Construction types used for mooring solutions

Core-dependent Twin

In a core-dependent Twin rope construction, the interior core bears the entire load. The role of the cover is to protect the core from abrasion and other potential damage.

Load-sharing Twin

In a double braid rope, the core and cover share the load equally, even though applications may vary considerably.

One

With a round braid the alone-standing load-bearing braid determines the technical properties: it functions without a core – or without a cover, depending on your view of things…

Square

In a square plait rope, eight strands are interwoven to form a roughly square-shaped cross-section. It is very robust and has good grip, while simultaneously being relatively economic and easy to splice.
