Abstract

The invention provides a deep water submarine pipeline axial aiming machine, comprising a main body frame, an underwater robot connecting frame, a jointing device, clamping devices and adjusting devices; wherein the two sides of the bottom of the main body frame are provided with a foundation beam, the jointing device is respectively arranged on the foundation beams at the two sides, two cross beams opposite at the upper part of the main body frame are respectively provided with a clamping device and an adjusting device; and the upper part of the main body frame is connected with the underwater robot connecting frame. The machine clamps a new pipeline on a working mother boat, the machine and the new pipeline are dragged onto a designated H-shaped frame by an ROV, or the machine is directly dragged onto a new pipeline placed on the H-shaped frame by an ROV and then the pipeline is clamped by the clamping device, adjusting on the distance between the new pipeline and a butt pipeline and jointing operation are carried out with the coordination of a jointing tool, and meanwhile longitudinal position and transverse position of the new pipeline can be adjusted, so that the aiming accuracy of new and old pipelines can satisfy the requirement of bolt flange connection machine and deep water submarine pipeline butt quality is effectively improved.

Description

technical field [0001] The invention relates to offshore oil and gas development equipment, in particular to an axial alignment tool for deep-water submarine pipelines used in deep-water oil-gas pipeline connection operations. Background technique [0002] At present, oil and gas resources in deep water and ultra-deep waters are becoming a hotspot for the development of countries all over the world. Because oil and gas resources in deep waters need to be explored and developed in various ways, and offshore oil and gas development equipment directly determines the development level of offshore oil and gas resources, therefore , the research and development of key technologies and equipment for deep-sea oil and gas exploration has become an important task for the industry. [0003] The underwater tie-back of deep-water submarine pipelines is an important part of the deep-sea pipeline laying project. The initial alignment of the new and old pipeline networks in this project nee...
