ABSTRACT:
A load transfer apparatus for jackup barges provides a barge and at least three legs movably attached to the barge with a jacking mechanism associated respectively with each of the legs for vertically moving the legs with respect to the barge. A hydraulic pad is associated with each of the jacking mechanism and is placed between the jacking mechanism and the barge, forming a load transfer and load monitoring interface between the jacking mechanism and the barge. The pad includes preferably a hollow inflatable steel reinforced rubber pad which is pressurized during operation using suitable hydraulic fluid. The apparatus reduces impact load on the platform structure when the legs first touch bottom and might also be used to pre-load the legs using the hydraulic pads instead of ballast. The apparatus can be additionally used to monitor the load carried by each leg and to balance the loads among the legs, as well as to dampen vibrations.
