An improved floating structure suitable for use as a floating drilling platform, production platform or other moored floating structure having a vertical tension mooring system with a plurality of anchors, ballasting and deballasting means, and a plurality of mooring lines connecting each anchor to the floating platform, the anchors having a total buoyancy to support the entire weight of the structure so that in transit a minimum structure is below the water, and to minimize surge or sway having a mooring line pretension to displacement ratio in the range from 0.05 to 0.3, having an anchor weight in the range from 0.10 to 0.45 of the anchor displacement and 0.10 to 0.60 of the platform displacement and an anchor displacement in the range from 1.05 to 1.30 times the platform displacement. |
