Abstract
A device for the integrated suspension and manipulation of legs supporting a jack-up oil platform having a hull mounted displaceably on the legs by drive mechanisms having at least two opposite units each formed by a motor associated with at least one speed reducer driving an output gear co-operating with opposite racks mounted on at least part of the length of the legs. The opposite units of each drive mechanism are mounted in articulated fashion on a structure supporting them via at least one bearing allowing a determined angular deflection of the units and of each corresponding output gear. The motor and the speed reducer of each opposite unit are housed in a member for absorbing energy, used, in particular, at the moment of the placement of the legs on the sea bed and for limiting the stresses due to the flexure of the legs under the action of swells and the wind.
