대형케이슨의 진수 안전성 향상을 위한 장비개선에 관한 연구

Abstract

This study is the case study for the large caisson integrated production and launching method in the port structure. This study proposes the improved safer method than the existing launching method which is composed of multi-integrated production system, horizontal shifting system and submergible floating dock. Therefore, the cases study and its analysis for the existing method of large caisson and launching method has been studied and analyzed and through the MOSES Modeling, the caisson compartment, Ballast concrete height, seawater height in the chamber and Floating Dock compartment has been carried out. The main results are as follows in the case study. 1) During the large caisson is being launched, the wave height could be limited to process the launching of Caisson and the tide shall be SWL and water stopper shall be installed to prevent water getting into the chamber. 2) The large caisson shall be launched within the initial draft height and Floating Dock shall be considered about trim during launching period. During the launching of large caisson, large area of caisson will be faced the sea wave, therefore most effect launching method should be considered. 3) In case the wave came from stern to bow, The large caisson shall be launched the vessel positioned parallel to wave direction. 4) Guide Frame is needed in order not to collided large caisson with Floating Dock. This study is the basic study for the large caisson construction and launching method. It is considered that this study can be used for the safest and the most effective method in large caisson construction and launching.
