SUSPENSION DEVICE FOR THE SUPPORT LEGS FOR A JACK-UP OIL PLATFORM A B S T R A C T The suspension device for the support legs of a jack-up oil platform comprises a hull mounted to be mova- ble along the legs (2) by a driving mechanism comprising a plurality of output gear pinions (11) cooperating with racks (5) mounted on at least a part of the length of the legs (2). Each of the output gear pinions (11) is driva- ble by an electric motor associated with a speed reducer (16) which is pivotally mounted on a structure (15) which carries them and is connected to the hull (1) by at least one bearing (18, 18b) which allows a given angular move- ment of said speed reducer (16) and each corresponding output gear pinion (11). Each speed reducer (16) of the driving mechanisms (10) cooperates with an energy absorb- ing mechanism (20) comprising at least one torsionally elastically yieldable support element (25, 30, 31, 40, 50) connected to said corresponding speed reducer and afford- ing a progressive absorbtion of the shock in particular at the moment when the legs (2) are placed on the sea bed.
