Prisma® SK78 S-12 Ropes

PRISMA® SK78 S-12 rope is a unique 12strand High Modulus/High Performance rope made of SK78 fibers. The Prisma® Shield technology enhances the SK78 fiber's superb characteristics and the result is a really strong and durable rope, ideal for the most demanding applications in the shipping industry.

PRISMA® SK78 S-12 ropes are 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 special Prisma® Shielded technology and the elaborate in-house heat-setting process upgrade the SK78 fiber to a level of superior performance. The application of Prisma® coating is performed on the fiber level and protects the SK78 fibers from abrasion and UV radiation. In the end, the whole process guarantees a top quality rope with extra high strength efficiency and excellent abrasion resistance.

When compared to wire ropes, PRISMA® SK78 S-12 ropes are stronger (for the same weight), much lighter (making it easy and fast to handle), safer to use and cost-saving (minimized maintenance needs, no greases, much faster operating times).

LR Type Approval Certification

PRISMA® SK78 S-12 ropes are produced according to ISO 10325-2009 and they comply with OCIMF's latest regulations & recommendations for the safe mooring of the tanker-LNG-LPG vessels.
