Numerical and Experimental Study of Hydrodynamic Response for a Novel Buoyancy-Distributed Floating Foundation Based on the Potential Theory

Abstract

Floating foundations play a vital role in exploring offshore energy. After analyzing various floating foundation concepts, this paper presents a novel buoyancy-distributed floating foundation (BDFF) inspired by the decentralized concept. The calculations of a floating system based on the BDFF design were performed for a series of wave conditions. The potential theory and the boundary element method (BEM) were used in the numerical progress. A broader view was focused on the impacts of wave frequency and wave directions on the system. The proposed floating system was further validated through wave tests in a wave tank, showing that the potential theory can satisfactorily predict the RAOs in regular waves. Moreover, numerical results and experimental results were compared with a conventional SPAR. Finally, the coupling relationship between six degrees of freedom was described.

A Review of Perspectives on Developing Floating Wind Farms

“…Hexa-Float [24], EOLINK, Nautilus [25], Tri-Floater, and Truss Float [11] are also floating wind semi-submersibles made of steel that have been developed by Saipem, EOLINK, Nautilus floating solutions, Gusto MSC, and DOLFINES, respectively. Sea Reed [26] is also a floating wind semi-submersible floating wind concept that is made of either steel or concrete (or both, in a hybrid) that has been developed by Naval Energies. The following sub-subsection presents the world's barge, TLP, and multi-turbine floating wind concepts.…”
