SK78-Siri® S12 Covered are unique High-Performance ropes with excellent properties that meet the requirements of the most demanding applications. They consist of a 12strand load bearing core made by SK78 fibers. This rope construction is lightweight, firm, round and torque free.
SK78-Siri S12® Covered ropes are 8 times stronger than steel ropes and 3 times stronger than polyester (on a weight by weight comparison).
The protective jacket offers very good abrasion resistance and gripping properties when used on winches, capstans, and other types of hardware. Also, it provides extra protection against UV sunlight and environmental degradation. The jacket is non-load bearing and repairable with the use of repair kit.
Developed in-house by Katradis, the special Linear Structural Preformation upgrade the SK78 fiber to a level of superior performance. The application of NIKA-PU coating increases the abrasion resistance of the rope and provides higher operational efficiency.
Compared to wire ropes, SK78-Siri® S12 Covered ropes offer the following benefits:
SK78-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.
