| Abstract: | Cables play an inportant role in ship operations, whether in anchoring, in docking, in towing, or in passing through locks. The frequent casualties that result from cable failure attest to the need for a better understanding of cable dynamics. this paper explains analytical techniques that can be used to assess the adequacy of cables of all types. The classical methods for treating static conditions are reviews. Then dynamic conditions are analyzed in recognition of transient loads applied to cables (e.g. the surging of a ship at anchor). Water resistance and cable elasticity are also recognized. The paper concludes with a numerical example showing how the foregoing principles can be applied to a typical situation of a ship at anchor. |
