Effect of ice drift angle on a mooring hawser
The effect of ice drift angle on a mooring hawser was investigated in a series of model tests, with a tanker moored to an off-loading terminal in moving pack ice. The experiments measured the tension in the mooring system as the ice drift direction changed. Three sizes of pack ice were investigated;...
