Abstract

Shared mooring lines have demonstrated their effectiveness in reducing the installation costs of floating offshore wind farms by minimizing the requirement for multiple anchors. However, this innovation has also brought complex restoring properties and a greater tendency towards resonance. To tackle this challenge, this research presents a novel approach for shared mooring systems, implemented in a 2 × 2 orthogonal wind farm arrangement featuring 5 MW wind turbines installed on the Barge platform. Through the application of FAST and AQWA, a comparative analysis is conducted juxtaposing the original mooring (OM) and three new mooring models, namely buoy mooring (BM), clump weight mooring (WM) and buoy clump weight mooring (BWM). A comprehensive examination is carried out to assess the impact of on platform and mooring characteristics. The results show that the BM can effectively reduce the platform's surge and sway response, and that the mooring tension and laid length decrease as the net buoyancy increases. The WM increases the response amplitude at the yaw direction. The BWM with link buoys helps to improve the dynamic response of the platform and increases the length of the mooring laid. This analysis provides valuable insights for the design of floating wind farms incorporating shared mooring systems.
