J-shaped pipe laying ship

The invention relates to the technical field of pipe laying ships, and discloses a J-shaped pipe laying ship which comprises a ship body, a pipeline storage area, a pipe laying tower, a pipeline loading mechanism, a pipeline integration mechanism, a first crane, a second crane, a ship building and a parking apron, and the pipeline storage area, the pipe laying tower, the pipeline loading mechanism, the pipeline integration mechanism, the first crane, the second crane, the ship building and the parking apron are arranged on the ship body. After the ship body moves to a pipe laying area, the pipeline is transported to the pipeline integration mechanism through the second crane, the pipeline integration mechanism can lower the requirement for pipeline transportation accuracy, the pipeline loading mechanism can automatically center when lifting the pipeline to the position above the pipe laying tower and placing the pipeline on the pipe laying tower, the working procedures are saved, the efficiency is improved, a
