- Abstract
This article discusses the concept of assessing the risk of defects in offshore subsea pipelines according to risk criteria, taking into account the characteristics of methods and means of nondestructive testing used in practice. The expansion of the practice of assessing the danger of defects in pipelines according to risk criteria will clarify the assigned safety factors and increase the reliability of calculations of the permissible sizes of defects. The work describes the most promising methods of pipeline repair, and in their range, special attention is paid to the repair method using crimped composite sleeves, which performs repairs at an existing facility in real operating conditions. Based on the results of testing the proposed repair technology on a real object, the method repairs reliably most defects in the base metal and welded joints of pipelines for the entire service life and restores its full functionality.
