Procedure to calculate Fender ReactionFirst calculate Normal and Abnormal Berthing force using design sheet.Select fender for Abnormal Berthing Energy. (u will get berthing reaction)But we need what will be same fender reaction for Normal berthing caseFor that we have to take the ratio between Normal Berthing Energy/Abnormal Berthing energyfor example 177/310 *100 = 57%98% of the abnormal berthing conditioni.e if for abnormal berthing condition for selected fender reaction developed is 665 kN. then for normal berthing condition its = 0.98*665=651.7

Here energy of normal berthing 57% lesser than abnormal but reaction developed in the fender57%
