Abstract

A submerged tubular tower (10) is connected at its lower end (15) to an ocean floor (11) at a site where at least one subsea hydrocarbon well is to be drilled. A riser duct (22) for each well to be drilled extends from an up­ wardly accessible connection point (20) at the upper end (14) of the tower to the lower end of the tower. The tower is posi­ tively buoyant to stand erect in an unguyed manner. The upper end (18) of the tower is located a substantial distance above the ocean floor at a depth sufficiently small to enable wells to be drilled through the riser ducts, through equipment (19) landed on the top of the tower, using floating drilling equip­ ment (12) designed for use in substantially shallower water depths.
