Abstract: A load equalizing system for a jack-up leg on a mobile off-shore drilling platform barge, wherein the leg has a plurality of rigidly interconnected generally parallel chords. Each of the chords is connected to the barge by a rack and pinion type jack assembly arranged for raising and lowering the leg relative to the platform and wherein lateral deflection of the leg by wave action or the like causes the chords to move vertically unequally relative to the barge. The improvement comprises a pair of hydraulic cylinder assemblies mounted between each of the jack assemblies and the barge, with the working axes thereof generally parallel with the longitudinal axis of the leg. Each cylinder assembly has a cylinder piston mounted therein and a piston rod connected to the piston and extending longitudinally therefrom. Each of the hydraulic cylinder assemblies has one end connected to the barge and the other end arranged for vertical bearing against the top of one of the jack assemblies.
