Recommendations for mechanical testing of submarine cables for dynamic applications

The last years there has been significant development of the floating wind technology and floating wind is expected to grow fast in the future. This technology requires the use of dynamic cables that must be able to withstand the reoccurring motions induced by the floating device during its service life. The technical brochure written by WG B1.63 describes the design of the dynamic cable system, including the type of analysis that are performed as part of the design process. The brochure covers the test sequence for a dynamic cable with a special focus on the mechanical tests that are specific for a dynamic cable, for instance the full-scale fatigue test. The work has built on relevant standards from the oil and gas industry and existing CIGRE technical brochures.
