Currently, breasting dolphins of deepwater terminals are designed so as ship's berthingenergy shall be absorbed mainly by fenders. As for a singel pile structure (SPS) whichconsists of high-tensile steel, ship's berthing energy shall be absorbed mainly by piles.Major subjects to be cleared for design ofSPS are the lateral load-deflection characteristicsof piles against large deformation, estimatation of residual deformation underrepeated loads and evaluation the safety for fatigue. In this report, both residual deformationand cumulative fatigue damage ratio within a lifetime are computed with considerationof ship's berthing and mooring forces. The lateral load-deflection characteristicsof SPS against large lateral repeated loads which are obtained from the field tests andmodel experiments are taken into consideration in this study.
