SK78 Prisma-Siri® S-12 DB Rope
SK78 Prisma-Siri® S-12 DB are unique High-Performance ropes with excellent properties that meet the requirements of the most demanding applications. They consist of a 12strand SK78 Prisma® Shielded load bearing core and a protective braided jacket. This rope construction is firm, round and torque free.
APPLICATIONS: MOORING / TOW LINES / STS OPERATIONS (to be used with synthetic tails) / ANCHORING
There are three options for the jacket:
These special jackets provide extra protection against abrasion, UV sunlight and environmental degradation. The jackets are repairable with the use of repair kit.
The special Prisma® Shield 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, 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 DB 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 DB 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.
