ABSTRACT:
An oscillating structure for exploration at sea features a column which rests on a heavy base resting on the sea bottom, and which supports a platform above sea level. The column is connected to the base by an articulated joint which allows it to oscillate in all directions under action of swell, the articulated joint comprising two base plates cooperating with the substantially flat and parallel surfaces of the bottom of the column and the upper surface of the base respectively, two supports fixed on each of the plates and parallel one to the other, bearings, formed of two half bearings which can be dismantled, fixed to the ends of the said supports, the bearings of the supports fixed to the same base plate being in alignment, and a cross shaped member, whose branches are located in different planes, extending between the bearings.
