Abstract
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.
