Technology of Large-scale Cassion Shipped by Semi-submersible Barge with Trim by Bow and Crane Ship

In order to solve the problem that semi-submersible barge work stability could not meet the rule and the largest depth of submerged is not enough.This paper puts forward a method to make use of semi-submersible barge with trim by bow and crane ship to assist.The cassion shipping result shows that this method is practicable and has referential value for the similar cassion shipping.
