We developed a new type marine fender called as "Hybrid-fender" which was consisted of a first-fender, a guide pipe and an oil damper. In order to investigate the property, we conducted several ship berthing tests in prototype. Then we confirmed that the fender had several different unique properties compared with the existing marine fenders. On the other hand, several fender designs which consider not only the ship-berthing energy but also moored ship motions have been done because problems on large and long-period moored ship motions in harbor basins have been revealed in many ports and harbors around the world. In the fender design, a numerical simulation method on moored ship motions has to be used properly. In this paper, we try to model the property of hybrid-fender in the numerical simulation of ship motions and verify the modeling by reproducing the ship-berthing test.
