Spectra-Siri® S12 COVERED are High Modulus / High-Performance ropes with long-term fatigue life properties and outstanding quality performance ideal for the critical operations of the shipping industry. They consist of a 12-strand load-bearing core (Spectra® fibers) and a protective braided jacket. This rope construction is firm, round, and torque-free.

APPLICATIONS: Mooring (to be used with Synthetic tails), Anchoring, Tow Lines (to be used with synthetic tails), STS operations, OFFSHORE YACHTING

Spectra-Siri® S12 COVERED ropes combine the excellent properties of Honeywell’s Spectra® fibers and an insuperable manufacturing process. The use of the special NikaThane coating application on the Spectra® fibers and the superior in-house Linear Structural Preformation (LSP) process provides a high-quality robust rope construction with higher strength efficiency and excellent abrasion resistance. Spectra-Siri® S12 COVERED ropes exhibit excellent resistance to UV sunlight and weathering degradation and thus an extended service life (more than 7 years).

Spectra-Siri® S12 COVERED ropes are an excellent wire-rope alternative and offer several benefits:

Spectra-Siri® S12 COVERED ropes are produced according to ISO 10325-2018 and they comply with OCIMF’s latest regulations & recommendations for the safe mooring of the tanker-LNG-LPG vessels.
