Embodiment Construction

[0043] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0044] The present invention proposes a deep-sea pipeline motion simulation test system, such as figure 1 and figure 2 As shown, the device includes: motion support, offshore platform motion simulation system, working ship model, pipeline model, chart model, control system, test data acquisition and analysis system.

[0045] The described motion support includes a horizontal frame 1, four vertical support columns 2 and related control accessories. The four vertical support columns 2 are fixedly connected to the foundation, and the horizontal frame 1 is lapped on the four vertical support columns 2 . Under the operation of the relevant control system, the horizontal frame 1 can be raised and lowered, and can be automatically leveled, simulating changes in sea surface height, and then simulating different water depth environments.

Abstract

The invention relates to a simulation test method for laying and installation of a submarine pipeline. A simulation test system consists of a motion bracket, a marine platform motion simulation system, a working ship model system, a pipeline model, a chart model, a control system, and a test data collection and analysis system. During the simulation testing process, on the basis of a pipeline laying plan of a target project, a pipeline on a marine platform model is laid; the pipeline is led out from the marine platform model by a guiding device from top to bottom until the lower end of the pipeline arrives at a predetermined connection position of the chart model; fixation with a preset position of the chart model is carried out; if no pipeline winding phenomenon occurs, pipeline laying iscarried out based on the original laying plan; and otherwise, recording is carried out and the original laying plan is modified.

Description

technical field [0001] The invention belongs to the technical field of deep-sea oil development and transportation, and relates to a simulation test method for laying and installing submarine pipelines. Background technique [0002] Deep-sea pipelines are key equipment for deep-water operations, including offshore risers, submarine pipelines, offshore cables and umbilical cables, etc., which play a role in oil and gas transmission and operation control between offshore floating bodies and underwater production systems, and between underwater production systems. important role. In the process of deep-sea oil and gas development, each offshore oil and gas field project will have dozens or even hundreds of pipelines, including oil and gas transmission pipelines, drilling or production risers, cables and umbilical cables, etc., which are intricate. Considering the uncertainty of the marine environment, extreme sea conditions occur from time to time, and the pipeline system is e...
