This paper describes the mechanics of what happens within a fiber rope when it is bent around a curved surface under tension. It explains how bending the rope causes: * motion between strand and yarns within the rope * abrasion within the rope struct

A passing ship induces surge and sway forces and yaw moments on moored ships. Breakouts of moored ships can result in personnel injuries and deaths, ship and shore facility damage, and pollution. In a confined channel, the passing-ship phenomenon inv

Rope failure due to axial compression fatigue was found in two recent rope investigations. One of these was an HMPE mooring line on a gas carrier and the other was a nylon SPM hawser. In both incidents, the unusual rope design, with very long rope an

This paper is a survey review of the development of synthetic fiber ropes during the past approximately 75 years. It is partially based on discussions at a recent International Rope Technology Workshop and on the authors' recollections. It is also ba

In recent years several European rope testing laboratories either downsized or closed. But the demand for rope testing has increased, particularly for application specific testing which models service life conditions of ropes, chains and cables. Tens

This paper discusses recent advances in understanding how the length of a fiber rope changes under various tension conditions and histories. The change-in-length characteristics of polyester rope can be completely represented by six properties: origi

Large vessels such as tankers, LNG gas carriers and container ships have traditionally used steel wire ropes for mooring. These ropes are heavy, rust if not properly maintained and also suffer broken wires which make them difficult and hazardous to h

This paper describes a new method and a set of equations for calculating the force-deflection characteristics of the catenary anchor leg. The traditional catenary equations reference horizontal deflection of the catenary top to the catenary generatio
