ABSTRACT:
The invention is concerned with an improvement in the method of connecting pipe pieces incorporated in a node-equipped riser pipe interconnecting a floating facility and a sea bottom facility. A rocker pipe is connected through a swivel joint to each main pipe piece fixed to corresponding riser pipe piece. A relay pipe is disposed in a universal joint through which the riser pipe pieces are coupled to each other. The rocker pipes are connected to respective ends of the relay pipe through substantially U-shaped connecting pipes provided at their both ends with ball joints.
