SK78-Siri® S12 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® ropes are 8 times stronger than steel ropes and 3 times stronger than polyester (on a weight by weight comparison).
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 ropes offer the following benefits:
SK78-Siri S12® 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.
