Abstract

The invention provides a six-degree-of-freedom J-type pipe laying external centring device. The external centring device comprises a Y-axis platform, an X-axis platform, a pipe section bending platform, a body clamping base and pipe clamps, wherein the Y-axis platform is used for adjusting displacement of the six-degree-of-freedom J-type pipe laying external centring device in the Y-axis direction, the X-axis platform is installed on the Y-axis platform and used for adjusting the X-axis direction, the pipe section bending platform is installed on the X-axis platform to be made to rotate around the Y-axis platform, the body clamping base is connected with the pipe section bending platform to rotate around the X axis and move along the Z axis, and the pipe clamps are fixed to the body clamping base and can rotate around the Z axis. The external centring device meets all centring requirements of pipe sections for X-axis, Y-axis, Z-axis and circumferential rotation and pipe section bending.

Description

technical field [0001] The invention relates to a deep-water J-type submarine pipeline laying system, in particular to a J-type pipe laying six-degree-of-freedom external alignment device. Background technique [0002] In recent years, the scope of ocean exploration has been expanding, and deep-sea oil development has become an important frontier for the oil industry. Therefore, the laying technology of deepwater submarine pipelines is becoming more and more important. The J-type subsea pipeline laying system is currently the most suitable method for deepwater and ultra-deepwater pipeline laying. [0003] However, the marine pipelines laid in the J-type submarine pipeline laying system need to be adjusted and aligned before welding, so that the parts to be welded reach the best welding position. Therefore, it requires those skilled in the art to develop a device capable of adjusting and aligning the marine pipeline. SUMMARY OF THE INVENTION [0004] The technical proble...
