SIMPLIFIED METHODS FOR CALCULATION OF DAMPING COEFFICIENTS USING RECORDS OF FREE NONLINEAR ROLLING WITH LARGE AMPLITUDE DECAY

Large amplitude decay is the constant phenomenon of the free nonlinear rolling of the ships with bilge keels, in the case of deck submergence in model rolling tests, etc. Several different methods can be used to interpret the records of model rolling tests. Some of them are inadequately precise for the rolling with large amplitude decay, some are quite accurate but very complicated. The methods described here enable one to make simple and accurate calculations of damping coefficients with large and small rolling amplitude decay.
