Abstract

PURPOSE:To construct a large-type structure having a dimension exceeding the width of an existing dry dock in the dock, by a method wherein a marine structure is constructed on a floating body having a dimension exceeding the depth of a dry dock, and after completing the structure, the floating body and the structure are separated from each other on the sea. CONSTITUTION:A floating body 3 having the dimension exceeding the depth of a dock 1 is placed in the dock 1. The marine structure 4 is constructed on the floating body 3 by using a crane 2 or the like. Then, water is poured into the dock 1, the floating body 3 and the marine structure 4 are towed onto the sea, and the body 3 and the structure 4 are separated from each other by adjusting ballast. Accordingly, the large-type structure having the dimension exceeding the width of the existing dock can be constructed in the dock.

A method was taken. However, in the case of these conventional methods, there have been problems such as problems in the turning range of the crane and a decrease in manufacturing accuracy due to fluctuations in the purge.
