RISER JOINT WITH LENGTH ADJUSTABLE CONSTRUCTION

摘要

The present invention relates to a riser joint forming a drilling riser by interposing a pop joint (15). The present invention includes: a fixing part (20); an extending part (30) connected with an end of the fixing part (20) to slide; and a connecting member (40) maintaining a connection state of the pop joint (15) by being installed in the fixing part (20) and the extending part (30). Therefore, the present invention is capable of reducing a loading space of a drilling ship by replacing one pop joint, reducing costs for related materials, reducing time for the installation of the drilling riser on the ocean floor, and improving the operational performance of the drilling ship by increasing applicability for a variety of water levels.
