ABSTRACT:
The present invention relates to a method and apparatus for supporting a body element. The apparatus includes at least one support device with at least one closed or controlled-release chamber, a filling device and an emptying means device for filling said chamber with a filling fluid and emptying the fluid from the chamber, and a distance-measurement device for measuring the distance between a top face and a bottom face of the chamber. The apparatus further includes a reaction-measurement device for measuring the reaction of the support device relative to the morphological data of the body element to be supported, and a control system including a combination device for combining the measurement of the penetration distance d provided by the distance-measurement device and the measurement of the reaction provided by the reaction-measurement device. This combination is advantageously constituted by summing the two obtained measurements. The invention makes it possible to support the element to be supported substantially in a position of equilibrium corresponding substantially to a predetermined float line.
