Fender for offshore platform

摘要

A shock absorbing bumper system assembly is provided for attachment to a structural member (12) of an offshore platform. The assembly utilizes a vertical column 34 supported from upper and lower support arms 20 and 22. An outer protector 32 surrounds the column 34 and is mounted on it by a pair of resilient elements 38 and 40 which are positioned in an axially spaced relationship to leave an unsupported length of column. Impacts are absorbed by deformation of the unsupported length of the outer protector 32, and by the annular elastomeric elements 38, 40. There may be further annular or half-annular elastomeric elements between the column 34 and the support arms, and shock cells between the arms and the structure. The protector 32 may be concentrically mounted on the column 34.
