Berthing Load on Fenders
Total design berthing energy shall be assumed to be trasferred to contact fenders.
Fender load for that level of berthing energy shall be calculated from fender charecteristic graph
Right hand axis in above curve reflects energy absorbed and left side vertical axis reflects reaction
produced corresponding to tat absorbed energy.
