<p>The present invention relates to a control of buoyancy for attachment to large structures being lower, lifted, positioned and transported on the ocean. The present invention relates to controlling the depth and motion of buoyant force underwater. The invention generally applies to offshore floating structures used in the exploration and production of offshore minerals, such as semi-submersible vessels, tension leg platform and spur type platforms, more particularly to offshore floating structures having vertically spaced buoyancy capsule enclosed within an open cross-braced jacket framework or truss support structure including large floating offshore windmills</p> |
