| Pipe plugging technology is a major and key technology to solve subsea pipeline leak,with the production and science developing swiftly, people’s demand for oil is becoming moreand more high. However, the leak of oil in the passing process is inevitable. Through theanalysis of domestic and international plugging technology development as well as thecomparison several kinds of pipe plugging devices, this text designs a special plugging systemused for subsea pipeline leak.At the basis of explicit analysis of specific design data, I propose a general scheme forthis plugging system. I carry out a series of study, including mechanical body structure,hydraulic system and control system. Among I design clamping part, lifting part and swellingpart specifically. After I analyze two kinds of clamping plans, I select a most outstandingpipeline clamping plan in the end. I also check all the parts intensity by Ansys, consequentlyall the parts intensity meet the demand. Because of complexity of seafloor and in order toreduce the pressure, I drill a few holes on some parts and then conduct Ansys analysis.Through Observation of stress and Strain diagram, their intensity still meet the demand. At thesame time, carrying on stress analysis of Cone-shaped sleeve and swelling sleeve, besidescam, and having designed cam outline. After designing and choosing types for Hydrauliccomponents, the total Hydraulic schematic picture is drawn.Considering the complexity of plugging equipment workflow, in the end of article,carrying out Kinematics and dynamics Simulation Analysis of plugging equipment andanalysis of Simulation curve, thus feasibility of plugging equipment is tested. |
