Abstract

The present invention is a spar platform (10) having a deck (12) supported by buoyant tank assembly (22) having a buoyant chamber outside wall (18) and a buoyant chamber inside wall (20) which defines a vertically extending open moon pool (26). A plurality of buoyant chamber side walls connect the buoyant chamber inside and outside walls and defining a plurality of vertical slots (28). A counterweight and a counterweight spacing structure depend from the buoyant tank assembly.
