Abstract
A floating spar hull for offshore oil and natural gas exploration and production having a centerwell arrangement wherein a supporting wellbay deck is positioned in the centerwell at a level below the uppermost portion of the spar hull in the centerwell. The wellbay deck is attached to the spar hull by any suitable means such as shear plates such that a space remains between the deck and the spar hull for risers. This allows equipment to be placed below the uppermost deck of the topsides and eliminates or minimizes wind loads on the equipment.
