Abstract
Abstract A fender assembly to be mounted on the surface of a quay-wall as found in harbors or dockyards comprises two pairs of rubber elements each having a plate like trapezoid shape and a rigid impact receiving plate. The pairs of rubber elements are adapted to be secured on to the surface of the quay-wall so that they form together a frustum of a quadrilateral pyramid widening towards the quay-wall surface. The impact receiving plate is rigidly secured on to the top of the pairs of rubber elements.
