A method for manufacturing a flexible composite belt or cable, in the method, one or more parallel reinforced plastic profiles (11) are manufactured by pultrusion, continuous lamination or other continuous method. After surface treatment, the reinforced plastic profiles (11) are guided at a short distance from one another to coating treatment, which is carried out by extrusion or lamination or pultrusion. In the coating treatment, the reinforced plastic profiles are enveloped with a coating material (12) improving wear resistance which joins the reinforced plastic profiles (11) together and forms the coating of a finished belt or cable (10). Finally, the finished belt or cable (10) is wound on a reel.

A mooring member comprises a rope configured for extending between a vessel floating in a body of water and an anchoring device. The mooring member comprises a plurality of functional elements, wherein a first functional element is wound onto at least a portion of the rope, a second functional element is wound onto the first functional element, and so on, until an outermost functional element is wound onto a second-to-outermost functional element. The functional elements are wound in a helical configuration, and are configured to provide at least one of the following functions: damage protection, buoyancy, optical detection, sonar detection, stiffness control, and anti-fouling.

The present invention relates to a high-strength fibre rope for hoisting equipment like cranes having a rope core (11) comprising high-strength synthetic fibres or strands (4) as well as a sheathing (2) surrounding the rope core (11) and indicating wear, wherein the sheathing (2) has at least a sheath layer, in which the synthetic fibres having different wear resistance and/or tensile strength and/or bending fatigue are interwoven with each other.
