Abstract

PURPOSE: To permit the construction of a marine structure with a substructure of a large dimension in the sea bed by a dockby a construction method with an oil rig, etc., in which an independent strut to support a marine structure is fallen naturally by the weight of dead weight when floating the structure.
CONSTITUTION: The platform 1 of the marine structure body 2 can be towed on the sea water and has a triangle plane form the corners of which are thrust with three supporting feet 3 in a vertically movable manner. The supporting feet 3 has a triangle sectional form, whose lower end is provided with a spud tank 4 as a substracture. The marine structure is fabricated of a combined wall plate 6 provided at the bottom 5a of the dock and the independent strut 7, and when launcing is made, a dead weight 21 is attached to the middle of a cable 20 between the coupling metal 18 above the independent strut 7 and the coupling metal 19 of the dock bottom 5a, and then at the same time as the marine structure floats up, the independent strut 7 is fallen by the weight of the dead weight 21.
