MANUFACTURING METHOD OF FLOATING MARINE STRUCTURES

摘要

PURPOSE: A method for manufacturing a floating offshore structure is provided to increase turnover ratio by reducing working time on a dry dock. CONSTITUTION: A method for manufacturing a floating offshore structure is as follows. Unit blocks of an upper structure(51) are assembled and manufactured in land. The unit blocks of the upper structure are transferred to a first marine dock(31). The upper structure are assembled and completed on the first marine dock. The upper structure is lifted above the first marine dock using multiple marine cranes(40) and moves the first marine dock to other position. A lower structure(52) is positioned under the upper structure. The upper structure is placed on the top of the lower structure.
