A jack-up conical structure having a generally cone shape. The wide base and narrow upper section enhance stability of the structure during floatation, transport, elevation, anchoring, and drilling. The wide base along with a buoyant portion provide a large water line area which enhances stability of the structure during floatation and transit and while sections of the structure elevate and lower. The wide base also has shear resistance portion that prevents lateral sliding, especially in ice infested waters. A central shaft is disposed in a vertical orientation to the structure and facilitates movement throughout. A conical upper portion moves along the central shaft relative to the conical base. A drilling portion moves on racks of grooves inside the central shaft and performs drilling operations. Numerous chambers, cranes, and helipad support drilling and habitation on the structure.
