Application of suspended inter-array power cables in floating offshore wind farms

Failure Analysis of a Suspended Inter-Array Power Cable between Two Spar-Type Floating Wind Turbines: Evaluating the Influence of Buoy Element Failure on the Cable

“…The properties of the buoys are summarized in Table 4. The suspended interarray power cable configuration is established based on optimization studies conducted by Beier et al [8]. These studies focused on a two-turbine setup, which is consistent with the configuration employed in the present study.…”

“…Suspended Inter-Array Power Cable Setup 2.2.1. Power Cable Properties A three-conductor inter-array dynamic power cable from Beier et al [8] is used in the present study. The properties of the cable are derived with reference to the IEC standard [16].…”

“…The cable model in the present study is built based on the setup from Ahmad et al [1] and Beier et al [8]. They provided a detailed sensitivity study of the whole model (including boundary conditions, problem geometry, and mesh independence tests).…”

“…Because of severe motion by the FOWT, the element length is 0.2 m, and there are 50 elements for each HOP section. For free-hanging sections, the element length is 1 m. The element length for the bend stiffener section is 0.12 m. For the buoy section, the element length is 0.3 m. More detailed information of the model setup can be referred to Ahmad et al [1] and Beier et al [8].…”

“…Ahmad et al [1] explored the impact of buoy size in suspended configurations, concluding that smaller buoy sizes are more conducive to fine-tuning the arrangement and ensuring even tension distribution along the cable. Beier et al [8] investigated the effects of cable length, buoy quantity, and spacing on the maximum effective tension and minimum bending radius of the cable. The core main material of the cable is copper.…”
