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:
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.
