Parametric study of dynamic inter-array cable systems for floating offshore wind turbines

The rapid emergence of the floating offshore wind sector requires the development of new technologies such as dynamic inter-array cables. This work gives an insight into the hydrostatic predesign of such a cable system looking from side view. Numerical analyses are performed to compare two umbilical shapes, namely catenary and lazy wave shape. In a parametric study, water depth and cable length are varied. As outcome, a unique and generalized recommendation for a first umbilical design is presented. Finally, an outlook to the dynamic analysis of umbilicals in future work is given. © 2020, The Author(s).
