<p>PROBLEM TO BE SOLVED: To provide a construction method of an offshore building capable of constructing the same without relying on a large work vessel.SOLUTION: A construction method of an offshore building comprises: a presetting step; a towing step; a piling step; a launching; assembling and connecting step; and an installation and assembling step. In the presetting step, an offshore supporting device is installed on a catamaran type float. In the towing step, the catamaran type float with the offshore supporting device installed thereon is launched, floated above the sea with buoyancy of the catamaran type float and towed to a planned position. In the piling step, a plurality of fixing piles are driven into the seabed. In the launching, assembling and connecting step, the catamaran type floats is grounded on the seabed by filling the same with ballast water. In the installation and assembling step, installing and assembling works are completed by adjusting levelness of an apex surface of the offshore supporting device using a plurality of adjustment devices installed on tips of the respective fixing piles.</p> |
