Abstract

A shock absorbing column assembly (10) is provided for attachment to a structural member (12) of an offshore platform. The assembly (10) utilizes a series of shock absorbing elements which cooperate together to absorb shock exerted on the assembly by adjacent vessels. Two shock cells (34) and (36) support the vertical column member (30) in a position spaced away from member (12). Column member (30) is connected to the extending arm of the shock cell by shock absorbing connectors (52) and (54). An outer protector (90) is resiliently connected around the outside of the column (50).
