Abstract
1457170 Offshore platforms MITSUI SHIPBUILDING & ENG CO Ltd 18 Oct 1974 [25 Oct 1973] 45232/74 Heading E1H A platform 1 is supported on the sea bottom 6 by legs 2 which can be moved relative to the platform by jacks 3, and each comprises a hollow foot unit 7, e.g. of annular configuration, whose upward movement is limited by a stop 4. When the platform is to be moved, it is lowered to float on the surface 5, the legs are raised, and the foot unit is blown to cause it to lift until it contacts the stop. The foot unit also includes a member 8 which surrounds the member 7. In Figs. 7-9, not shown, an annular foot 7 is divided into four sectors (A) joined together so as to be relatively movable. In Figs. 10 and 11, not shown, a hollow annular member (4') is secured to each leg, and two hollow annular members are loosely disposed beneath it.
