The invention discloses a ship special for pipeline laying in a shoal area, and relates to the technical field of offshore pipeline laying engineering. The ship comprises a ship body, wherein a pipeline laying tool is fixedly arranged on the ship body; the pipeline laying tool comprises a guide support, the guide support is provided with a guide sliding groove formed in the keel direction of the ship body, and the guide sliding groove is obliquely formed downwards from the rear end to the front end and extends downwards to the tail end of the ship body; a pipe supporting bracket extending outof the ship body is arranged in front of the guide bracket, and one end of the pipe supporting bracket is hinged with the ship body and butted with the guide sliding groove; a lowering mechanism usedfor lowering the pipe supporting bracket to enable the pipe supporting bracket to correspond to the inclination angle of the guide sliding groove is arranged on the ship body; a pipeline enclasping device is fixedly mounted between the guide bracket and the pipe supporting bracket, and the clamping center line of the pipeline enclasping device is parallel to the guide sliding groove; and a weldingstation is arranged on the guide bracket. According to the ship, construction technology is more efficient, the construction quality is better, stable and continuous pipeline laying operation can beachieved under the complex sea condition of the shallow water area, and the construction efficiency is improved.
