提出一种基于模块化浮码头进行半潜式风力机坐底式安装的新方案。综合考虑模块化浮码头的多体水动力耦合效应和风力机吊装过程的机械耦合效应,构建基于模块化浮码头的半潜式风力机安装过程耦合时域分析模型,对比研究典型海况下常规浮式风力机安装过程与新型坐底式风力机安装过程的动力响应特征。数值结果表明,模块化浮码头具有存放风力机吊装部件的良好性能;相比于常规浮式安装方案,坐底式安装方案的风力机基础展现出更好的纵摇和辅助夹具受力的性能。因此,基于模块化浮码头的半潜式风力机坐底式安装方案可适应更恶劣的安装作业海况,有利于提升浮式海上风力机的安装作业安全及全年有效作业时间。
Abstract
The article introduces a sit-on-the-botton installation approach for semi-submersible with turbines using modular floating docks. Considering the multi-body hydrodynamic coupling effect of the modular floating dock and the mechanical coupling effect of the wind turbine lifting process, a coupled time-domain analysis model of the semi-submersible wind turbine installation process based on the modular floating dock is constructed. The model is then used to comparatively investigate the dynamic response of the conventional floating wind turbine installation scheme and the proposed sit-on-the-bottom wind turbine installation scheme under the typical seas. The numerical results show that the modular floating dock has a good performance for storing the lifting components of the wind turbine. The wind turbine foundation of the sit-on-the-bottom installation scheme shows a better performance in pitch motions and auxiliary clamps compared with the conventional floating installation scheme. Therefore, the modular floating dock-based semi-submersible wind turbine bottom mounting solution can be adapted to more severe installation conditions, which is conducive to improving the safety of floating offshore wind turbine installation operations and the effective operation time throughout the year.
