摘要
针对海上风电一体化安装技术中的浮运安全,采用海洋工程设计软件MOSES气垫模块对风电机组的自浮状态进行模拟.通过对船体及风电机组的各向加速度、位移及拖缆力等因素的模拟分析,研究了风电机组初始浮态对风机运输船浮运过程中动力响应的影响.结果表明:随着风电机组的吃水增大,运输船的浮运稳性变差,当风电机组吃水在4,m以下时,其吃水变化对风电运输船浮运的动力特性影响较小;可将4,m设为风电机组的安全吃水深度.在一定范围内,风电机组的筒型基础内外液面高度差越大,船体及风电机组在浮运过程中越平稳和安全.
To study the safety of the towing aspect of the integrated installation technology,the cushion block of the ocean engineering software MOSES was used to simulate the self-floating state of the wind turbine group (WTG).Through the analysis of acceleration,displacement,towing force and other factors of wind turbine transport ship and WTG,the effect of initial floating state of WTG was studied.The results show that the wind turbine transport ship is less stable during towing with the increase of the draft of WTG.When the draft of WTG is less than 4,m,the change in draft has little influence on the dynamic characteristics of wind turbine transport ship;4,m can be taken as the safe draft of WTG.The wind turbine transport ship and WTG are more stable during towing as the height difference between the inner and outer liquid surface of the bucket foundation of WTG increases within a certain range.
