Abstract

PURPOSE: To lower the lift of a crane and perform the construction in good condition by a method wherin the lower structure body of a structure such as a working platform for a submarine oil filed and the like is built divided in half and half in a sidelong posture within a dock and then, being turned at a specified angle on or under water outside the dock, and the halves are joined to each other, etc.
CONSTITUTION: One half part 2b of a lower structure body is built in a sidelong posture and with its main-body posts 4b and 4d positioned away from the dock's side and in its longitudinal direction within the dock 10. Next, the one half part 2b is got out from the dock afloat, turned at 90° on the sea so that both main-body posts 4b and 4d may be positioned in a vertical line, and is balanced by providing a float 12 for balancing. The other half part 2a of the lower structure body is built and turned in the same way and both halves 2a and 2b are joined on the sea. Then a submarine barge is placed beneath the float 12 to lift the lower structure body above the surface of water and mount it on the tops 10a of both side parts of the dock 10, and after that an upper structure body is joined to the lower body.
