In many cases, chain is coupled with fibre rope, sections of chain on a mooring line provide weight and wear resistance where it is most needed, while fibre sections keep weight down and improve the manageability of the system.

In a deepsea aquaculture single point mooring system, PP&PET rope acting as down mooring line, it has floating characteristic, polester double braide rope acting as up mooring line, it has sinking characteristic, the goal of the mooring is to create an inverse catenary.
The diameter of rope our factory can manufacture is from 2mm to 300mm. Structures are including 3 strands, 4 strands, 6 strands, 8 strands, 12 strands, 16 strands, 24 strands (double braided), 32 strands (double braided), 36 strands (double braided), 48 strands (double braided) and multi structure braided rope. The ropes can apply to ocean engineering, ocean shipping, shipbuilding, port towing, aquaculture mooring, sea farming and etc. The main products are Ultra High Molecular Weight Polyethylene (Dyneema®), Power-mixed Rope (PET+PP), Polyester (PET), Polyamide(Nylon/PA), Polypropylene (PP), Polyethylene (PE) and etc. Welcome to contact us: sales@qdwaysail.com
