Abstract

Angular stabilization and positioning of a semi-submersible platform is achieved through floating supports whose length is substantially greater than their diameter, closed at their base and vertically oriented with a cylindrical horizontal member on which the swell acts fixed to the base to compensate the angular movement it produces on the vertical supports and to position the platform in relation to the direction of its propagation.
