1.3 Stopper Check The maximum load applied on 1 ROLL stopper Fws  frs1  40.98  tonne The analysis of the seafastening has been carried out using SAC5.4

1.4 Stopper Check

The maximum load applied on 1 PITCH stopper Fps  fps2  45.533 tonne The analysis of the seafastening has been carried out using SAC5.4
