The application describes an offshore support structure for drilling rigs and the like. It includes a column structure which stands on the sea bed. The structure is in at least two sections which are relatively tiltable from an initial position in a plane, or planes, which is, or are, transverse to the column axis by the sections being located one relative to the other by a joint means. The joint means define circumferentially arranged tilting axes about which the sections are relatively tiltable. The structure further includes damping means arranged to control the rate of return of the sections to the initial position from a relatively tilted position. The structure may also include yieldable tensioning means urging the sections axially together and resisting the relative tilting. |
