CONTINUOUS VERTICAL TUBULAR HANDLING AND HOISTING BUOYANT STRUCTURE
First Claim
1. A continuous vertical tubular handling and hoisting buoyant structure with an axis for making up, breaking out and installing marine objects, the continuous vertical tubular handling and hoisting buoyant structure comprising:
- a. a hull comprising;
(i) a main deck;
(ii) upper neck connected to the main deck;
(iii) an upper frustoconical side section connected to the upper neck;
(iv) an intermediate neck connected to the upper frustoconical side section;
(v) lower frustoconical side section that extends from the intermediate neck;
(vi) a lower neck, extending from the lower frustoconical side section;
(vii) an ellipsoid keel having a horizontal plane mourned to the lower neck;
(viii) a fin-shaped appendage secured to an outer portion of the ellipsoid keel, and a moon pool formed in the hull;
(ix) a drill floor mounted above the main deck and the ellipsoid keel and around the moon pool;
(x) a marine riser stand penetrating through the main deck and extending toward the ellipsoid keel in parallel with the axis for containing a made-up marine riser;
(xi) a easing stand penetrating through the mam deck and extending toward the ellipsoid keel in parallel with the axis for containing a made-up casing;
(xii) a drill pipe stand penetrating through the main deck and extending toward, the ellipsoid keel in parallel with the axis for containing;
made-up drill pipe;
(xiii) a spire mounted to the hull with a cross bar; and
wherein each stand is oriented at an angle from 60 degrees to 120 degrees to the horizontal plane of the ellipsoid keel; and
wherein each made-up marine riser, made-up casing, or made-up drill pipe has a length from 50 feet to 270 feet;
b. a controller with a processor and computer readable media, the computer readable media comprising a vessel management system with priority zones for marine objects within the hull;
c. a vertically adjustable beam Intersecting hoist mounted to the crossbar proximate the moon pool and in communication with the controller comprising at least one dynamic intersecting support member;
d. an automated racking system mounted to the hull in communication with the controller, the automated racking system configured to install and remove the made-up marine risers in the marine riser stand and the made-up casing in the casing stand; and
e. an automated stand building system mounted to the hull in communication with the controller and adjacent the automated racking system, the automated stand building system configured to make up the marine risers, make up casing, and make up drill pipe from an angle from 55 to 125 degrees from the horizontal plane of the ellipsoid keel.

Abstract
A continuous vertical tubular handling and hoisting buoyant structure has a hull, a main deck, an upper neck extending downwardly from the main deck, an upper frustoconical side section, an intermediate neck, a lower neck that extends from the intermediate neck, an ellipsoidal keel and a fin-shaped appendage secured to a lower and an outer portion of the exterior of the ellipsoid keel. The upper frustoconical side section is located below the upper neck and maintained to be above a water line for a transport depth and partially below the water line for an operational depth of the buoyant structure. An automated stand building system mounted to the hull is in communication with a controller and configured to make up the marine risers, make up casing, and make up drill pipe.
