NIKA-Siri® S-12 DB P-Cover Rope

NIKA-Siri® S-12 DB P-COVER ropes are High Modulus / High Performance ropes consisting of a 12strand load bearing core and a protective braided jacket. The load bearing 12 strand core is produced using the highest quality UHMWPE fibers and the non-load bearing jacket is made of high tenacity Polyester fibers. This rope construction is firm, round and torque free.

The 12strand core is treated with NikaThane-J coating and the unique heat-setting process enhance the fiber's superior characteristics. NIKA-Siri® S-12 DB P-COVER ropes are 7-8 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) – Anchoring – Tow Lines (to be used with synthetic tails) – STS operations

The application of NikaThane-J coating and the heat-setting process 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. The Polyester jacket protects the High Modulus load bearing core against abrasion and UV & environmental degradation and thus prolongs its service life. For the jacket repair, a standard repair kit is available upon request.

LR Type Approval Certification

When compared to wire ropes, NIKA-Siri® S-12 DB P-COVER 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 P-COVER ropes are an excellent wire-rope alternative and some of the reasons are the following:

  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 DB P-COVER 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.
