Abstract
A semi-submersible vessel 10 adapted to resist heave motion that includes a plurality of support columns 16, each of which has an upper end 19 and a lower end 23. A deck 39 is interconnected between the plurality of support columns 16 at locations upon the columns 16 proximate the upper ends 19 thereof. The deck 39 is a box-shaped structure. A ring-pontoon 43 is connected to the plurality of support columns 16 at locations proximate the lower ends 23 of each of the columns 16. Each support column 16 has a longitudinal axis 29 that is inclined upwardly and inwardly from the ring- pontoon 43 to the deck 39 and the longitudinal axis is oriented substantially radially from a center point 13 of the vessel 10. An angle of columnar inclination of the support columns 16 approaches at least five degrees from vertical. The ring-pontoon 43 is rectangular-shaped, and in one variation, is substantially square- shaped and has corner pontoon portions 49 interconnected by elongate pontoon portions 56. The square-shaped ring- pontoon has a centerline 73 intersecting center points 79 of vertically taken cross-sections 76 of the square-shaped pontoon 43. The elongate pontoon portions 56 comprise four box-shaped structures 59, each of which has a substantially four-sided vertically taken cross-sectional configuration.
