Marine drilling platform pipe processing system and stand pipe connecting and transporting method

Abstract

The invention discloses a marine drilling platform pipe processing system and a stand pipe connecting and transporting method. The marine drilling platform pipe processing system comprises a derrick, an iron roughneck, a slip device and a pipe arranging device outside the derrick. The inside of the derrick is provided with a stand pipe connecting manipulator and a support manipulator, wherein the stand pipe connecting manipulator comprises a travelling block, a guide mechanism in the middle of the travelling block is provided with a rotating device, the bottom of the rotating device is connected with the top end of a mechanical arm through a hinge pin and connected with the base of a swing cylinder, and a clamping head is hinged to the bottom end of the mechanical arm. The marine drilling platform pipe processing system achieves gripping and vertical transportation of pipes, connection of stand pipes, and mutual transportation of the stand pipes among the outside and inside the derrick and the center of a wellhead; the stand pipes can keep a vertical state all the time during transportation, so that deformation of the stand pipes can be reduced, and the operational safety performance during transportation of the stand pipes can be guaranteed, energy consumption can be greatly reduced, and the operational cost of equipment can be saved.

Description

technical field [0001] The invention relates to the technical field of offshore drilling equipment, in particular to a pipe tool processing system for an offshore drilling platform and a method for connecting and transporting vertical roots. Background technique [0002] The exploration and development potential of offshore oil and gas resources is huge, and it is an important field for the strategic succession of oil and gas resources at present and in the future. Offshore drilling is a complex system engineering. A large number of advanced technologies are widely reflected on the drilling platform, which has the characteristics of high technology, high investment and high risk. In order to reduce the operating cost of offshore drilling, various measures will be adopted in the design of the platform to improve operating efficiency, reduce energy consumption, and enhance the safety performance of equipment. [0003] In terms of pipe handling, at present, deep-water offshore...
