ABSTRACT:
An offshore platform support structure having a column structure including at least two sections, each section being joined to a vertically adjacent section by a plurality of circumferentially arranged joints defining a plurality of hinge axes lying in a plane substantially normal to the vertical axis of the column structure, to permit yielding tilting about any one of the hinge axis in response to excessive lateral forces exerted against the column structure, and the structure further including damping means arranged to control the rate of return of said sections to the initial position from a relatively tilted position.
