ABSTRACT:
A method for deploying a floating platform includes storing buoys on a hull of the platform. Tension devices are mounted to the hull, each being connected by a line to one of the buoys. The operator tows the hull to a ballast down site while the buoys are stored on the hull. While adding ballast to the hull, the operator feeds out the lines from the tension devices at a selected tension. The hull moves downward in the water while the buoys float at the surface to maintain stability during the ballasting. The buoys are detached from the lines after the hull is ballasted to a desired depth.
