Abstract

A semi-submersible platform 20 is supported on columns 30, 34, 35, 36 with pontoons 37, 38 extending between an outboard of the columns. Damper plates are provided by flat surfaces 45, 46 either on top of the outboard section of the pontoons or by plates positioned on the columns above the pontoons to provide heave stabilization and motion phase control in relation to the wave action such that when the platform is in the drilling mode the heave phase of the platform is approximately one hundred eighty degrees out of phase with wave action and in the survival mode heave action of the platform is substantially in phase with wave action. <IMAGE>
