heal.abstract	This paper presents a comparative study on the dynamic analysis of suspended wire and chain mooring lines. This study was initiated by the International Ship and Offshore Structures Congress (ISSC), Committee 12 (Loads) and is briefly described in the 1997 report presented at Trondheim, Norway. The paper provides more complete documentation of the study. A total of 15 contributions were provided giving analytical results based on time or frequency domain methods for a chain mooring line suspended in shallow water and a wire line in somewhat deeper water. Bi-harmonic top end oscillations representing combined wave and drift induced excitation were specified. The mooring line damping results calculated for chain are compared with limited available experimental data, results provided by the participants showing fair agreement despite the complexity of the numerical methods. Predictions of dynamic tension based on time-domain methods are in broad agreement with each other, the estimates of damping showing more scatter. There are wider discrepancies between results based on frequency-domain methods.This paper presents a comparative study on the dynamic analysis of suspended wire and chain mooring lines.
