Abstract

The present invention is of a deepwater platform which incorporates a central two-piece tower extending from the ocean floor to at least a few feet above the ocean surface. The central tower is divided into an upper tower section and a lower tower section, with the lower tower section being substantially higher than the upper tower section. The tops of outwardly and downwardly positioned struts are connected to the tower at the dividing point between the upper and lower tower sections. Both the lower end of the central tower and the lower ends of the struts are anchored to the ocean floor by driving piles through pile sleeves secured thereto. The dividing line between the upper tower section and the lower tower section depends upon the angle at which the struts are positioned against the tower.
