Abstract
The present invention relates to a gravity type oceanic structure and its stable installation wherein a skirt is provided downward on the outside periphery of the lower end of the part to be settled and fixed on the sea bed. When the structure is settled on the sea bed, the skirt is pushed into the sea bed foundation to intercept penetration of sea water from the circumference into the structure, and sea water in the skirt is adequately discharged by draining means to make the internal pressure equal to the atmospheric pressure. Buoyancy is thereby eliminated so that the bottom surface of the structure is fixed firmly to the sea bed.
