In this study, I calculated and evaluated the regression equations of displacement tonnage of ships by carrying out the statistical analysis using the latest ship specification data. In the calculation, I employed full load displacement tonnage and ballasted displacement tonnage for 10 kinds of ships: cargo ship, container ship, oil tanker, roll-on/roll-off (RORO) ship, pure car carrier (PCC), LPG carrier, LNG carrier, passenger ship, short-to-medium distance ferry and long distance ferry. As a result of this study, I proposed that the regression equations of displacement tonnage of ships for the coverage rate of 75% should be used for calculating the berthing energy of a ship when designing fenders.

Key Words: displacement tonnage of ship, regression equation, coverage rate, statistical analysis, fender design
