jackets provide extra protection against abrasion, UV sunlight and environmental degradation. The jackets are repairable with the use of repair kit.
The 12strand core is treated with NikaThane-J coating and the unique heat-setting processes enhance the fiber’s superior characteristics and improve drastically the structural stability and the strength efficiency of the rope. Also, NikaThane-J coating improves the core-jacket interaction, minimizing the jacket slack during operation.
NIKA-Siri® S-12 DB 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® S-12 DB 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 DB ropes are an excellent wire-rope alternative and some of the reasons are the following:
- Most cost-effective ropes to purchase due to lower labor requirements in operations and decreased mooring & towing operating times
- Safer and easier to use due to their high strength and low weight.
- 2-3 times longer service life
- Negligible maintenance costs
NIKA-SIRI® S-12 DB ropes are produced according to ISO 10325-2009 and they comply with OCIMF’s latest regulations & recommendations for the safe mooring of the tanker-LPG-LNG vessels.
