海管直线度及椭圆度水下测量技术

Underwater Measurement Technology for Straightness and Ovality of Submarine Pipelines

随着机械连接器和堵漏管卡在海管水下维修工程中的应用,海管直线度和椭圆度水下测量技术变得至关重要。文中介绍了海管直线度、椭圆度定义和允许偏差,以及海管椭圆度、直线度水下测量装置和技术,并分别概述各装置应用的优缺点,为海管直线度和椭圆度测量水下施工提供了参考。

With the application of mechanical connectors and plugging pipes in subsea pipeline underwater maintenance projects,underwater measurement technology for subsea pipeline straightness and ovality will become crucial.This paper introduces the definition and allowable deviation of the straightness and ellipticity of submarine pipelines,as well as the underwater measuring devices and technologies for the ovality and straightness of submarine pipelines,and summarizes the advantages and disadvantages of each device application.It provides a reference for measuring the straightness and ovality of submarine pipelines for underwater construction.
