A fender system including a supporting frame mounted on a stationary structure by energy-absorbing shock mounting members, and the frame carrying annular bumper members stacked one above the other and sized for rotation about a pipe column, the bumper members each having their respective end surfaces stepped at an annular step in such a way that the stepped surfaces of adjacent bumpers mate and interlock, and the bumper members having multiple relief holes extending in from their end surfaces parallel to the axis of the bumper members and tending to impart a degree of asymmetrical distortion to an impacted bumper member causing it to creep around the pipe column on which it is supported; such rotation being aided by friction reducing means on the surfaces of the bumper members.

A fender system for attachment to a stable structure for fending off vessels such as boats and barges being landed thereadjacent; comprising: a. a fender supporting frame attached to said stable structure and including an upright bumper supporting circular cross-section column, said fender supporting frame further including upper and lower mounting members securing said bumper supporting column to the stable structure and the upper and lower members including yieldable shock absorbing members comprising energy absorbing shear mounts having metal plates alternating with layers of molded elastomer bonded thereto; and b. a plurality of similar elastomeric bumpers surrounding said upright column in mutually stacked relationship, each bumper comprising a thick wall resilient cylindrical body having end walls and having an inner diameter which is cylindrical and has an inner periphery sized to loosely receive and freely rotate on said column and each inner periphery having an antifriction layer of material harder than the elastomeric body, and each bumper having an outer diameter which is large as compared with the bumper\s axial length, and the end walls of the bumpers being disposed so that they mate with the end walls of adjacent bumpers in the stack so as to provide a composite outer bumper surface which is substantially smooth and continuous and cylindrical so as to resist separation of the bumpers upon contact by a vessel.
