SK78 Prisma-Siri® S-12 Rope
SK78 Prisma-Siri® S-12 is a unique 12 strand High Modulus/High Performance rope made of SK78 fibers. The Prisma® Shield technology enhances the SK78 fiber’s superb characteristics, resulting in a really strong and durable rope, ideal for the most demanding applications in the shipping industry.
SK78 Prisma-Siri® S-12 ropes are 8 times stronger than steel ropes and 3 times stronger than polyester (on a weight by weight comparison).
APPLICATIONS: MOORING / TOW LINES / STS OPERATIONS (to be used with synthetic tails) / ANCHORING / OFFSHORE / AQUACULTURE / FISHING / YACHTING
The special Prisma® Shield technology and the elaborate in-house heat-setting process upgrade the SK78 fibers 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, SK78 Prisma-Siri® S-12 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).
SK78 Prisma-Siri® S-12 ropes are an excellent wire-rope alternative and some of the reasons are the following:
- Most cost-effective ropes to purchase due to lower labor requirements in operations and decreased mooring & towing operating times
- Safer and easier to use due to their high strength and low weight.
- 2-3 times longer service life
- Negligible maintenance costs
SK78 Prisma-Siri® 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.
