Extreme Value Estimation of Mooring Loads Based on Station-Keeping Trials in Ice
he purpose of this work is to perform an extreme value estimation of the mooring loads associated with station-keeping of a ship operating in ice. In general, the design of mooring lines is based on estimation of the extreme loading caused by environmental conditions within the relevant area. In Mar...
