Abstract
A self-propelled integrated ship for transporting and installing immersed tubes of an underwater tunnel comprises a first ship body and a second ship body which are parallel with each other, a connection structure is arranged between the first ship body and the second ship body; the first ship body, the second ship body and the connection structure are provided with hauling and hoisting devices, a loading space is formed between the first ship body and the second ship body and below the connection structure; a to-be-installed member is arranged in the loading space and is connected with the ship; and the first ship body and the second ship body are provided with propelling power devices and positioning devices. The loading space is provided in a lower part of the integrated ship, and a member to be transported is placed in the loading space and floated in the water, so that most of the weight of the member is shared by buoyancy. The member is transported to a designated site and installed precisely. Thus, the independent transportation and installation of immersed tubes of the underwater tunnel or similar large members with various sizes can be successfully realized by one self-pro…
