Abstract
Some cofferdam systems have been applied for marine structures construction of bridges, marine foundation, and etc. Recently, new cofferdam system using large steel-cylindrical members proposed to reduce marine working periods and to improve economic of marine working. In order to construct marine cofferdam system with large steel-cylindrical members, (step 1) some modules composing of a large steel-cylindrical cofferdam system fabricate with typical height in steel factory, and (step 2) move to the construction site onto the barge towing. Then, (step 3) large steel-cylindrical cofferdam system completes by module to module connection with vertical direction in seawater. Finally, (step 4) inside water of large steel-cylindrical cofferdam draw out by pumping, and (step 5) the marine structures are constructed under land based conditions. This cofferdam system has advantages to reduce marine working period and to secure structural safety uniformly.
