Description
Dynamic power cable is a key component in development of large scale floating offshore wind farm. In order to ensure cost-effective operation of the power able, the configurations of the inter-array and the export cable need to be optimized through hydrodynamic response analysis together with local structural response analysis of the power cable. Failure modes of the power cable from manufacturing, installation, and operation must be identified and simulated properly through both numerical simulations and experimental investigations. This talk will present SINTEF's complete solutions from design, manufacturing, installation, and operation of the dynamic power cables. UFLEX will be introduced as a numerical cross-sectional software for stress and fatigue analysis of the power cable cross-section. JORDAN will be introduced as a simulation tool for loadout operation of the power cable with focus on torsional behavior of the power cable. SIMLA will be demonstrated as an advanced 3D cable laying simulation tool on uneven seabed. RIFLEX/SIMO will be presented as a global response analysis tool for configuration optimization of the inter-array and the export cable. Combination of UFLEX and CONCORDIA will be presented as a unique numerical package for fatigue analysis of helical components of the power cables.
Synchronizing cable responses caused by wave and current in time-domain will be a game-changer in future hydrodynamic analysis of the power cables. SINTEF's has been leading in developing time domain vortex induced vibration methodology both in numerical and experimental aspects. VIVANA in both frequency and time domains will be presented in the end as an innovative methodology for next generation simulation of dynamic offshore wind power cables.
