초록

A precast, modular spar system (10) having a cylindrical open-ended spar of relatively uniform cross section. The spar has a freeboard section (50), a buoyancy section (70), and a ballast section (90). The sections are formed by joining arcuate segments and stacking the sections. A pressurizing system allows for the injection of air into the segments to vary the buoyancy of the modular spar system.

[ We claim:] [1.]1. A precast, modular spar system comprising:a. a cylindrical open-ended spar of relatively uniform cross section throughout its length and having a length such that its upper end extends above the water surface and its bottom end is subject to only minimal excitation forces caused by waves, said spar comprising a freeboard section, a buoyancy section, and a ballast section;b. a plurality of arcuate shaped segments having a middle tangential wall, at least two outer tangential walls, an outer radial wall, an inner radial wall, and a top ...
