Abstract
PURPOSE: To stabilize the work of fabrication of a marine structure, etc., without resorting to floating crane in proper sea region and secure safety by a method in which the heavy main parts of a marine structure, e.g., a seabed oil excavating rig, etc., are assembled in a dry dock for building a new ship and also the remaining parts for high level are assembled in a dry dock for repair work.
CONSTITUTION: For the fabrication of a landing elevator type working platform P, blocks 6 is placed on the bottom of the dock, the working platform 1 is floated from the bottom, and an assembled support plate 4 is placed in place under the working platform 1 and supported by the blocks 6. Then, an unit strut 2a is lifted by a goliath crane 7 and orderly engrafted to the upper part of the support plate 4, and after most part other than parts for high level has been assembled, water is charged intothe dock 5 to float the assembly by the buoyancy of an elevating base 1 and then towed to the repairing dock 5' by a tugboat. Then, the remaining parts of the strut 2 are assembled by operating a tower-shaped horizontal pull-in type crane 9. The crane 9, although its jib 9a can be raised up to the position 9a', can lift only small loads.
