Effect of vessel hydrodynamic mass on the station‐keeping response of a moored offshore vessel

摘要

AbstractAn anchoring system for an offshore vessel must meet certain prescribed requirements controlled by factors such as the environment at site, the operational constraints and the vessel employed. Its adequacy, survival and ability to stay on site must therefore be checked out with proper methods of analysis. Since the inclusion of added mass is generally an important consideration in the dynamic analysis of a moored vessel, the effect of the hydrodynamic mass terms on the station‐keeping response of an offshore construction vessel is investigated in this study from a viewpoint of mooring system desig
