The invention discloses a ship for laying pipelines underwater and a laying method. The ship comprises a ship body, a pipeline connecting device, in-pipe centering devices and a pipeline laying device, a welding support arranged on the pipeline connecting device is installed in a pipeline machining area, and the welding support is used for conducting welding machining on a to-be-laid pipeline placed in a pipeline placing area; a laying slideway arranged on the pipeline laying device is installed in the middle of the ship body, a laying frame arranged on the laying device is installed in a stern laying area, the rear end of the laying slideway is connected with the laying frame, a winch is installed at the joint of the laying frame and the ship body and connected with a furrow opener at the water bottom through a furrow opener traction rope, and a high-pressure water gun is arranged on the furrow opener; and the in-pipe centering devices are arranged at the ends of the laying slideway and the welding support correspondingly, and centering devices arranged on the in-pipe centering devices stretch into the joint of two pipelines to be welded. The ship body is small and is suitable for pipeline laying construction in shallow water areas; and the furrow opener realizes furrowing and pre-burying in the laying direction of the pipelines, so that the service life of the pipelines is prolonged.
