Abstract

In a working platform or the like to be placed on the bottom of a body of water subject to intense motion, e.g. the sea bed, comprising (a) a body which during one phase of use of the platform interacts with the moving water and (b) a supporting base which during the same phase interacts with the bottom, the improvement whereby (c) the body and the supporting base are constructed to be movable in such a way relative to each other than the external forces exerted by the interactions on the platform, in so far as a pre-determined value is exceeded, are transmitted by the support base to the body and if required also by the body to the support base, via a medium moving under the influence of these forces, which in this motion experiences a resistance such that almost all or a major part of the kinetic energy is converted to heat. More esp. the body is a platform with buoyancy and provided with legs each of which is moveably connected to a foot suitably for placing on the bottom of the body of water, the legs and associated feet being mutually displaceable in the axial direction of the legs. Provides efficient shock absorption for the platform particularly during the phase of lowering the legs to the seabed, and when the platform assembly is subject to intense wave motion, which could cause the feet to strike the bottom with great force.
