A 40m X 6m all aluminum bridge to link two offshore unmanned platforms on a Shell Oil development in south east Asia. The bridge has two levels to tie in with the platform levels: the upper level carries heavy wireline equipment rolling loads (2MT) and the lower level carries walkways and piping. The bridge weighs only 20MT and saved approx 30MT by building it in aluminium. Two ‘wings’ of solar panels are attached to the top end of the bridge via aluminium supports.
