A semisubmersible drilling rig concept is described. The rig utilizes a large buoyant center caisson and specially shaped lower hulls to improve the vessel's motion characteristics. The center caisson serves as vertical storage for riser joints and one of the units blowout preventer stacks. By use of this buoyant storage area, the vessel's center of gravity is lowered and the upper deck is cleared for extra working space.
