METHOD FOR THE INSTALLATION OF AN OFFSHORE MARITIME STRUCTURE AND OFFSHORE MARITIME STRUCTURE

COBIÁN IGNACIO

A method for the offshore installation of a construction laid by gravity on the seabed, comprising: the provision of a concrete base (1) delimited by a lower slab (8), a roof (2) and a perimeter wall (5), the interior whereof comprises vertical walls (6, 6′) forming cells (7, 12, 22); connecting at the periphery of the roof (2) a plurality of hollow metal floats (3) formed by a column with a circular or polygonal base; towing the assembly to the offshore location where the construction is to operate; allowing seawater to enter the cells (12) located below the roof (2), maintaining the cells (22) located below the metal floats (3) empty, in such a way that when the cells (12) located below the roof (2) are totally full, both the base and the metal floats (3) are submerged; once the cells located below the roof (2), but not those located below the metal floats (3) are full of water, allowing water to enter the cells (22) located below the metal floats (3) in such a way that the immersion of the assembly is completed, the base thereof resting on the seabed; and removing the metal floats. A gravity-based structure comprising a concrete base (1) and a plurality of hollow metal floats (3) connectable thereto.
