  • Patent number: 4169296
    Abstract: A personnel bridge for connecting a stationary offshore working platform 1 to a floating housing platform 2. A first span 3 is vertically pivoted at 5 to the platform 1 on one end, and vertically pivoted at 6 to the outer end of a second span 4 whose inner end is mounted to the platform 2 by a ball joint 8. The outer ends of the spans 3, 4 are also connected through a horizontal pivot axis 7, whereby movements between the platforms 1, 2 in three mutually orthogonal directions may be accommodated. The spans may be supported from a tower 10 by a fixed cable 9 pivotable at one end about an axis 11 aligned with the vertical axis 5, and by a winch controlled cable 12.
