This paper presents the comparison between the British and the PIANC standard on the calculation of berthing energies,and the fender design energies are compared with that of the Chinese code.In addition,the eccentricity coefficient is further studied.The conclusions are as follows:1)The parameters such as eccentricity coefficient,hydrodynamic mass coefficient and abnormal berthing energy coefficient are different in the calculation of berthing energy in British standard and PIANC code.2)The design value of berthing energy container vessels in British standard is mostly less than that of PIANC,while that of oil tankers is greater than that of PIANC.3)When the tanker berths at the third point,the impact energy is about 1.3 times of that at the fourth point.4)The eccentricity coefficient CE value is affected by the deviation of manifold of oil tanker and gas carrier,which decreases with the increase of tonnage,and the influence degree is 12%~29%.
