In order to meet the construction requirements, we determined the hauling ballast of specially profiled caisson through the caisson floating stability calculation, wall reinforcement calculation and model test. We used a combination of man-ual hoist and fine steel to alternative the crane ship installation process of specially profiled caisson, which can improve the ins-tallation efficiency and reduce the construction cost.
