ABSTRACT:
A platform is arranged on one or more separate frameworks. Each of the frameworks is provided with a plurality of downwardly extending hollow legs. Each of the legs has a lower end and its interior is accessible from the platform at its upper end. A plurality of ballastable floats together at least furnish a part of the buoyancy required to maintain the framework structure afloat preliminary to its anchoring on the ocean bottom; each of the floats is mounted at one of the lower ends of the legs and has a bottom wall and a deformable skirt surrounding the bottom wall and depending downwardly beyond the same. A spider-like unit is provided at each of the floats and adapted to discharge pressure medium against the ocean bottom beneath the float when the latter is proximal to or rests upon the ocean bottom. The interior of each leg is connectable with the interior of the associated float and with the space beneath the float so that ballasting material, such as split rock or the like, can be pored through the leg onto the ocean bottom beneath the float, and also ultimately fill up the float and possibly also the leg; this material can be supplied from the upper platform.
