Abstract: The development of marine oil and gas resources is inseparable from the development and application of marine equipment. Flexible pipes and umbilical cables in marine equipment are the key equipment in the development of offshore oil and gas resources, and their safety and reliability is very important. Due to the multi-layer and spirally wound structural characteristics of marine flexible pipes and umbilical cables, the design and application of marine flexible pipes and umbilical cables need to rely on experimental testing techniques to ensure the safety and reliability of their applications. This article focuses on the experimental testing technology of flexible pipes and umbilical cables for offshore oil and gas development. It introduces the internationally used testing standards for flexible marine pipes and umbilical cables. Then through a large number of investigations, the key test types are explained in detail. It is hoped that the detailed description of the experimental testing technology of marine flexible pipes and umbilical cables can provide a certain reference for engineers in the field of marine equipment design, experimental testing and marine flexible pipeline, and umbilical cable application.
