The time-domain analysis was effective and … WebIn most conditions the hawser force is small compared to the criterion. In some conditions, fishtailing causes large mooring forces, mainly in ballasted condition. Fig. 16, Fig. 17 show the effect on fishtailing on the maximum hawser force. When the tanker is controlled by the pullback force (), peak loads in the hawser can be avoided. This ...
