Abstract: For the survey requirements of flexible pipes in subsea pipelines, CCS carries out research on the standards of flexible pipe, combined with survey experience, and composes the Guidelines for Survey of Metal Flexible Pipes Used for Subsea Pipelines, which would serve as the basis for surveys of such pipes. From the perspective of the difference between flexible pipe and traditional steel pipe in subsea pipeline system, this paper introduces the characteristics of flexible pipe in material, design, test, manufacture and installation, discusses the major requirements and technical background of the guidelines, and makes suggestions for further research.
